SECTION 7 –
PLUMBING
Leave 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.
Remove Water Filters (if equipped)
1. Remove and discard the filter cartridge from
the filtered water faucet/ice maker filter
assembly (if equipped) below the galley sink.
(If your coach is not equipped with a filtered
water faucet or ice maker, proceed to the next
numbered step).
• Twist the filter cartridge “counter-clockwise”
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.
Set Up Winterization Valves
2. Turn Winterization Valve 1 to “Water Heater
Bypass” position to avoid filling water heater
with antifreeze.
.
3. Turn Winterization Valve 2 to the “Winterize”
position.
4. 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 5 gallons of non-toxic RV
antifreeze solution.
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.
