7-11
SECTION 7 –
PLUMBING
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 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.
After Disconnecting Air Pressure
14. Empty the full-coach water filter canister of
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 step.
)
15. Close all waterline drains, tank drain valves,
and all faucets to avoid contamination by dirt,
insects, or rodents.
16. Reinstall the Water Heater drain plug and
close the P-T Relief Valve.
17. Pour about one cup of RV antifreeze down
each drain for the galley sink, lavatory sink,
and shower/tub. This fills the drain trap pipes
to prevent holding tank odors from entering
the coach during storage.
NOTE: 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.
18. Empty the water pump strainer filter bowl to
avoid water freezing and cracking the filter
bowl. See “Water Pump” previously in this
section.
Dump and Clean Holding Tanks
19. Completely drain the sewage and waste water
holding tanks at an approved waste disposal
site. Drain the sewage tank first so the
following waste water can rinse any waste
solids from the dump outlet and sewer hose.
20. Flush the sewage tank using the Black Waste
Tank Flush Inlet (if equipped).
21. Close dump valves and refit the dust cap onto
the drain outlet.
This will inhibit rust formation on valve shafts
and prevent entry and contamination by
airborne debris, insects, and rodents.
Your drainage and fresh water systems are now
totally winterized.
See instructions for removal from storage in
Maintenance Section.
Method 2 –
Antifreeze Fill Procedure
(Fill plumbing lines with RV water system
antifreeze)
NOTE: As an alternative to totally draining the
waterlines, you may winterize tanks and
lines by filling them with non-toxic RV
water system antifreeze through the
plumbing system.
This product is available from your
dealer and from most RV supply stores
and national retail outlets.
Follow directions on the container to
determine the correct amount to use for
your coach.
Your coach is equipped with a manually
operated waterline winterization system for your
convenience in winterizing fresh waterlines.
The system features a diverter valve with
siphon tube to draw non-toxic RV water system
antifreeze into the waterlines. There is also a
water heater bypass valve to avoid filling the
CAUTION
Limit air pressure to 30 psi to avoid
damage to pump or waterlines.
