SECTION 7 –
PLUMBING
7-10
water system antifreeze through the
plumbing system.
This product is available from your
dealer and from most RV supply stores
and national retail outlets.
Follow directions on the container to
determine the correct amount to use for
your coach.
Your coach is equipped with a manually
operated waterline winterization system for your
convenience in winterizing fresh waterlines.
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 solution in waterlines.
Set Up Winterization Valves
1. Turn water heater bypass valve to BYPASS
position. (See “Water System Drain Valve
Locations” chart at 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 tube
into a pail or other container with 2 to 3
gallons of non-toxic RV antifreeze solution.
3.
4. Turn the Winterization Valve handle so that it
points toward the siphon tube. (See “Water
System Drain Valve Locations” chart at end of
this section for location of winterization valve
on your model.)

5. Turn the water pump switch on.
6. 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.
Don’t forget exterior shower/wash station
knobs (if equipped.)
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 handle so it
points toward the waterline to the pump as
shown in the photo. This will stop the flow
from the antifreeze siphon tube and revert the
tank line flow to the pump.
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.
