SECTION 7 –
PLUMBING
When using a sewer hook-up, keep the dump
valves closed until a tank becomes full or when
preparing to leave the site. This keeps the solids
in suspension, allowing them to be carried out
with the liquids when the dump valve is opened.
If the valve is left open, the liquids will drain off,
leaving solids in the tank. Should this
accidentally happen, disconnect the hose, fill the
tank about half full with water, and drive a few
miles to dislodge the solids. A few starts and
stops will aid in the process. Then reconnect the
hose and drain in the normal manner.
NOTE: Always keep sewage drain outlet capped
while sewage connection is not in use.
Holding Tank Level Indicators

monitor panel and checking tank levels.

Introduction
for tank capacities for your model.
HOLDING TANK HEATER
–If Equipped
Your motorhome may be equipped with black
water and gray water holding tank heaters to
allow use of waste utilities in freezing
temperatures. The holding tank heater power
switch is located near the monitor panel. The
illuminated switch will glow when the power is
on.
DO NOT operate the holding tank heater
unless you are providing a supplemental 12-volt
power source to recharge the house batteries.
This means either the shoreline cord must be
plugged into a 120-volt source, the auxiliary
generator must be operating, or the chassis
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 AND TANK DRAIN
VALVES
The waterline and tank 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.
See the “Water System Drain Valve
Locations” chart at the end of this section for
locations on your model.
WARNING
Service inlet access must be closed when
utility connections are not in use.
