SECTION 7 –
PLUMBING
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 motorhome 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. Turn Water Heater Bypass valve to BYPASS
position (to avoid filling water heater with
antifreeze).
See “Water System Drain Valve
Locations” chart at the end of this section
for location of bypass valve on your model.
3. Remove and save the protective cap from the
end of the antifreeze siphon tube (save cap to
cover tube after use.)
4. Insert the end of the siphon tube into a pail or
container with 2 to 3 gallons of non-toxic RV
antifreeze solution.
5. 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.
NOTE: Ensure that all drain valves are
CLOSED before pumping RV antifreeze
into the water system.
Refer to the “Water System Drain Valve
Locations” chart at the end of this
section for valve locations on your
model.
Fill Lines
6. Turn the Water Pump switch ON.
7. Open each hot and cold water faucet handle/
knob in the motorhome – one at a time each in
turn until antifreeze solution just begins to
flow from the faucet, then close.
Do not forget exterior shower/wash station
knobs (if equipped).
WARNING
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.
