Black and Gray Water Tanks
Draining
To empty one or both tanks, attach the sewer hose
by pressing the bayonet fitting onto the dump valve
outlet and rotating clockwise until it feels solid and
secure. Attach the outlet end of the hose to the sewage
outlet, making sure the hose is placed so it will drain
completely. Pull the main dump valve handle as far as
it will go and wait until the tank is drained. Close the
dump valve and partially refill the tank with clean water,
and repeat the process until clean. The main holding
tank must be flushed out until all paper and waste
material is removed. Should solids accumulate, close
the dump valve, fill the tank about half full with water,
and then tow the trailer for a few miles. The turbulence
and surging of the water will usually dissolve the solids
into suspension so the tank can be drained. Now pull
the auxiliary tank valve handle to drain the gray water
tank. When dumping, the main holding tank should be
dumped first, then the auxiliary holding tank. This will
help to rinse the sewer line with auxiliary holding tank
water. Replace the bayonet ring cap prior to traveling.

Black Water Tank Dumping
When you are in a park and connected to a sewer
outlet, keep the main holding tank dump valve closed
and empty the tank every few days, or whenever it
becomes almost full. Only by sending a large volume
of liquid, all at once, through the main holding tank will
toilet paper and other solids completely wash away.
This practice will avoid the accumulation of solids in the
main holding tank, which could lead to an unpleasant
cleaning job. Should solids accumulate, close the
dump valve, fill the tank about half full with water, then
tow the trailer for a few miles. The turbulence and
surging of the water will usually dissolve the solids into
suspension so the tank can be drained.
Draining the tanks as described will protect them from
freezing during storage. When traveling in sub-freezing
temperatures, use a winterizing solution designed for
RV use. Follow the directions on the container.
Black Water Tank Flush
The trailer has a water hose connector specifically
for flushing the Black Water Tank. To use, hook up a
hose and turn on full force. Within the tank, a spray
head with a multiple holed head will spray the interior
surface of the tank. The vacuum breaker and check
valve will be located inside the trailer above the exterior
connection. In most models, this will place them under
the lavatory.
The gate valve should be closed for the first couple of
minutes, and then opened to let the water out in a rush.
Repeat as needed.
