SECTION 7 –
PLUMBING
NOTICE
Limit air pressure to 30 psi to avoid
damage to equipment.
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. Drain Toilet. Operate and hold toilet flush
lever until water is completely drained from
toilet.
11. Turn air pressure off. Disconnect water
purge adapters. Recap the city water inlet to
avoid contamination by dirt or insects.
After Disconnecting Air Pressure
12. Close all waterline and tank drain valves, and
all faucets to avoid contamination by dirt,
insects, or rodents.
13. Reinstall the Water Heater drain plug and
close the Pressure-Temperature Relief valve.
14. 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.
15. Empty the water pump strainer filter bowl to
avoid water freezing and cracking the filter
bowl. See "Water Pump" previously in this
section.
7-14
Dump and Clean Holding Tanks
16. Completely drain the waste water holding
tanks at an approved waste disposal site.
Drain the sewage (black) tank first so the
following waste water can rinse any waste
solids from the dump outlet and sewage drain
hose.
17. Close waste tank drain valves and refit the
dust cap onto the sewage 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 winterized.
See instructions for removal from storage in
Section 11 - Maintenance and Storage.
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 Winterization (diverter)
valve with an antifreeze 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 water heater with
antifreeze.
