It's recommend that RV'ers maintain their water heaters once a year, especially in areas where the water has a high mineral content. Unfortunately, many neglect this basic yet very important part of RV ownership and eventually suffer the consequences in poor operation and high maintenance costs. Fortunately, maintaining your RV's water heater isn't very difficult, but it does take a little forethought and planning.
To Drain the RV Water Heater
When not using RV water heater for long periods such as storing the RV during the winter months, the water heater should be drained to avoid damage from freezing during the winter and / or deterioration of tank life from mineral content in water supplies.
Water supplies sometimes contain high levels of sulphur, which causes an unpleasant smell, similar to rotten eggs. While unpleasant, the water is not harmful. Sanitizing the water system, as described earlier and allowing the sanitizing solution to remain for a few days, should eliminate the odor. Remember to thoroughly flush the system after sanitization. Adding a filtration system will help reduce such occurrences.
Weeping or Dripping As in residential water heaters, the water heater equipped in recreational vehicles contain a pressure relief valve that is designed to open if the temperature of the water within reaches 2 0 degrees F or if excessive pressure is built up. When pressure reaches 50 pounds, the relief valve will open and water will drip from the valve. The valve will close automatically once the pressure falls below 50 pounds. This dripping is normal and does not indicate a malfunctioning or defective valve.
Also, as water is heated it expands and with the closed water system in a recreational vehicle, water expansion will cause weeping at the pressure relief valve. One way to minimize this weeping is by maintaining an air pocket at the top of the water heater tank. The air pocket forms naturally by design but will reduce overtime through normal use.
