SECTION 7 -
PLUMBING
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. (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 antifreeze siphon tube
into a pail or other container with 2 to 3
gallons of non-toxic RV antifreeze solution.
4. Turn the Winterization valve handle so that it
points toward the antifreeze siphon tube. (See
"Water System Drain Valve Locations" chart
at the end of this section for location on your
model).
(Located in water service center)
NOTE: Ensure that all drain valves are
CLOSED before pumping RV antifreeze
into the water system.
Refer to the "Water System Drain Valve
7-14
Locations" chart at the end of this
section for valve locations on your
model.

5. Turn the Water Pump switch ON.
6. Open each hot and cold water faucet handle in
the motorhome - one at a time, until antifreeze
solution just begins to flow from the faucet,
then close.
7. Press the toilet flush lever 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 the Water Pump switch OFF.
9. Turn the Winterization valve 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.
10. Replace the protective cap onto the end of the
antifreeze siphon tube to keep out insects and
debris when not in use.
11. Close all waterline drains, tank drain valves,
and all faucets excluding the manifold hot and
cold low point drains. Due to the fact these are
the lowest points in the system, they must
remain open to allow migrated water to drain
out of the system until the system is ready to
be placed 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 motorhome
(requires socket and ratchet).
