5. 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.)
6. When water stops flowing from the drain valves,
open and close the faucets one at a time, hot and
cold, until only air comes out. Do not forget the
toilet and any outside faucets.
7. Hold the toilet flush mechanism open until the
water has stopped running.
8. Disconnect the air hose with adapter and turn the
city/fresh water valve to the tank fill position.
9. Close all valves, faucets and replace plugs.
10. 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 grey tank to protect the drain valve.
Open the valve on the toilet. Pour anoth-
er 3 pints into the toilet, letting the
antifreeze run into the black tank to pro-
tect the drain valve. Use a soft cloth to
wipe out the sinks, shower and toilet
(after the antifreeze is poured in) to pro-
tect the surfaces from stains. Pour the last
pint into the washer/dryer drain.
WARNING:
Ensure the water is not hot when draining the low-point drain lines. Hot water from
the lines can cause burn injuries.
