SECTION 10
PLUMBING SYSTEMS
10-14
Winterization Valve
Your coach is equipped with a manually
operated water line winterization system for
your convenience in winterizing fresh water
lines.
The system features a diverter valve and suc-
tion tube in-line between the tank and water
pump to draw non-toxic RV water system anti-
freeze into the water lines. This feature is located
near the water pump and drain valves beneath
the rear bed.
To Fill Lines with RV Water Line Antifreeze
•
Turn water heater by-pass valve to BY-PASS
position.
•
Remove and save the protective cap from the
end of the suction tube.
•
Insert the end of the tube into a container of
RV antifreeze solution.
•
Turn the diverter valve handle so that it points
toward the suction tube.
•
Turn the water pump switch on.
•
Open each hot and cold water faucet handle
in the coach one at a time until antifreeze so-
lution just begins to flow from the faucet,
then close.
When Done Adding RV Antifreeze:
•
Turn water pump switch off.
•
Turn the diverter valve handle so it points to-
ward the water line to the pump as shown in
the photo. This will stop the flow from the
suction tube and revert the tank line flow to
the pump.
•
Replace the protective cap onto the end of the
suction tube to keep out insects and debris
when not in use.
