PLUMBING

end of the siphon tube into a pail or other
container with 2 to 5 gallons of non-toxic RV
antifreeze solution.
.
NOTE: Ensure that all drain valves are
CLOSED before pumping RV antifreeze
into the water system.
Refer to the “Water System Drain Valve
Locations” chart at the end of this
section for valve locations on your
model.
Fill Lines
6. Turn the Water Pump switch on.
7. Open each hot and cold water faucet handle/
knob in the motorhome – one at a time each in
turn until antifreeze solution just begins to
flow from the faucet, then close.
Do not forget exterior shower/wash station
knobs.
8. Press the toilet flush pedal (or electric wall
switch, if your motorhome is equipped with
an electric flush toilet) and hold until
antifreeze begins flowing into the toilet.
Leave small amount of antifreeze that remains
in the bowl.
When Done Adding RV Antifreeze
9. Turn Water Pump switch off.
10. Turn the Winterization Valve 2 to “Normal”.
This will stop the flow from the antifreeze
siphon tube and revert the tank line flow to the
water pump.
11. Replace the protective cap onto the end of the
antifreeze siphon tube to keep out insects and
debris when not in use.
Drain Appliances
12. At this time, if your motorhome is equipped
with an optional washer/dryer, the waterlines
for these appliances must also be drained.
(See “Winterizing Optional Appliances”
instructions at the end of this section.)
If not equipped with optional appliances,
proceed to the next numbered step.
Fill Drainage System P-Traps
13. Pour about one cup of RV antifreeze down
each drain for the galley sink, lavatory sink,
and shower/tub. This fills the drain trap pipes
to prevent holding tank odors from entering
the motorhome during storage.
Dump and Clean Holding Tanks
14. Completely drain the sewage and waste water
holding tanks at an approved waste disposal
site. Drain the sewage tank first so the
following waste water can rinse any waste
solids from the sewage drain outlet and hose.
15. Flush the sewage tank using the Black Waste
Tank Flush Inlet.
16. Close waste tank drain valves and refit the
dust cap onto the sewage drain outlet.
This will inhibit rust formation on valve shafts
and prevent entry and contamination by
airborne debris, insects, and rodents.
Your drainage and fresh water systems are
now winterized.
See instructions for removal from storage in
Section 11 - Maintenance and Storage.
