Section 8: Plumbing System
™ Appliances must be winterized. Refer to the manufacturer's manual for pos-
sible additional information or contact Customer Service for assistance.
™ NOTE: The water heater must be drained to prevent damage from freezing.
Do not drain the water heater while it is hot or under pressure! The water
heater MUST BE BYPASSED DURING THE WINTERIZATION PRO-
CESS when introducing RV antifreeze into the plumbing system. Antifreeze
should be kept out of the water heater.
™ A tankless type water heater requires antifreeze in the water heater lines. Do
NOT bypass tankless water heater lines.
™ NOTE: The preferred method to winterize your recreation vehicle is by us-
ing RV antifreeze in the plumbing system. It may be easier to winterize the
RV with another person to assist you.
Winterize with Antifreeze Method
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. Use only RV
antifreeze.
This method requires non-toxic RV antifreeze in the water lines and does not require any
special tools. Use ONLY RV ANTIFREEZE in your fresh water system for freeze protec-
tion. No other product or commodity should be used. Antifreeze should never enter the
water heater, RV water filter, refrigerator, refrigerator water filter, 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). THE WATER HEATER SHOULD NEVER BE DRAINED
WHEN HOT OR UNDER PRESSURE.
Level the RV and drain the fresh water plumbing system. Refer to Draining the Fresh
2.
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 (Fig 1).
5.
Water Filter preparation:
Full System Canister water filter (if so equipped): Remove the canister, take
the filter out of the canister, then reattach the empty canister.
Bypass the cartridge water filter (if so equipped): Use the clear plastic tube
(supplied with RV) to bypass the water filter.
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 fixtures (pump only runs when a faucet or
fixture is open).
™ NOTE: When set to WINTERIZE: antifreeze will not enter the water heater
or the fresh water tank. There are no dedicated water heater bypass valves.
