Water System Antifreeze
Procedure
NOTE: As an alternative to totally draining the
plumbing system, you may winterize
tanks and lines by pumping non-toxic RV
antifreeze through the system. This
product is available from your dealer and
from most RV supply stores. Follow
directions on the container to determine
the correct amount to use for your coach.
Your coach is equipped with a manually
operated water line winterization system for your
convenience in winterizing fresh water lines.
The system features a diverter valve with
suction tube to draw non-toxic RV water system
antifreeze into the water lines. 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.
•
Turn water heater by-pass valve to BY-PASS
position.
•
Remove and save the protective cap from the
end of the antifreeze draw tube.
•
Insert the end of the draw tube into a pail or
other container with 2 to 3 gallons of non-
toxic RV antifreeze solution.
•
Turn the diverter valve handle so that it points
toward the suction tube.
•
Turn the water pump switch on.
•
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.
When Done Adding RV Antifreeze:
•
Turn water pump switch off.
•
Turn the diverter valve handle so it points
toward the water line to the pump as shown in
the photo. This will stop the flow from the
suction tube and revert the tank line flow to
the pump.
CAUTION
Leave by-pass valve handle in NORMAL
FLOW position if draining water and
blowing out water lines. Place in BYPASS
position ONLY when using antifreeze
solution in water lines.
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.
