SECTION 7 -
PLUMBING
The system features a diverter valve with
suction tube to draw non-toxic RV water system
antifreeze into the waterlines. There is also a
water heater bypass valve to avoid filling the
water heater with antifreeze. This feature is
located near the water pump in the water center
or utility compartment.
Leave bypass valve handle in NORMAL
FLOW position if draining water and blowing
out waterlines. Place in BYPASS position ONLY
when using antifreeze in waterlines.
WARNING
Never use automotive antifreeze/coolant
in your RV water system. Auto antifreeze
contains ethylene glycol which, if
ingested, can cause blindness and can
be fatal.
Set Up Winterization Valves
1. Turn water heater bypass valve to BYPASS
position.
2. Remove and save the protective cap from the
end of the antifreeze draw tube.
3. Insert the end of the draw tube into a pail or
other container with 2 to 3 gallons of non-
toxic RV antifreeze solution.

6. Open each hot and cold water faucet handle in
the coach, one at a time, until antifreeze
solution just begins to flow from the faucet,
then close.
Do not forget the exterior shower/wash station
knobs (if equipped).

8. Turn water pump switch off.
9. Turn the diverter valve handle so it points
toward the waterline to the pump (as shown in
previous photo. This will stop the flow from
the suction tube and revert the tank line flow
to the pump.
10. Replace the protective cap onto the end of the
suction tube to keep out insects and debris
when not in use.
