SECTION 7 –
PLUMBING
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.
Remove Water Filters (if equipped)
Before pumping RV antifreeze into water
system, remove water filter cartridges (if
equipped.)
1. Remove and discard the filter cartridge from
the filtered water faucet assembly (if
equipped) below the galley sink.
(If your coach is not equipped with a filtered
water faucet, proceed to the next numbered
step.)
Water Filter Assembly below Galley Sink
• Twist the filter cartridge counter-clockwise
(left) about a quarter-turn and pull it down and
out of the filter socket.
NOTE: The water filter head has a built-in
bypass. No separate diverter plug is
needed.
2. Remove the filter canister from the full-coach
water filtration system in the water center
compartment (if equipped) and discard the
filter cartridge.
(If your coach is not equipped with a full-
coach water filtration system, proceed to the
7-12
next numbered step.)
After removing filter, remount the empty
canister onto the filter assembly and continue
the antifreeze fill procedure.
Set Up Winterization Valves
3. Turn Winterization Valve 1 to "Water Heater
Bypass" position to avoid filling water heater
with antifreeze.
See Water System Drain Valve chart at the end
of this section for location on your coach
4. Place handle of Winterization Valve 2 in the
"Winterize" position.
See Water System Drain Valve chart at the end

5. Remove and save the protective cap from the
end of the antifreeze siphon tube (which
connects to Winterization Valve 2). Insert the
end of the siphon tube into a pail or other
container with 2 to 3 gallons of non-toxic RV
antifreeze solution.
