RV Water Heater Bypass Systems

The Water Heater Bypass is used when winterizing the water system. It is a series of valves or a single lever valve that allows the water flow to be shut off from the water heater and still be pumped to the rest of the hot water piping. This eliminates the need to fill the water heater tank with 6 gallons of winterizing antifreeze ... the tank is bypassed and then drainedof water.
