Water System Winterizing
READ THIS BEFORE WINTERIZING YOUR WATER SYSTEM.
If your RV is going to be stored unheated in temperatures that
COULD GO BELOW FREEZING, the fresh water and waste
systems must be winterized. Follow this procedure:
•
Drain the fresh water tank.
•
Drain pipes by turning the water pump ON and opening
a cold water faucet.
•
Wait for the water flow to stop. Turn pump OFF. Leave
faucets OPEN.
•
Turn ON all faucets and OPEN the HOT and COLD
Water Pipe Drain Valves. Leave these valves in the
OPEN position. These valves are located either under
the galley sink or in an exterior compartment, and permit
the water to drain onto the ground below the RV.
•
Open the Water Heater drain valve located at the bottom
of the heater (or remove plug). Let the tank drain.
•
Open the heater Safety Valve.
•
Flush the toilet.
•
After each faucet has been opened, drained and closed,
Close the Water Line Drain Valves.
•
Drain the Waste Water Holding Tank.
•
Double check that ALL WATER has been drained.
•
Secure all protective caps including the water tank filler,
city water inlet and waste drain outlet.
CAUTION: DRAINING THE WATER SYSTEM ALONE MAY NOT
BE ENOUGH TO PROVIDE COMPLETE COLD WEATHER
PROTECTION FOR AN RV UNIT THAT WILL BE STORED IN AN
UNHEATED ENVIRONMENT WHERE TEMPERATURES DROP
BELOW FREEZING. CONSULT YOUR DEALER FOR MORE
INFORMATION ON THE BEST METHOD OF WINTERIZING
YOUR VEHICLE.
Units equipped with a winterization siphon hose should use it to
pump RV anti-freeze into the plumbing system. Always pour a
cupful of RV anti-freeze into each drain after your coach has been
winterized.
WARNING: DO NOT USE AUTOMOTIVE ANTI-FREEZE OR
WINDSHIELD WASHER FLUID ANTI-FREEZE IN THE RV
POTABLE WATER SYSTEM. THESE CAN BE HARMFUL OR
FATAL IF SWALLOWED. YOUR DEALER CAN PROVIDE YOU
WITH SPECIAL ANTI-FREEZE THAT IS SAFE AND APPROVED
FOR RV WATER SYSTEMS. ALWAYS FOLLOW
MANUFACTURER’S INSTRUCTIONS FOR THESE ADDITIVES
