Product quality Winners and losers in the New Zealand plumbing product marketplace.
IT’S GREAT TO see reputable plumbing products being recognised at the annual New Zealand Plumbing Awards. This year’s winner was Marley Twist®—a clever rainwater diverter that turns your downpipe into a source of water for the garden, cleaning or emergency use. NZ Plumbing Conference attendees got to see and handle many other excellent newly launched products and services during the two-day trade exhibition. If you couldn’t make it to Hamilton for the event, turn to p74 for a sample of what was on show. Sadly, not all products conform to such high standards. As Colleen Upton says in our feature article on p12: “There are actually sales guys out there hawking tapware and the like, who are bold enough to ask you to your face: ‘What brand or standard do you want us to put on this product?’ Naturally, this stuff comes at a good price, but only fools would go there!” Colleen is expressing her concerns about overseas substandard plumbing product being imported unchecked into New Zealand—and she’s not alone. Gasfitter Howard White has similar concerns about unstamped glass being used for splashbacks behind gas hobs in our article on p48. In the list of plumbing industry issues that Master Plumbers wants the Government to address as a matter of urgency, this is priority number one… and no wonder. So, let’s hear it for those in the industry—manufacturers, suppliers and installers—who set the bar high. The very best were recognised at the 2018 New Zealand Plumbing Awards, and we feature them on p37.

MASTER PLUMBERS NEWS
Plumbing industry issues A number of key plumbing industry issues were discussed at our recent meeting with Building and Construction Minister Jenny Salesa. IN MASTER PLUMBERS’ view, there are four priority issues that require urgent attention: the quality of plumbing products available in New Zealand, plumber self-certification, current skills shortages, and Standards funding. Before our meeting, we provided a detailed briefing to the Minister, putting forward possible solutions to these issues. With regards to product quality, we believe New Zealand needs to follow Australia’s lead and legislate point of sale compliance, which would require evidence from merchants and resellers that their products comply with New Zealand Standards. We feel it is unfair and unreasonable to expect plumbers to be able to identify issues with products, such as potential lead contamination in pipework and tapware. We have also raised our concerns about this with Consumer New Zealand, and they have agreed to investigate the possibility of product research and testing. On the matter of plumber selfcertification, we find it staggering that less than 50 percent of consented plumbing work actually gets physically

inspected in some areas—and yet the industry must still pay consent fees. It seems nonsensical that a gasfitter can certify all his or her work, but a plumber must undergo sometimes as many as three inspections before sign off. Looking to Australia once more, plumber selfcertification has been in place for 12 years and there is a robust audit process to ensure compliance. To the third issue, the Minister acknowledged that MBIE data showed a significant shortfall in qualified tradespeople. She said consideration was being given to a government-led initiative that would require trade businesses to have apprentices among their staff in order to be able to tender for government-funded projects and public private partnerships. Lastly, we addressed the workload and cost involved for Master Plumbers in helping develop and maintain Standards for the industry as a whole. We asked the Minister to review the current funding model, as we don’t believe it is sustainable or serving the construction industry well. We believe these issues for the plumbing sector should be considered separately from a wider construction industry review—particularly, plumbing product quality due to possible consumer health risks. The Minister expressed a desire to
have a strong working relationship with Master Plumbers, and our feedback will be sought on any draft papers that result from our discussions. On a different note, we are thrilled to have negotiated an increased fuel discount for members. Following a threemonth tender process with three major suppliers to ensure we are delivering the best possible value, we have secured a new deal with Mobil, providing members with 12 cents off diesel and petrol at the pump price or 20 cents off diesel at national price (more details on p9). As part of this initiative, all members will receive a Mobilcard, which will double a membership card. Members will also be able to use a barcode on the back when purchasing other discounted products from our discount partners, such as Hirepool and Pit Stop. Finally, a big thank you to everyone who attended and supported the New Zealand Plumbing Conference. To have more than 300 people attend the awards night is outstanding and proves our industry is in great shape.

20 years at Master Plumbers Marking a team milestone. Company Accountant Christine Robertson has been on the Master Plumbers national team in Wellington for 20 years—a milestone worth celebrating, we think! Christine joined Master Plumbers in March 1998, in the days when the national office was based in Taranaki Street, George Verry was the CEO, and Master Plumbers also owned the ITO. Since then, Master Plumbers has moved to its current premises on Ghuznee Street, the ITO has become the independent Skills Organisation
and Master Plumbers has established Masterlink Ltd, the group apprentice training scheme. Masterlink accounts management takes up a good deal of Christine’s time, as does NZ Plumbers’ Journal Ltd—both separate companies under the Master Plumbers group umbrella. “Every day is different,” says Christine, whose other roles include handling Master Plumbers finances, budgeting and staff salary payments—as well as looking after the finances of the Master Plumbers branches.
“I also liaise with IRD and Stats NZ representatives, our bank, auditors and tax agents, and ensure deadlines are met on financial reporting to CEO Greg Wallace, the Master Plumbers Board and management team,” she says. Congratulations to Christine for two decades in this busy and vital role for Master Plumbers!

IN FOCUS
Small but perfectly formed? Tiny houses and pods are construction buzzwords. Ross Miller investigates what this growing trend means for the plumbing industry. “SOLVING THE NATIONAL housing crisis is a massive task and one we are rolling up our sleeves and getting on with.” So said Housing and Urban Development Minister Phil Twyford in March. A recent independent stocktake of NZ housing has revealed population growth outstripping housing stock growth by 2.1 percent between 2012 and 2017. Net migration has ballooned from 32,853 to 262,762 between the 2007-12 and 2012-17 periods, with Auckland growing at a rate of 40,000 a year. More homes need to be built, and quickly—and, according to the report, the Government’s KiwiBuild programme will “help develop new innovative approaches”.
Prefab solutions Prefabricated housing is one potential solution that’s attracting plenty of interest—particularly in Auckland. If metropolitan area growth is to be kept out of Auckland’s surrounding high-value horticultural area, it either needs to go into high-rise living, or small housing on small sections, or communes of tiny houses especially suited to singles or older couples. Pods and tiny housing are well suited to prefabrication, which has the advantages of speed, accuracy and on-time building.
this is still emerging technology and there are lots of conversations to be had
Membership organisation Prefab NZ has conducted research that shows New Zealand already has the off-site capacity to deliver high-quality homes for KiwiBuild, without the need to look overseas. Members say they could deliver around 7,000 more homes each year from 2020, which would deliver 70% of KiwiBuild’s target of 10,000 homes per year over 10 years. Manufacturers and builders surveyed said they were ready to reinvest around 8% of revenue, and up to 20% in some cases, to deliver KiwiBuild. “This is astonishing news,” says PrefabNZ Chief Executive Pamela Bell. “New Zealand housing manufacturers and builders are telling us that they are willing to forego some profit in the short term to deliver KiwiBuild. This research is economic proof that our innovative construction industry does not need a big multi-national outsider in order to deliver on the KiwiBuild promise.” “We can have several New Zealand businesses using innovative building methods working together, using homegrown materials and sharing specialist expertise. For example, different companies might make wall panels, or roof pieces or bathroom pods, or any of the elements that go into a building.” Celebrity architect Tommy Honey is among the growing number of people in the building industry getting behind the idea of prefab housing. He is creating an online network called Slimby that will enable homeowners to earn money from their unused back sections. Slimby stands for ‘shared living in my backyard’ and would see homeowners rent prefabricated granny

that, for everyone’s protection and peace of mind, there needs to be certification that the made-up product conforms to local regulations, so there is a clear line of responsibility over that and the installation or connection of the made-up building or pod.”
Product and consent concerns People would be amazed at some of the product that is available in New Zealand, says Colleen. Some pipe and product produced in China can be stamped with whatever the purchaser requires (eg, NZ Standard etc), and it is not even close to the required quality. “There are actually sales guys out there hawking tapware and the like, who are bold enough to ask you to your face: ‘What brand or standard do you want us to put on this product?’ Naturally, this stuff comes at a good price, but only fools would go there!” Another concern, says Colleen, is that a mini house put together in Christchurch to local territory authority regulations, may not conform to Bay of Plenty regulations. “We cannot delay this. Approval has already been given for one community of locally-produced mini houses. The need for this housing is real and urgent, so we have some catching up to do on the compliance side for everybody’s protection.
“We look to government departments like MBIE to give some guidance and direction to our industry, as well as our colleagues in other regulated industries. For example, will sparkies be happy to connect up pods or prefab housing where they haven’t had a chance to inspect the wiring? Will they be prepared to certify it? “Also, where do council inspectors’ responsibilities start and finish? There is no pre-line inspection. The concern is that the responsibility will be pushed down to those subcontractors who need the work and who don’t want to draw a line in the sand and say, ‘Show me the proof that this has been done to code and regulations using quality products that meet the appropriate standards’.” Master Plumbers CEO Greg Wallace says the organisation has voiced its concerns to MBIE about plumbing inspections for pods and other factory assembled modular housing. “We want to see the same approach to inspections for this kind of housing as for houses constructed in the traditional manner, and MBIE has promised to come back to us with clarification,” he says. “Master Plumbers has no problem with the concept of prefab buildings. We just want to ensure that houses made and assembled overseas have the necessary New Zealand plumbing certification and approvals.” ■
Snug as a bug PrefabNZ is currently running a SNUG competition to design a small ‘back garden’ dwelling—“somewhere that can be a home for your children as they adventure out into independent living, a safe place for extended family members, or a work-space”. The aim of the competition, it says, is to “open up the conversation about alternative housing options”. The winning one- or two-bedroom house prototype could be ‘pre-consented’ by Auckland council, or indeed any council, as part of a solution to the housing crisis. The competition has a $10,000 prize pool and was launched by architect Tommy Honey. The Snug design parameters are to create a well-designed prefab ‘accessory’ dweling unit that can supplement an existing residential property. It has to be: • • • • • •
self-contained unit between 30m2 and 65m2 (65m2 as per Auckland council minor dwelling definition) suitable for Auckland single house and mixed housing (urban and suburban) zones offsite construction/design for manufacture and assembly consideration for living, sleeping, kitchen, bathroom, laundry, utility and storage spaces concept design for marketing and judging purposes, towards a ‘pattern-book’ of Snug solutions designed for manufacture with construction drawings and details.

quickly on existing backyards. Obviously there will be major demand for add-on infrastucture, so plumbers will be busy if this happens. The key to pre-fab’s advantages is volume—and that is where the industry will be looking to the Government for surety to promote investment. Fletcher Residential, for instance, is interested in participating in the market. “Kiwibuild offers an opportunity for developers to get this kind of visibility and surety over future pipelines, and we are excited to see the Government is looking at a range of delivery options for the initiative over the next decade,” says CEO Steve Evans.

Wheel appeal
The freedom of bike travel, and a desire to support suicide awareness, saw this Kiwi couple’s OE extend to include an 18-month cycling tour. By Helen Murdoch. PLUMBER CAMERON SMITH, 28, and his partner Monique Nees, 27, left Clyde in September 2014 armed with two-year visas and plans to live in London, working, travelling and visiting family. All too quickly their time was up. “We wanted to travel a lot more when our visas ran out,” says Cameron. Initially, they decided to cycle for five or six weeks, riding to a music festival in Budapest, Hungary—but it didn’t stop there. They eventually arrived home just before last Christmas, having covered 33 countries and completed a three-month tour of New Zealand. “We loved the freedom to travel and do what you wanted, so
everyone has been affected by suicide in some way
we just kept making it up as we went along,” he says. Meeting another couple who were fundraising while travelling gave them the idea to do something similar—interacting with local schools and communities on suicide and mental health. Monique graduated from the University of Otago with a Bachelor of Applied Science focussing on public health, with her final thesis on youth suicide. Both she and Cameron have lost school friends to suicide, and Monique has also lost family members. “Everyone has been affected by suicide in some way, so it was a natural progression,” says Cameron. So, KiwiBums on Bikes was born—and the mission to cycle home to Alexandra via Cape Reinga and Bluff. In total, they travelled over 30,000 kilometres, taking back roads and meeting people from a whole range of different cultures and walks of life.

