• Access cap for sewer pipe. Located directly under
sewer drain, remove cap and feed exible sewer hose
up through, and attach to the drain outlet.
• Exterior faucet. For mixing the water temperature for the
exterior shower head.
NOTE: It is typical to have one gray and one black
termination valve for the gray and black tanks re-
spectively. However, depending on the quantity and
location of bathrooms, some floor plans have two
termination valves on a single black tank, and other
models have two black tanks with their own individual
termination valves.
Emptying Waste Water Holding Tanks
1. Remove the cap from the sewer drain and connect
your exible sewer drain hose.
2. Place the other end of the exible sewer drain hose into
the dump station inlet. Be sure both ends of the exible
sewer drain hose are secured.
3. Drain the black water holding tank rst by pulling the
termination valve handle away from the valve body.
Be sure to allow sucient 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 ush pedal, ush handle, or use
the black tank ush (if equipped).
4. Drain the gray water holding tank by pulling the
termination valve handle away from the valve body.
Draining the gray water holding tank aer the black
tank allows the soapy water in the gray water holding
tank to rinse the exible sewer drain hose.
5. When both the black water and gray water tanks are
emptied, close the termination valves by pushing the
handles back to the closed positions.
6. Remove the exible sewer drain hose, and rinse it
thoroughly with clean water. Remove the other end
from the dump station inlet, and replace it in its stor-
age container.
7. Replace the sewer caps on both the motorhome outlet
and the dump station inlet.
8. Flush the toilet a few times to add a small amount
of water to the black tank. is will help keep any
remaining solids from drying to the tank surfaces.
NOTE: Always wear rubber or vinyl gloves and pro-
tective eyewear when emptying the holding tanks.
Black Tank Flush
When connected to a campground sewer system, it is
best to 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.
NOTICENOTICE
Typical black tank flush
Do not use the black tank ush system unless the black
tank termination valve is in the open position.
The black tank could overll if the termination valve is
not open, which will result in an unsanitary condition,
leading to illness or potential personal injury.
CAUTIONCAUTION
If your motorhome
has a black tank
rinse system (San-
T-Flush, or similar
rinse port), connect
it to the dump sta-
tion water supply
with a garden hose
reserved for this
task. For sanitary
reasons, do not use a
fresh water hose for
the black tank rinse.
Do not turn on the
rinse water until the
black tank has been
emptied.
Aer black tank dumping, some solids may be le at
the bottom of the black water tank as well as on the tank
sidewalls. e black tank ush is designed to help rinse
and ush the black tank. Turn on the water and let it run
for several minutes to help remove solids le in the tank.
During the ushing process, be sure the termination valve
remains open and the exible sewer drain hose remains
connected between the motorhome's sewer drain outlet
and the dump station inlet.
