SECTION 7 –
PLUMBING
18. 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.
19. Empty the Water Pump strainer to avoid water
freezing and cracking the filter bowl. See
“Water Pump” previously in this section.
Dump and Clean Holding Tanks
20. 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 sewage drain outlet and hose.
21. Flush the sewage tank using the Black Waste
Tank Flush Inlet.
22. 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.
Antifreeze Fill Procedure
(Fill plumbing lines with RV water system
antifreeze)
NOTE: Winterize tanks and waterlines 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. This feature is located near the water
pump.
Remove Water Filters
1. Remove and discard the filter cartridge from
the filtered cold water faucet/ice maker filter
assembly located below the galley sink.
•
Twist the filter cartridge “counter-clockwise”
about a quarter-turn and pull it down and out
of the filter socket.
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.