Conversations with communities about mental health and suicide really ramped up when they reached New Zealand, says Cameron. “We were blown away how people we met on our tour spoke about suicide and mental health and were aware of it. “And that is the main goal: to normalise conversations, so it is spoken about openly to enable people to feel comfortable reaching out. “As a youth growing up in a rural community I was lucky and never had suicidal thoughts. But, looking back, there was never a comfortable way to express yourself if you did.” >

Money can only help so much when talking about mental health, he says. Travelling made him realise how lucky New Zealanders are and question why our country has such an issue with suicide and mental health. “I used to be a bit of a straight shooter and believed you made your own luck. But you don’t know people’s circumstances and what is going on in someone’s head—and you need to be aware and open to it.” Now Cromwell based, Cameron is busy keeping up with his plumbing workload while Monique studies for her Masters, with the aim of teaching health and wellbeing in schools. “When we were in Australia we talked about saving and doing another trip, but we are enjoying being home,” he says. “We’ll get out on the bikes again, but it might be a shorter journey.” The couple’s Givealittle page, along with sales of merchandise by friends owning Dunedin’s The Print Room and Auckland’s Monday Roots, raised around $5,000 for the Life Matters Suicide Prevention Trust. ■

Wetback cylinders Servicing cabinet heaters Handling the pressure?
TECHNICAL THEME
Wetback cylinders David Waite of Rheem outlines the differences between copper and stainless steel wetback cylinders. Copper cylinders
The traditional way to store water heated from a wetback fireplace is using a low pressure storage water heater. This wetback copper hot water cylinder has extra connections, allowing a direct feed from the wetback firebox heat exchanger to the cylinder via flow and return pipes. The gradient on these pipes is important, so G12 and the manufacturer’s instructions must be followed to ensure safety and best performance (see Figure 1).
Above: Figure 1—Low pressure wetback layout.
Stainless steel coiled cylinders
Stainless steel mains pressure cylinders suitable for wetbacks are gaining in popularity (see Figure 2). This type of cylinder is fitted with an internal heating coil. The water heated by the wetback fireplace is circulated through the coil in the cylinder rather than directly into the cylinder. The coil circuit must be open vented because the water in this circuit is being heated by an uncontrolled heat source. The open vent needs to be located from the highest point of the coil, and a header tank or pressure reducing valve must be used to replace the water lost in the coiled system. The water inside the cylinder can operate at normal mains pressure, like a standard mains pressure cylinder. The coil design is important so that the hot water from the fireplace can naturally thermosiphon without the aid of a pump, and stratify in the cylinder. As with low pressure wetback cylinders, it is important to follow the manufacturer’s instructions. With a mains pressure wetback system, the potable water and water in the coil never mix. However, because of the low volume of water in the coil and circuit, the maximum wetback heater output is limited to 3kW. The stainless coiled wetback cylinder has many advantages, including being able to deliver mains pressure water at the outlets, and can be placed higher in the system to get better flow and return from the wetback fire, as the pressure at the tap is not reliant on the open vent low pressure system or header tank.
Inserted inside the cylinder is an inlet copper riser extending almost to the top of the cylinder. This assists with stratification of the hot and cold water. The size of the riser is determined by the size of the cylinder. Just like standard low pressure cylinders, a header tank or a pressure reducing valve must be used to reduce the mains pressure to standard low pressure (76kPa). However, a wetback copper cylinder must be open vented as it is supplied by an uncontrolled heat source, which is directly heating the potable water in the cylinder.

Servicing cabinet heaters The LPG Association’s Guide for Cabinet Heater Servicing includes a servicing procedure for gasfitters to follow. CABINET HEATERS NEED regular servicing and, if used frequently, an annual service is ‘prudent’, advises the Guide for Cabinet Heater Servicing (LPG Association Code of Practice No.4). The Code of Practice describes procedures for periodic servicing to ensure safe operation throughout the appliance’s working life.It also gives guidance on servicing facilities and equipment, and repairs—plus provides samples of a typical cabinet heater servicing report and appliance service label. Here we look specifically at the servicing procedures in the Code of Practice.
Stop Press
The Government will be consulting later this year on minimum heating standards in rental properties, and seeking feedback on the types of heaters landlords can provide in rental properties. Master Plumbers wants to see cabinet heaters and other portable unflued gas heaters banned from use in residential properties. Read more about this in the next edition.
Customer and heater information Record details of the customer, the appliance and its condition as shown on the Service Report Form (sample given in Appendix C of the Code of Practice). Visual inspection of appliance Check and record that the dressguard (mesh screen for catalytic appliances) and appliance panels, including rear panel, are firmly attached. If any are missing or damaged they must be replaced with authorised spare parts. For radiant heaters, check and record any fault or damage found in relation to pilots, burners, ceramic plaques or fireclay cement. Any such damage requires repair in accordance with the manufacturer’s instructions. For catalytic heaters, check and record any fault or damage found in relation to pilot or catalytic panel. Any such damage requires repair. On appliances more than five years old, check if there is evidence of the pilot being replaced in the last five years. If there is no such evidence, the pilot will require verification or replacement in accordance with the manufacturer’s instructions. Depress the igniter several times and make sure there is a reliable spark from the ignition electrode. If there is no spark or it is erratic, the appliance requires repair. Record the date of manufacture stamped on the regulator and printed on the hose. Record if there is dirt or corrosion on the appliance. Internal cleaning Remove the front or bottom kick plate. Radiant heaters Clean the tops of main burner injectors and pilots with a soft paintbrush, taking care not to cause damage to delicate items such as pilot shutters. 22
April/May 2018
If they cannot be cleaned in this manner then they must be repaired or replaced. If the pilot is damaged in any way it must be changed. Pilots cannot be unblocked or repaired without affecting their calibrated cut-off point. If possible, cover the tops of jets and pilot (masking tape is ideal for this but take care with other types of tape), and blow out the inside of the appliance using compressed air. Eye protection and respiratory protection must always be worn when doing this. Ensure the plaque ports (holes) and venturis are clean of dust, dirt and fluff/lint. Take care not to damage ceramic plaques, particularly soft ceramics and flame effect beds, electrodes and pilots. When the appliance has been thoroughly cleaned, replace the front or bottom kick plate. Catalytic heaters Clean the top of the pilot with a soft paintbrush, taking care not to cause damage to delicate items such as pilot shutters. If they cannot be cleaned in this manner then they must be repaired or replaced. If the pilot is damaged in any way it must be changed. Pilots cannot be unblocked or repaired without affecting their calibrated cut-off point. Use a vacuum cleaner to clean the inside of the appliance.
Ensure the appliance is clean of dust, dirt and fluff/lint. Take care not to damage the catalytic panel, electrodes and pilots. In no circumstances should the heater be blown out to remove dust as damage to the catalytic panel could occur. A vacuum cleaner with a high efficiency filter must always be used. If the face panel mesh has been dented or pushed inward, then pull or spring it out to the original position. When the appliance has been thoroughly cleaned, replace the front or bottom kick plate. Hose replacement Note: The hose and regulator assembly on a cabinet heater must be permanently fitted to the appliance (ie, fastened with crimp type hose clamps at the hose connections to both appliance and regulator). Screw or worm drive hose clips are not acceptable. The hose should be replaced by a similar length of new approved LPG hose to BS3212, AS1869, ISO 2928, ensuring the hose is long enough to fit the regulator on to the cylinder with the cylinder outside the appliance, if it is: • Unmarked or not marked with any of the approved standards; • Damaged, chafed or worn; • More than five years old. To remove the hose, undo screw or worm type clips or use pliers to cut crimp type clips and then shave the hose along the length of the tail(s) sufficiently to allow the hose to be pulled off the tail. Do not cut with the point of a blade. Damage or score marks on the surface of the tails may cause leaks. Discarded hose should be cut into small lengths to prevent re-use. When fitting hose, it should be pushed fully over the nozzles of the appliance and regulator and must be secured firmly in position with correctly sized crimp shells or eared (Oetiker) crimp rings. Regulator replacement See Note in previous section. The regulator must be replaced using an approved clip-on or QCC type LPG regulator having an outlet pressure of 2.75kPa (28mbar) and of a type appropriate to the gas cylinder in use if it is: • Damaged; • Showing signs of corrosion; • Not of a type appropriate for the gas cylinder; • Not date marked on the regulator body or cover • Not an approved type • Over 10 years old. Note that the use of POL regulators is not permitted with cabinet heaters. Remove the regulator by cutting the hose as close to the regulator nozzle as possible, if the hose is to be re-used. When attaching the hose to the regulator it should be pushed fully over the regulator tail and secured firmly in position with correctly sized crimp shells or eared (Oetiker) crimp rings. If a new regulator is fitted, the customer must be given any instructions that were provided with the regulator. >

Gas check Note: The appliance must be operated with the bottom panel on, as absence of the panel may affect the performance of plaques (or catalytic pad) or pilots. Radiant heaters Connect the appliance to a full LPG cylinder using the appliance regulator fitted. Check for smooth ignition when the appliance is operated in accordance with the manufacturer’s instructions. If the appliance does not light or cross light smoothly, it requires repair. Check that the flame supervision device ‘holds in’ within 20 seconds. If there is a problem with ‘hold in’, check that the thermocouple nut into the control is tight. Check for free smooth and correct operation of the control. If it is difficult to operate, the appliance requires repair. Set the control to the HIGH position and let the appliance warm up for five minutes, then observe the appearance of the plaques. If they show flare, are dull or show a blue, the appliance requires repair. Catalytic heaters Connect the appliance to a full LPG cylinder using the appliance regulator fitted. Check for smooth ignition when the appliance is operated in accordance with the manufacturer’s instructions. If the appliance does not light smoothly, it requires repair. Check that the flame supervision device ‘holds in’ within 20 seconds. If there is a problem with ‘hold in’, check that the thermocouple nut into the control is tight. Check for free smooth and correct operation of the control. If it is difficult to operate, the appliance requires repair. Set the control to the HIGH position and let the appliance warm up for five minutes, then observe the front face of the catalytic panel. On most appliances the panel will have to be viewed through the facing mesh, as this may not be easily removed; subdued lighting may make inspection easier. Inspect for bright spots, damage and wear, such as holes, ‘bald’ patches and cuts. If the panel shows such features, then the appliance requires repair in accordance with the manufacturer’s instructions. Check for leakage A leakage check should be carried out whenever a heater is presented for service or repair, and must be carried out when any components are removed and replaced. Check that all unions are tightened and that internal pipe work is undamaged. Connect the appliance to a gas supply, light the appliance, select HIGH setting and check all joints of gas carrying components for leakage, using a soapy water solution and soft brush, or electronic sniffer. Rectify any leaks as necessary and retest. Flame Supervision Device Drop Out Time (FSD) When the appliance has warmed up, turn off the gas supply at 24
April/May 2018
the regulator or cylinder valve. The time until the FSD is heard to click shut should be measured. The time for the FSD to close will normally be 30-50 seconds. Sixty seconds is the maximum allowance. If the flame supervision device takes more than 60 seconds to close, the appliance requires repair. After the FSD has closed, turn on the gas at the regulator or cylinder valve and check that no gas is passing to the burners by attempting to re-light with a taper. If gas passes to the burners, the appliance requires repair. Turn off the gas, and disconnect the regulator. Oxygen Depletion Sensor (ODS) pilot In the absence of instructions to the contrary, provided for the ODS pilot by the manufacturer, consideration should be given to replacing the ODS pilot if it is over five years old. It is essential that the pilot/thermocouple/electrode assembly is undamaged and clean, and their relative positions are correct. If the thermocouple and/or the spark electrode are substantially obstructing the pilot orifice, the pilot life will be delayed. Any obstruction will act as flame retention and in this respect the thermocouple tip will have greater effect than the spark electrode because it is larger. Misalignment should have been detected in carrying out the ‘Gas check’ and ‘Flame supervision check’. If necessary, adjust the electrode but check that a reliable spark which will light the pilot is still obtainable, and that the thermocouple is not positioned too near the plaques, nor touching the top of the pilot. Castors and door catch Re-align and/or replace each component as necessary. Final preparation Clean the appliance thoroughly. Secure the regulator with tape to the valve or door to prevent it rattling around and causing damage in transit. Complete and affix an appliance service badge (sample given in Appendix D of the Code of Practice). It is strongly recommended that persons servicing cabinet heaters maintain a true and correct record of work carried out. This may be a carbon copy or photocopy of the customer sheet and repair record, or it could be a separate logbook. Note: Special requirements for catalytic heaters When completing the general information form, it should be noted that after 10 years of normal service, the heater will be near the end of its serviceable life and should not be subject to further servicing. In this case, recommend that the customer should purchase a replacement. Catalytic heaters produced before 1983 may be fitted with an asbestos-based catalytic bed. Any work involving asbestos is subject to health and safety regulations, which require that suitable precautions are taken to control exposure.

