Sewage (black) tank preparation
It is important to add enough water to prevent solid waste buildup. Follow the
directions listed below and in the manufacturer's operator manual.
1.
Release one to two quarts (1 or 2 liters) of water into the toilet bowl.
2.
Follow the directions on your RV-approved toilet chemical bottle (customer supplied)
and put 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 particles
in the system.
Cleaning and Maintenance
The toilet should be cleaned regularly for maximum sanitation and operational efficiency.
Use only RV approved chemicals. 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.
Black Tank Flush (if so equipped)
The black tank flush inlet is typically located on the utility center
panel. The location may vary depending on your model. The inlet
color may be either white or black. Attach a garden hose connected
to a pressurized fresh water source to the black tank flush inlet. The
water goes directly into the black water holding tank sprayer con-
nection, allowing you to remove debris and preventing accumula-
tion. There is a check valve in the plumbing lines to prevent back
flow.Flush the black water tank each time the grey and black water
holding tanks are dumped or as needed.
1.
Dump the black water tank (see Gray Tank Drain and Black
Tank Drain) and leave the black tank drain valve open.
