SECTION 7 –
PLUMBING
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.
Leave Water Heater Bypass valve in
NORMAL FLOW position if draining water and
blowing out waterlines. Place in BYPASS
position ONLY when using antifreeze solution in
waterlines.
Remove Water Filter
1. Remove and discard the filter cartridge from
the cold water filter assembly below the galley
sink. (If your coach is not equipped with
filtered cold water, continue to next numbered
step).
• Place a container beneath the filter to catch
any water remaining in the waterlines during
filter removal.
• Twist the filter cartridge “counter-
clockwise” 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” one-quarter
turn until it stops.
Set Up Winterization Valves
2. Remove and save the protective cap from the
end of the antifreeze siphon tube (save cap to
cover tube after use.) Insert the end of the
siphon tube into a pail or other container with
2 to 3 gallons of non-toxic RV antifreeze
solution.
3. Turn the Winterization valve handle so that it
points toward the siphon tube. (See “Water
System Drain Valve Locations” chart at the
end of this section for location on your
model).
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.