Handling the pressure? CENTRAL HEATING NEW Zealand’s technical team has supported heating engineers and plumbers on more than 6,000 projects nationwide. Installing a new heating system is a straightforward process, but there are still one or two ‘grey areas’ where installers require additional support or advice—expansion vessels being one of them. In the past, central heating systems had header tanks to cope with the thermal expansion of water. These days, most installations use an expansion vessel. The advantage is that system water is not exposed to air, which reduces levels of corrosion. Also, the system can be pressurised, which is better for pumping fluids and eliminating air locks. An expansion vessel is a chamber with an internal rubber diaphragm. On one side of the diaphragm is heating system water; on the other side is pressurised air via a Schrader valve. From factory, the air side of the expansion vessel is pressurised to 1 bar. The expansion vessel is then connected to a heating system, preferably on the cooler return water side. When a heating system is filled with water to a pressure of 1 bar, the expansion vessel is in equilibrium, as both water and air sides of the diaphragm are equal pressure. As the system heats up, the water expands and the diaphragm moves to accommodate the expansion. When the water cools, the diaphragm retracts and the expansion vessel maintains pressure, with the air pressure acting like a spring.
Installation
The majority of heat sources include an expansion vessel that covers typical system expansion requirements for the output and water temperature of the heat source. It is critical always to check if the vessel is correct for your system water volume and pressure relief valve vent rating. Often, on a larger system, an additional expansion vessel will be required to maintain correct system pressure throughout the heating cycle. If the expansion vessel volume is too small, the pressure relief valve will vent, resulting in a system pressure drop and eventual system failure. System water volume is easily calculated from the radiators or underfloor Above, from top: An expansion vessel attached to a central heating system system. If in doubt, contact (cold) and an expansion vessel in your central heating system operation (hot). 26

provider, who will help you correctly size the vessel and offer advice on upgrades and replacements.
Checking vessel integrity
On an annual service, it is recommended to check the expansion vessel. This is a good indicator of how the system is operating. A common mistake is to check the vessel air pressure without dropping the system water pressure to zero. This is the correct method and must be done when the system is cold. A simple car or bike pressure gauge and pump are used to check and add pressure at the Schrader valve. Ensure the system water pressure is then topped up to equal the expansion vessel air pressure (for example, 1.0 bar). An internal system or pipework leak can be another cause of pressure loss. Don’t be tempted just to keep topping up. It’s a bad idea. You continue to feed the leak, which introduces air into the system via fresh water, and you lose the chemical inhibitor that protects the system from the inside. Over time, this leads to a build-up of corrosion within the system. In Europe, expansion vessels are also used on hot water cylinders, with the same principle of absorbing water expansion, with huge savings in energy and water consumption. Clean green NZ could adopt this approach!

Clean slate
Younger staff at Foley Plumbers got to work with traditional plumbing materials on this Dunedin heritage project. By Matthew Lowe. Slate artistry
The firm has had three people at the site, along with the builders, since about March 2017. It has also exposed other employees to the intricacies of working with old-fashioned slate tiles and plumbing materials. “You don’t get to do a lot of this type of work nowadays and young guys would not normally see lead work and slating—there is a real art to it,” Craig says. “You have got to take your time with them, you can’t rush it. They are great materials to work with and having a craftsman slater with experience [in such work] helps. “People are retiring and if they do not pass on these crafts they are going to be lost. We have been introducing guys to the slate and lead work so they can get that experience because they may well never see it again—but if they do they will know what to do and how to do it well. “Being part of this project helps their understanding of how things work, because with a slate roof it is very much about how

MAKING A HISTORIC priory watertight has been embraced by a plumbing company as a chance to expose its younger staff to working with materials rarely used these days. Foley Plumbers in Dunedin has teamed up with Stewart Construction to help protect the city’s Dominican Priory from the elements. The priory was built in 1877 and was the home of Dunedin’s Dominican nuns for more than 100 years. However, in recent times the building’s condition had deteriorated and the Catholic Diocese of Dunedin decided to repair the slate tile roof, and replace copper and lead rainwater disposal systems. The $900,000 project, which is almost complete, also involves earthquake strengthening parts of the Heritage New Zealand category one building. Craig Foley, director of Foley Plumbers and the firm’s Dunedin hub manager, says the builders had to replace a lot of timbers before his staff could tackle the slate work to stop rain entering the priory.

After the Dominican Sisters left the Priory in 1983 it was sold to an anonymous member of the church and, in 1988, the property was gifted to the Catholic Diocese of Dunedin. A developer from the North Island had been interested in purchasing the building in 2005, but that deal fell through and it has mostly been vacant since. Craig, who is also national Chairman of Master Plumbers, says the priory had “been empty for a long time, except for pigeons” and little of the original plumbing work around the roof has been retained. His team had 30,000 slate tiles shipped from Wales for the job, the first of which arrived last July. > Above right: About 30,000 slate tiles were shipped from Wales for the project.

“We had to import the slates from Wales mainly because of cost effectiveness. The type of slates we needed, because they come in different sizes and grades, had to be good quality,” he says. “We are also replacing the guttering and valley gutters and spouting and tidying it up. What was there was not flash, so it is all being replaced. It is going back to heritage stuff and that is swapping like for like. It is new copper and lead and goes back to the building’s old look. “There are challenges given its heritage status but our craftsman slater is very good at what he does—we have got the expertise to do this kind of job.” Previous work on slate roofs by Foley Plumbers has included buildings in Dunedin belonging to the University of Otago. The 70-room priory achieved the distinction of being the largest non-reinforced concrete building in the Southern Hemisphere when it opened.
Members of the diocese hope a ‘cosmetic clean’ and the work to prevent water damage to the building will lead to interest for people wanting to buy the property. The roof work and earthquake strengthening, which had Salmond Reed Architects as the heritage architect on the project, is all the diocese has committed itself to at this stage and it is not planning to undertake further work on the building’s interior. “The new slate roofing and associated plumbing works have been mainly funded with grants from New Zealand Lotteries Commission, Otago Community Trust and the Dunedin City Council Heritage Fund,” says Bill Haydon, Catholic Property Services property manager. “Without their generous support, the work to the roof would not have been affordable by the Dunedin Diocese.” ■

Mighty Waikato! Each day of the 2018 NZ Plumbing Conference contained a packed and engaging agenda. Wednesday Claudelands in Hamilton was the setting for the 2018 NZ Plumbing Conference this March. A short walk across the Waikato River from the Novotel and Ibis Conference accommodation, it was a spacious venue for the speakers, technical workshops and trade exhibition. It was also the base for the PGDB & Mico CPD training session. Held on the opening day, this was followed by the Master Plumbers AGM (see p34). From there, attendees got their first glimpse of the large trade expo during the Master Plumbers and Allproof KickStart Happy Hour, with the Mico Welcome Night buffet dinner under the vines at Vilagrad Winery providing a convivial end to the first day. Thursday Two-time Olympic Gold winner Eric Murray passed his medals around the audience while speaking of the huge amount of planning and perseverance required to reach goals, whether in sport or business. Eric was followed by BNZ Chief Economist Tony Alexander, who engaged the audience with his take on New Zealand’s current ‘capacity constrained economy’, which has seen 14% growth over the past four-year period, compared to the 2.6% average over the past 25 years. The decline in dairying has been offset by booming sectors, such as construction and tourism, he said—and by population growth. “We are no longer a country from which young people get out.” He sounded a note of warning about the false impression that everyone is moving out of Auckland to the regions. Some regions are pulling out all the stops to build new residential housing, but may be risking over-supply. Presentations from PGDB Chief Executive Martin Sawyers and Skills Organisation Head of Engagement Di Lithgow followed, with concerns raised from the floor about training provider performance and a desire to see the ITO collaborating more closely with the industry. Leadership expert Dr Lester Levy spoke about the difference between leadership and management. Anyone can hold the helm when the sea is calm, he said, but it takes leadership to deal with turbulent times when the course is uncertain. Wrapping up the day’s speaker sessions was Hamilton-based WorkSafe Assessor Brent Austin, who highlighted the health risks from working with asbestos, silica dust and solvents. The Marley Fun Night Dinner at Hobbiton provided the perfect end to the day, with guests in hobbit attire taken on a tour of the movie set, followed by a lantern-lit buffet dinner.

Friday The final day began with an update from Hamilton East List MP Jamie Strange on behalf of Building and Construction Minister Jenny Salesa, who was unable to attend. MBIE projects included ‘smarter compliance pathways’, occupational regulatory reform and, of course, KiwiBuild. There would also be a comprehensive review of the current building product assurance system, he said. He took away audience questions for the Minister relating to plumbing self-certification, modular housing, skills shortages, apprentice training and a need for more uniformity among councils. Jamie Fitzgerald spoke next, sharing his learnings about achieving peak performance though his ocean-going and Antarctic adventures. Having a shared purpose and a clear goal are critical to success, he said. Rounding off Friday morning was a choice of technical trade sessions in plumbing, drainlaying and gasfitting, with plenty of open discussion on common issues. In the afternoon, Master Plumbers’ members could opt to attend a business workshop from BNZ Head of Small Business Harry Ferreira or enjoy the Mobil Leisure Afternoon Activities. Another full day came to an end with a talk by Darrel Hadley of local success story Good George Brewing, followed later by the 2018 New Zealand Plumbing Awards Dinner, sponsored by Plumbing World.

PLUMBING CONFERENCE 2018 21-23 MARCH, HAMILTON
Membership matters Performance for the Master Plumbers group was discussed at the Society’s Annual General Meeting.
DELEGATES FROM Master Plumbers Branches and Associations attended the national Annual General Meeting on 21 March.
President’s report In 2017, four Associations had become Branches and seven were in transition. In his report, National President Rod Miller noted that the new Branch format had a more relaxed feel, in not having to be as structured as Associations. He thanked Associations and Branches for inviting him to their meetings during 2017. “I think all regions have enjoyed a very busy and demanding year, with the main issue being staff shortages—and we all know the only way to fix this is to employ more apprentices,” he said. Rod also noted that Master Plumbers was in a “very good space with new members, innovative IT systems, and good marketing plans”.
Directors’ report Chairman Craig Foley said the Society had been busy meeting members’ needs in 2017, through member support, representation, advocacy, training, Quality Assurance, communications and marketing, branding, and the expansion of the Business Partner programme. He noted that health and safety was a priority for the sector. CEO Greg Wallace and the Board had undertaken to assist members in areas such as advocacy and resources, he said. These included the Master Plumbers Health & Safety Manual and apps for reporting. “I would also like to remind members that agreeing to the Code of Conduct is a fundamental part of being a Master Plumber,” he concluded. “It is there to assist us all in delivering a high level of service to our customers.”
CEO’s report CEO Greg Wallace said Master Plumbers’ advocacy work had increased rapidly towards the end of 2017 with the change in Government. “There is now a new environment to work in, and plenty of ministerial meetings planned to ensure our industry is at the forefront of construction-related developments.” The Master Plumbers’ brand had been further strengthened during 2017 with the decision to carry out ongoing face-to-face Quality Assurance reviews of a random selection of at least 15 percent of the membership, said Greg—noting that Quality Assurance reviews were an added-value resource that aligned 34

with the Master Plumbers motto of ‘Representing Excellence’. Master Plumbers would continue to work with the Plumbers, Gasfitters and Drainlayers Board to ensure qualified tradespeople were acting competently and in compliance with NZ law, he said. Greg concluded by thanking the Board and staff along with all Master Plumbers’ Business Partners. “We couldn’t provide services to members without our Business Partners,” he said.
Masterlink “from strength to strength” This Master Plumbers’ subsidiary was established 16 years ago to increase the number of high calibre apprentices in New Zealand as well as to provide a return to Master Plumbers for the benefit of all members. The company performed well in all regions in 2017, said Mark Whitehead in his Masterlink report. Two new Regional Managers had started in Auckland, and a new National Business Manager role had been created to assist the Regional Managers in a time of growth within the business. A new Business Development Manager for Master Plumbers and Masterlink had also been appointed in the South Island. There had been a continued focus on health and safety during 2017, which had added some costs to the business, as with many other businesses in the sector. “Continuing improvements are being made to Masterlink’s health and safety practices and reporting, giving the company the ability to track incidents and implement solutions,” said Mark. Initiatives during the year had included the successful introduction of an online apprentice payroll system, a new hazard-reporting feature for the apprentice health and safety app, and a new health and safety software package, which would further improve reporting in 2018. Numerous meetings had been held with government officials and TEC, NZQA, Skills and MBIE representatives to discuss concerns about nationwide training providers—resulting in agreement by TEC and Skills to undertake a full review, said Mark.
NZ Plumber “a real asset” Chairman Craig Foley noted that NZ Plumber magazine was a real asset, which had year on year added to the bottom-line income for the Master Plumbers group. He thanked Master Plumbers’ Business Partners for their ongoing support of the magazine. In 2017, NZ Plumber had become a New Zealand Magazine Media Awards finalist in three categories—one of only two construction-related magazines in New Zealand to reach the finals. A free digital version was available to all members, giving them access to the magazine on their desktop or mobile devices. “The magazine provides its nationwide readership with relevant articles on business, technical and human-interest topics, along with news from Master Plumbers, Masterlink and the industry at large,” said Craig.

