Tips for 12V Hot Water System Repair and Maintenance A 12V hot water system is one of those appliances that can make life on the road feel like home. It’s a great investment that will ensure your comfort while travelling and living in your caravan, whether for hot and steamy shower or for washing dishes. With this in mind, you will want to make sure that it is always in good condition. After all, you wouldn’t want it to fail and ruin your trip. It also makes sense to know how it can be fixed when necessary. So, here are some tips for repair and maintenance: Regularly check the system for wearing and cracks Do this at least once a month. Pick a particular day, such as the first of every month to set a routine for inspections. Be on the lookout for wearing, cracks, and signs of leaks. It should only take a few minutes and it can save you from wasting money and water when it lets you deal with any minor problems before they worsen down the line. Leaks are often identified by black matter on the seals. Don’t wait until a costly disaster strikes Pump seals are likely to erode over time, causing leaks. If you find any leak in your 12V hot water system, you will have to replace them. Take the time to regularly clean and flush out the water heater. You can do this by mixing equal parts white vinegar and water, add it to the tank, and heat to the highest temperature before letting it cool down. Empty and rinse the tank with clean water. Keep water tanks clean Over time, a freshwater tank will accumulate dirt and bacteria. You can avoid that by flushing it out with a cleaning agent. Make sure it is completely empty before adding water and cleaning agent. Cover it and go for a drive to let the water move around, then drain and rinse. For tanks used for drinking water, use calcium hypochlorite or sodium to prevent water contamination. Check the power or gas supply If your 12V hot water system is not heating up, you may need to check on your gas or power supply. So, check if that is working. If it’s not, inspect the main regulator pressure, which should be 2.8kPa. If that’s good, there may be an obstruction in the pipe caused by insects or any other object. Using a jet of compressed air should remove that.
