Toilet
The toilet is efficient and easy to operate. Prior to using the sanitation system, it is strongly
recommended to flush the toilet several times to release sufficient water into the holding
tank. Generally, more water is required only when flushing solids.
The toilet system will perform better when water is run for ten to fifteen seconds after flush
-
ing to ensure that the waste will proceed to the bottom of the tank.
If there is not a sufficient amount of water used during flushing, the waste materials may not
evacuate properly from the drain line to the tank. Clogged tanks and pipes could eventually
occur. For added convenience and better sanitation system performance, it is advisable to
always have four to six inches (10 - 15 cm) of water in the toilet. It is important to add
enough water to prevent solid waste buildup. The following guidelines will help to prevent
solid waste buildup.
Sewage (black) tank preparation
1. Release one to two quarts (1 or 2 liters) of water into the toilet bowl.
2. Follow the directions on your (approved RV) toilet chemical bottle (customer sup-
plied), by placing the recommended quantity of holding tank chemical into the toilet
bowl.
3.
Flush the toilet and allow at least two gallons (8 liters) of water to flow into the holding
tank.
Cleaning and Maintenance
The toilet should be cleaned regularly for maximum sanitation and operational efficiency.
For detailed information refer to the manufacturer’s operator manual.

It is important to prevent solid waste buildup. Follow the toilet manu-
facturer’s recommended instructions each time after emptying the black
water holding tank.

To prevent help toilet blockage, always use RV grade single-ply toilet pa-
per. Do not flush paper towels, diapers, sanitary napkins or other foreign
objects down the toilet.

Do not use chlorine (undiluted) or caustic chemicals, such as laundry
bleach or drain opening types, in the toilet system. These products dam-
age the seals in toilets and dump valves.
