CHAIR’S MESSAGE
EDITORIAL: 214-349-5965
NICOLE DUVALL, MBA, Publisher,
n this page, you will see a picture of myself from back in 1990 when we had just celebrated our ninth year as an association. Hard to believe I look exactly the same today as I did back then (just kidding), but what I have lost since then I have made up in years of experience and wisdom. I hope. What struck me about the early days of our group was the energy and vision that each of our Directors brought to our organization. If you were on the Board back then, everything was your responsibility. If you suggested a project, well, it was your duty to carry it out. For those of you who run your own small business, I am sure you know that feeling well. But we were all united by the same vision that we have today: each of us becomes better at what we do because we are always seeking out opportunities for top-notch training and education. Today, I am glad to report that our organization has grown because of the dedicated staff we have hired who carry out our Board’s mission each day. Their dedication to each of you and your development knows no bounds. It is a self-fulfilling cycle: a talented staff creates a stellar experience for members; therefore, more members join, stay, and tell more people about the experience. I want to thank all of you for taking the time to be a member of this organization and to recognize your dedication to improving yourself through our training. What I have also noticed over the years is how much our industry has changed: I have watched manufacturers and firms consolidate into larger entities. More people are trying to enter our industry, and some feel as though they can become contractors on Day 1. I do not want to tamp down anyone’s enthusiasm, but it is often said that it takes around 10 years of hard work to become an overnight success. That is why we provide training and education beyond installation and design, but to help people understand the numbers behind their businesses. Too often, people go into business for themselves just to earn daily wages. I hope that if you want to pursue that path that you will take advantage of the educational programs we offer, especially at our annual conventions. I have watched our industry change from a legislative standpoint, too. It used to be that fire suppression systems were not required in many buildings. You can walk into any structure that has been grandfathered into existing codes, look up, and see nothing. Now, it seems as though new residential and commercial units alike all are required to have fire suppression systems. This bodes well for us as an industry, and it is something to keep in mind when construction starts to slow, and you start to worry about when the next job will come. There will always be work, and the people who perform the best will be the ones first in line for it. As much as I want to keep talking about the past of our organization, I want to take this moment to talk about our future. The only way that we will sustain our membership is by getting more young people to enter our trade. It has been hard this past year to get into the schools to talk to students about their future. But my challenge to you is to reach out to the young people you know and talk to them about their future. Show them what they can attain at a fraction of the cost of a college degree. More than that, consider offering internships and apprenticeships to give people an entry point to see what we do each day. Once someone stands back after a day’s work and looks at what they created—a structure that will save lives—they will have that sense of pride that we all take in our work. John Maxwell, the author and leadership expert, said, “Growth inside fuels growth outside.” Our association was founded on the belief that training is what our members need to grow, and it has been the bedrock vision ever since our inception. I hope that you will continue to fuel your internal growth with our training and education so that you grow personally and in your business. It is a privilege to serve you, our members, and may the next 40 years be as successful as our first 40. n TED WILLS AFSA BOARD CHAIR

PRESIDENT’S REPORT
N
ow that we’ve put 2020 in our rearview mirrors, it’s clear that most of us have seen changes, disruptions, and unforeseen problems as we’ve struggled to hold onto the business plans we developed and thought were solid when we left 2019 behind. Can you remember pre-COVID-19, when our markets were strong, the cost of money was cheap, and unemployment was around 3 percent nationally? Who could have imagined how quickly a pandemic would change our lives and businesses so completely? Now that our lives have been forever changed, we have to face the reality that many of the modified behaviors this pandemic ushered in will be with us well into the future—even beyond the point where the virus is in that same rearview mirror. While we enthusiastically welcomed 2021, the reality is that the new normal won’t be normal anytime soon. I recently read an article espousing the thought that virtual engagement is here to stay. While most of us suffer from Zoom fatigue, we agree that online meetings are not going away. As such, we’re positioning AFSA’s events and training programs to accommodate more virtual training and hybrid participation. Now that the world has seen an alternative to actual travel, many people will want the digital option of working and meeting from their home or office. We should expect to see people in our organizations willing to sacrifice some benefits in exchange for the opportunity to work from home, including salary reductions in exchange for time. Virtual meetings save time and cost, but not without sacrificing something in exchange. That something is perhaps the most critical element of our lives and relationships—communication. The return to “normal” is not likely to bring a 100-percent return to the old ways of doing things. Even when it’s considered safe to travel or gather in groups, many people will prefer a partially or entirely virtual event. We see this as likely to be a pervasive theme in the delivery of our training programs, which is why AFSA will be introducing our new virtual classroom for our apprenticeship curriculum this year. This will help deliver the classroom portion of our apprenticeship program for those working in more remote regions, as well as those too busy working to participate in training during the regular workday. Digital networking, social media, and electronic communications, as opposed to in-person or even telephone communications, are more common than ever before, but we sacrifice a lot in terms of communication. How we communicate is an important part of how we resolve problems and conflicts, and these critical issues will suffer without in-person interaction. Communication takes many forms, including visual, auditorily, visceral, and digital. What we say and how we say it, along with our body language and facial expressions, all covey as much of the message as our words do. When we’re on the phone, we lose the visual aspect of communication. When we email, we lose the visible and vocal intonation in our message—leaving only the digital. How we write, punctuate, and the words we capitalize will all be perceived as a part of the message and will impact how others receive and act upon your message. It’s a lot easier to misunderstand a person’s intent with
8 SPRINKLER AGE | MAR/APR 2021
email than in a verbal conversation. It takes more back-and-forth time to clarify what is meant and understood by those who must interpret the message. Even as Zoom-type meetings have become the new normal, messages are truncated, and people wearing masks take away the facial expressions communicating the visual part of the message. Thoughts and ideas are held back in the interest of time and efficiency. Leaders need to make a conscious effort to ensure all voices are heard and ideas are not missed or glossed over. For our association to understand and meet our members’ needs and demands in this digital age, we will need more feedback and interaction to know what your expectations are and how to meet and exceed them. Working remotely and seeing less of each other in person at traditional meetings means we will need to learn to rethink the time it takes to plan events and deliver content in meaningful ways. Being seen and heard, shaking hands, and seeing the understanding in another’s eyes are all missing in the virtual world. We will have to adapt to ensure communication remains positive and strong. These are just circumstances to be dealt with, bumps in the road that should not be seen as detours. Our association is taking the steps necessary to deliver on our mission and continue to be the voice of merit shop fire sprinkler contractors and provide the education and training necessary to help our members grow their businesses. This dynamic shift will change how we deliver content, but it will never deter us from delivering the message of fulfilling our mission. Call us, send us emails, smoke signals, or carrier pigeons—whatever it takes to understand what you want from our staff and what forms our communications should take. We’re excited about the promise we see for 2021 and beyond. As I talk to sprinkler contractors across the country, backlogs and opportunities are still pretty strong, and many of us are still pretty busy. During this 40th anniversary, your AFSA staff is excited to hear from so many members and associates planning to attend AFSA40, September 18-21. The convention committee is working hard to make this a convention to remember and one you won’t want to just hear about. One of the new technical sessions we will be introducing this year will include a number of “Ask the Experts” seminars. These sessions will not have any specific topic or slide decks but, instead, will feature experts from manufacturing, labs, NFPA, and AFSA technical committee representatives ready and willing to field and respond to your questions or concerns related to codes, standards, or product applications. Based on the buzz surrounding this event, we expect to see record numbers of attendees in San Antonio. I hope we can count you in! n