The 2018-19 Master Plumbers Board In 2018, John DeBernardo, Martin de Gouw and Bruce Trenwith were due to retire by rotation as Directors of the Board of Master Plumbers, Gasfitters & Drainlayers NZ. John and Martin offered themselves for re-election. Bruce Trenwith decided not to stand for re-election, and was thanked at the AGM for his many services to the Board, including his time as National President from 2013-2015. “The more you give, the more you get out of Master Plumbers,” said Bruce. In the first-ever electronic ballot for the Society, members voted in John DeBernardo, Martin de Gouw and Jon Lewis for the three available positions on the 2018-19 Board. The full Board comprises: • Grayson Allen • John DeBernardo • Martin de Gouw • Craig Foley • Jon Lewis • Rod Miller • Dave Strong • Mark Whitehead.

PROJECT OF THE YEAR 2018 The winner is: Optum Ltd The Glenorchy campsite on the shores of Lake Wakatipu had become very run down following multiple bankruptcies and a lack of infrastructure investment. The Camp Glenorchy project saw it completely transformed, becoming registered under the Net Zero Energy Certification pathway. Camp Glenorchy has been designed with a goal of using 50 percent less energy and 50 percent less water than standard visitor accommodation facilities. Optum Ltd was engaged to install the plumbing and drainage for the project, as well as the heating and solar—with most, if not all, the building’s energy to be solar-powered. Composting toilets at the camp save approximately 30,000 litres of water each year. All rainwater is collected in three large in-ground water tanks, then pumped and filtered for irrigation, and UV treated to NZ drinking water standards for the potable water supply. Optum Managing Director Kevin Henderson is very proud of his team working on the project for carrying out highly complex

KAVA CUP 2018 Congratulations to Conference hosts, the Waikato Master Plumbers Association, for winning this year’s Kava Cup for their community involvement on the Chartwell Scout Hall in Hamilton.

REAL LIVES
Collecting memories IN HIS PRIVATE museum in Dunedin, Roger Herd keeps a veritable treasure trove of memorabilia. Brightly painted early 20th century petrol pumps stand beside rows of children’s pedal cars and a selection of clockwork toys. Enamel advertising signs from the 1950s decorate the walls, and lamps of all shapes and varieties hang from the ceiling. Some items were purchased at auction, others through word of mouth and yet more from Trade Me—and all were bought here in New Zealand. Amongst all the memorabilia stored in the fully insulated (and virtually dust free) museum, there is also space for a motorised pushbike and a couple of vintage cars: a rare coachbuilt 1927 Roadster and an Austin 7 built in third scale. The car restorations started it all, says Roger, who shares his hobby with a group of friends who all help each other out. “A collector came out to look at my Austin and said my garage could do with some signs and stuff.” Roger took him at his word, and soon the pedal cars followed (“I put it down to a deprived childhood!”). There are now at least 40 of these in his collection—some restored and others waiting their turn. His favourites, though, are the old petrol pumps, which he has restored from scratch—taking them apart and putting them back together again. Dating from 1911 to the 1960s, the pumps
A love of vintage cars started Roger Herd on his passion for collecting memorabilia, including old plumbing tools and fittings.

REAL LIVES
clockwork toys stand on a table, ready to be wound up and set in motion make a magnificent display, with their large glass globes, shiny brass fittings, enamel paintwork and hand-painted signwriting. He says he got the first one 15 years ago and now has more than 20 in various states of repair. “I’d come across them on farms, and get my staff to help haul them back in pieces, so I could build them in here. They’re extremely heavy, as they have cast iron bases.” Roger’s collection extends to the family home—though Lynn keeps a watchful eye to ensure it doesn’t extend too far… Here, myriad clockwork toys stand on a table, ready to be wound up and set in motion, thanks to Roger’s meticulous restoration work. “Everything is in working order,” he says. For example, there’s a monkey who shoots a ball into a hoop, a pair of fairground boxers who throw punches, a ferris wheel that turns, a cross-legged man who puffs on miniature cigarettes and a young boy who walks along carrying a suitcase. Roger’s four-and-a-half-year-old grandson loves to come over and see all the toys, but he’s very careful not to touch without his granddad’s permission. Roger is going to have more time to work on his collection with retirement beckoning, but he says he’s not going to extend the garage space—he’ll just become more selective. Only time will tell… ■

50 years in the industry A plumber’s bicycle in Roger Herd’s museum gives a clue to his background. The bike bears the name of A&T Burt, the company where Roger started as a plumbing apprentice 50 years ago. At the time, A&T Burt was one of the biggest national plumbing and plumbing supply companies in the country. Roger stayed there for around 37 years, rising through the ranks and seeing several changes in owners. By the time he left, it was Chubb Fire and Services, and Roger was the Services Manager, managing a staff of 10. A dedicated member of the plumbing industry, Roger joined the Otago Master Plumbers Association around 25 years ago, serving a term as President. He went on to serve on the national Master
Plumbers Board, including one term as national President. His involvement with the Master Plumbers Masterlink group apprentice training programme began in 2003, when he became a part-time coordinator for Otago/Southland. He went full time five years later, and is set to go part-time in his role as Masterlink South Island Manager later this year. He is a passionate supporter of apprentice training, and has grown Masterlink sign-up numbers in his region from around four when he started to the current 70-plus. Roger has won the New Zealand Outstanding Services to the Industry Award twice—once in 2008 and again in 2018 (see p37).

Our latest round up of gasfitting news. Withholding gas certificates
Gas installations in caravans
Public comment was recently sought on a draft amendment to the caravan installation code, which seeks to standardise compliance plate requirements across Australia and New Zealand. Two changes were proposed in the draft: 1. A change to the warning labels that will need to be applied near cookers. 2. The introduction of a new requirement for the placement of a ‘Gas Compliance Plate’ when gasfitting. The compliance plate will indicate whether it is a new installation or an alteration and will identify the caravan, the gasfitting certification number and the gasfitter certifying the installation. These types of compliance plates are already required in some states in Australia for both caravan and domestic installations. There are no immediate plans to make this requirement part of the regulatory regime in New Zealand, but Energy Safety believes it will provide a way for consumers to be able to determine the compliance of their vehicle. The current gas installation standard for caravans and boats is AS/NZS 5601 Gas installations—Part 2: LP Gas installations in caravans and boats for non-propulsive purposes: 2013.
Need to make a notification?
Did you know you need to notify Energy Safety if you discover a dangerous gas installation? Any person carrying out gasfitting who has grounds to believe that a gas installation or gas appliance presents immediate danger to life or property must advise Energy Safety and the owner or occupier of the property. If a property owner has given permission to undertake the repair of an immediately dangerous situation, and a practitioner is not able to carry out the repair that day for any reason (including workload), notification to Energy Safety must still be undertaken as soon as reasonably practicable. If a practitioner finds a gas appliance or installation is noncompliant, no notification needs to be made to Energy Safety. Find the installation fault notice form at www.energysafety.govt. nz/forms/installation-fault-notice-form

Master Plumbers recently sought legal advice from Duncan Cotterill on whether or not gasfitters can withhold a gas certificate or PS3 form until they have received payment from the client. In summary: • They consider that a PS3 could be withheld until payment is received, because there is no specific statutory requirement for a PS3. • They do not recommend withholding gas safety certificates for non-payment because: ° there is a statutory requirement to issue these certificates as soon as practicable, but at least within 20 working days; and once the certificate is issued there is a requirement ° to provide a copy to the person who contracted for the work or the owner/occupier of the property, within a further 20 working days. Producer statement (PS3 – Construction) On completion of building work, an owner must apply to the district or city council for a code compliance certificate certifying that the building work has been carried out in accordance with the building consent. The PS3 is routinely used by councils as part of the evidence that the work complies with the consent. Neither the Building Act 2004 nor the standard application form for a code compliance certificate make any specific reference to a PS3. However the application form does refer to “other documents from personnel who carried out the work”, which could be said to include the PS3. This general reference is in contrast to other documents that are expressly required under the Act. Duncan Cotterill consider that if there was a legal duty to provide the PS3, it would have been specifically referred to in the legislation. “In support of this position, we note that the Plumbers, Gasfitters and Drainlayers Board indicate on its website that they will not look into issues around the provision of a producer statement as a disciplinary offence that they can consider,” says Nick Crang at Duncan Cotterill. “However, it would also be worthwhile for gasfitters to check contracts carefully to ensure they are not agreeing to terms that would require them to provide the PS3 prior to being paid.” Gas certificates The position is different for gas certificates. An application for a code compliance certificate must include an ‘energy work certificate’. This includes a gas safety certificate, issued after gasfitting installation work has been completed. The person doing the connection or their supervisor must issue a gas safety certificate as soon as practicable after the installation is connected to a gas supply, but no later than 20 working days after the connection.

Once issued, the issuer must provide a copy of the gas safety certificate to the person who contracted for the work or the owner/occupier of the property, within a further 20 working days. Given the express legislative requirements to issue and provide a gas safety certificate, and for it to be included with an application with a code compliance certificate, Duncan Cotterill do not recommend that these certificates be withheld where the client has failed to pay for the work. Gas certificate infringement notice In its March newsletter, Energy Safety also reminded gasfitters and electrical workers that they must supply certificates for gasfitting and installation prescribed electrical work (PEW) to the person who commissioned the work within 20 working days. “This reminder comes after we audited a gasfitter’s certification of gasfitting following a complaint that a gas certificate hadn’t been received after work had been completed. “We found the gasfitter had not issued a gas certificate within 20 days of connection to the gas supply, and it was only issued once contacted by us. “The subsequent issued certificate contained several faults. The gasfitter was issued an infringement notice for breaching Regulation 50(c) of the Gas (Safety and Measurement) Regulations.”
Gas hob clearances and splashbacks
There has been a change in the reference standard for sourcing information on clearances and suitable materials for splashbacks installed adjacent to gas hobs, noted BRANZ in its March Guideline. The new reference document is AS/NZS 5601.1:2013 Gas installations – Part 1: General installations. For splashback requirements, use Table C1 on page 148. For the most common splashback materials, the requirements are: •
•
•
• •
(750mm for an exhaust fan) splashback heights – not less than 150mm above the periphery of the nearest burner side or back clearances to the splashback – if less than 200mm, the surface shall be protected in accordance with clause 6.10.1.2, which is summarised above.
For full details, always refer to the Standard.
Caravan & motorhome self-containment
Over the summer months, the Plumbers, Gasfitters and Drainlayers Board (PGDB) received several enquiries about self-containment certificates for caravans and motorhomes— particularly in regards to if and how plumbers can certify caravans and motorhomes for self-containment. In its latest InfoBrief, the PGDB explains that correct selfcontainment helps ensure there is adequate provision for the containment of waste water created by the use of the caravan or motorhome. This, in turn, helps freedom campers have minimal adverse effect on the environment, it says. Unlike gasfitting, plumbing in a caravan is generally not restricted work. This is because work on sanitary fixtures and appliances in vehicles is excluded from the Plumbers Gasfitters and Drainlayers Act’s definition of sanitary plumbing. “However, NZS 5465:2001 allows registered plumbers to certify for self-containment,” says the PGDB. In order to certify for self-containment, plumbers should purchase a copy of NZS 5465:2001 and follow the requirements outlined in the Standard. Plumbers will need to issue a certificate and warrant card as per the requirements in the Standard.

