Winterizing And Storage - Airstream 2013 International Owner's Manual

Water Heater Draining
All models have a drain plug or petcock on the water heater. Access is from the
exterior. The plug or valve is usually located in the lower left corner, viewed as
you face the exterior of the water heater.
TOILET SHUTOFF VALVE
Your Airstream has one other water shutoff valve. It is located behind the toilet
and used to shut water off to the toilet in an emergency or service situation.

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 TRAPS AND TANKS,
THE WATER HEATER AND THE BATTERIES.
To completely winterize your trailer follow this procedure.
1. Level the trailer from side to side and front to rear. Open all faucets.
2. Replace the galley faucet filter with the bypass pipe. Store filter in a warm
place.
3. Turn the water pump switch to the ON position to expel water from the
storage tank
4. Open all drain valves including drain plug or valve on water heater and
exterior water service valve. (See drain valves on previous page)
5. While the water is draining from the system, open and flush the toilet-flushing
valve. Depress hand spray lever 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.
6. Turn the pump switch OFF after all water has been removed from the storage
tank.
7. Remove exhaust hose from water pump.
8. 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.
9. Lower the front of the trailer as far as the jack will allow until water ceases