FLASHPOINT
T
he process of creating the 2022 edition of NFPA 13, Standard for the Installation of Sprinkler Systems, is winding down. Public inputs, public comments, technical committee meetings and discussions, and the voting process have been completed. Overall, the AFSA technical services staff is satisfied with the results. However, there is one technical item the team feels needs to be addressed before the 2022 edition is approved for release for use. The purpose of this column is to describe the NFPA process that needs to be followed to challenge this issue and briefly describe the concern with the current language. In the May/June 2021 issue of Sprinkler Age, I will describe the technical issue in detail, explain why we feel this issue needs to be changed, and the process we will need our members to assist. At this point, AFSA’s technical service staff has filed a Notice of Intent to Make a Motion (NITMAM). A NITMAM is a proposed amending motion for NFPA membership consideration and debate at the NFPA Technical Meeting. These motions are attempts to amend the Technical Committee’s recommended text published as the Second Draft. Once filed, the Motions Committee reviews all notices and certifies those deemed proper, in accordance with the NFPA regulations. The Motions Committee can also, in consultation with the submitter of the motion, clarify the intent of each motion and combine motions that are dependent upon one another so that they can be made in one single motion at the NFPA Technical Meeting. The Motions Committee report is published in advance of the NFPA Technical Meeting and contains all Certified Amending Motions (CAMs). Only CAMs and any proper follow-up motions are permitted at the NFPA Technical Meeting. A NITMAM can only be filed by an individual who meets very specific conditions. In this case, I met the required conditions, and we expect the NITMAM to become a CAM. We are aware of at least two other NITMAMs which have been filed on this technical issue. We believe if all of these motions become CAMs, all three will be combined for one single CAM. Since COVID-19 concerns have once again impacted the NFPA annual meeting, the discussions, arguments, and voting on the CAMs will be handled virtually. This process was utilized last year, and while the process was completed, NFPA experienced and learned from some issues with the process. At the time of the writing of this column, NFPA has not released the exact process which will be followed this year. I would request all readers of my column review the current (2019 edition) and proposed (2022) language of NFPA 13. Specifically, section 5.2.2.2 in the 2019 edition states, “5.2.2.2* The volume and pressure of a public water supply shall be determined from waterflow test data or other approved method.” The annex section A.5.2.2.2. states, “An adjustment to the waterflow test data to account for daily and seasonal fluctuations, possible interruption by flood or ice conditions, large simultaneous industrial use, future demand on the water supply system, or any other
10 SPRINKLER AGE | MAR/APR 2021
condition that could affect the water supply should be made as appropriate.” For the 2022 edition of NFPA 13, these sections have undergone major changes. I am stating the language as currently proposed: “5.2.2.2.2* Where a waterflow test is conducted to provide water supply information, the raw data from the test shall be evaluated to determine if an adjustment is appropriate. A.5.2.2.2.2 The evaluation can be based on information from the water supply authority, testing, modeling, the fire or building department, or knowledge of the water supply from having worked in the jurisdiction. Depending on how much the pressure changes over time at any given location, an adjustment might or might not be appropriate. For mature water supplies (i.e., ones where new development in the vicinity is unlikely due to the fact that available property has already been fully developed) with fairly stable water usage, or where the waterflow test is conducted at a time of low pressure already, a very small adjustment or no adjustment at all might be appropriate. In an instance where the waterflow test is performed at a time of low demand when it is known that higher demands occur at other times of the day or the year, then a larger adjustment would be appropriate. 5.2.2.2.2.1* The evaluation shall be based on knowledge of the water supply and engineering judgment and shall consider daily and seasonal fluctuations, not extreme conditions. A.5.2.2.2.2.1 The evaluation to determine whether an adjustment should be made and the size of such an adjustment should consider the following variables, applicable to different degrees depending on how and when the test was conducted: 1. Maximum daily use of the water supply 2. Peak hour demand of the water supply 3. Water supply degradation due to planned development 4. Time of day the test was conducted 5. Time of year the test was conducted 6. Elevation of the test location compared to the building where the sprinkler system will be installed CONT. ON PAGE 30

