vehicle speed until you reach a dumping station.
When connected to the sewer drain line at a campground, keep the “black tank drain” valve
closed until the holding tank is at least ¾ full. This will provide sufficient water to assist in
complete draining of the black water holding tank. Repeat as needed.
Before using the motor home, 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.
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.

The grey tank drain and black tank drain are also referred to as 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.
1. To make drainage easier, level the motor home.
2. Remove the sewer hose housing dust cap, and attach the sewer hose.
3. Place the end of the sewer hose into the approved dump station.
4. Open the black tank dump valve (close it when the black water holding tank is emptied).
5. Open the grey tank dump valve (close it when the grey holding tank is emptied).
6. Remove, clean and store the sewer hose.
7. 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.
Please contact your RV dealer for assistance in the purchase and installation of a sewer hose
and/or sewer hose extension (if needed).
Macerator Pump System (if so equipped)
Your motor home may be equipped with a macerator pump system used to discharge waste
from the gray and black waste tank. The system has a 1-1/2 inch diameter flexible hose that
