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 drained of water. See How to Winterize Your RV in 7 Easy Steps for complete RV
winterizing instructions - with pictures!
Being prepared and having the right equipment for your RV is essential. From water heater bypass
systems to water filters for the shower, it is always crucial to have
all the necessary equipment and supplies."