FIRE PROTECTION AND BACKFLOW PREVENTION LACK OF SUPERVISION AND TESTING
T
JACK POOLE, P.E., FSFPE | POOLE FIRE PROTECTION
here has been a significant amount of change and even controversy over the last two decades as to whether backflow protection should be provided on fire protection systems. Not only is there controversy on whether fire protection systems should be provided with backflow protection, but there is also controversy on the type of backflow prevention assembly that should be provided on the different types of fire protection systems. To better understand the need for cross-connection control on fire sprinkler systems there are two questions that must be discussed: 1. What is the threat of the public water distribution system being contaminated as a result of an automatic fire sprinkler system? Based upon statistics from the University of Southern California Foundation for Cross Connection Control and Hydraulic Research and the American Water Works Association Research Foundation (AWWARF) study titled “Impact of Wet-Pipe Fire Sprinkler Systems on Drinking Water Quality,” more than 308 illnesses and one death have been attributed to fire protection cross connections in the United States since 1900. 2. What is the threat of a fire to the public? According to the database maintained by the National Fire Protection Association (NFPA), fire analysis and research, fire consistently kills thousands of people every year in non-sprinklered buildings. The statistics conclude that sprinklers reduce the risk of dying in a fire by at least one-half to two-thirds. Based on the above described statistics, it can be concluded that both fire sprinkler system and backflow prevention assemblies on fire sprinkler systems will improve or protect public health, welfare, and property. At this point in time, both the fire protection industry and the cross-connection control industry have a basic understanding of the potential water quality concerns if a backflow prevention assembly is not installed as well as the potential detrimental effects to a sprinkler system design when a backflow prevention assembly is installed if not properly designed into the system or consistently inspected, tested, and maintained. The two industries need to understand the pros
14 SPRINKLER AGE | MAR/APR 2021
and cons of the issue to determine an agreeable resolution to satisfy the common goal, which is protecting the public health, welfare, and property. The key element to be discussed in this article is the supervision and testing of the backflow prevention assemblies and fire protection systems.
BACKGROUND Let’s start by providing some definitions and briefly discussing the objectives for both sides of the issues. This discussion is applicable to all fire protection systems for which backflow prevention assemblies are installed. The backflow prevention assemblies that are typically utilized on fire protection systems are either a double-check valve assembly, known and referred to as the “double check,” or a reduced-pressure principle assembly, know and referred to as the “RP.” The term “backflow prevention assembly” is defined as the entire device composed of two independently acting check valves, two resilient seated control/shut-off valves with properly located test cocks, which have been tested and listed as a single component/assembly. The requirement for the need of a backflow prevention assembly is typically driven by the adopted building, plumbing, or fire codes and/or the local jurisdiction ordinances or laws. This article is not attempting to tackle the question of when, how, and why backflow prevention assemblies are to be installed but is going to discuss the supervision and testing of backflow prevention assemblies and fire protection systems. The Safe Drinking Water Act requires the water purveyor to provide clean and safe drinking water to the point of discharge. The water purveyor not only has to treat the water they supply, but they also have to ensure that any connection to their distribution system does not contaminate or pollute the supply. In an attempt to ensure its system is protected from any cross connections, the water utility company will typically have a documented Cross Connection Control Program that will describe the when, how, and why backflow prevention assemblies are to be installed, and the testing requirements for these assemblies. To address this issue of supervision and testing, there are several facts that must be addressed to further understand the issue at hand.
1. T he water contained within fire sprinkler systems becomes stagnant, which results in color, taste, and odor problems, which are components of the Safe Drinking Water Act. Therefore, fire protection systems connected to the public water distribution system are considered a “cross connection.” 2. Some fire protection systems are provided with chemical additives such as fire suppression agents (foam), antifreeze, or corrosive inhibitors. The systems with chemical additives create a greater hazard to the public water distribution system, if cross connected, than systems without chemical additives. 3. If the stagnant water or a chemical additive in a fire protection system backflows into the public water distribution system, it may cause public illnesses or possibly death. 4. Not all existing fire sprinkler systems are being maintained in accordance with NFPA 25, Standard for the Testing, Maintenance, and Inspection of Water-Based Fire Extinguishing Systems. 5. Not all existing backflow prevention assemblies are being tested and maintained annually to ensure they prevent the backflow of water under all conditions, as required by the backflow prevention guidelines and requirements. 6. The installation (retrofit) of a backflow prevention assembly on an existing fire sprinkler system may result in a fire sprinkler system that may not have the required flow and pressure to meet the demands of the system. 7. The current backflow prevention assemblies that are typically being installed on fire protection systems have not
been tested to be consistent with how the device will be used. A typical backflow prevention assembly installed on a normal potable system cycles (opens and closes) several times a day or minute, depending on the water usage in the facility. However, the typical backflow prevention assembly installed on a fire sprinkler system will typically only be exercised only during quarterly and annual flow testing, which are required in accordance with NFPA 25. In return, the check valves in a backflow prevention assembly on a fire system may not be exercised for months or even years, causing the checks to stick and not open when required. 8. One hundred percent of the water contained within a fire sprinkler system will not backflow into the public water distribution system due to the vacuum that is created within the sprinkler system. Limited simulated backflow testing performed as part of the American Water Works Association Research Foundation (AWWARF) research project entitled “Impact of Fire Protection Systems on Drinking Water Quality” concluded that an average of 100 gallons would backflow from a typical wet pipe fire sprinkler system. 9. Depending on the length of the underground lead-in from the public water distribution system main to the automatic sprinkler system riser and the diameter of the main, the typical 100 gallons of water that may potentially backflow may never physically reach the public water distribution system. It takes approximately 100 gallons of water to fill 65 ft of 6-in. diameter pipe.

10. If and when the contaminated or polluted water from the fire sprinkler system backflows into the public water distribution system, this water will typically be diluted with potable drinking water, which will reduce the levels of contamination or pollution but may still exceed the maximum contaminate levels contained in the Safe Drinking Water Act. Now that several of the facts have been laid on the table, the need for supervision and testing of backflow prevention assemblies and fire sprinkler systems should be discussed.
THE NEED FOR SUPERVISION What does the term “supervision” really mean in the fire sprinkler industry, and is the use of this term different to the cross-connection control industry? Supervision in the fire sprinkler industry typically refers to control valves on the fire sprinkler system to make sure they are maintained in the open position. Supervision in the cross-connection control industry typically refers to the overall implementation and maintenance of its Cross-Connection Control Program. The term “control valve” on a fire sprinkler system is typically an OS&Y or indicating butterfly valve that controls the water supply to the sprinkler system. The control valves on a fire protection system are required to be supervised to ensure they are maintained in the open position. The method of supervision varies depending on the adopted codes and standards and the local jurisdiction requirements. Most control valves on fire sprinkler systems are either provided with an electronic tamper switch that is connected to the building fire alarm system or provided with a chain and padlock to secure the valve in the open position. When a backflow prevention assembly is installed on a fire sprinkler system, the OS&Ys or indicating butterfly valves should be supervised to ensure they do not get accidentally closed, eliminating the water supply to the automatic sprinkler system.
THE NEED FOR TESTING I believe we can all agree that if the specific system or equipment is not tested or maintained, there is no need to

have it installed. However, we all know that is not the answer to ensuring safe drinking water or adequate fire protection. The cross-connection control industry typically requires annual backflow performance testing to ensure the assembly will prevent backflow. This testing is typically required to be performed by a certified backflow prevention assembly tester. The local water purveyor or Authority Having Jurisdiction (AHJ) will typically track the annual testing of the assemblies and provide the testing protocol for each specific type of assembly. Furthermore, some jurisdictions may require the technician performing the annual backflow performance testing of the backflow prevention assembly also be a licensed or certified fire sprinkler contractor, in addition to being a certified backflow prevention assembly tester. The importance of the “backflow performance test” is to ensure the backflow prevention assembly will function as required and prevent the water from backflowing into the public water distribution system. NFPA 25 provides the specific criteria for the inspection, testing, and maintenance of fire sprinkler systems. NFPA 25 also addresses the inspections and testing required for backflow prevention assemblies. NFPA 25 identifies one specific annual test, which is a forward flow test to excise the assembly. The importance of the “forward flow test” is to ensure the check valves in the backflow prevention assembly will open, allowing an adequate amount of water to pass through the assembly. An adequate amount of water is defined as the system demand, including any required inside hose demand for the specific sprinkler system. Even though not specifically required by NFPA 13, Standard for the Installation of Sprinkler Systems, I understand there are many jurisdictions that require the forward flow testing to be measured with a pitot gauge or some other method to determine the quantity of water being flushed through the backflow prevention assembly to ensure a minimum flow of the system demand is being achieved. In my professional opinion, if the method to perform the

Figure 3. Forward flow test outlet with bypass control valve, interior of the building. annual forward flow test is made easy, this is more likely to be performed by the contractor than having to connect a bunch of hoses to a discharge header and measuring the flow with a pitot gauge. To comply with the requirement in NFPA 13 and to make the testing easier, my recommendation would be to install a tee of the same size as the backflow prevention assembly immediately downstream of the backflow prevention assembly on the sprinkler riser and provide a butterfly valve on the discharge side of the tee, which will then discharge to the outside to a safe location. On the exterior of the building, a pipe increaser with expanded metal welded to the outlet can be installed to be used as the flushing outlet to achieve the full-forward flow test required by NFPA 25. The pipe increaser and expanded metal over the outlet will reduce the velocity at the discharge orifice as well as break up the flow stream from the outlet to reduce water damage and erosion. (See Figures 1 and 2.) The size of the flushing pipe assembly being the same size as the backflow prevention assembly will ensure that the check valve and working components within the backflow prevention assembly will be exercised to the maximum extent possible and should greatly exceed the minimum demand of the automatic fire sprinkler system. A second option is to pipe around the fire department connection (FDC) check
valve and then install the control valve and pipe increaser with a diffuser on the exterior of the building along with the FDC. (See Figures 3 and 4.) Unfortunately, the testing of the backflow prevention assemblies or the fire sprinkler systems is not always performed at the frequencies required by the codes or standards or performed in accordance with the testing criteria. Both the backflow prevention assemblies and the fire sprinkler systems are designed and installed to protect public health, welfare, and property. If neither are inspected, tested, or maintained correctly, there is a greater chance they will not work properly when needed. Both the fire protection community and the backflow prevention community want to protect drinking water and keep the public safe from fire. In order to accomplish these goals, both industries must understand the importance of the other industry to help ensure our drinking water is protected, and the fire sprinkler systems work as designed to save lives and protect property. n ABOUT THE AUTHOR: Jack Poole, P.E., FSFPE, is a principal of Poole Fire Protection, Inc. in Olathe, Kansas.

