SECTION 7 –
PLUMBING
7-8
engine must be running (such as when driving
down the road). This will prevent excessive
discharge of the house battery.
NOTE: The holding tank heater pads are
electrical resistant-type heating
elements. This type of heating element
typically uses a large amount of current
while operating. If the tank heaters are
used without a recharging source, they
will drain the house batteries in a
relatively short period. Typically, the
batteries would not support overnight
heating without a supplemental charging
source.
WATERLINE & TANK DRAIN
VALVES
The water drain valves are used to drain water
from the water tank and the water supply lines
when preparing the motorhome for storage or
when sanitizing the water system.
To open or close the drain valves, turn the
handles in the directions indicated by the
following illustration.
See the drain valve location chart at the end of
this section for locations on your model.
WATER HEATER BYPASS AND
ANTIFREEZE SIPHON VALVES
–If Equipped
Your motorhome may be 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 motorhome using one of the
following two methods – 1) Blow out waterlines
using compressed air or – 2) Fill waterlines with
RV water system antifreeze.

Drain Valve
(Typical)
•The Water Tank Drain Valve has on/off
indicator arrows.
•Rotate the shut-off valve “clockwise” to
turn valve OFF.
•Rotate the shut-off valve “counter-
clockwise” to turn valve ON.
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.
