PLUMBING
WATER HEATER BYPASS
VALVE
–If Equipped
Your coach may be equipped with a water
heater bypass valve for easier winterization of
waterlines 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.
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.
WINTERIZING PROCEDURES
You can winterize the water and plumbing
systems in your coach by using one of the
following two methods:
•
Blow out waterlines using compressed air,
or
•
Fill waterlines with RV water system
antifreeze.
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 the end of this
section for locations on your model).
3.
Drain Exterior Shower/Wash Station.
Open exterior shower knobs and lay shower
head on ground to drain any water left in the
shower line. Also, place the tip of your finger
into the Fresh Water Inlet and gently press the
backflow valve “button” in the center of the
inlet to drain any water trapped in the city
waterline.
4.
Remove the Water Filter Cartridge.
Remove and discard the filter cartridge from
the filtered cold water faucet/ice maker filter
assembly located below the galley sink.