REBECCA HERRING | AMERICAN FIRE SPRINKLER ASSOCIATION
his year marks American Fire Sprinkler Association (AFSA)’s 28th Annual National Apprentice Competition. This year’s live, in-person competition will be held in the exhibit hall at AFSA40: Convention, Exhibition & Apprentice Competition September 18-21, 2021, at the JW Marriott San Antonio Hill Country Resort & Spa.
HISTORY OF THE COMPETITION AFSA’s Annual National Apprentice Competition (NAC) was created in 1994 by the late Robert L. (Bob) McCullough, then chair of the Apprenticeship & Education Committee, to promote apprentice training and give recognition to the apprentices who are actively enrolled in the AFSA apprenticeship program. Each year, the competition continues to attract more fire sprinkler apprentices from AFSA local chapters and member training programs from all corners of the United States, bringing them together for the fire sprinkler industry’s foremost showcase of training excellence. Enrolling your apprentices in AFSA’s apprentice training program not only offers excellent education and a fulfilling career but is also the ticket to competing in the AFSA apprentice competition. The competition consists of two portions: a written test, based on all four levels of AFSA/NCCER Contren® Learning Series Sprinkler Fitter curriculum, followed by a live competition practical in front of a live audience in the AFSA exhibition hall at AFSA40. When AFSA was formed 40 years ago, its founders had a vision: be the industry leader in fire sprinkler education and training. This competition is a piece of that vision come to life. “AFSA’s National Apprentice Competition is the premier opportunity to highlight knowledge and capability for the fire sprinkler apprentice,” says AFSA

Director and Co-Chair of AFSA’s Apprenticeship & Education Committee Rod DiBona, Rapid Fire Protection, Inc., Rapid City, South Dakota, who was a finalist and competitor at AFSA’s 1985 competition, held in Palm Desert, California (see photo at right). “To have one of the top seven scores in the nation is a badge that can be worn with pride for an entire career, both for the individual and the sponsoring company. We are proud to put such an emphasis on the future of our industry and invite all member companies to participate and to encourage all of their apprentices to compete. There is great value in the process, regardless of the result.”
ONLINE ASSESSMENT AFSA will once again utilize online testing for Phase I of the two-phase competition. This testing method provides many benefits for those competing. First and foremost, keeping safety and social distancing at the top of mind, the continued offering of digital testing helps AFSA to comply with COVID-19 regulations across the country. Secondly, the system increases the convenience of testing for all apprentices. Apprentices schedule a time during the testing window and test online when and where it is convenient for them. Digital testing continues to streamline the testing process for all involved and allows more apprentices than ever before the opportunity to raise the stakes by participating in the competition.
IGNITE INDUSTRY PASSION The NAC offers a little something for everyone, from the excitement that can rock a whole company to the personal victories
each apprentice experiences throughout the competition and testing. New apprentices feel the excitement and a healthy sense of competition with their peers at the prospect of winning top prizes and accolades for their companies, and companies benefit by having an extremely well-trained, efficient, and more motivated workforce. Even those who are not participating in the competition have the motivation of seeing hardworking apprentices continue to strive to improve the industry and its reputation for all. The competition has been and remains an important reminder of training and industry excellence that shines throughout the year and is a hallmark of AFSA conventions.
COME COMPETE AFSA invites all interested apprentices enrolled in its apprenticeship training program to participate—this year, the winner could be you! Besides an expense-paid trip to San Antonio to compete at AFSA40, each of the top seven national finalists received a commemorative plaque, tools, cash prizes, and a complimentary convention registration for their employer. Winners will be crowned at the Awards Party at Knibbe Ranch, where attendees will enjoy live entertainment, fantastic food, and ranch activities. The competition may only come once a year, but its legacy and excitement extend far beyond, and this year’s Texas-sized competition will be one for the history books! The deadline to register to compete in this year’s competition is April 16, 2021. To learn more, visit firesprinkler.org/apprentice. n

A MEANS TO AN END BACKFLOW PREVENTER TESTING REQUIREMENTS IN NFPA 13
F
KEVIN HALL, M.ENG., P.E., CWBSP, PMSFPE | AMERICAN FIRE SPRINKLER ASSOCIATION
or many years, contractors have been able to comply with the generalized language in NFPA 13, Standard for the Installation of Sprinkler Systems, regarding the installation of backflow preventers. As a legacy requirement in place since the 1996 edition of NFPA 13, there have not been any substantial revisions until recently. With the evolution of the testing requirements for backflow preventers, specifics have been added to the body of NFPA 13 due to a general lack of compliance that has been observed throughout the industry. The requirement to provide a means to forward flow test a backflow preventer has long been in the standard. Since the requirement’s inception, there has been an annex note associated with the requirement to explain the committee’s intent. Per NFPA 13, 1996 edition: 2-7.4* Backflow Prevention Valves. Means shall be provided downstream of all backflow prevention valves so that flow tests of the valve can be conducted. A.2-7.4 The full flow test of the backflow prevention valve can be performed with a test header or other connection downstream of the valve. A bypass around the check valve in the fire department connector line with a control valve in the normally closed position can be an acceptable arrangement. When flow to a visible drain cannot be accomplished, closed loop flow can be acceptable if a flowmeter or site glass is incorporated into the system to ensure flow. As this requirement has been in the standard for so long, then why is the presence of a means to adequately forward flow test a backflow preventer without system modification a rarity? The issue lies with the ambiguity in the requirement. While there is sufficient direction provided in the annex, it is only a suggestion and not enforceable unless specifically adopted by a local jurisdiction. This leaves the Authority Having Jurisdiction (AHJ) to determine what an acceptable “means” will look like, based on the enforceable language found in the body of the standard. For the 2019 edition, the technical committee addressed some of these ambiguities with a new subsection: 16.14.5.1.1 The arrangement required in 16.14.5.1 shall be serviceable without requiring the owner to modify the system to perform the test. While the acceptable “means” is still up for interpretation, it is now clear what is not acceptable. If your jurisdiction is using an earlier edition of the standard, you may still run into a check valve

