Section 8: Plumbing System

Black/Grey Water System and Tanks
Water from the sinks and shower flows into the gray water (or waste water) holding tank.
Water from the toilet will flow into the sewage (or black water) 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
escaping 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
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
piping 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
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:
Sewer Hose Storage:
Depending on your RV model, the sewer drain hose may be stored in an exterior compartment
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 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” (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
REMOVE WATERLESS TRAP BEFORE
USING MECHANICAL DRAIN – CLEANING DEVICES
ABS plastic. Avoid using “Citrus” or biodegradable cleaners which contain “D-Limonene.”
They will damage plastic materials. Contact your dealer for repair or replacement.
