6. Connect an air hose with regulator to the city/fresh water fill
connection, with valve positioned for city water. Set regulator for 40
PSI and turn on air. (Air adapters for winterizing are available at
RV supply locations.)
7. When water stops coming out of the drain valves, open and close
the faucets one at a time hot and cold, until only air comes out.
Don't forget the toilet and any outside faucets.
8. Hold the toilet flush mechanism open until the water has stopped
running.
9. Disconnect the air hose with adapter and turn the city/fresh water
valve to the tank fill position.
10. Close all valves, faucets and replace plugs.
11. One (1) gallon of FDA approved RV antifreeze is needed to protect
various water drain lines in the Motorhome. Pour 1 pint into both
the kitchen and bath shower drains. Pour 2 pints into the bath sink
drain. This will protect the P-traps, with some of the antifreeze
going into gray tank to protect the drain valve. Open the valve on
the toilet. Pour another 3 pints into the toilet, letting the antifreeze
run into the black tank to protect the drain valve located there. Use
a soft cloth to wipe out the sinks, shower and toilet (after the
antifreeze is poured in) to protect the surfaces from stains. Pour the
last pint into the washer/dryer drain.
WARNING: When draining the low-point drain lines and the water
heater ensure the water is not hot. Hot water from the lines can scald
causing burn injuries.