that has to be reversed. But it is important to consider the latest requirements that have been debated and accepted by the technical committees to provide an economical product for our industry that can be easily tested and maintained over the life cycle of a system. The most significant changes to the installation requirements for the testing of backflow preventers occurred during the last revision cycle for the 2022 edition of NFPA 13. Specific requirements for backflow preventer testing arrangements were addressed in the second draft. Second Revision No. 1163 (SR-1163) changed the prescriptive requirements. The new language mirrored the testing requirements for pressure-reducing valves that were updated during the first draft phase. SR-1163 made the following changes: 16.14.5.1* Backflow Prevention Valves. Means A test connection shall be provided downstream of all backflow prevention valves for the performance of forward flow tests required by this standard and NFPA 25 at a minimum flow rate of the system demand including hose allowance where applicable. 16.14.5.1.1 The arrangement required in 16.14.5.1 shall be serviceable without requiring the owner to modify the system to perform the test. 16.14.5.1.1 A 2-1⁄2 in. (65 mm) hose valve shall be provided downstream of the backflow prevention valve for every 250 gpm (950 L/min) of flow rate required by the system demand including hose allowance where applicable. 16.14.5.1.2* Existing hose connections downstream of the backflow prevention valve shall be allowed to be utilized. 16.14.5.1.3* Other means shall be permitted as long as the system doesn’t require modification to perform the test and it is sized to meet the system demand. These new requirements may seem excessive, but when you think about it, most sprinkler systems already have these arrangements. If you have a fire pump to provide additional pressure to your system, the test header will suffice. If you have a combined standpipe system, the outlets on the standpipe will suffice. These testing devices should be appurtenances that are already installed on the system, and that is explained in the new annex language: A.16.14.5.1.2 Hose connections on a standpipe or on a fire pump test header can be utilized for the full flow test. A.16.14.5.1.3 Providing another means is at the discretion of the designer in consultation with the owner or developer. Any number of arrangements would be acceptable as long as the flow through the backflow prevention valve can be measured to verify it is equal to or greater than the system demand. One example is
the use of the fire department connection as long as it will accommodate the required flow and the check valve has a bypass with a shut-off valve provided for this purpose. In reality, the new requirements proposed for the 2022 edition are not new at all. These are common-sense requirements that should be on the system anyway but needed to be spelled out due to the lack of compliance throughout the industry. A designer can still install a generic “means” to test the backflow preventer, provided it is acceptable to the AHJ. The only difference is that it is the exception and not the rule. To drive the point home even further, note that specific language was added to the working plans requirements for the 2022 edition: 28.1.3 Working plans shall be drawn to an indicated scale, on sheets of uniform size, with a plan of each floor, and shall show those items from the following list that pertain to the design of the system: […] (18) Location and labeling of all system flushing, forward flow, water flow alarm, and test and drain locations the the working more then of anM/S organized checklist FromTo l tomake r: During Octoberplans 4 meeting, Council Chair Mike Dooley presented Chuck and chaotic junk drawer, the technical Kittsless withofa aplaque recognizing his service to the AFSAcommittee M/S Council. revamped the entire list to group items into a logical order and include all items that are necessary to be called out on a working plans submittal. AHJs and peer reviewers alike should be checking for details on the drawings, describing the planned provisions to forward flow test backflow prevention equipment. In the end, as long as a means to forward flow test the backflow preventer is provided, the requirements of the standard are satisfied. The new requirements provide clarity on the intent, but there is still debate on how to verify flows and if they even need to be verified (measured). The key item to remember is that a backflow preventer is typically a plumbing device intended to be used on plumbing systems with circulating water. The forward flow test is necessary to exercise backflow preventers installed on sprinkler systems with stagnant water to verify that in the event of a fire, the clappers will operate and the appropriate amount of water will be dispersed on the flames. n

TRAINING BEYOND THE STORM AFSA’S DALLAS SCHOOL GOES ON FOLLOWING HISTORIC 100-YEAR WINTER EVENT
A
s Texas faced record-low temperatures and snow and ice made roads impassable, the state’s electric grid operator lost control of the power supply, leaving 4.5 million without access to electricity and many subject to boil orders. Due to the prolonged power outages and record-breaking freezing temperatures, pipes froze and then burst Thursday, February 18, 2021. The American Fire Sprinkler Association (AFSA) offices were not immune and were forced to shut down for a couple of days while repairs were made. Despite the challenges days prior, the team at AFSA quickly jumped into action to prepare for its Beginning Fire Sprinkler System Layout Planning School, beginning February 22, 2021, to ensure their members never missed a beat. “The challenges the winter storm put on AFSA never swayed our team from moving forward with the class,” said Marlene Garrett, CMP, senior director of meeting and education services at AFSA. “Our team understands the importance of offering training no matter what obstacles are put in front of us. We provide the best service to our members always.” Recognizing that a dozen members would be arriving at the Dallas headquarters in mere hours to learn the basics of design, a small team of staff mobilized over the weekend to their offices to save the student’s printed instructional materials and gathered the necessary supplies, such as calculators, drafting tables, and rulers used when

learning to do hydraulic calculations by hand. Others worked to secure classroom space at the Residence Inn Dallas Addison/Quorum Drive, where the students were housed during the two-week school, to conduct the off-site training. “I appreciate [the staff ] not saying ‘no’ but just asking ‘how.’ That’s what it takes to deal with adversity and get the job done,” commented AFSA President Bob Caputo, CFPS, who personally picked up and delivered supplies to the new training site over the weekend. “I am proud of everyone at AFSA for doing what it takes to deliver for our members. Team AFSA can make it happen!” Beyond the staff, the members did what the fire sprinkler industry does
best—they showed up no matter what. Every single registered student arrived at the hotel ready to learn at 8:00 a.m. on the Monday following one of Texas’ worst weather catastrophes. This dedication further underscores the commitment of the fire sprinkler community to training.
AFSA’S DESIGN SCHOOL HITS THE ROAD Are you interested in your employees learning sprinkler system design? In addition to schools held at its training center in Dallas, Texas, AFSA’s popular Beginning Fire Sprinkler System Planning School is hitting the road for the first time ever. Upcoming 2021 dates include April 12-23 in San Diego, California; May 17-28 in Baltimore, Maryland; July 19-30
in Philadelphia, Pennsylvania; August 16-27 in Baton Rouge, Louisiana; September 27 - October 8 in Philadelphia, Pennsylvania; and November 8-19 in Sacramento, California. The school teaches the essential elements of system layout in accordance with NFPA 13, Standard for the Installation of Sprinkler Systems. Recent upgrades have been made to the school’s content, updating it from the 2016 edition to the 2019 edition of the standard. This class is designed for trainees and entry-level technicians with at least six months’ experience and those with experience in the sprinkler trade looking to make the transition to design. The school presents a comprehensive, practical approach to preparing fire sprinkler system drawings and will prepare the student to: • Accelerate the comprehension of plans and various types of building construction for proper sprinkler spacing applications. • Determine the proper and economic planning of sprinkler system layout and installation methods. • Know the importance of sprinkler specifications, types of pipe, hangers, fittings, flow tests, etc. • Learn to develop shop drawings from start to finish. • Learn to coordinate with other trades—plumbing, mechanical, structural, and electrical. • Perform manual hydraulic calculations by hand, preparing the student for a more natural decision-making process when using a computer to perform hydraulics. • Prepare shop drawings in class for projects with different applications. The school is taught by AFSA’s expert technical services staff, including Technical Programs Specialist Tom Noble, CET, CFPS, CWBSP; Coordinator of Engineering & Technical Services Kevin Hall, M.Eng, P.E., CWBSP, PMSFPE; and Vice President of Engineering & Technical Services John August Denhardt, P.E., FSFPE. “For our contractor members that were deemed essential employees, the
pandemic has not slowed them down, so the need to train their employees remains,” said Denhardt. “Here at AFSA, we are training as safely as possible by following all CDC, state, and local guidelines. Like many of our members, we’re eager to get to work training and supporting our members to do their jobs to the best of their ability.” Comments on evaluations from recent graduates include: • “Extremely incredible class! Instructors are very patient and extremely knowledgeable on the subject. Book was very well put together.” • “I thoroughly enjoyed the course and learned a great deal. My confidence in my calculations has grown immensely thanks to the knowledge and teaching of Tom and Kevin.” • “This was a great course in preparation for my upcoming NICET Level I and NICET Level II exams.”
COVID-19 PREVENTION MEASURES ENSURE SAFETY AFSA takes the current health situation seriously and works hard to ensure students’ safety. “We are following all of the CDC recommendations—wearing masks, maintaining social distance, checking temperatures, using Plexiglas dividers, and cleaning and disinfecting surfaces,” continued Garrett. “The need for training hasn’t stopped, and AFSA has taken the necessary precautions to meet that demand safely.”

