Black Tank Flush (if so equipped)
The black tank flush (no fuss 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 connection, allowing you to remove debris and preventing
accumulation. 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.

Open the black tank dump valve (depending on your model the valve may be located
under the RV, or on the utility center). Close the dump valve when the black water
holding tank is empty.
4.
Open the grey tank dump valve (depending on your model the valve will be located
under the RV or on the utility center). Close the dump valve when the grey holding tank
is emptied.

You can locate many dump stations throughout the United States and Canada in Woodall’s,
Rand McNally Camp Guide, Good Sam Camp Guide, KOA Kampgrounds Camp Guide and
various other publications. Some fuel stations also have dump stations.
Please contact your RV dealer for assistance in the purchase and installation of a sewer hose
or sewer hose extension (if needed).
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 (RV approved) toilet chemical bottle (customer 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 particles
in the system.
Cleaning & 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.
It is important to add enough water to prevent solid waste buildup. Follow the
directions listed below and in the manufacturer’s operator manual.
