The shower faucet may include a vacuum breaker for the shower. There are two purposes
for this breaker:
To prevent siphoning water through the hose from another fixture.
To prevent water from being retained in the hose.
The showerhead DOES NOT have a complete shut-off valve (the complete shut-off is at the
faucet). The showerhead may drip slightly in the OFF position after use; this is normal and
does not indicate a leak or defect.
Maintenance
Refer the manufacturer's user guide or label instructions for detailed cleaning information.
The tub/shower walls are made of ABS plastic material. Use a mild detergent soap and warm
water to clean. Do not use gritty or abrasive particle soaps or scouring compound to clean
ABS plastic. Avoid using "Citrus" or biodegradable cleaners which contain "D-Limonene."
They will damage plastic materials.
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 escaping into
the RV. During travel, water from the P-traps may
spill and permit odors into the RV. By adding wa-
ter 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, it is important 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 wa-
terless 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 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.