efore there was ever an American Fire Sprinkler Association (AFSA), there was the Independent Sprinkler Training Committee (ISTC). During the 1981 NFPA convention in Dallas, ISTC held its third meeting, with over 60 people in attendance. At the time, the ISTC’s goal was to establish a national apprentice training program for non-union, or merit shop, fire sprinkler contractors. Until the founding of AFSA in New York City on September 16, 1981, there was no organization to meet this growing need. In November 1981, the association’s early leaders published their first newsletter, which they named Sprinkler Age, announcing “a major new force in the fire sprinkler industry.” AFSA’s first Executive Director, Joe Mulrine, located the association’s headquarters in New Haven, Connecticut. In the beginning, Mulrine, with his staff of two, worked to receive permission from the Ministry of Education in Ontario to utilize the Canadian Fire Sprinkler Fitter Correspondence courses to train fitters in the United States. On November 17, 1981, the AFSA National Apprenticeship and Training Standards were submitted to the National Bureau of Training in Washington, D.C., for approval. On January 7, 1982, these standards were granted approval and issued the National Registration number of N-92021. The first batch of apprentice correspondence courses, officially titled, Automatic Sprinkler Protection: Basic Training Series, was made available for sale shortly thereafter. It was official: AFSA was a training association. In 1983 Frank Riseden became the second executive director, a small staff was hired, and the association’s headquarters were moved to Dallas, Texas, where they remain today. As the association staff grew, Riseden’s title was changed to president. During this timeframe, nationwide seminars and the first designer series of correspondence courses were also introduced. Soon, people all over the country were taking notice. AFSA gained legitimacy on a national scale when the first representative of AFSA was appointed to serve on a National Fire Protection Association (NFPA) Technical Committee in 1983. Seeing the importance of involvement, the association’s leadership soon expanded the membership benefits to include technical services in 1984, with the hopes that AFSA would increase its technical role to include NFPA committees. In 1986, Willie Templin and founding AFSA member Ed Smith had gained the association’s first seat on the NFPA 13, Standard for the Installation of Sprinkler Systems, committee. The Technical Services Department of

AFSA gathered in San Antonio, Texas, in 1984 and several times since. This year, members will meet again in the Alamo City to celebrate AFSA’s 40th anniversary. today offers expert technical advice through informal interpretations and has a prominent presence on 35 NFPA technical committees, and is a leading authority in the standards-making process. As AFSA’s focus on education intensified, it expanded its offerings to include basic and advanced fitter and designer training. In 1985, the association launched the first session of its “Principles of Fire Sprinkler System Design,” an early precursor to AFSA’s popular two-week Beginning Fire Sprinkler Planning School. Building on its apprentice training, the AFSA National Apprentice Competition debuted during the 1994 AFSA Convention & Exhibition in Fort Lauderdale, Florida, and years later, it is still the premier sprinkler fitter competition with hundreds of apprentices sitting for the qualifying exam annually. From one apprentice training course, AFSA has grown to offer a variety of correspondence courses for every type of professional in the fire sprinkler industry, classes at AFSA’s training center, nationwide traveling seminars, online courses, and webinars. The association continues to expand upon its mission of providing training for the fire sprinkler contractor, launching its Inspection, Testing, and Maintenance Inspector Development Program in 2016. In 2019, John August Denhardt, P.E., FSFPE, joined the staff as its Vice President of Engineering & Technical Services and he, along with his staff, expanded and updated many of the association’s technical trainings, including several free webinar series such as Sprinkler Challenge and Fitter Zone. During the pandemic when travel was limited for some, the Technical Services team took AFSA’s Beginning Fire Sprinkler Planning School on the road, crisscrossing the United States from San Diego to Tampa with stops in between.

In 2020, AFSA named industry veteran Bob Caputo, CFPS, as its president, further reinforcing its focus on education and technical excellence.
GETTING THE WORD OUT AFSA’s third President, Steve Muncy, who succeeded Frank Riseden in 1992, led the association into the world of technology, helping to create the association’s first website, membership database, and email system in 1995. Seeking to get the fire sprinkler message out to the larger public, AFSA announced its first annual national High School Senior Scholarship Contest during the 1996-97 school year, with the goal of educating high school seniors about the life-saving benefit of sprinklers. The high school scholarship went online at afsascholarship.org in 2006 and now educates nearly 70,000 entrants annually. In 2009, the program expanded to include the Second Chance Scholarship. This award was different from many scholarships in that all those seeking to pursue a college degree or trade school education—including returning military, parents returning to the workforce, and anyone with a high school diploma or GED—were encouraged to apply. At the same time, AFSA was also gearing up its member communications. In 1996, AFSA introduced its SprinklerForum, a first of its kind in the industry email-based discussion group still in use today. Over the years, AFSA has expanded the ways in which it communicates with its members introducing several e-newsletters, like Contractor Network and Tech Update. In 2008, AFSA launched into the social media forefront with Facebook, LinkedIn, Twitter, YouTube pages, adding Flickr in 2010, followed by Instagram in 2016. In 2009, its member publication Sprinkler Age began publishing a digital edition, complementing its long-standing print publication, and in 2015, it went a step further, joining the blogosphere at SprinklerAge.com. In 2014, AFSA founded its young professional group, the NextGen Initiative, to engage and develop professionals, 40 and under, in the industry. Focusing on mentorship, pathways to jobs, and career development, the group hosts an annual NextGen Day at AFSA’s annual convention and a popular quarterly webinar series.
Past Chairs of the Board Jack Viola (left) and Don Becker (right) take some time to visit during the 2013 convention at Caesar’s Palace in Las Vegas.
40 YEARS STRONG – 1981 TO 2021 Over the past 40 years, AFSA has grown from a handful of dedicated volunteers who saw an opportunity to better the industry through collaboration and education to a nationally recognized organization with over 1,000 member companies, 32 local chapters, and two state affiliates. Throughout the years, AFSA leaders have kept the association on a successful path with a bright horizon ahead. We congratulate our founding fathers for their hard work and look forward to working with future generations to secure AFSA’s place in history as the fire sprinkler industry leader.

