Section 8: Plumbing System
Winterizing with antifreeze
This method adds antifreeze to the water lines for freeze protection for temperatures 32°F
(0°C) and below. A second person will make this job easier.
1. Close all the faucets in the coach (including outside shower). Attach the shower hose
to the outside shower quick connector.
2. Close the fresh water tank drain and all other low point drains. Include the hot/cold
water line drain valves at the utility center (Fig. 2).
3. The City Water valve should be set to the vertical (city water) position (Fig. 1).
4. Water heater bypass valves should be set to the BYPASS position. Middle valve ON
and the two supply valves to the water heater OFF
5. Place the clear hose from the utility center (Fig. 2) into a container of RV antifreeze
(requires about 2 gallons). The clear hose is located at the utility center. The dashed
circle in (Fig 1) indicates an item behind the utility center panel.
6. Siphon valve should be turned so it is in-line with the clear plastic hose.
7. Turn the water pump ON (Fig. 1) and antifreeze will be drawn out of the container and
into the water lines as each fixture is opened in the motor home. To aid siphoning, place
the antifreeze container on a flat surface approximately 2 feet off the ground.
Winterizing the Macerator System (if so equipped)
Ensure that all tanks are empty.
1.
2. Pour RV antifreeze into the toilet and down into the black water tank. At time of print-
ing, quantity of antifreeze to be put into the black tanks was not determined. Check
with Customer Service for proper amount to use.
NOTE: Use a container (bucket) for
capturing system fluid!
3. Turn the macerator pump ON.
4. Run the pump until antifreeze begins to discharge from
the dump connector attached to the flex hose.
5. Turn the macerator pump OFF.
6. Drain the flex hose by holding it at a sloped angle to drain excess water and return the
hose to the storage location.
7. As an added safety measure, open and drain the Macerator Bypass Valve.
Completing the Winterizing with antifreeze
8. After all of the water lines/appliances have been winterized, turn the pump OFF and
disconnect the shower hose from the outside shower.
9. Turn the siphon valve so it points away from the clear hose (Fig 2). Valve is located
behind the large panel on the utility center.
10. Open the drain valve on the fresh water tank and leave it open.
11. Add a cup of antifreeze in all the drain p-traps.
12. Remove the clear hose from the container of RV antifreeze and clean.
NOTE: To reduce the chance of contamination, prevent the clear hose
from coming into contact with the ground or the water fittings.
