If you are dry camping and cannot immediately empty your holding tanks, reduce your ve-
hicle 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.
Never travel with full black or grey water holding tanks. 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
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 in-
dicating 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 release the black tank first,
followed by the grey tank. This will help rinse and debris
from the outlet and sewer hose. To make drainage easier, level
the RV.
1. Remove the sewer hose housing dust cap and attach 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 may be located
under the RV or on the utility center). Close the dump valve when the grey holding
tank is empty.
5. Remove, clean and store the sewer hose.
6. Close the sewer hose housing dust cap.
