Since holding tanks don't rely on any sophisticated mechani-
cal devices for their operation, they are virtually trouble tree.
The most common problem is also an unpleasant one-clog-
ging. 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
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 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.
