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 PROCEDURE
You can winterize the water and plumbing
system of your coach using the following
method.
Blow Out Procedure
(Drain and purge waterlines using
compressed air)
1.
Level the Motor Home.
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.
Open Faucets.
Turn on the water pump and
open all sink faucets and shower head knobs.
Leave open after water stops flowing.
4.
Drain Toilet.
Press the toilet flush pedal and
hold until water stops flowing in the toilet.
Then turn water pump switch off.
5.
Drain Water Heater.
Turn off the water
heater power switch before draining the water
heater tank to avoid damage to the heating
element. Drain the water heater by removing
the plug from the base of the water heater tank,
accessible from the outside of the coach.
(Requires socket and ratchet).
•
Also, open the Pressure-Temperature Relief
valve at the top right portion of the tank to
prevent air locking in the tank while draining.
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.
