STORING YOUR MOTOR HOME
City Water
Connection
CAUTION
Limit air pressure to 30 psi to avoid
damage to pump or water lines.
NOTE: DO NOT burst air into the system. This
can damage the water pump. It is better
to let air in slowly.
9. Let air flow for five minutes until water is
completely drained out of faucets and drain
valves. Then close faucets one at a time.
10. Operate and hold toilet flush lever until
water is completely drained from toilet.

11. Now turn air pressure off and disconnect
water purge adapters. Recap the city water
connection to avoid contamination by dirt or
insects.
12. Close all drain valves and faucets to avoid
contamination by dirt or insects. Reinstall
water heater drain plug and close P-T relief
valve.
13. 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.
14. Turn the shower sump pump on and pour 1/2
gallon of non-toxic RV antifreeze into the
shower drain. Turn the shower sump pump
off immediately after pouring antifreeze
remains in pump and lines.

WARNING
NEVER use automotive antifreeze/
coolant in your RV water system.
Auto antifreeze contains ethylene
glycol which, if ingested, can cause
blindness and can be fatal.
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 winterize
tanks and lines by pumping non-toxic RV
antifreeze through the system. This prod-
uct is available from your dealer and
from most RV supply stores. Follow di-
rections on the container to determine
the correct amount to use for your coach.
15. Place a bucket beneath the sewage drain
valve outlet and re-drain the sewage and
waste holding tanks of any clean water that
entered during "blow-out" procedure.
Close dump valves to prevent valve shafts
from rusting and to prevent entry by rodents
and insects. Refit the dust cap onto the drain
outlet.
Your drainage and fresh water systems are now
totally winterized.
16. Have the vehicle chassis completely serviced
and lubricated. Be sure radiator antifreeze
protection level is sufficient for the lowest
anticipated temperatures.
17. Wash and wax the coach.
18. Inspect all seams and seals around doors,
windows, vents, and any other joints.
Replace or repair any that are damaged.
Sealing materials and compounds can be
purchased from your dealer. Badly damaged
weather seals may need to be replaced by
your dealer.
