Black and Grey Tank Drains

There are labels on the exterior of the recreation vehicle
indicating the location of the grey and black tank drains
(also called dump valves). Depending on your model,
you may have one or two valves. With one valve, the
gray and black tank will release contents simultaneously.
With the 2-valve set up, it is recommended that you re-
lease the black tank first, followed by the grey tank. This
will help rinse and debris from the outlet and sewer hose.
1. To make drainage easier, level the RV.
2. Remove the sewer hose housing dust cap and attach
the sewer hose (customer supplied).
3. Place the end of the sewer hose into the approved dump station.
4. 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.
5. Open the grey 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 grey holding
tank is empty.
6. Remove, clean and store the sewer hose.
7. Close the sewer hose housing dust cap.
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-
ous 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)
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.
It is important to add enough water to prevent solid waste buildup. Follow the
directions listed below and in the manufacturer's operator manual.

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.
