Before using the recreation vehicle, or after dumping the grey and black water holding tanks,
always add the proper amount of deodorant to the black water tank to prevent odors and
help break down holding tank contents (unless winterizing). Follow the deodorant bottle or
package instructions. Driving to a disposal site will normally loosen any accumulated waste
debris or solids from the sides of the holding tanks.
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). Always drain the black water holding tank
first so the following grey tank waste water can help rinse any solids or debris from the dump
outlet and sewer hose.
To make drainage easier, level the RV.
1. Remove the sewer hose housing dust cap, and at-
tach the sewer hose (customer supplied).
2. Place the end of the sewer hose into the approved
dump station.
3. 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.
5. Remove, clean and store the sewer hose.
6. Close the sewer hose housing dust cap.
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.
Never travel with full black or grey water holding tanks. This not only wastes
your fuel but depending on the location of the tank(s), it can affect your tow
vehicle handling characteristics.


Never leave the black tank drain in the open position continuously when
connected to the campground sewer system. Leaving the drain open will
allow the liquid to drain out increasing the potential for a blockage in the
tank. Keeping the drain in the closed position will prevent debris from
accumulating in the tank.

Do not add automotive antifreeze or caustic chemicals, such as laundry
detergents, into the holding tanks. Although these products may have a
deodorizing effect, they may damage the plastic and rubber parts of the
plumbing system or the components
