SECTION 7 –
PLUMBING
Your drainage and fresh water systems are now
totally winterized.
See instructions for removal from storage in
Section 11 - Maintenance and Storage.
Method 2 – Antifreeze Fill
Procedure
(Fill plumbing lines with RV water system
antifreeze)
NOTE: As an alternative to totally draining the
waterlines, you may winterize tanks and
lines by filling them with non-toxic RV
water system antifreeze through the
plumbing system.
This product 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 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. See the
Drain Valve Location chart at the end of this
section for locations on your coach.
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.
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)
1. Remove and discard the filter cartridge from
the filtered water faucet/ice maker filter
assembly (if equipped) below the galley sink.

water faucet or ice maker, proceed to the next
numbered step).
Water Filter Assembly
(Located 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.
