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.
10.
Let air flow for five minutes until water is completely drained out of faucets and drain valves. Then close
faucets one at a time.
11.
Operate and hold toilet flush lever until water is completely drained from toilet.
12.
Now turn air pressure off and disconnect water purge adapters. Recap the city water connection to avoid
contamination by dirt or insects.
13.
Close all drain valves and faucets to avoid contamination by dirt or insects. Reinstall water heater drain
plug and close P-T relief valve.
14.
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.
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 toilet since the flush valve will be closed.
Do not add automotive antifreeze or caustic chemicals such as bleach or laundry detergents into the toilet
bowl or holding tanks. Although these products may have a deodorizing 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
nontoxic RV antifreeze through the system. This product is available from your dealer and from most RV
supply stores. Follow directions on the container to determine the correct amount to use for your coach. See
“Water System Winterization Valve” on page 7-4 for instructions on filling water lines with RV antifreeze.
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.
19.
Close all windows and roof vents. Protect all appliance vent openings from contamination by animals or
insects (e.g. bird nests, wasp nests, etc.)
20.
Lubricate all door hinges and locks.
