Close holding tank drain valves, low point drain valves and
fresh water tank drain valve.
Pour approximately five gallons of approved non-toxic anti-
freeze into the fresh water tank.
Turn the water pump master switch ON.
Open each cold water faucet, run the water pump and let
about a cup of antifreeze solution flow continuously through
each faucet. Close each cold water faucet.
Flush the toilet until the antifreeze solution flows continu-
ously. Release flush mechanism.
Winterize the water heater according to the instructions
provided with the water heater operating manual. Winterize
the hot water lines by opening each hot water faucet, allowing
antifreeze solution to flow continuously, and then close each
faucet. This will require considerably more antifreeze solu-
tion, and you may choose to do this step before winterizing
the cold water lines so you can recycle the solution.
When filling the plumbing systems with antifreeze, be sure to
open and operate all fixtures and valves allowing the anti-
freeze solution to flow freely.
Pour one cup of antifreeze solution down each drain. (Tub!
shower, galley sink, bathroom sink, washer P-trap)
Install all protective caps:
Water tank fill
City water Inlet cap
Waste tank drain outlet cap

winterize the fresh water
system.
