PLUMBING
6. Add an odor control chemical to the sewage
holding tank through the toilet. These
chemicals are available at most RV stores.
7. Rinse sewage drain hose thoroughly with
water and stow.
NOTE: We recommend that you dump all
holding tanks before traveling to avoid
carrying unnecessary weight.
Using On-Site Sewer Hook-Ups
The sewer hose may remain attached to the
sewage drain outlet while the motorhome is
parked and connected to an on-site sewage hook-
up.
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
sewer 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
See
“Systems Monitor Panel”
in
Section 4 -
Appliances
for further information on the
monitor panel and checking tank levels.
See “Specifications” in
Section 1 -
Introduction
for tank capacities for your model.
HOLDING TANK HEATER
–If Equipped
Your coach may be equipped with black water
and gray water holding tank heaters to allow use
of waste utilities in freezing temperatures.
Holding Tank Heater Switch Location:
•
Models 25T and 25Q
- Located on back of
bath wall near thermostat.
•
Model 25R
- Located above thermostat near
rear TV.
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/coach
batteries. This means either the shoreline cord
must be plugged into a 120-volt source, the
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/coach battery.
NOTE: The holding tank heater pads are
electrical resistance-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/coach 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 Water Tank Drain valves
are used to drain water from the water tank and
the water supply lines when preparing the motor
home for storage or when sanitizing the water
system.
Refer to the “Water System Drain Valve
Locations” chart at the end of this section for
locations on your model.
