SECTION 7 –
PLUMBING
After removing filter, remount the empty
canister onto the filter assembly and continue
the antifreeze fill procedure.
3. Turn Winterization Valve 2 to the “Winterize”
position.
4. Remove and save the protective cap from the
end of the antifreeze siphon tube (which
connects to Winterization Valve 2). Insert the
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
5. Turn the Water Pump switch ON.
6. Open each hot and cold water faucet handle/
knob in the coach – 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 (if equipped).
7. Press the toilet flush pedal (or the “Normal
Flush” button on the wall control, if your
coach 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
8. Turn Water Pump switch OFF.
9. 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.
10. Replace the protective cap onto the end of the
antifreeze siphon tube to keep out insects and
debris when not in use.
Drain Appliances
11. At this time, if your coach is equipped with an
optional refrigerator ice maker, dishwasher, or
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
12. 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 coach during storage.