BACKFLOW PREVENTION DEVICES PRESSURE LOSS AND IMPACTS JOHN AUGUST DENHARDT, P.E., FSFPE | AMERICAN FIRE SPRINKLER ASSOCIATION
A
lmost all water-based fire protection systems utilizing potable water require some type of backflow prevention device to protect the potable water supply from contamination. Typically, these devices are required by the adopted plumbing code, not NFPA 13, Standard for the Installation of Sprinkler Systems. While these devices are necessary, their impact on a waterbased fire protection system must be accounted for in the system’s design. The 2019 edition of NFPA 13, section 27.4.5.6(19)(F) requires, “The pressure loss assigned the backflow device when included on a system” to be included on the detailed worksheet for hydraulic calculation Where is the pressure loss data obtained from? How does one accurately account for the pressure loss? As part of the UL classification of backflow prevention devices, the pressure loss is documented. The pressure loss is
expressed with curves developed based on testing by Underwriters Laboratory per UL 1469 Edition 2, Standard for Strength of Body and Hydraulic Pressure Loss Testing of Backflow Special Check Valves. Each specific manufacturer, model, style, size, and selected options will have different curves. It is critical that the designer use the exact make and model backflow prevention device when determining the pressure loss. In addition, the designer needs to know the calculated water flow rate demand because the pressure loss varies based on the water flow rate. Depending on the hydraulic calculations software the designer uses, the method of inputting the pressure loss versus water flow curve does change. The shop drawing should indicate the backflow prevention device manufacturer, model, style, size, and selected options. An equipment data sheet should also be submitted highlighting the pressure loss curve utilized in the hydraulic calculations.
Figure 1. Example of a pressure loss curve for a 4-in. backflow preventer. The single asterisk denotes the rated flow and the double asterisk denotes the UL tested flow.
28 SPRINKLER AGE | MAR/APR 2021
A typical pressure loss curve is shown in Figure 1. What is critical to understand, in many cases, is that the pressure loss can be higher at low water flow rates. Sometimes, oversizing a backflow prevention device can result in a higher-pressure loss than one which is properly sized. All backflow prevention devices utilized in water-based fire protection systems are manufactured to either AWWA C510-17, Double Check-Valve Prevention Assemblies, or AWWA C511-17, Reduced-Pressure Principle Backflow Prevention Assemblies. These standards list the maximum pressure loss for a device to comply with the standards. AWWA C510 states in section 4.2.1.2 “Rated flow and allowable pressure loss - The maximum allowable pressure loss at any rate of flow, from zero and up to and including the maximum rated flow for the indicated size, shall not exceed the values shown in Table 1.” For example, Table 1 of AWWA C510 allows a 4-in. double check-valve backflow prevention device to have a rated water flow rate of 500 gpm at a maximum loss of 10 psi. In fact, Table 1 of AWWA C510 for all sizes and rated water flow rate, the maximum pressure loss is 10 psi. How many double check-valve backflow prevention devices on the market have a pressure loss near 10 psi? AWWA C511 has similar language and requirements. Section 4.2.1.2 states, “Rated flow and allowable pressure loss – The maximum allowable pressure loss at any rate of flow, from zero
and up to and including the maximum rated flow for the indicated size, shall not exceed the values shown in Table 1.” For example, Table 1 of AWWA C511 allows a 4-in. reduced-pressure principle backflow prevention device to have a rated water flow rate of 500 gpm at a maximum loss of 12 psi. In fact, Table 1 of AWWA C511 for all sizes and rated water flow rate, the maximum pressure loss is 12 psi. How many reduced-pressure principle backflow prevention devices on the market have a pressure loss near 12 psi? For projects which must follow the Unified Facilities Code (UFC) 3-600-01, Fire Protection Engineering For Facilities, 8 August 2016 with Change 5, 24 September 2020 document pressure losses for backflow prevention devices are handled differently than NFPA 13. Section 9-6.3.5 of UFC 3-600-01 states, “Hydraulic calculations must include a minimum pressure drop across backflow preventers. For a reduced pressure backflow preventer, use a minimum of 12 psi. For a double check backflow preventer, use a minimum of 8 psi.” I understand that the 12 psi pressure loss is taken from AWWA
C511, but I am not sure where the 8 psi pressure loss is taken from. AWWA C510 allows at 10 psi pressure loss. Over the years, the manufacturers have adapted their designs to minimize pressure loss. Lower pressure loss is always better in a water-based fire protection system, so a designer should not select a backflow prevention device based on pricing alone. Several factors must be considered such as the type required, product availability, physical size, physical weight, pressure loss at the water flow rate of your designs, cost, and, if required, the ease/difficulty of monitoring the control valves. If your project requires compliance with the UFC 3-600-01, selecting a higher pressure loss backflow prevention device has no impact on your design. Also, the designer needs to understand any local Authority Having Jurisdiction (AHJ) requirements with regard to selection and physical location of the backflow prevention device. If a fire pump system is being supplied by the backflow prevention device, NFPA 20, Standard for the Installation of Stationary Pumps for Fire
Protection, needs to be consulted for specific requirements. The 2019 edition of this standard states: “4.29.3 Devices in Suction Piping. Where located in the suction pipe of the pump, check valves and backflow prevention devices or assemblies shall be located a minimum of 10 pipe diameters from the pump suction flange. 4.29.3.1 Where a backflow preventer with butterfly control valves is installed in the suction pipe, the backflow preventer is required to be at least 50 ft from the pump suction flange (as measured along the route of pipe) in accordance with 4.16.5.4. 4.29.4 Evaluation 4.29.4.1 Backflow Prevention Device 4.29.4.1.1 Where a backflow prevention device or assembly is installed in connection with the pump, special consideration shall be given to the increased pressure loss resulting from the installation. 4.29.4.1.2 Where backflow prevention device is installed, the final arrangement shall provide effective pump performance at the lowest

permissible suction pressure. 4.29.4.1.3 The discharge flow rate shall meet or exceed the fire protection system design flow. 4.29.4.1.4 The discharge flow rate shall meet or exceed 100 percent of the fire pump rated flow rate. 4.29.4.1.5 Determination of effective pump performance shall be documented by engineering calculations and tests. 4.29.4.1.6 Retroactive installation of a backflow prevention device shall not reduce the suction pressure below that permitted in this standard and accepted by the authority having jurisdiction. 4.29.4.1.7 Retroactive installation of a backflow prevention device shall not result in a discharge pressure that does not meet the maximum system demand and 100 percent of the rated flow rate for the fire pump.” Some of the above language is new or revised for the 2019 edition. What I specifically find interesting is the language in sections 4.29.4.1.3 and 4.29.4.1.4. What is meant by the language “the discharge flow rate?” This
language is not the fire pump rated flow rate since the technical committee called that language out specifically. Is this the rated water flow rate UL or AWWA C510/C511 uses? Each agency uses a different value which might produce different selections. For example, a 750-gpm rated fire pump system will require at least a 6-in. backflow prevention device if following AWWA requirements and a 4-in. backflow prevention device if following the UL requirements. I will need to research this as I am not sure the intent of the current language. As you can see by the above information, the pressure loss of a backflow prevention device might not be a straightforward as one would think. But understanding the requirements will assist a designer in selecting the most appropriate backflow prevention device for their project from a hydraulic impact perspective, and the resulting hydraulic calculations will be performed correctly. n

