SECTION 7 –
PLUMBING
Follow directions on the container to
determine the correct amount to use for
your motorhome.
Your motorhome is equipped with a manually
operated waterline winterization system for your
convenience in winterizing fresh waterlines.
The system features a Winterization (diverter)
valve with an antifreeze siphon 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.
Leave Water Heater Bypass valve in
NORMAL FLOW position if draining water and
blowing out waterlines. Place in BYPASS
position ONLY when using antifreeze solution in
waterlines.
WARNING
NEVER use automotive antifreeze/
coolant in your RV water system.
Automotive coolant/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 (to avoid filling water heater with
antifreeze).
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.)
3. Insert the end of the siphon tube into a pail or
container with 2 to 3 gallons of non-toxic RV
antifreeze solution.
4. Turn the Winterization valve handle so that it
points toward the siphon tube.
See "Water System Drain Valve Locations"
7-10
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.
Fill Lines
5. Turn the Water Pump switch ON.
6. Open each hot and cold water faucet handle/
knob in the motorhome – one at a time each in
turn until antifreeze solution just begins to
flow from the faucet, then close.
7. 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
8. Turn Water Pump switch OFF.
9. Turn the Winterization valve so it points
toward the waterline connected to the water
pump.
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 or
debris when not in use.
Drain Water Heater
11. Turn off the Water Heater power switch
before draining the water heater tank to avoid
damage to the heating element.
12. Drain the water heater by removing the plug
from the base of the water heater tank,
accessible from the outside of the motorhome
(requires socket and ratchet).
