• Do not use strong or full strength detergents to deodorize and disinfect.
Use odor control chemicals made especially for holding tanks.
• Do not put automotive antifreeze, ammonia, alcohol or acetone in
holding tanks. Some chemicals will dissolve plastic.
• Do not put large table scraps in the tanks. They could stick in or damage
the valve seals.
• Do not flush facial tissues, sanitary napkins or other non-dissolving
items into the system. Chemically treated for strength, the tissue will
not dissolve like toilet paper. Special holding tank tissue is available
at most RV supply stores. White toilet paper dissolves faster than
colored paper.
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
ABS plastic holding tanks and seals.
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.
The waste drain system provides adequate and safe storage and/or discharge of
waste materials. The drain system uses ABS plastic piping and fittings con-
nected to sinks, shower, toilet and holding tanks draining to an outside ter-
mination. The motorhome should be reasonably level for optimum operation of the
systems. The wastewater holding system consists of a wastewater holding tank
(grey tank). The grey water tank stores the sink, shower and clothes washer
drain water. A sewage holding tank (black tank) stores waste from the
toilet only.
Drain valves and a tank flush 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 dis-
charge outlet. The tank drain valves are located in the service center on the
roadside of the motorhome. Use the water monitor panel to observe tank lev-
els. When ready to drain the tanks, drain the sewage tank first. Next, flush the
black tank with the flush system. Drain the grey water tank. Using this
sequence helps flush solids from the sewer hose. When traveling, it is recom-
mend both holding tanks be empty or less than half full.
