SECTION 8-PLUMBING SYSTEMS JAYCO TOWABLE
There are two methods of winterizing your recreation vehicle based upon your model.
Please read, and understand the following instructions before beginning.
Air Pressure Method:
This method will utilize an air hose to blow excess water from the water lines.
NOTE: Recommended pressure is 40 PSI maximum. Exceeding this pressure may
rupture water line couplings and void your warranty.
1. Make sure all holding tanks are empty and all drain valves are OPEN.
2. Run the water pump until it is dry, this will take approximately 15-20 seconds.
3. OPEN all faucets and drains, including outside shower faucets (if so equipped) and
hold the flush lever open on the toilet.
Residential Refrigerator (if so equipped): Remove the refrigerator water filter (if so
equipped), discard it. (Install a new filter in the spring) Open the refrigerator low
point drain and drain water out of the refrigerator lines. Unplug the refrigerator. Prop
open the refrigerator doors to prevent odors from developing.
RV style Refrigerator (if so equipped): Unplug the refrigerator and prop open the
doors to prevent odors from developing.
4. Set the valves to the CITY WATER setting. Attach a blowout plug to the City Water
Fill inlet. Attach air hose to the blow out plug and blow air into the system. Any
remaining water should blow out in five to ten minutes. Recommended pressure is 40
PSI maximum.
Washing Machine (if so equipped): Set control to Quick Wash, temperature set to
WARM. Turn washer on until water is out of the lines. Press Pause then Stop/Cancel.
Add about a quart of antifreeze into the tub. Set control to Drain/Spin setting and let
run for about 1 minute. Antifreeze should go down into the machine pump. Press
Stop/Cancel, unplug it and wipe out any excess antifreeze.
5. Pour one cup of non-toxic RV antifreeze into any/all drain P-traps. (bathtub, sinks and
toilet).
Winterizing with Antifreeze Method:
It may be easier to winterize the RV with another person to assist you.
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 switches: Electric & LP Gas) Water heater
should never be drained when HOT or under pressure.
2. Level the RV and drain the fresh water plumbing system. (See Draining the Fresh
Water System)
3. Replace the water filter cartridge with the clear plastic bypass hose (if so equipped).
On full system canister water filters (if so equipped), remove the canister, take out the
filter, and reattach the empty canister.
Residential Refrigerator: Antifreeze should be kept out of the refrigerator. Remove
the refrigerator water filter and discard. Replace with a new one in the spring.
