Since holding tanks
don't
rely on any sophisticated mechani-
cal devices for their operation, they are virtually trouble free.
The most common problem is also an unpleasant one -
clogging.
You
can minimize the chances
of
clogging by
keeping the following considerations in mind:
» Keep the black water tank knife valve closed. Fill tank to at
least % 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
RV
sanitation 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, sanitary 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 accumula-
tions. Seriously clogged P-traps may require disassembly. Be
careful not to overtighten 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.
