8. Drain Optional Appliances. At this time, if
your coach is equipped with an optional
refrigerator ice maker, dishwasher, or washer/
dryer, the waterlines for these appliances must
also be drained.
(See "Winterizing Optional Appliances"
instructions at the end of this section.)
If not, proceed to the next numbered step.
9. Drain Water Heater. Turn off the Water
Heater power switch before draining the water
heater tank to avoid damage to the heating
element. Drain the water heater by removing
the plug from the base of the water heater tank,
accessible from the outside of the coach.
(Requires socket and ratchet).

• Also, open the Pressure-Temperature Relief
valve at the top right portion of the tank to
prevent air locking in the tank while draining.

10. Connect Air Pressure. After water has
stopped draining at all faucets and drain
valves, leave faucets open and connect a
"blow-out" plug to the city water connection
on the coach. Then use a compressed air hose
regulated to 30 psi or less to force air through
the system. A blow-out plug can be purchased

NOTICE
Limit air pressure to 30 psi to avoid
damage to equipment.
NOTE: DO NOT burst air into the system. This
can damage the water pump. It is better
to let air in slowly.
11. Let air flow for five minutes until water is
completely drained out of faucets and drain
valves. Then close faucets one at a time.
12. Drain Toilet. Operate and hold toilet flush
lever (or electric wall switch, if your coach is
equipped with an electric flush toilet) until
water is completely drained from toilet.
13. Turn air pressure off. Disconnect water
purge adapters. Recap the city water inlet to
avoid contamination by dirt or insects.

any water trapped during blow-out procedure.
Remount empty canister onto filter assembly.
(If not equipped with a full-coach water filter
system, continue to next numbered step).
15. Close all waterline and tank drain valves and
all faucets to avoid contamination by dirt,
insects, or rodents.
