SECTION 7 –
PLUMBING
WATER HEATER BYPASS
VALVE
Your coach is equipped with a water heater
bypass valve (located beneath the driver side
dinette seat) for easier winterization of waterlines
using RV antifreeze.
Turn the handle as shown to either “Bypass”
or “Normal Flow” through the water heater.
WINTERIZING PROCEDURE
Certain areas of your water system require
additional attention and disconnecting or
blowing out these lines may be required. Be sure
all water is drained from the system.
Step 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 of drain valves on your
model).
3.
Drain Exterior Shower/Wash Station.
Attach exterior shower hose, then point
shower hose toward ground and squeeze
handle 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.
4a.
If Equipped with 3M Cold Water Filter:
Remove and discard the filter cartridge from
the filtered cold water faucet filter assembly
located below the galley sink.
• Place a container beneath the filter to catch
any water that may drain from the waterline
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. Discard
used filter.
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.
