Cayman 2006 Water Systems — Section 6 • 155
NOTE:
Never 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 products that contain petroleum distillate or ammonia in place of RV odor
controlling chemicals. Petroleum distillate or ammonia will damage the plastic holding tanks
and seals.
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 instructions, 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 product
manufacturer’s directions and warnings when using a holding tank additive. 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.
Grey Water Tank:
The grey water waste tank stores the sink, shower and clothes washer 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 fl ow through the valve, drain pipe and drain hose. Empty the waste holding tanks weekly to prevent
stagnation and overfi lling.
Waste Drain & Sewage Tanks
The waste drain system provides adequate and safe storage and/or discharge of waste materials. The drain
system uses ABS plastic piping and fi ttings connected to sinks, shower, toilet and holding tanks draining to an
outside termination. The motorhome should be reasonably level for optimum operation of the waste systems. The
wastewater holding system consists of a grey water tank that stores the sink, shower and laundry washer drain
water, and a black holding tank that stores waste from the toilet.
Drain valves and a tank fl ush system dispose waste through a common termination. Each holding tank has a
separate drain valve dumping the waste water (grey water) and sewage (black water) through a common single
discharge outlet. The tank drain valves are located in the service center on the roadside. Use the Systems Control
Center to monitor tank levels. When ready to drain the tanks, drain the sewage tank fi rst. Next, fl ush the black
tank with the fl ush system. Close black tank valve after fl ushing tank. Drain the grey water tank. Using this
sequence helps to fl ush solids from the sewer hose. When traveling, it is recommend both holding tanks be empty
or less than half full.
