This method requires non-toxic RV antifreeze in the water lines and does not require any
special tools. Use in your fresh water system for freeze protec-
tion. No other product or commodity should be used. Antifreeze should enter the
water heater, RV water lter, refrigerator, refrigerator water lter, or fresh water tank.
1. Turn water heater power OFF (both electric and LP gas switches inside the RV for stor-
age type water heater).
.
2. Level the RV and drain the fresh water plumbing system. Refer to Draining the Fresh
Water System.
3. Water heater should be empty after draining the plumbing system.
4. If your motor home has a standard storage type water heater you must remove the drain
plug to drain the water heater ().
5. Water Filter preparation:
Remove the canister, take
the lter out of the canister, then reattach the empty canister.
Use the clear plastic tube
(supplied with RV) to bypass the water lter.
6. Make sure the fresh water tank drain and low point drains are closed. This includes the
refrigerator/washer low point drains (if so equipped).
7. Set the water valves to WINTERIZE setting and connect
a hose to the City Water Inlet. Insert the other end of the
hose into a container of RV antifreeze. Turn the pump ON
with the pump switch. Antifreeze will be drawn into the
water lines and xtures (pump only runs when a faucet or
xture is open).
Automotive antifreeze (ethylene glycol) and windshield washer antifreeze
(methanol) are poisonous. Never use these products in your fresh water sys-
tem. These products are harmful and may be fatal if swallowed.
