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 HOT AND COLD WATER SYSTEMS, THE WASTE DRAIN SYSTEM
(INCLUDING THE TRAPS), AND THE WATER HOLDING TANKS, AND 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
storage tank
3. Open all drain valves including drain plug or valve on water heater and exterior
water service valve. (See drain valves on previous page)
4. 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 showerhead 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 exhaust hose from 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 lavatory, sink and tub
drains to prevent trap freeze-up.
*Approved and listed by a recognized testing authority such as UL (Underwriter Lab).
11. Be sure to open the waste holding tank drain valves and drain and flush the
tanks thoroughly (THIS IS VERY IMPORTANT AS THE SEWAGE IN THE TANKS, IF
FROZEN, COULD SERIOUSLY DAMAGE THE TANKS.)
