passing a mechanical cleanout tool through the piping to open the drain. Passing a cleanout
tool through the waterless valve may cause damage to the internal seal that may potentially
allow sewer gases to escape into the RV interior. The waterless trap can be unscrewed from
the water lines. A label has been placed near the location of the waste valve that reads as
follows:
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.
Vent pipes and vents release air from the grey and black water holding tanks. On most
models 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 drain-
age system referred to as a “wet vent” where water
ows downward as air ows upward in the same pipe.
Some models are equipped with a side vent system. On
these models this label will be next to the termination
valve. This label should not be removed from your rec-
reation vehicle.
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 sucient water to assist in complete draining of the black water holding
tank. Repeat as needed.
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 eect, they may damage the plastic and rubber parts of the
plumbing system or the components
