Cold Weather Storage
If the motorhome is stored where freezing
temperatures may occur, drain the domestic
fresh water loop. Begin draining the fresh water
tank by opening the low point drain for the fresh
tank and allowing the water to drain.
NOTE:
Icemakers, water filters, water heater
all use domestic water and should be
drained and stored in accordance with
the manufacturer’s recommendation for
winterization.
WINTERIZATION
Water, plumbing and sewer systems require
winterization when the motorhome is placed
in storage. The recommended method of
winterizing the motorhome is using air pressure
to remove liquids that may freeze and cause
damage to the various systems and appliances.
The lines can then be left empty or fi lled with an
FDA approved RV antifreeze. When plumbing
lines are drained, antifreeze is not necessary,
and the decision to use antifreeze is left to the
motorhome operator.
NOTE:
ONLY FDA approved RV antifreeze
should be used to winterize the water
systems in the motorhome.
Using Air Pressure
Access to an air compressor, and an adapter
to connect the air line regulator to the water
system, is necessary. Air adapters used for
winterizing are available at RV supply locations.
Air pressure should not exceed 40 PSI. Higher
pressure can damage the lines.
1. Empty and fl ush the holding tanks.
2. Drain the fresh water tank by opening
the fresh tank drain valve in the water
service center.
3. Open all low-point drain valves located
behind service center panel including
fresh tank drain. Let all the water
drain. If equipped with a LP-Gas water
heater, position the winterize valve to
by-pass. Remove drain plug to drain
tank.
4. Remove fi lter at kitchen sink and install
diverter hose.
CAUTION:
It is recommended that a qualified
RV service technician familiar with
motorhomes, such as an authorized
dealer, perform the winterizing
procedure.
5. Connect an air hose with regulator
to the City Water connection. Turn
the tank fi ll lever to the “City Water”
position. Set regulator for 40 psi
and turn on air. (Air adapters for
winterizing are available at RV supply
locations.)
6. When water stops fl owing 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 fl ush mechanism open
until the water has stopped running.
8. Disconnect the air hose with adapter
and turn the tank fi ll lever to the “Tank
Fill” position.
9. Close all valves and faucets.
10. If applicable winterize the washer/dryer
(see “Winterize the washer/dryer).
11. Use one (1) gallon of FDA approved
RV antifreeze 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
another 3 pints into the toilet, letting
the antifreeze run into the black tank to
protect the drain valve. 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.
