WINTERIZING AND STORAGE
When storing your trailer for short or long periods use the same precautions
as you would in your own home in regard to perishables, ventilation and rain
protection. In addition, for prolonged storage periods flush out all the drain
lines and the holding tanks. Also drain the entire water system including the
water heater and the water storage tank. Instructions for draining the water
system are explained in the following paragraphs on winterizing.
THE MAIN CONSIDERATION IN WINTERIZING IS TO GUARD AGAINST
FREEZING DAMAGE TO THE FRESH WATER SYSTEM LINES, TANK, AND
PUMP; THE WASTE DRAIN SYSTEM INCLUDING THE P-TRAPS AND TANKS,
THE WATER HEATER AND THE BATTERY.
To completely winterize your trailer follow this procedure.
1. Level the trailer from side to side and front to rear. Open all faucets.
2. Turn the water pump switch to the ON position to expel water from the fresh
water storage tank or open the tank drain valve. (See “To Empty Fresh Water
Tank” on previous page)
3. Open all fresh water line low point drain valves (See drain valves on previ-
ous page), the drain plug or valve on water heater, and the exterior shower
faucet. Remove and drain exterior shower hose.
4. While the water is draining from the system, open and flush the toilet-flushing
valve. Depress hand spray lever on toilet (if so equipped) while holding the
spray head down inside the bowl. Depress hand spray thumb button on the
telephone shower head while holding down inside the tub and drain all water
from the flexible hose. Unscrew the heads on both spray units and store.
5. Turn the pump switch OFF after all water has been removed from the storage
tank.
6. Remove outlet water line from the water pump.
7. Disconnect the water pump inlet connection and turn the pump on until all
the water is expelled. This water, about 1/2 cup, can be caught in a towel
or rag.
8. Lower the front of the trailer as far as the jack will allow until water ceases
to drain, then crank the jack up as high as it will go and let any remaining
water drain out.
9. After the water has stopped running from the drain lines, apply at least 60
lbs, of air pressure at the city water inlet. An air to city water adapter is
available from your dealer’s RV accessory store. Be sure the toilet valve and
all drain valves and faucets are open and pump outlet hose is disconnected.
This can be accomplished at a service station and will force any remaining
water from the water heater and remove any water which may be trapped
in low areas.
10. Pour a cup of *approved non-toxic RV antifreeze into the sinks and tub
drains to prevent P-trap freeze-up.
