Black and Gray Water Tank 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
8-16
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
garden hose and turn it on. Within the tank, a head with
multiple holes will spray the interior surface of the tank.
Once the tank is about half full, turn the garden hose
off and flush the water from the tank using the dump
valve. The valve should be closed for the first couple of
minutes, and then opened to let the water out in a rush.
Repeat as needed.
It is recommended the tank flush be used on a regular
basis or the holes on the spray head may become
clogged�
Drain Systems Cleaning
The only cleaning agents that can be used without
causing harm to the system are household ammonia
and tri-sodium phosphate in small quantities. Do not
use any product that contains any portion of petroleum
distillates. This type of product will attack the rubber
seals of your toilet and dump valve. Also, do not use
any dish detergent or abrasive cleaners. All products
should be marked as approved for ABS drainage
systems.
NOTICE
Do not use a pipe snake on clogged drains as it
could result in damage to internal components of
the drain system.
