Waste Water System
The waste water system of your motorhome consists of bath-
room fixtures, drainage plumbing, waste water holding tanks,
drainage vents, and sewage valves. It is important to familiar-
ize yourself with the motorhome’s waste water system, for it
does require monitoring, routine and long-term maintenance.
Waste Water Holding Tanks
Your motorhome is fitted with waste holding tanks designed
to collect waste water and waste solids. Typically, waste water
from kitchen sinks, bathroom sinks and bathroom shower(s)
is collected and stored in the gray water tank, while solids
from bathroom toilet(s) is collected and stored in the black
water tank. Depending upon the floor plan layout, all bath-
room waste water may drain to the black water tank. Some
Class B models have a cassette toilet, where the cassette serves
as the black water tank.
Waste water collection tanks have valves that allow for emp-
tying the tanks into an external sewage collection facility,
commonly known as a ‘dump station.’
NOTE: When traveling, it is good practice to minimize
the waste water (gray and black) carried in your mo-
torhome. This will allow for carrying capacity for other
items, if needed. Refer to Section 5, Occupant and
Cargo Carrying Capacity (OCCC).
Monitoring the level of fresh and waste water is pro-
vided on the Multiplex touch-screen panel, typically
indicated in 1/3 increments (except for models with
a cassette toilet).
Holding Tank Heaters (if equipped)
Your motorhome may be equipped with holding tank heaters,
which are designed to help prevent freeze damage to fresh and
waste water holding tanks.
These heaters are installed underneath the holding tanks and
are controlled through the main multiplex panel or a separate
switch. Holding tank heaters are manually operated, and
should be used whenever you encounter weather conditions
that are at or below 32° F (0° C).
Termination Valves and Sewage Discharge
The components of the sewage discharge system are located
underneath and to the rear of the motorhome. Configurations
vary due to model and floor plan, but all function the same.
Emptying Waste Water Holding Tanks
NOTE: Always wear rubber or vinyl gloves and pro-
tective eye-wear when emptying the waste water
holding tanks.
1. Remove the cap from the sewer drain and connect the
flexible sewer drain hose (typically customer supplied).
2. Place the other end of the flexible sewer drain hose into the
dump station inlet. Be sure both ends of the flexible sewer
drain hose are secured.
3. Drain the black water holding tank first by pulling the
termination black-colored valve handle away from the
valve body. Be sure to allow sufficient time for the black
water holding tank to completely drain, then rinse the
black water holding tank with several gallons of water by
depressing the toilet flush pedal, hand flush handle, or
use the black tank flush (if equipped).
4. Drain the gray water holding tank by pulling the gray-col-
ored termination valve handle away from the valve body.
Draining the gray water holding tank after the black tank
allows the soapy water in the gray water holding tank to
rinse the flexible sewer drain hose.
5. When both the black water and gray water tanks are
emptied, close the both termination valves by pushing
the handles back to the closed positions.
Typical termination valve layout
When connected to a campground sewer system,
keep the termination valves CLOSED until the waste
water storage tanks need to be emptied. Doing so will
prevent campground sewer gases from entering the
waste water system of your motorhome.
NOTICE NOTICE
The termination valve assembly limits ground clearance
of the vehicle. To prevent damage, use caution when
encountering rough pavement, curbs, speed bumps, etc.
