WATER HEATER BYPASS AND
ANTIFREEZE SIPHON VALVES
Your coach is equipped with a Water Heater
Bypass valve and an Antifreeze Siphon
(Winterization) valve for winterizing waterlines
using RV antifreeze.
Turn the handle as shown to either bypass or
flow mode.
Refer to the “Water System Drain Valve
Locations” chart at the end of this section for
locations on your model.
WINTERIZING PROCEDURES
You can winterize the water and plumbing
system of your coach using one of the following
two methods – 1) Blow out waterlines using
compressed air or – 2) Fill waterlines with RV
water system antifreeze.
Further Information
Refer to the Water Heater manufacturer’s user
guide provided in your InfoCase for complete
winterizing procedures.
Method 1 – Blow Out Procedure
(Drain and purge waterlines using
compressed air)
1.
Level the Motorhome.
If the coach is not
level, there may be “low points” in waterlines
that can trap water in the lines and prevent it
from draining properly.
2.
Drain Fresh Water Tank and Waterlines.
Open all waterline 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 Cold Water Filter Cartridge (if
equipped).
Remove the filter cartridge from
the filter assembly below the galley sink.
(
If your coach is not equipped with a cold
water filter, continue to next numbered step.
)
• Place a container beneath the filter to catch
any water that may drain from the waterline
during filter removal.
CAUTION
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.
