10� After the water has stopped running from the drain
lines, apply at least 60 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 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.
11� 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.
12� 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.
13� If so equipped, remove the cartridge of the water
purifier and leave the purifier valve in the open
position.
14� 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�
15� Remove any items (food, cosmetics, etc.) from
trailer interior that might be damaged by freezing,
or that might damage the trailer if containers
should break.
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.
For additional winterizing protection, add a non-toxic
antifreeze (approved for drinking water system) to the
water lines using the following procedure:
1� Reconnect all lines except the hose to the pump
inlet port. Close all drain valves.
2� Turn water heater bypass valve on while turning
the other two valves to the off position. See photo
below for valves being referred to.
3� Replace the galley faucet filter with the bypass pipe
(refer to Galley Faucet Filter in Section 5 - Interior).
Store filter in a warm place.
4� Attach a length of hose to the pump inlet port. This
piece of hose should be long enough for the free
end to be inserted into and reach the bottom of the
antifreeze container.
5� For antifreeze usages follow manufacturer’s
instructions found on label of container.
6� Open all water faucets.
7� Insert hose length into the antifreeze container,
turn the pump switch on, and run the water pump
until the antifreeze solution fills all water lines.
Flush toilet. Work hand shower spray while holding
down in tub.
8� Shut off the pump and close all faucets.
9� Disconnect the hose length from pump inlet fitting
and reconnect water system inlet line.
