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 flow through the valve, termination drain and
sewer hose . Empty the waste holding tanks weekly to
prevent stagnation and overfilling .
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 gallons of water to the holding
tank . Next, add the chemicals, in accordance with the
manufacturer instructions . Pour mixture through toilet
to 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 .
WASTE DRAIN HOSE
A flexible 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 .
The shore fitting for the sewer hose may be a three
or four-inch, male or female thread pipe; or a four-
inch pipe with no threads, covered by a metal plate .
Different style of adapters are available to fit most
configurations . Hose ladders may also be purchased to
support the hose .
It is important that the hose remains secure . Always
tighten clamps and restraining devices before use .
Lay the sewer hose in-line between the termination
drain and the shore fitting . Restrain the hose to
prevent movement during use . Wear protective and/or
disposable gloves when handling the sewer hose .
SEWER HOSE STORAGE
The motorhome comes equipped with a sewer hose
storage compartment in the rear bumper .
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
distillate or ammonia in place of RV odor controlling
chemicals . Petroleum distillate or ammonia will
damage the ABS plastic holding tanks and seals .
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 chemical . Petroleum
distillates or ammonia will damage ABS plastic
and termination seals .
