Section 8: Plumbing System
Sewer Hose Storage
Depending on your RV model, the sewer drain hose may be stored in an exterior compart-
ment marked “Sewer Hose” or it may be located in the hollow square tube bumper. The
bumper has removable plastic end caps, and the hose slides inside the hollow bumper.
Vents
Vent pipes and vents release air from the grey and black water holding tanks. On most mod-
els the exterior vent cap is attached to the roof and must be kept clear of obstructions to
perform as intended.
On some models, the vent pipe may be part of the drainage system referred to as a “wet vent”
where water flows downward as air flows upward in
the same pipe.
Some models are equipped with a side vent system.
On these models this label will be next to the termina-
tion valve. This label should not be removed from your
recreation vehicle.
Black/Grey Water Holding Tanks
Dump the gray and black water holding tanks before traveling to avoid carrying unnecessary
weight. The weight of the holding tank contents is not calculated into the RV cargo carrying
capacity. Traveling with full holding tank(s) could cause you to exceed the individual tire
ratings and/or the RV GAWR or RV GVWR. Potential damage to suspension components,
such as springs, tires and axles, could result.
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.
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.

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
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.
