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 lever 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-
tem. This product is available from
your dealer and from most RV supply
Limit air pressure to 30 psi to avoid
damage to pump or water lines.