Splashback standards
Unstamped glass splashbacks can make it hard for gasfitters to sign off gas hob installations, as Matthew Lowe explains.
REQUIREMENTS FOR TOUGHENED safety glass splashback installations adjacent to a gas hob are given in AS/NZS 5601.1:2013 Gas installations – Part 1: General installations (see item on p47). However, ensuring the glass used is actually toughened can be tricky, because some manufacturers no longer stamp their products with a safety mark.
Gas hob installation Gasfitter Howard White, from LB White Ltd in Lower Hutt, raised concerns about the absence of safety stamps after having to turn detective to verify whether a some glass splashbacks installed by gas hobs conformed to New Zealand’s rules. The dilemma first arose when he went to approve work done at a Wellington home last year. “One of my guys installed a gas hob and then the homeowners installed a splashback and I went out sign off the job,” Howard says. When he got there, however, he was unwilling to certify the work, as there was no stamp etched on the splashback to show it was made of toughened glass and fit for purpose, as required by the Standard. “The homeowner had bought the glass from [a hardware store] and had got the paperwork as to where it was made and a phone number of the NZ importer. I rang them and they said they had got certification documents for the glass, which was made in China, and they sent them through. “The documents said the glass complied to the NZ Standard but how are we to know when there is no stamp on the glass to prove it?” Howard says the importers told him the glass was not stamped because it was being used for “cosmetic-decorative purposes and consumers wouldn’t like it”. They sent him a copy of the Chinese manufacturer’s certificate of conformance—for AS/NZS 2208:1996, which covers toughened glass—issued by third party certification company based in Australia. Howard encountered a similar problem this March with a splashback made in New Zealand and installed in a Lower Hutt home. “We’re not disputing that the glass is up to standard, but we are saying it should be marked—and that is clearly not happening in many cases,” he says. “If something happened where there was a problem with the splashback, all I have got is a letter from the company saying they only use toughened glass for their products.”

Non-permanent marking The Glass Association of New Zealand (GANZ) and Ministry of Business, Innovation and Employment (MBIE) both say toughened glass should usually carry a permanent stamp mark, but there are instances where a non-permanent marking or supporting documentation is acceptable. Splashbacks are among glass items used in buildings that must meet certain requirements before people are allowed to use them due to the extreme heat they can be subjected to. Brett Francis, GANZ Chief Executive, says the use of toughened glass for glass splashbacks is a requirement under the gas industry’s rules.
NUTS & BOLTS
“Generally, glass companies will stamp the glass. This however is very hard to see on painted glass and some companies will apply a removable sticker,” he says. Brett urges gasfitters who have any concerns about a splashback to ask to see a certificate of compliance from the supplier or installer. He says the association would like to see a greater level of focus by officials and industry on the use of correctly marked safety glass. “Showers etc are covered by NZS 4223.3:2016 [Glazing in buildings – Human impact safety requirements] and are all required to be marked with the minimum of name of manufacturer or supplier, type of safety glass, the standard it’s tested to, and the licence or identification number provided by a third party compliance certifier,” he says.
Advising the client “If no marking is present [in a splashback] we’d recommend any tradesman make the client aware in writing. This is then traceable in the case of future issues. “The consequences of using non-marked glass are varied, from the simple no code compliance certificate being issued, to product failure with little or no come back on the supplier/ installer—potentially leaving the end user out of pocket. “Liability would generally sit with the installer; therefore using a recognised specialist like a GANZ member gives a greater level of security.” An MBIE spokesperson says if safety glass conforms to an industry standard it is required to bear a stamp mark, identifying the standard it conforms to. “In most cases the mark must be permanent but in some cases a non-permanent marking may be permissible,” he says.
Advising the BCA “Under the performance-based Building Code, a building consent authority (BCA) could accept the use of safety glass without markings if it is satisfied about the origin of the glass and the manufacturer’s quality assurance.
“If (within the scope of a building consent) a tradesman notices glass that they believe should be toughened glass but is not marked, then they should notify the relevant BCA. If a building consent is not being assessed, a tradesman should seek additional information to satisfy themselves that the product meets the relevant standard or code requirement.” The spokesperson adds that tradespeople installing glass products have a duty of care to ensure the work they do meets the requirements of the Building Code or of the legislation they are operating under.
A common concern? Howard eventually signed off the two jobs after being advised by industry figures to make a note of his concerns in the job brief and to attach all the relevant documentation he had received about the glass. “The suppliers said the glass complied, but for my gas certification it was hard to be fully confident that it does,” he says. “I’m concerned there may be a lot of splashbacks like this out there and we may not know if this glass really complies. If it doesn’t carry a New Zealand Standard stamp how can we know if it is kosher? “Only being supplied with documentation from a firm in China certainly raised a few alarms for me so I imagine other gasfitters must have hit the same problem.” Addressing Howard’s concerns about the potential for belowpar products to be coming from overseas, MBIE says it does not monitor the importation of building products. “Under New Zealand’s performance-based Building Code, different products and construction methods can be used as long as compliance with the code can be achieved,” the spokesperson says. “Suppliers and importers also have a responsibility to ensure that the products they sell to consumers comply with the relevant provisions of the Building Code.” ■

Can you taste it? Water chlorination questions answered by Noel Roberts, Technical Manager at Water New Zealand.
“All these different forms can be used to treat drinking water supplies. Gas is certainly the most efficient and costeffective form because it is 100% pure and contains no other products. The liquid form can be only 1% chlorine, so you have to then use a lot of it—and what’s the other 99%?”
CHRISTCHURCH’S WATER IS being chlorinated, meaning all of the country’s major cities now have chlorinated drinking water supplies. The garden city’s move came less than two months after the damning results from an inquiry into our drinking water were released. So why do we chlorinate our water? Is it a controversial additive like fluoride? And what else do we need to know? Noel Roberts, Technical Manager at Water New Zealand, a non-profit organisation focused on the water sector, has answers to the ins and outs of water chlorination.
What sort of concentration of chlorine is needed?
This depends on the original quality of the water. “The Drinking-Water Standards do have criteria and the minimum dose is .2mg/L (ppm). The maximum is 5mg/ L(ppm). I don’t know anywhere in New Zealand that is up around the 5mg/L (ppm) mark.
What’s chlorine put into drinking water supplies for? “Chlorine is the last barrier of protection, if you like. It will pick up bacteria, viruses and some protozoa. Protozoa are giardia and cryptosporidium—but chlorine won’t do anything for crypto. These are pathogens. They come from either humans or animals.”
if there are no bugs in the water, you won’t smell the chlorine
What’s the benefit of chlorine?
“Treatment processes like ozone and UV will treat everything that goes past them. But if it gets re-infected further down the track by, for example, a leaky pipe or vermin getting into a reservoir, or someone’s hydroponics getting back into the water reticulation somehow, the chlorine provides a residual disinfection. “That’s where chlorine has a really big bonus over other forms of treatment.” You can still treat with chlorine at the same place as other forms of treatment but it will remain in the water supply. Ozone and other forms only work as the water passes through.

April/May 2018
How many layers of protection are there?
“There are many, including physical filters and membranes, as well as ozone and UV treatment.”
How much does chlorination cost? “It’s the cheapest and most cost-effective protection to put in place. “There are three different ‘flavours’ of chlorine as well. You can get it as a gas. You can get it as a potable liquid form (similar to Janola), and you can also get it as a powder, like is used in some swimming pools.
Can you smell it or taste it in the water?
“If there are no bugs in the water, you won’t smell the chlorine, as it isn’t doing anything.” “It’s only when it’s actually doing something that you can smell it. So it depends on how clean your sources are and the other treatments upstream whether you’ll get any odours.” Roberts says the majority of the population would not be able to taste the chlorine. Three per cent of the population are ‘supertasters’ with very sensitive tastebuds, he says, and they would likely be able to taste it. A very small number of people have allergies to chlorine. It can be removed at point of use by a carbon filter.
At what concentration would chlorine have to be to be dangerous to people?
“Over 5 grams per cubic metre. Swimming pools are typically in the 2-10 range. So they are certainly up there with those rates.
NUTS & BOLTS
there are very few first world countries that don’t chlorinate “But the drinking water standards are based on a lifetime effect. So I guess if you spent your life in a swimming pool, it might be a different story. “But for drinking water, levels are based on no ill effects at all.” The drinking water standards are based on an average person consuming two litres of water per day over a 72-year lifespan, with one in 100,000 people becoming ill.
How much does chlorine reduce risk of illness?
“With the exception of cryptosporidium... as long as there is enough chlorine there... it is believed to kill all other pathogens, bacteria and viruses.”
Who’s responsible for treatment and monitoring? “The water supplier. Some contract it out.” For example, Watercare does it for Auckland Council and City Care for Christchurch.
Is chlorination an international standard?
“There are very few first world countries that don’t chlorinate all their water supplies. The few that don't have really, really high engineering standards— higher than in New Zealand. Examples are Germany and the Netherlands.”
Are there major cities or towns in New Zealand that are without chlorination? “Yes there are. They are rapidly
decreasing. Napier was, Lower Hutt was, Hastings was—they are about to change as well. Queenstown.
Safe drinking water The major and most common water quality concerns in New Zealand arise from microbiological contamination of the source waters, according to the Institute of Environmental Science and Research (ESR) website at www.drinkingwater. esr.cri.nz. Animal, bird and even human effluent can make water unfit for consumption. Bacteria have always been of major concern, while protozoa such as giardia and cryptosporidium are increasingly being highlighted as causing ill health through drinking water. The Ministry of Health, through the provision of standards, guidelines and other tools, is tasked to ensure that an appropriate infrastructure is present to support the provision of clean and safe drinking water. The Health (Drinking Water) Amendment Act 2007 gives the framework for ensuring safe drinking water is provided. However, the water supply owner is responsible for monitoring water and
ensuring supply is safe. For larger supplies that’s usually the city or district council. For private supplies it’s the owner. About 87% of our population receives drinking water from local authorities, according to the Office of the Auditor General. A Government inquiry into drinking water released in December 2017 revealed 2% of water supplies were not up to standard. Internationally we do not compare well. “Public supplies in England and Wales, large Finnish supplies, and Scottish Water have all had greater than 99.8% compliance with E coli standards from 2011-2015,” the report found. Water in New Zealand is graded as it leaves a treatment plant, based on quality. The purpose of this Public Health Grading is to compare water supplies and identify those which may not be delivering quality water. As of mid-2017, only those supplies with populations over 500 were graded.
Leaking cylinder reports
Much has been reported in the media about hot water cylinders leaking since the introduction of chlorine to the Hawke’s Bay water supply following the water contamination event. However, according to a report in The NZ Herald in February, this is probably down to a lack of regular cylinder maintenance by homeowners. One local plumber said most cases he’d seen were actually caused by the chlorine cleaning and exposing existing pinhole leaks that had become plugged up by mineral and lime scale over time. Another plumbing firm advised homeowners in the region to check the date of their cylinder and keep an eye out for any moisture around it if the cylinder was more than 10 years old.
“There are a lot of suppliers that have reassessed their risks and decided chlorination is the way to go.”
Is there any reason why some areas aren’t chlorinating already?
“The drinking water standard has allowed for them not to chlorinate and that hasn’t been updated for 10-plus years. Some of the thinking that determined a secured bore status in drinking water standards now needs to be reassessed because we’ve realised the thinking was flawed.”
Is chlorination a no-brainer, given the cost? “It is... of all the barriers of protection to put in it’s the most cost-effective and easiest, too. So there’s a lot less capital investment for that than for some of the other forms of treatment.” ■ Thanks to Noel Roberts at Water New Zealand for this article, which first appeared in stuff.co.nz

In the office
Andrea Lovell explains the meaning of an ‘almost plumber’ —and why they’re worth their weight in gold. Office staff are what our company call our ‘almost plumbers’. They usually know more about what is going on than the plumbers themselves. They are far more organised, and their technical knowledge is extremely impressive. So, why is it that builders don’t want to talk to them, suppliers forget how important they are, and customers overlook them? Office staff are generally female and these people want to talk to a man—a plumber or the owner of the business (who they always assume is a man). It took some of our builders a couple of years before they were willing to talk things over with me, even after telling them several times that I owned the business too. Just to get them to talk to me, I had to start telling people that [my husband and co-owner] Dale was away or had pulled back from the day-to-day running of the business. I still have the odd new QS telling me they need to talk to someone who knows what they are doing—and they soon get to know that I am the real boss!
So that’s me sorted, but how about the other almost plumbers in our company who don’t own it? Our Office Manager does as-builts, manuals, runs our maintenance plumbers and, as mentioned above, her knowledge is impressive. Yet builders still ask our Contracts Manager for as-builts, even though they’ve been told 100 times our that our Office Manager deals with them—and she still gets male customers asking to talk to a plumber about a job, as they don’t think she will understand what they are talking about. This all seems very old-fashioned to me. Are we not living in the 21st century, and are women not as capable as men? Remember how important the office staff in your company are and make sure you appreciate them, because sometimes your customers don’t. And if your office manager is your wife, give her diamonds— she deserves it.

