WATER HEATER BYPASS
WINTERIZATION VALVE
Your coach may be equipped with a water
heater bypass valve for easier winterization of
water lines using RV antifreeze. See Water
System Drain Valve Locations chart at the end of
this section for valve location on your model.
Turn the handle as shown to either Bypass or
Normal flow through the water heater.
WINTERIZING PROCEDURES
You can winterize the water and plumbing
system of your coach using one of the following
two methods – 1) Blow out water lines using
compressed air or – 2) Fill water lines with RV
water system antifreeze.
Method 1 – Blow Out Procedure
(Drain and purge water lines using
compressed air)
1.
Level the Motor Home.
If the coach is not
level, there may be ‘low points’ in water lines
that can trap water in the lines and prevent it
from draining properly.
2.
Drain Fresh Water Tank and Water Lines.
Open all water line drain valves and drain
fresh water tank. (See “Water System Drain
Valve Locations” chart at end of this section
for locations of drain valves on your model.)
3.
Drain Exterior Shower/Wash Station.
Open exterior shower knobs and lay shower
head on ground as shown to drain any water
left in the shower line. Also place the tip of
your finger into the city water inlet and gently
press the backflow valve ‘button’ in the center
of the inlet to drain any water trapped in the
inlet line.
4.
Remove the Water Filter Cartridge (if
equipped).
Remove the filter cartridge from
the filter assembly below the galley sink.
CAUTION
Leave bypass valve handle in NORMAL
FLOW position if draining water and
blowing out water lines. Place in BYPASS
position ONLY when using antifreeze
solution in water lines.