7. Elevation of the water supply at the time of the test 8. How close the flow generated during the test was to the system demand There is no single specific adjustment applied to a water supply that would be appropriate for every sprinkler system. The design professional needs to work in conjunction with the authority having jurisdiction to determine the appropriate adjustment. Where an authority having jurisdiction has already determined a specific buffer between test results and the demand of the sprinkler system, it is not the intent of this standard to add an additional safety factor or safety margin; the buffer mandated by the authority having jurisdiction serves the purpose of the adjustment.
30 SPRINKLER AGE | MAR/APR 2021
In the absence of information from the design professional and the authority having jurisdiction, it would be appropriate to make an adjustment to the raw data from a flow test by either obtaining information from the water utility or using a reasonable adjustment. Such an adjustment should be determined through a conversation with the authority having jurisdiction. It is important to note that not all water supplies have a linear relationship of flow to pressure. As flow demand increases, additional water can be provided into the system through multiple pumps, causing complex geometries to the pressure and flow relationship at any given point in the system. Creating multiple flow conditions during a test and getting as close as possible to the sprinkler system demand will assist in gaining a complete understanding of the water supply. 5.2.2.2.2.2
If an adjustment is determined to be appropriate, it shall be applied to the waterflow test data prior to comparison with the sprinkler system demand. 5.2.2.2.2.3 Where the water supply information is obtained from another approved method other than a waterflow test, that method shall consider daily and seasonal fluctuations, not extreme conditions.” As I stated earlier, I will discuss the technical issues and potential liability issues we see with the new language in the May/June edition of Sprinkler Age. We will need the members of AFSA to make the voices known to NFPA on this issue. AFSA will let you know how to make your voices heard. I appreciate your effort on this issue. n

Approved Fire Protection Co., Inc., shared some of their favorite AFSA memories and things they’ve learned through the years.
HOW DID YOU GET INVOLVED IN THE FIRE SPRINKLER INDUSTRY? Gnifkowski: “I was hired to manage PMC in 1972 and inherited the company a year later.” Pein: “My great grandfather started this company in 1930. My grandmother and then father ran the company concurrently, and when my father needed to retire, I stepped in to help transition temporarily. Now I am 25 years into this ‘temporary position’ as the sole owner and loving every minute of working in this industry.” HOW DID YOU GET INVOLVED WITH AFSA? Gnifkowski: “I [realized joining AFSA] was the only way to get merit-shop apprentices trained.” Pein: “When I started working in the company in 1995, I wanted to learn all facets of the industry. I became enamored with sprinklers and felt the need to get involved outside of the company. I became a member of AFSA, worked with the executive committee on legislation for a few years, then passed the baton on to one of my project managers, who spent nine years on the Board.”
WHAT IS YOUR FAVORITE OR MOST USED AFSA BENEFIT? Gnifkowski: “Just keeping pace with the industry takes pretty good care of me.” Pein: “I personally utilize the training and education— webinars and live courses.”
WHAT IS YOUR FAVORITE AFSA AND/OR AFSA CONVENTION MEMORY? Gnifkowski: “Meeting the other players around the country. I especially cherished my friendship with the FPC family.” Pein: “I am sorry to say I have not attended any of the conventions, but my team comes back from most of them re-energized and a bit exhausted. They enjoy the networking and the education. I would be lying not to say they also enjoy the evening fun with other members.”
WHAT IS THE MOST SIGNIFICANT CHANGE YOU’VE SEEN IN THE INDUSTRY? Gnifkowski: “Continual improvement in all areas of fire protection.” Pein: “I have only been involved for 25 years, but I have seen the growth in the entire fire protection industry—keeping up with the new technologies while maintaining the industry’s integrity. The laws and codes have come a long way in the past two decades, keeping their relevance in respect to the new smart buildings and the future of IT in our industry.”
WHAT’S THE KEY INGREDIENT TO YOUR SUCCESS?
REFRESH YOUR FLOW TESTING
Gnifkowski: “Hard work.” Pein: “Oooh, that is a big question. I look at my success as the success of the company. I would have to pinpoint our success to great core values. Our team is comprised of great talent, great communicators, and value-based individuals. We are diligent about filling our team with more folks of the same values, which ensures we grow bigger and stronger every day.”
IF I WEREN’T WORKING IN FIRE PROTECTION, I WOULD BE... Gnifkowski: “Probably dead! This 15th anniversary is my ‘second coming.’ I originally retired in 1990 and came back in 1994.” Pein: “A research chemist, which is where I was working when my father asked me to step in and help him… I miss it very much. I do love what I am doing today in the fire protection industry but would run back to the lab if I could.”
CELEBRATING AFSA MEMBERS AFSA looks forward to celebrating with more members during its 40th-anniversary year. The AFSA membership team is excited to be rolling out new membership programs—a sixmonth trial membership for contractors, one-year trial membership for Authorities Having Jurisdiction (AHJs), and the “Be a Member, Bring a Member” program. “Dominick, Meda, and I are excited to be serving our members!” says Lecair. “These programs are already opening the doors for new members to see and experience all that AFSA has to offer.

50 SPRINKLER AGE | MAR/APR 2021
JANUARY/FEBRUARY ANSWERS
All answers are based on the 2019 edition of NFPA 13. Questions may have more than one correct answer. 1) B. NFPA 13 section 28.2.2.1 permits a drop of 1½ psi over the 24-hour duration of the test. After acceptance, NFPA 25 permits a drop of 3 psi over a 2-hour test. Hydrostatic tests do not permit any visible leakage or drop in pressure. 2) C. NFPA 13 section 9.3.9.3 requires that access be provided for all sprinklers installed to protect ducts. This can be found in chapter 26 as well. Since NFPA provides minimum standards to provide reasonable protection, access is not required in the other concealed spaces as they are not required to be inspected per NFPA 25. 3) A. Section 28.3 was added to NFPA 13 in the 2019 edition and includes several new requirements for remote and automated inspections. In order to utilize and benefit from the convenience of remote inspections, they must be as effective as an inspector visually inspecting the system in person. 4) B & D. Section 28.2.5.2 specifically requires the “system demand, including hose steam allowance where applicable” as the required components to determine the minimum flow rate for testing. When determining which of the choices above is always required, system demand is apparent, but only the inside hose is always considered. Outside hose would only be considered if the backflow preventer is installed on a private fire main upstream of a fire hydrant. n
