SECTION 7 –
PLUMBING
18. Turn on the Shower drain pump switch and
slowly pour 2 gallons of RV antifreeze into the
shower drain. Turn off pump switch when
done.
19. Open Black Waste Tank Drain valve.
20. Open Gray Waste Tank Drain valve.
21. Press and Hold the Waste Pump switch for
approximately 5-10 seconds to get antifreeze
into the pump.
22. Close Black and Gray Waste Tank Drain
valves.
Dump and Clean Holding Tanks
23. 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.
24. 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.
Step 2 – Antifreeze Fill Procedure
(Fill plumbing lines with RV water system
antifreeze)
NOTE: Non-Toxic RV water system antifreeze 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
7-18
waterlines. There is also a Water Heater Bypass
valve to avoid filling the water heater with
antifreeze.
Leave the Water Heater Bypass valve handle
in NORMAL FLOW position if draining water
and blowing out waterlines. Place in BYPASS
position ONLY when using antifreeze solution in
waterlines.
WA RNING
NEVER use automotive antifreeze/
coolant in your RV water system.
Automotive coolant/antifreeze contains
ethylene glycol which, if ingested, can
cause blindness and can be fatal.
Remove Water Filters
1a. If Equipped with 3M Cold Water Filter:
Remove and discard the filter cartridge from
the filtered cold water faucet filter assembly
located below the galley sink.
• Place a container beneath the filter to catch
any water remaining in the waterlines during
filter removal.
• Twist the filter cartridge counter-clockwise
(to the left) about one-quarter turn, then pull
it down and out of the filter socket.
• Install the diverter plug into the filter socket.
Insert plug up into the filter socket as far as
possible and twist clockwise (to the right)
one-quarter turn until it stops.
