Plumbing Systems
flush, the average recreation vehicle system uses one to
three quarts (1-3 liters). 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.
To prevent help toilet blockage, always use RV grade sin-
gle-ply toilet paper. Do not flush paper towels, diapers, sani-
tary napkins or other foreign objects down the RV toilet.
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 toilet chemical bottle (cus-
tomer supplied), 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.
Waste (grey) holding tank preparation
No special preparation is required, however, placing a small
quantity of chemicals into this tank, such as baking soda or
an approved RV chemical, will reduce odors from food parti-
cles in the system.
Cleaning and maintenance
The toilet should be cleaned regularly for maximum sanitation
and operational efficiency. Do not use chlorine (undiluted) or
caustic chemicals, such as laundry bleach or drain opening
types, in the toilet system. These products damage the seals
in toilets and dump valves. For a “sticky” toilet ball valve, apply
petroleum jelly; this provides waterproof lubrication and will
not damage the seals.
