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:

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), 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.

The sewer tank flusher inlet (also known as the no fuss flush)
will have an identifying label next to it. This inlet is provided to
assist in flushing out the black water tank. The drain valve for
the black water tank must be OPEN to use this feature.
When the hose is connected, and when the water source is
turned on, it sprays water into the black water tank. This allows
you to rinse the black water holding tank by removing debris
and preventing accumulation. There is a check valve
incorporated in the plumbing lines to prevent back flow.
Using the Tank Flush Inlet:
1. Connect the flexible sewer hose to the 4 inch dump outlet.
2. Open the black water dump valve and leave it open. Allow
the tank to drain.
3. Attach a water hose to the tank flush inlet. Do not use your fresh water hose for this.
