4� Close all other drain valves.
5� Make sure the water heater bypass valve is set to
its open position, see Figure 8.1 �
6� 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).
7� Uncoil the hose attached to the kit, remove the
hose cap, and insert the hose down to the bottom
of the RV antifreeze container.
8� 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.
9� 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 shower head. Any
remaining antifreeze can be dumped down a drain.
10� Shut the pump OFF once all the lines are full.
11� Open all the faucets and leave them open.
12� 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.
CAUTION
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
will dilute the antifreeze.
