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.
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�
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,

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.

5� Go to the winterization kit and turn the valve handle
to the winterizing position as indicated on the tag
attached to the kit (shown above).
6� Uncoil the hose attached to the kit, remove the
hose cap, and insert the hose down to the bottom
of the RV antifreeze container.
7� Turn the pump switch on and run it until antifreeze
starts coming out of the faucets. Once antifreeze
runs from one tap, turn it off and continue to
the next one. Move from one fixture to the next,
shutting them off as you go until all the lines are
full. As you empty each antifreeze container, turn
the pump off, transition to a full container, and turn
the pump back on to continue.
8� Allow the antifreeze to flow down drains. Flush the
toilet and allow antifreeze to flow down the toilet.
If equipped, operate the toilet hand sprayer until
antifreeze is coming out. Work the hand shower
sprayer while holding it down in the tub until
antifreeze is coming out, and if equipped, do the
same with the external showerhead. Any remaining
antifreeze can be dumped down a drain.

10� Open all the faucets and leave them open.
11� Turn the winterization kit valve back to the normal
use position, place the cap back on the hose, and
coil it back up for storage.
Remove all RV antifreeze spillage from all drain
and faucet parts after winterizing. Failure to do so
could damage the plumbing fixture's finish. Do not
use water to rinse antifreeze down the drain as it
