What to Put in Holding Tanks - Black Water Tank
Before initially operating the toilet, treat the sewage holding tank with a pre-charge 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, mix the chemicals, in accordance with the manufacturer instruc-
tions, with approximately one gallon of water. Pour mixture through toilet to the holding tank. Be
careful not to spill the chemical on your 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
to the holding tank each time the tank is cycled.
WARNING:
Most chemical mixtures for holding tank odor control are poisonous. Follow the prod-
uct manufacturer's directions and warnings when using holding tank additive. Do not
use any products that contain petroleum distillate or ammonia in place of RV odor con-
trolling chemical. Petroleum distillate or ammonia will damage the ABS plastic holding
tanks and seals.
What to Put in Holding Tanks - Grey Water Tank
The grey water waste tank stores the sink, shower and clothes washer drain water. A reduced mix-
ture 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, drain pipe and drain hose. Empty the waste holding tanks
weekly to prevent stagnation and overfilling.
