Section 8: Plumbing System
The preferred method to winterize your recreation vehicle is by using RV antifreeze in the
plumbing system. It may be easier to winterize the RV with another person to assist you.
Winterize with Antifreeze 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 protection.
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 & LP gas switches inside the RV for stor-
age type water heater).
The water heater should never be drained when HOT or
under pressure.
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 motorhome has a standard storage type water heater you must remove the drain
plug to drain the water heater
(Fig 1).
5.
Replace the water filter cartridge with the plastic bypass hose.
6.
On full system canister water filters (if so equipped), remove the canister, take out the
filter, and reattach the empty canister.
If your RV is equipped with a residential style refrigerator, winterizing instruction
sheet (0311859 Whirlpool) may be included in your Warranty Packet.
7. Make sure the “fresh water tank drain” and “low point drains” are
closed.
This includes
the refrigerator/washer low point drains (if equipped).
If the recreation vehicle is going to be stored in a non-temperature controlled
environment with a risk of temperatures reaching 32°F (0°C) or lower, the air
pressure method is not adequate, winterizing with RV antifreeze
must
be used
in the plumbing system. Repairs due to freezing are not covered under the
terms of the
Towable Limited Warranty
.
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.
NOTE:
Appliances (refrigerator, dishwasher or clothes washer)
must be winterized. Refer to the appliance owner’s manual for
possible additional information or contact your Dealer or Customer
Service for assistance.