The Ultimate Reno—coming soon!
Master Plumbers are Programme Partners for a brand-new TV series, due to air next month. Alice and Caleb Pearson, winners of The Block NZ in 2013, are to host a new TV series called The Ultimate Reno. The eight-episode series will follow the popular husband and wife duo as they renovate a 1960s home in the Auckland suburb of Glendowie. The storyline takes many twists and turns, as the pair constantly have to change their plans on encountering a new set of problems. The downstairs area becomes a particular nightmare on the discovery of unsupported concrete block walls and a sewage pipeline running directly beneath the house.

Subbies not to blame
Subcontractors are not the cause of Fletcher Building’s woes, says STCF. With Fletcher Building announcing it won’t be bidding for vertical construction work after completing its current contracts, the industry is left wondering who will fill the gap for work of this kind. The decision came in the wake of ongoing financial troubles for the company. Sir Ralph Norris resigned as chairman of Fletcher Building in February, saying someone needed to take accountability. On the same day, Specialist Trade Contractors Federation (STCF) President Graham Burke put out a media release, strongly refuting the claim that subcontractors had contributed to Fletcher Building’s budget overruns by pushing prices up.
“Throughout Fletcher’s mounting difficulties, there has been an underlying inference that subcontractors are part of the problem,” he said. “The main contractor is in the position to negotiate contracts with subcontractors and they are in the position to bargain with the principal. They hold all the cards and they cannot blame subcontractors for internal mismanagement. “It is not realistic for a main contractor to negotiate a contract with a subcontractor who gives a fixed term quote, and then come back over a year later and still expect that price.” Master Plumbers is among the members of STCF, which represents the majority of subcontractors in New Zealand.

A further amendment is also in the pipeline—this time looking to make breach of the anti-cartel conduct rules a criminal offence. The new rules apply to all industries, including plumbers. As before, the cartel conduct provisions apply where businesses are in competition with each other. Generally, all plumbing businesses are in competition with each other in the local or regional areas that they operate in. Under the new legislation, cartel conduct covers arrangements between competitors that fix prices, restrict output, or allocate markets between competitors. Cartel conduct doesn’t require high level secret meetings where a room full of cigar smokers agree to fix petrol prices. All it requires is an understanding between two or more competitors that they will reduce competition for their benefit. An understanding can come about in conversations, texts, or even through an unspoken understanding. For industries like the plumbing industry, the risks of price fixing are always present. The three things to watch out for to ensure you are not falling into the trap of cartel conduct are:
Price fixing
This is what cartels are notorious for—getting together and agreeing to set the price for goods and services. If two or more 58
April/May 2018
plumbers who compete with each other for customers agree to set their hourly rates or agree that every job has to cost at least $200, an illegal cartel has been formed. Agreeing on a discount is also a form of illegal price-setting. One infamous price fixing cartel was the Heineken cartel, discovered in 2007 by the European Commission. That cartel involved an illegal agreement between the Heineken, Grolsch, and Bavaria beer companies to fix their prices in the Netherlands. The cartel was uncovered when handwritten meeting notes from the three beer barons came into the regulators’ possession. The handwritten notes showed secret meetings at a number of conferences attended by the beer companies, where they agreed to set the price for their beer in the Netherlands. The notes were written in code to avoid detection. The three companies were fined a total of €219.3 million.
Restricting output
Restricting output is new to cartel law, only being included in last year’s amendments to the Commerce Act. Restricting output means agreeing to limit the goods or services available to customers. Usually this is done to drive up prices due to increased demand. For plumbers, examples of how this could come about are if there was an agreement to respond only to one in every two emergency call outs, or an agreement that only a few plumbers could work after 5pm.
SMART BUSINESS Restricting output also covers bid rigging—that is, agreeing to enter inflated bids in a tender process to make other bids look better and ensure work is directed to that person or company.
Allocating markets
This is a particularly important issue to be aware of. An agreement that some plumbers will not offer services in certain geographical areas to allow others to operate without competition will breach the Commerce Act. Under the changes, it no longer matters if the majority of competitors were in on the agreement or not. It only requires two competitors to fall into the cartel provisions.

Practical tips
Every plumber and every member of Master Plumbers needs to remember they are competitors for plumbing services. So what can you do to ensure you don’t breach the cartel provisions? • Do not agree on or even discuss your hourly rates or other aspects of charges with other plumbers. Whilst discussing rates or charges does not directly breach the Commerce Act, it could lead to plumbers entering into illegal contracts or understandings. The Commerce Commission could also interpret the discussions as having that effect. • For Association/Branch meetings, there should be regular reminders from the chair, perhaps at the beginning of the meeting, that those present should not discuss prices, discounts or any other matters relating to pricing. They also should not discuss nor come to any agreement that might substantially lessen competition—for example, in relation to supply arrangements.

If pricing discussions occur during an Association or Branch meeting, members should raise an objection straight away, leave the meeting if the discussion continues and write a letter disassociating themselves from the pricing discussion immediately afterwards. Review your business documentation, policies and procedures for compliance with the Commerce Act. Review your business publications, including websites and newsletters, for compliance with the Commerce Act. Take care when gathering or exchanging information. Consider whether to seek an authorisation under section 58 of the Commerce Act for any agreements that may lessen competition but for which public benefits may outweigh competitive detriments. Seek external legal advice promptly whenever potential competition issues arise. ■

Stopping cybercrime WITH BUSINESS DEPENDENCE on technology at an all-time high, it’s hardly surprising some see this as an opportunity to commit cybercrimes for financial gain or notoriety. Figures from the NZ National Cyber Security Centre show attacks increased by 78 percent in the years 2015-2016. Microsoft reports that 200,000+ NZ businesses have been targeted, yet only half of NZ businesses are prepared for these kinds of cyber-attacks. As IT systems and software have improved, so have the attack methods. The days of common viruses that damaged data, or hackers that just wanted to snoop around, have been replaced with ransomware—applications that render data unusable until a fee is paid—and malware that infects computers with advertising and popups. Cyber security companies are fighting a constant battle, and many antivirus software products boast a 90 percent or above blocking rating. However, security is only as good as the user, just as a lock on a door is pointless if the door is left open.
Common security threats The most common form of cyber threat users experience is phishing. Phishing is an attempt to gain information to exploit the victim. Most phishing attempts are via email seemingly coming from the organisation’s manager. The email usually takes the form of a request to transfer money or give financial details, and is 60

One of the biggest threats to your business is encryption malware, as technology specialists ITroom explain.
often sent to the company accounts staff. Another method is sending a link to a document that requires login via email, Dropbox, or any of the other common accounts people possess. Your best defence against these is common sense. Emails requesting details that are out of context, or are unusual in tone should be checked by a quick phone call. The likelihood of a document download allowing authentication via multiple methods—eg, Microsoft, Facebook, Google or Dropbox accounts—is unlikely and should throw up a red flag. Ransomware is one of the most crippling methods of cyber-attack for a business. This often takes the form of a popup suggesting you install an antivirus for system security, or a similar popup telling you to install a driver to make the computer work properly. Once the ransomware takes hold of a machine it begins encrypting files, and if the computer is on a network it spreads encrypting over network shares and leaves copies of itself for unsuspecting users to execute. The files are rendered unusable unless a payment is made.
Protecting your data The best protection is a comprehensive backup strategy. ITroom take client data backups several times a day and replicate them offsite so your data is always safe. We can also arrange Security Awareness Training, which can test your
staff behaviour around common attack methods and provide reports on your weaknesses. Additional ways to protect your data are to: • Ensure every computer has an antivirus application and this is kept up to date. As a bare minimum, the free Windows Defender should be used, but applications like Webroot or Eset Nod32 are considered some of the best in the business. • Enforce strong password policies, and don’t use the same password across all your applications and services. • Keep your software up to date— most companies release updates that contain security patches on a semi regular basis. • Run a regular malware/spyware scan. Malwarebytes offer a couple of excellent free scanners. o https://www.malwarebytes. com/mwb-download/ o https://toolslib.net/ downloads/viewdownload/1adwcleaner/ Finally, there’s no beating common sense. Don’t be hasty to click on attachments or popups, check reply addresses to see if they are actually the person they purport to be, and pick up the phone if an email seems out of order. ■ For more information or to discover how we can help, call ITroom Ltd on 0800 10 10 95.

Employment law changes WHEN OUR COALITION Government was sworn in late last year, it brought with it an expectation that some changes were afoot for our employment law. We’ve since seen a number of announcements relating to changes in a range of areas of our employment landscape, and for small business employers, already busy juggling their ‘day job’ with the responsibilities of business ownership, it can be hard to get a steer on what the changes are, and which apply to their specific situation.
employment law recently, however, has been the scrapping of 90-day trial periods. While this is on the horizon for larger businesses, the Labourled Government’s Employment Relations Amendment Bill will allow small businesses (with fewer than 20 employees) to continue using 90-day trials, in an effort to keep their barriers to hiring low.
Increase in minimum wage
Also among the Bill’s modifications relating to the rights of employees is that reinstatement will be restored as a primary remedy to unjustified dismissal. Given many small businesses operate almost like families, the ramifications of a reinstatement following what’s deemed an unjustified dismissal can potentially be highly challenging and complex. The handling of employment disputes is an area where many small business owners express unease, and changes like these are a timely reminder to smaller employers that they need to adequately educate themselves on how correctly to handle these types of situations. There’s no doubt that’s a challenge. Keeping up with ongoing legislative changes and increasing compliance demands (such as those brought about with recent health and safety reforms)
One of the biggest changes potentially affecting small businesses is an increase in the minimum wage. From 1 April, this rose by 75 cents to $16.50 per hour, with further increases leading towards a targeted $20 by April 2021. For many employers, the cost pressures associated with these increases will be a hot topic.
Paid parental leave
We’re also on the cusp of changes to paid parental leave, which will increase from 18 to 22 weeks from this July, again with further increases leading towards a targeted 26 weeks of paid parental leave from 1 July 2020.

puts greater cost and time pressures on small business owners who, as we’ve mentioned, are often already stretched. And without a raft of specialist support staff around them-such as the HR practitioners you’d typically have in larger firms-small business employers can find themselves in situations where they simply don’t know what they don’t know.
Protect yourself
Building trusted relationships with good advisors, therefore, is key to staying on top of legislative changes and your obligations as an employer. Outsourcing certain aspects of your employment requirements to external specialists can also be helpful, or investigating the growing range of software tools that can specifically help small businesses manage their compliance and HR needs. ■ This is solely for information purposes (and is only for New Zealand residents).

