Do not dispose of table
scraps or cooking grease
into the tanks. They can
clog pipes or damage
termination valve seals.
CAUTION:
Do not dispose of
sanitary supplies or other
non-dissolving items into
the system. Facial tissue,
wet strength tissue, paper
towels or an excessive
amount of toilet tissue
can create clogging in the
holding tank system.
CAUTION:
Do not use any products
that contain petroleum
distillates or ammonia
in place of RV odor
controlling chemicals.
Petroleum distillates and/or
ammonia will damage the
plastic holding tanks, waste
drain piping and valve
seals.
What to Put in Holding Tanks
Grey Water Tank:
The grey water waste tank stores
the sink, shower and clothes
washer (if equipped) drain water. A
reduced mixture of chemicals may
help to control odor in the grey
tank.
Ensure that there is enough
liquid in the holding tanks prior to
dumping the waste holding tanks
to provide a smooth ow through
the valve, termination drain and
sewer hose. Empty the waste
holding tanks weekly to prevent
stagnation and overlling.
Black Water Tank:
To help prevent buildup,
pre-treat the sewage holding tank
with a few gallons of water and an
odor-control chemical (available
at most RV supply stores). First,
add approximately three or more
gallons of water to the holding
tank. Next, add the chemicals, in
accordance with the manufacturer
instructions. Pour mixture through
toilet into the holding tank. Be
careful not to spill the chemical
on hands, clothing, toilet bowl or
carpet. Hot weather conditions
may require adjusting the amount
of chemical used to control odor.
Repeat the chemical pre-charge
each time the black tank is cycled.
WARNING:
Most chemical mixtures for
holding tank odor control
are poisonous. Follow the
product manufacturer’s
directions and warnings
when using holding tank
additive. Do not use
products that contain
petroleum distillates or
ammonia in place of RV
odor controlling chemicals.
Waste Drain Hose
A exible three-inch sewer hose
attaches between the common
termination drain and the shore
sewer facility. Sewer hoses usually
come in 10 and 20 foot lengths.

hose may be a three or four-inch,
male or female thread pipe; or a
four-inch pipe with no threads.
Different style adapters are
available to t most congurations.
Hose ladders may also be
purchased to support the hose.
It is important the sewer hose
remains secure and restrained.
Always tighten clamps and
restraining devices before use.
Position the sewer hose inline
between the termination drain and
the shore tting. Restrain the hose
to prevent movement during use.
Wear protective and/or disposable
gloves when handling the sewer
hose.
To Attach the Sewer Hose:
Remove sewer hose from
storage.
Remove termination
cap. Align coupler tangs
with termination tabs.
Twist coupler clockwise
90º locking coupler to
termination drain.
Unscrew access port
and feed the sewer hose
