SECTION 7 –
PLUMBING

Your drainage and fresh water systems are
now 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 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 the Water Heater 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 cold water filter assembly below the galley
sink. (
If your coach is not equipped with
filtered cold water, proceed 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
(to the left) 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 (to the right)
one-quarter turn until it stops.
Set Up Winterization Valves
2. Turn the Water Heater Bypass valve to
BYPASS position. (See “Water System Drain
Valve Locations” chart at the end of this
section for location on your model).
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.
