If the motorhome is stored where freezing temperatures may occur, drain
the domestic fresh water loop completely of water. The method chosen to
winterize the motorhome and water lines is up to the motorhome owner. The
lines can be air blown to remove standing water or the lines can be filled
with an approved FDA RV antifreeze. Either way, all interior and exterior
faucets need to be opened and closed, one at a time, to be checked. All low
point drains should be opened and the holding tanks emptied.
NOTE: Ice makers (if applicable), water filters, washer/dryer
(if applicable) and water heaters all use domestic water and
should be drained and stored in accordance with the
manufacturer’s recommendation for winterization.
To use air pressure to winterize the motorhome you will need access to an
air compressor and an adapter to connect the air line to the water system.
Adapters can be found at any RV supply store. When hooked to the water lines
the pressure should not exceed 40 psi. Higher pressure can damage the lines.
1. Remove water faucet filter cartridge and replace filter with
diverter hose (see FAUCET WATER FILTER). Diverter hose
comes with motorhome and will be stored inside. With diverter
hose installed it creates a bypass in the water lines.
2. Drain the fresh water tank and lines by opening the tank drain
valve and the low point drain valves located in the outside water
control service compartment of the motorhome.
3. Let all water drain. Turn the pump on and allow it to run so that
all the water is cleared out of the pump and water tank. Turn the
pump off. Close the water tank shut off valve.
4. Remove water heater drain plug and open pressure release valve
located in the outside water heater access compartment.
5. After the water is drained, hook an air hose to the city water
connection located on the water control panel in the outside
service compartment and turn the air on. Do not exceed 40 psi in
the water lines and faucets.
6. When no further water can be seen coming out of the drains, move
water heater bypass valve to BYPASS setting located next to
water heater. Replace the water heater drain plug and close the
pressure release valve. Open all faucets (including the outside
spigot) one at a time to clear water from the faucet supply lines.
Do not forget to drain the shower.
7. If applicable, winterize the washer/dryer (See Winterizing the
Washer/Dyer).
