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.
P-Traps (if 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 an 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.
Waterless Traps (if equipped)
Your RV may be equipped with a
waterless trap that prevents the escape
of odors from your waste system and
eliminates the need for water-filled
P-traps.
Should the RV drain piping system become clogged, it is important
that the waterless trap be removed before passing a mechanical clean
out tool through the piping to open the drain. Passing a clean out tool
through the waterless trap 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:

USING MECHANICAL DRAIN CLEANING

Sewer Hose Storage
Depending on your RV model there are different locations for sewer
drain hose (customer supplied) storage.
•
Exterior compartment marked "SEWER HOSE"
•
Hollow square tube bumper. The bumper has removable plastic
end caps, and the hose slides inside the hollow bumper.
•
PVC storage tube mounted under the frame.
PLUMBING SYSTEM
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 RV.
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. 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.
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 3/4 full.
This will provide sufficient water to assist in complete draining of the
black water holding tank. Repeat as needed.
Before using the RV, or after dumping the grey and
black water holding tanks, always add the proper
amount of black tank treatment to the black water tank
to prevent odors and help break down holding tank
contents (unless winterizing). Follow the treatment
bottle or package instructions. Driving to a disposal site will normally
loosen any accumulated waste debris or solids from the sides of the
holding tanks.
