Section 8: Plumbing System
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 es-
caping 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, it is
important that the dry valve be removed before
passing a mechanical cleanout tool through the pip-
ing to open the drain. Passing a cleanout tool through the waterless valve may cause damage
Bathroom Tub / Shower
Keep the water heater and holding tank capacities in mind when using the fresh water sys-
tem. The used water will drain into the grey water holding tank.
 Be sure the water heater is ON and had sufficient time to heat the water.

If dry camping, be sure your 12-volt water pump is ON.
Unlike your home, the recreational vehicle does not contain a water pressure balance valve.
If someone is using the shower, it is recommended that the fresh water system
NOT BE
USED until they are finished.
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.
Water temperatures over 125°F (49°C) can cause severe burns instantly there-
fore, be careful when using hot water.
Always test the water temperature
before showering or washing.
