Modern RVs offer a great outdoor experience thanks to their versatility and unrivaled comfort. However, comfort is directly related to the efficiency of the plumbing system and water heater, which ensure fresh water and hot showers. Keeping the heater in good condition is especially vital not only for comfort but also for overall safety. From this perspective, valves and fittings are important parts. The heater is connected to the plumbing system through a series of hoses, and valves and fittings provide the proper circulation of the water. Besides, they ensure safety whenever gases or pressurized fluids are involved.

Common components include pressure relief valves, outlet pipes, drain plugs, and drain valves, among others. Special parts include winterizing by-pass valves and heat traps. When you park your RV for the cold season, winterizing is a crucial operation to prevent moisture and bad smell during the following RVing season. Heat traps are helpful components designed to prevent heat loss through the inlet and outlet when the flow stops. We offer top-notch RV water heater valves and fittings made by top-ranked companies in the industry to ensure high performance for years to come.
