SECTION 7 –
PLUMBING
Set Up Winterization Valves
1. Turn Water Heater Bypass valve to BYPASS
position. (See “Water System Drain Valve
Locations” chart at the end of this section for
location of bypass valve on your model).
2. Remove and save the protective cap from the
end of the antifreeze siphon tube (save cap to
cover tube after use). Insert the end of the
siphon tube into a pail or other container with
2 to 3 gallons of non-toxic RV antifreeze
solution.
3. Turn the Winterization Valve handle so that it
points toward the siphon tube. (See “Water
System Drain Valve Locations” chart at the
end of this section for location on your
model).
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.

4. Turn the Water Pump switch ON.
5. 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).
6. 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
7. Turn the Water Pump switch OFF.
8. Turn the Winterization Valve handle so it
points toward the waterline to the water pump.
This will stop the flow from the antifreeze
siphon tube and revert the tank line flow to the
water pump.
9. Replace the protective cap onto the end of the
antifreeze siphon tube to keep out insects or
debris when not in use.
Drain Water Heater
10. Turn off the Water Heater power switch
before draining the water heater tank to avoid
damage to the heating element.
• 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).
• Open the Pressure-Temperature Relief valve
at the top right portion of the tank to prevent
air locking in the tank while draining.