Goodbye guesswork The Inland Revenue takes aim at provisional tax. PROVISIONAL TAX IS being made a whole lot easier for small businesses. Inland Revenue is urging businesses with annual turnover under $5 million to talk with their accounting software provider or tax agent about a new option that allows them to pay provisional tax only when they are making a profit. The Accounting Income Method, or AIM, makes managing cash flows simpler because provisional tax payments are based on the business’s actual results. Inland Revenue’s Deputy Commissioner for Transformation, Greg James, says IR has created a product that takes the guesswork out of provisional tax payments. “At the moment, businesses often have to take a stab in the dark about their projected earnings for the current year,” he says. “When that’s off the mark, it can lead either to an overpayment of tax and a long wait for a refund, or an underpayment and a subsequent penalty charge. “The beauty of AIM is that your tax payments are in line with your business cycles and if you go into loss you can collect your refund of overpaid provisional tax immediately.”
A series of webinars are being hosted to talk through the benefits for small businesses and explain how it all works. Three accounting software providers will be offering AIM as part of their package: MYOB, Reckon and Xero. “You don’t have to be a tax genius to make the calculation,” Greg James says. “The accounting software does all the work. “We think this could make life easier for tens of thousands of small businesses but now is the time to check if it suits your circumstances. We suggest you talk it over with your tax professional or software provider.” The new rules introducing AIM took effect from 1 April 2018 and apply from the 2018-19 and later income years.

Eye on the overheads THERE ARE EIGHT main issues that cause cash flow problems in a company: 1. a corporate lifestyle beyond the ability of the company to finance 2. not enough sales 3. slow invoicing 4. bad collection practices 5. leakage (ie, stock and other items walking out the door or not being charged) 6. incorrect pricing (ie, insufficient margins) 7. inefficient staff 8. a lack of hours being charged each day. Every one of those factors can cause a business to have cash flow problems or even cause the company to fail. Here, we’ll look at company lifestyles, because plenty of companies cannot afford theirs. It is always good to see tradespeople succeeding in their chosen field and one of the signs of their success is the vehicle they drive. Leasing is a good way for tradespeople to have a nice vehicle while keeping their capital to finance their business, and I believe that most business advisors would agree. However company lifestyles can become a burden on the revenue stream, if for instance that vehicle is too expensive to lease or too expensive to run. If you look at your last year’s accounts, you will see what you spent to keep the doors open. You should review all those costs and you may be very surprised just how much you can save by being frugal. There are lots of suppliers keen to do business with you, and you should not hesitate to ask for a quote for all of those expenses. Include in that power, phone,

Reducing costs is just as important as increasing sales. It is easy to establish how much overhead it costs each hour you are open for business by simple maths—a figure, I might add, that surprises a lot of people. If you have taken a strong stance in getting those overheads down, then you should see an improvement in your profitability and cash flow immediately. It is not OK to say the overhead is what it is; it is what you make it. ■

In the last edition, I made the point that business people should ensure their business is making a healthy profit to give them the money they need to live well, rather than relying on a Lotto win. These comments did not sit comfortably with one reader, who called to say money was not his god and he would continue helping people by doing work at less than market rates. Many business people fear that a better lifestyle can only happen at the expense of others and by compromising their values. Some struggle with what they perceive as a choice to do good or to make a profit. Everyone’s goal should be to succeed, and if you choose to get into business, making a profit will be one measure of success. I am not suggesting you amass so much money as to ruin your life, but rather not to let insufficient money ruin your life. Believing in your own worth is a great place to start.

Health & wellbeing People work better when they feel good, says HR specialist Lisa Duston. HEALTH AND WELLBEING is an important factor in today’s NZ workplaces. Those promoting health and wellbeing have better engagement from their people, reduced absenteeism and higher productivity—and their people enjoy improved wellbeing and higher job satisfaction. Why aren’t more businesses encouraging this, I say! When it comes to health and safety at work, there should be as much emphasis on health as there is on safety. Employee wellness has a huge impact on a business, with significant productivity losses when employees are off sick or back at work before they are fully recovered. According to a 2017 Wellness in the Workplace survey by Business New Zealand and Southern Cross, New Zealand lost nearly 6.6 million working days to absence in 2016. One employee absence can cost the employer $600-$1,000 a year. How employees feel in the workplace has a major impact on their general wellbeing. Employees want (and need) to feel good at work—they spend too many hours there not to—and this comes down to a business doing its bit for its people. Improving health and wellbeing in your workplace doesn’t need to be complicated. A few ideas include:
•
Work flexibility – Allow for some flexibility for employees to enjoy a better work/life balance • Support employees who are unwell – Ensure they take the time needed to recover • Wellbeing activities – Allow time to do something fun as a team • Ask your people – What they would like? • Time with the team – Morning tea shouts or team lunches • Celebrate successes – Acknowledge individual and business achievements. With a little bit of time and some creative thinking, you can make a big difference to the health and wellbeing of your people, which in turn helps your business. Give me a call if you’d like to discuss or brainstorm some ideas. ■ About the author: Lisa Duston is HR Manager at Master Plumbers.

Measuring productivity DEMAND FOR CONSTRUCTION related occupations will increase by 11 per cent between 2016 and 2022, according to 2017 Government projections. The demand for plumbers is expected to grow by 15 per cent—rising 32 per cent in Auckland. Meanwhile, economists have been discussing OECD findings on low levels of productivity in New Zealand. Suggestions for improvement include upskilling the workforce, increasing business investment and improving management. The gas, plumbing and drainlaying sector focuses strongly on licences and qualifications—so how do well-certified trade businesses make productivity gains? Through investment in technology to manage and streamline job processes, and by measuring performance with a range of metrics. Teletrac Navman’s 2017 Telematics Benchmark Report found that reducing operational cost is the top business goal across all sectors with fleet vehicles in New Zealand. 46 per cent of Kiwi organisations with telematics, reported seeing a measurably positive effect on their fuel expenditure, and 23 per cent lowered their rate of vehicle accidents. Congestion is the most challenging issue faced by fleets, with 62 per cent identifying this problem. For tradespeople with several jobs lined up per day, telematics 66

may provide some relief, through real-time rerouting to avoid choke points and bottlenecks. Businesses with telematics monitor distance driven (56 per cent), proof of service (46 per cent), hours of service (46 per cent), and maintenance (37 per cent)—these four metrics are hugely valuable to trade fleets looking to boost productivity. Here are five productivity tips for using GPS fleet management technology: 1. Integrate fleet management software with job management and invoicing software for fast and accurate back office processing 2. Use alerts to run effective distance-based maintenance to address wear and tear 3. Allocate closest staff to the job sites—especially for urgent jobs 4. Quickly answer customer enquiries on expected travel times from the main office 5. Monitor and improve driver behaviour to reduce excessive fuel use on speeding, harsh braking and overacceleration. ■ About the author: Ian Daniel is Vice President and Managing Director of Teletrac Navman, Asia Pacific.
Better Business Growth
The Skills Organisation is launching a new service to assist plumbing and electrical businesses.
SKILLS HAVE ENGAGED the services of the former CEO of Master Electricians, Neville Simpson, to deliver a network of experienced trade specific advisors to increase business capability of SMEs across the Specialist Trades represented by The Skills Organisation—in particular plumbing and electrical. Using industry stakeholders to identify SMEs that are either start-ups, growing or in need of assistance, Skills will make experienced advisors available for one-on-one advice and assistance under the Better Business Growth project. The trade advisors will speak the lingo, ‘been there done that’ and have a passion to see SMEs and the industry grow. The service will initially be free for participants—but the business owner will ultimately be expected to pay for it. Stakeholders are being consulted as to how they might support the project as it develops and grows. Neville has already received strong support for this project from industry wholesalers, suppliers and trade associations, as well as many existing business owners.
A first successful pilot will soon be followed by a second to solidify the process. The Better Business Growth service will then be available on a national basis. Key objectives 1. Establish why the owner has gone into business 2. Review their goals and aspirations 3. Introduce structure, process and planning and seek to remove the haphazard development that affects many SMEs 4. Introduce business and financial literacy skills throughout 5. Encourage succession planning 6. Build a business that will lead not only to productivity gains but also increased employment opportunities 7. Get the owner working on rather than in the business 8. Give the owner some time back. Anyone wanting further detail should get in contact with Neville on 0274 801235 or nevilles@skills.org.nz ■

SAFETY FIRST
Site traffic safety A recent Worksafe prosecution highlights the need to have traffic management systems in place on all worksites— especially when using an excavator. A LARGE DRAINAGE contractor was fined nearly $50,000 in 2017, and had already agreed to pay $50,000 in reparations at an earlier hearing, after an employee was run over by an excavator. Since the incident, the company has undertaken to retrain the man to enable him back into full employment within the business, and has made some significant, positive changes, “but it should not have taken a life-changing incident to spur the company to change,” said WorkSafe Chief Inspector Keith Stewart following the investigation. “Some very simple changes on the day would mean that the employee would have the full use of his legs today. Following industry guidelines would have removed the need for anyone to work close to the machine.” The WorkSafe investigation found that the company failed to carry out an adequate hazard and risk assessment for the task and did not identify appropriate control measures and communication systems, exclusion zones and a spotter. Traffic management is one area WorkSafe is increasingly looking at when they come onto site, as there has been an increase in the number of accidents relating to vehicle/person contact.
Where excavations are involved, if a thorough risk assessment has been undertaken and a good safe work procedure is followed, there should never be an incident involving an excavator striking a person.
Considering all the risks The Health and Safety at Work Act 2015 requires you to look at all the associated risks involved with a task or hazard, especially where you have created the hazard in the first place (eg, bringing the digger onto site, creating the trench etc). Some of the risks associated with using an excavator for trenching are: • Stability of existing soil • Competency level of operator • Swing arm radius of the arm and attachment • Existing underground services • People in vicinity • Weather (eg, rain) • Digger operator blind spots • Faulty equipment • Hitch pin attachment • Mechanical faults > April/May 2018 69

Structural faults Proximity to other hazards Location of spotter Competency of spotter Communication system Loading excavator Unloading excavator Width of trench required Failing to wear PPE Passengers on excavator. Once the risks have been identified, you must come up with effective controls to eliminate the risk or, at the very least, minimise the risk. Whichever form of risk register you decide to use must be specific to your business, not just one downloaded from the internet as the documented controls will be the controls that you are held accountable for. If a risk has the potential to cause a fatality, it is good practice to develop a Safe Work Procedure (SWP) to cover the task. I prefer Safe Work Procedure rather than Standard Operating Procedure, because every site is different, so the work being undertaken is never ‘standard’— which could lead workers into treating all sites as the same, regardless of differing risks. A good place to start looking for information to assist with developing a SWP is Worksafe’s Excavation Safety Good Practice Guideline (July 2016). It does take some time to develop controls against identified hazards or risks and to ensure that the workers involved in the task have been suitably trained and are competent. However, not going through this process can more detrimental to the business through lost time injuries, damage to plant and equipment and, in the worst-case scenario, through lengthy and expensive court proceedings. This can be used as part of a checklist to ensure that you have covered everything off in a quote or tender document (ie, extra unexpected costs may be incurred through failing to identify the need for cable location, site fencing, hiring a bigger excavator, extra workers for traffic management or spotters etc). If you had already developed your risk register then none of these ‘extras’ would impact your profit margin and your professionalism wouldn’t be called into question if you had to try and recover these costs through ‘extras to quote’. This particular case was under the old legislation. Had it been under the new legislation with the increased levels of fines, I believe that the firm involved may have been looking at almost double the court fine, which has to be paid by the business as it is not covered under any indemnity Insurance policy. ■ Find the Excavation Safety Good Practice Guideline at http:// construction.worksafe.govt.nz/assets/guides/WSNZ-ExcavationSafety-GPG.pdf About the author: Richard Tattersfield has over 17 years experience in health and safety.

