Black/Grey Water System and Tanks

Water from the sinks and shower flows into the gray water (or wastewater) holding tank.
Water from the toilet will flow into the black water (or sewage) holding tank (see Black/
Grey Water Holding Tanks).
Drain Pipes with P-Trap (if so equipped)
The drain pipes may be equipped with a "P-trap" installed to help prevent odors from escap-
ing into the RV. During travel, water from the P-traps may spill and permit odors into the
RV. By adding water and using a RV approved deodorizing agent you will dissolve the con-
tents 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 piping system become clogged, it is im-
portant that the dry valve be removed before 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 un-
screwed from the water lines. A label has been placed near the location of the waste valve
that reads as follows:
REMOVE WATERLESS TRAP BEFORE
USING MECHANICAL DRAIN CLEANING DEVICES
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
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 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 termination
valve. This label should not be removed from your rec-
reation vehicle.
Black/Grey Water Holding Tanks
Dump the gray and black water holding tanks before trav-
eling 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.
