SECTION 10

STORING YOUR MOTOR HOME

10. After water has stopped draining at all fau-

cets and drain valves, connect a “blow-out”

plug to the city water connection on the

coach. Then use a hand pump or air com-

pressor regulated to 30 psi or less to force air

through the system. (A “blow-out” plug can

be purchased at any Winnebago or Itasca

dealer. P/N 701705-01-000.)

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. Operate and hold toilet flush pedal until

water is completely drained from toilet.

13. Now turn air pressure off and disconnect

water purge adapters. Recap the city water

connection to avoid contamination by dirt or

insects.

14. Close all drain valves and faucets to avoid

contamination by dirt or insects. Reinstall

water heater drain plug and close P-T relief

valve.

15. Pour about one cup of non-toxic RV anti-

freeze into the kitchen sink drain, bathroom

sink drain and shower drain. This prevents

any holding tank odors from entering the

coach during storage.

It is not necessary to add antifreeze to the toi-

let since the flush valve will be closed.

Do not add automotive antifreeze or caustic

chemicals such as bleach or laundry deter-

gents into the toilet bowl or holding tanks.

Although these products may have a deodor-

izing effect, they may damage plastic and

rubber parts in the system.

NOTE: As an alternative to totally draining

the plumbing system, you may winter-

ize tanks and lines by pumping non-

toxic RV antifreeze through the sys-

Limit air pressure to 30 psi to avoid

damage to pump or water lines.
