Drain the black water holding tank first. Grasp the
handle olthe black water knife valve (the large
one) firmly and slide the valve open with a
quick, steady pull.
Allow enough time for the tank to drain completely.
Rinse and flush the tank through the toilet.
When the tank is empty, push the handle in to
close the valve. Run enough water into the
tank to cover the bottom. This will aid the break
up of solid wastes.

Holding Tank Care
Since holding tanks don't rely on any sophisticated
mechanical devices for their operation, they are virtu-
ally trouble free. The most common problem is also an
unpleasant one - clogging. You can minimize the
chances of clogging by keeping the following consid-
erations ·in mind:
Keep the black water tank knife valve closed. Fill
tank to at least 3/4 full before draining. Be sure
to cover the tank bottom with water after
draining.
Use only toilet tissue formulated for use in septic
tank or RVsanitation systems ..
Keep both knife valves closed and locked, and the
drain cap tightly in place when using the
system on the road.
Use only cleaners that are approved for use in
septic tank or RV sanitation systems.
Use a special holding tank deodorant chemical
approved for septic tank systems in the black
water holding tank. These chemicals aid the
breakdown of solid wastes and make the
system much more pleasant to use.
Do not put facial tissue, paper, ethylene glycol-
based or other automotive antifreeze, sani-
tary napkins or household toilet cleaners in
the holding tanks.
Do not put anything solid in either tank that could
scratch or puncture the tank.
If the drain system does get clogged:
Use a hand-operated probe to loosen stubborn
accumulations.Seriollslyclogged P-traps may
require disassembly. Be careful not to over-
tighten when reassembling.
Do not use harsh household drain cleaners.
Do not use motorized drain augers.
Sometimes the holding tank valve will get clogged.
In this case, a hand-operated auger may be
necessary. Be ready to close the valve quickly
once the clog Is cleared. If the seal gets
damaged, it is easily replaced.
