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 your trailer is to
guard against freeze 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� Turn the water pump switch to the ON position to
expel water from the storage tank
3� Open all drain valves including exterior water
service valve, if applicable�
4� While the water is draining from the system, open
and flush the toilet-flushing valve. 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� Disconnect outlet hose from water pump. Turn the
pump on until all the water is expelled. This water,
about 1/2 cup, can be caught in a towel or rag.
Reconnect hose�
7� 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 allow any
remaining water to drain out.
8� After the water has stopped running from the drain
lines, apply 50 lb� 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, all drain valves, and faucets are open
and the pump outlet hose is disconnected. This
can be done at a service station and will force any
remaining water from the water heater and remove
any water that may be trapped in low areas.
9� Pour a cup of non-toxic RV antifreeze that has
been approved and listed by a recognized testing
authority such as Underwriter Lab into the lavatory,
sink and tub drains to prevent trap freeze-up�
10� Be sure to open the waste-holding tank dump
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) � Plan
ahead and have this done at a dump station.
11� Remove the batteries from your trailer and store
in a cool, dry place where there is no danger of
freezing. It is very important for optimum life of a
battery to check it periodically and to keep it fully
charged�
CAUTION
Remove all RV antifreeze spillage from all drain
and faucet parts after winterizing. Failure to do so
could result in damage to the plumbing fixture’s
finish.
Optional; An additional step to winterization is to
consider adding a non-toxic RV antifreeze (approved
for drinking water systems) to the water lines using the
pre-installed Winterization Kit�
Before beginning, read the RV antifreeze
manufacturer’s label for instructions specific to the
antifreeze you plan to use. It may take 2-3 gallons to
fill the entire system so prepare accordingly. It will be
helpful to have another person watching and operating
the faucets and showerheads as you follow these
steps�
The Winterization Kit is near the water pump. See
Water Pump Access Locations in Section 8. For drain
valve locations see Drain Valve Locations in this
section�
1� Reconnect all lines and showerheads that were
disconnected in the previous steps�
2� Close all the drain valves�
3� Open the sink and shower drains if they are closed�
4� Open all the faucets, including the showerhead
faucet handle and, if equipped, the external
showerhead�
