Set Up Winterization Valves
2. Turn water heater bypass valve to BYPASS
position.
3. Remove and save the protective cap from the
end of the antifreeze siphon tube.
4. Insert the end of the antifreeze siphon tube
into a pail or other container with 2 to 3
gallons of non-toxic RV antifreeze solution.
5. Turn the winterization valve handle so that it
points toward the siphon tube.
Fill Lines
6. Turn the water pump switch on.
7. 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. Press the toilet flush pedal 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 so it points
toward the waterline to the pump. This will
stop the flow from the suction tube and revert
the tank line flow to the 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 Water Heater
12. Turn off the Water Heater power switch
before draining the water heater tank to avoid
damage to the heating element.
13. Drain the water heater by removing the plug
from the base of the water heater tank,
accessible from the outside of the coach.
(Requires socket and ratchet).
14. Open the Pressure-Temperature Relief Valve
at the top right portion of the tank to prevent
air locking in the tank while draining.
15. Reinstall the water heater drain plug and close
the P-T relief valve when drained.