Trenching with an excavator
Below is an example Safe Work Procedure (SWP) for trenching with an excavator. When using an excavator to create a trench or back fill a trench, the following procedure should be followed. If this procedure does not cover identified risks or hazards on site, then a Job Specific Safety Analysis must be completed and approved by management prior to starting work. This SWP is not intended to replace the Excavation SWP but is intended to be used alongside it when an excavator is used. 1.
We will ensure that a check has been completed with the main contractor to ensure that there are no underground services in the area to be excavated. Where this information can be provided or confirmed, we will contract out the task to a competent, approved contractor. 2. All workers involved with the work will attend a pre-start meeting to go over all aspects of the job, the equipment being used and the risks that are expected on site and the recommended controls to mitigate the risks. 3. On the day of commencement of work, the pre-start plan will be reviewed against the physical site to ensure that nothing has changed and the risks and controls put in place are sufficient to prevent any harm or damage from occurring. 4. The excavator operator will inform the site supervisor and update any site hazard board to include the excavator and excavation. 5. The site must be secured against any unauthorised access by means of temporary 1.8m fencing (this may vary depending on the location of the site, the number of people in the vicinity and the depth of the trench). 6. We will ensure that the size of the excavator is sufficient for the task at hand, for the area where the trench will be located and capable of lifting a trenching shield in and out of the trench (if applicable). 7. Ground conditions will be monitored daily to ensure that the trench is stable and safe to operate in. Heavy or prolonged showers of rain, and previously unknown excavations can quickly change the ground conditions from safe to unstable. 8. The excavator operator is in control of the workplace while the excavator is being used. Everyone involved in the work must follow the operator’s directions. 9. We will only use competent, trained spotters when required to assist the excavator operator. We will not use anyone else who has not been signed off as competent under our competency register. 10. At the end of the day, the excavator will be parked up, locked and the keys removed from the ignition.

MASTERLINK MESSAGEBOARD
Value proposition Why taking on a high-quality apprentice through Masterlink makes financial sense. PLUMBING FIRMS WANTING to take on apprentices often have queries for our Regional Managers around the cost benefits of going through Masterlink. Below, we provide answers to some of the most commonly asked questions. Q1: Masterlink charges the host business a weekly fee by direct debit—what is this made up of? A: Most of the fee covers the apprentice’s weekly wage. We handle the calculation and payment of the apprentice’s wages, including tax, ACC levy and KiwiSaver deductions, which saves your business admin time and money. The fee also covers our day-to-day management of the apprenticeship—see Masterlink Services below. Q2: How do I ensure I make a profit from the apprentice? A: You set the amount you want to pay your apprentice and Masterlink calculates your fee accordingly—based on a 40-hour working week. You only pay for the hours your apprentice actually works for you (approx. 40 weeks a year). We continue to pay the apprentice when they’re on annual and sick leave, statutory holidays and block courses, but you aren’t charged for this. As long as you add a percentage mark up when you set your apprentice charge out rates, you will make a profit. Q3: Are there any other cost benefits in choosing Masterlink over going direct? A: There are a number of tangible costs not passed on to the host business. They include: • • • • •
• •
Candidate advertising and recruitment Pre-employment drug test, medical check, plus inoculations if needed Driving history check and ongoing licence status monitoring Starter tool kit and protective clothing, plus annual PPE allowance Training fees paid (if the apprentice is eligible for the government’s 2-year fees-free training, we pass on the savings by reducing their sign-up fee and supplying them with extra tools) Accommodation, travel and meal allowances while on block course (if required) First Aid & Site Safe certificates plus refreshers.
Q4: How do I get value from the apprentice? A: If your apprentice is doing a tradesperson’s work on a job, he 72
April/May 2018
or she should be charged out as such. Some companies say they can’t charge a customer for a firstyear apprentice who’s standing around watching. The answer is to give the apprentice basic tasks the qualified tradesperson would otherwise have to do. This frees up the tradesperson to focus on the more complex, restricted work—and potentially get it done in less time. For example, if the apprentice runs back and forth to the van collecting parts and tools, or digs a trench, or prepares for a pipe-out, you’re making good use of them. Sometimes, two people are needed on a job for health and safety reasons, so it makes good sense to send your apprentice. For more information, get in touch with one of our Regional Managers (details at www.masterlink.co.nz).

Helping hand
Masterlink apprentice Gavin Wilding attended Camp Quality, which helps bring some fun into the lives of young people living with cancer. GAVIN WILDING, WHO works at Mana Plumbing in Porirua, first heard about Camp Quality through his flatmate, who’s a teacher. She had volunteered as a Companion for the past four years, and thought Gavin would enjoy giving it a go. “I thought it sounded like a good thing to do, so I signed up,” he says—and Masterlink and Mana Plumbing got right behind him. A volunteer organisation, Camp Quality was established in Auckland in 1985, and now provides camps in five regions around NZ for children aged five to 16 affected by cancer. It’s all about providing a fun, stress-free environment where the young Campers can ‘just be kids’ for the week. Gavin headed to a New Plymouth boarding school for a week in January to join the camp as a one-on-one Companion to a young boy whose sister had passed away from cancer. “There were about 50 kids on the camp, and all sorts of activities, like water sports at the beach and card games and basketball at the school,” says Gavin. “There was also time to just hang out, chill and be there for support.” He and his young companion also loved the food on offer, with awesome breakfasts, morning and afternoon teas, lunches, dinners and desserts laid on each day by willing volunteers. “I’d do it again for sure,” says Gavin. “It’s really rewarding to help out.” Find out more about Camp Quality at www.campquality.org.nz Above: Gavin with his young Camper.

Vive LeVivi!
Kitchen game-changer
The elegant LeVivi range is easy to install and easy on the wallet.
Where form meets function—a kettle and mixer-tap combined.
As your ‘Team in Black’, Plumbing World was proud to showcase a selection of its newest exclusive products at the Master Plumbers Conference 2018. The LeVivi Marbella toilet suite and freestanding bath make an elegant pairing that are easy to install and easy on the wallet. Match this with the new LeVivi Bath Tray and your customers will be well on their way to creating the perfect bathroom retreat. If your customer needs a vanity to fit a small space, then check out the new LeVivi Surrey Slim vanity. With a 350mm depth off the wall, it is ideal for apartments, ensuites or small bathrooms. Combine this with the stunning Paini Nove basin mixer for the perfect ensemble. Finally, Plumbing World is proud to promote the Toto Alicante Comfort Height Suite with its contemporary pan design. This design is proving popular in the market and sure to turn heads.
InSinkErator®, the company synonymous with kitchen innovation has done it again with the amazing Multitap… a kettle and mixer-tap in one! MultitapTM provides instantaneous filtered near-boiling water for effortless coffees and teas, as well as filtered hot and cold water from the same tap. This is the combined solution that will change the way homeowners enjoy their kitchens and entertain guests. Now there’s no need for jugs and kettles cluttering up the kitchen. With near-boiling water ontap, a host of kitchen tasks are quicker and easier… like speeding up prep time for vegetable and pasta dishes and tackling the toughest wash-up tasks with instantly available steaming hot water. MultitapTM is a game-changer in the kitchen and incredibly easy to install. Plug-in convenience and tool-free connections make it simple to fit, and the compact water tank (about the size of a toaster) tucks neatly out of sight under any bench. With three Italian-designed and manufactured tap styles to choose from and a 5-year warranty, this is the must-have kitchen improvement of 2018.
Infinity and beyond Rinnai have recently added the new INFINITY® A Series to their range. The INFINITY® A Series has the same great performance and reliability you’ve come to expect from a Rinnai INFINITY®, with some new features for quicker, more convenient installation and service. Reduced commissioning checks and a lighter appliance help to reduce installation time, and make the install easier. Service time will be significantly reduced as the internal design of the A Series means better access to all major components. Rinnai have also kept the important things the same. All connections are in the same location as the INFINITY® VT, so replacing these older models will require little to no pipework. Also all INFINITY® VT accessories are compatible with the A Series, and the A Series has the same great efficiency with models carrying a 6 star energy rating. For more information, visit rinnai.co.nz or phone 0800 RINNAI.

You couldn’t make it up… media oddities of the plumbing kind. The way of the future
Thanks to Craig Foley, Director of Foley Plumbers, for sending in this photo of a toilet door sign, showing the shape of things to come.
Plane loo problems—experts on hand
According to a Newshub report in January, a flight packed full of plumbers en route from Norway to Germany was forced to make a U-turn after the plane toilet suffered a plumbing issue. About 85 plumbers from a Norwegian plumbing company were on the flight, travelling to Munich for work, notes the report. They were apparently keen to sort the problem themselves but were told it wasn’t possible as the work was external—and the company’s chief exec wasn’t keen to send a plumber to work at 10,000m!
Museum of parasites
Japanese doctor Satoru Kamegai set up a museum of parasites in Tokyo in 1953 to educate citizens at a time when intestinal worms and other parasites were rampant in Japan, reports The NZ Herald. Since then hygiene has improved significantly—but the museum remains a hit. According to the paper, more than 60,000 specimens are housed in the six-storey building, with the second floor dedicated to parasites that have a relationship with the human body. Exhibits here include an 8.8m long tapeworm that went unnoticed by its host human.
How-to: making a freedom camper ‘poo tube’
With reports of freedom campers using the NZ countryside as a ‘giant toilet’, DOC is giving advice to those finding themselves caught short without a public toilet, reported Newshub in February. This involves getting a large diameter PVC pipe and ends from a plumbing or hardware shop, attaching screw caps to each end, gluing one end shut and taping on some webbing for easy carrying. “Your tube will be durable and reusable,” says DoC.

Dogs are a utility’s best friend
Water utilities are increasingly recruiting dogs to detect leakage, reported WaterWorld TV in March. In the UK, 16-month-old cocker spaniel Snipe is being used by United Utilities to sniff out the tiniest traces of chlorine used to disinfect water supplies, while Hector the Fatberg Detector is being trained by Southern Water to sniff out fats, oil and grease. Australia’s Water Corporation has also been training dogs to smell water when there is a potential break along underground mains, according to WaterWorld. Spaniels Tommy and Emma could find leaks where other detection methods are unsuitable or human access is difficult.
Buy your Poopeez in store now
Apparently, Poopeez ‘exploding toilet toys’ arrived in US retailers this January. Kids open the box to find a list of Poopeez characters—including Skidmark, The Log and Little Squirt— two T-shirts with a “Yes, I have Poop on my shirt” slogan, stickers, a coffee mug sized ceramic toilet, a Portaputty multi pack and several plastic toilet paper rolls containing surprise Poopeez. The fun doesn’t end there. The box also contains a toilet launcher to shoot the toys from the toilet. Those with total faecal fascination might also like to purchase Flush Force, a “foul new line of mutated, collectible figures” from the bowels of the sewer.
When your name matches your job
NZ Herald’s Sideswipe columnist recently took a look at some examples of when a person’s name matched their job. These included a school woodwork teacher with a wooden leg by the name of Mr Forest and a 1970s council official in charge of rubbish collection by the name of JH Smellie. She went on to mention a friend called WC Drain (yes, really) who ran a large plumbing company in Australia, and a UK plumbing firm by the name of Allcock and Tinball…
Setting the rules for bathroom etiquette
An Australian plumber got so fed up with his wife using his razor, stealing his hair products and leaving wet towels on the bathroom floor that he stuck a long and funny letter outlining his grievances to the bathroom mirror, according to The NZ Herald. The newspaper reports that his list of habits that must be changed or stopped also included never putting the lid back on the toothpaste, not emptying the bathroom bin and forgetting to flush the toilet. Fair point.

Everything dodgy… including the kitchen sink.
No restraints
“Here’s a photo of a 300L mains pressure hwc located in the ceiling space above a toilet area that I saw on a recent trip to Blenheim,” says Dale Lovell of Heron Plumbing. “We all know that it’s a bit shaky in the South Island, so you would assume that the seismic restraints would be an important part of the hwc installation. With the weight of the water and the hwc, there is near on 400kg basically unrestrained.”
Say, what?
“We don’t even have words for this…” says Jodi Lawrence of EC Shaw Plumbers, who sent this photo.
Round the traps
Thanks to Thomas Wilson of Go with the Flow for sending in this photo. “Customer called saying the kitchen takes a while to drain….”
Bit off-colour Power crazy
This electrifying photo was sent in by Shannon Langford at Mico. “Gasfitter came to rectify and was shocked with what he found!!”
“We recently found this under a sink on a job in an apartment building,” says Mike Gooch of EG Glennie. “You can see the discolouration on the hot outlet pipe from the heat! “Push-fit pipes are so easy—even a handyman can do plumbing… NOT!!”
Fast and loose
“Found this on my travels in Castlepoint,” says Vinnie van der Linde at Watermart. “LPG installation with no isolation valve or test point and 9kg gas bottle sitting on a step ladder not even chained up!”
