You can locate dump stations throughout the United States and Canada in Woodall’s, Rand
McNally Camp Guide, Good Sam Camp Guide, KOA Kampgrounds Camp Guide and vari-

dealer for assistance in the purchase and installation of a sewer hose or sewer hose extension

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 ow into the holding
tank.
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.
The toilet should be cleaned regularly for maximum sanitation and operational eciency.
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.
Black Tank Flush
The black tank ush (no fuss ush) inlet is typically located on the utility center panel (if so
equipped) labeled as “Tank Flush”. For models not equipped with a utility center, the inlet
is located on the side of the recreation vehicle. The location may vary depending on your
model. Attach a garden hose (connected to a pressurized fresh water source) to the black
tank ush inlet. The water goes directly into the black water holding tank sprayer connec-
tion, allowing you to remove debris and preventing accumulation. A check valve is incor-
porated in the plumbing lines to prevent back ow. 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 & Black Tank Drain) and leave the
black tank drain valve open.
2. Connect a garden hose from the water supply source to the black tank ush.
3. With the water source turned ON, ush the black water holding tank until the water
running out of the black tank drain valve is clear (not discolored or cloudy).
4. Disconnect the garden hose and close the black tank drain valve. Fasten the sewer hose
housing dust cap back on the tank ush inlet.
