By adding water and using a RV approved deodorizing agent you will dissolve the contents
faster and will keep the drain lines and tanks clean and free flowing. These chemicals are
available at an RV supply store or your dealer.
Drain Pipes with Dry Sealing Valve (if so equipped):
Your RV may be equipped with a dry sealing valve that
prevents the escape of odors from your waste system and
eliminates the need for P-traps. Should the RV drain pip-
ing system become clogged and a mechanical cleanout
tool is used to open the drain pipe, it is important that the
dry valve be removed before passing the cleanout tool
through the piping. Passing a mechanical cleanout tool
through the waterless valve may cause damage to the in-
ternal seal that may potentially allow sewer gases to escape into the RV interior. The water-
less trap can be unscrewed from the water lines. A label has been placed near the location of
the waste valve that reads as follows:
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:
Another important part of this system is the vent
pipes and vents that release air from the grey and
black water holding tanks. On most models the ex-
terior 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” (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 termination 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 (this extra weight would reduce your available cargo capacity). Traveling with full
holding tank(s) could possibly 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
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.
