Plumbing Systems and Holding Tanks
Please...Practice good housekeeping when
draining wastes at a campsite or disposal
station. Leave the site in good order. Above all,
do not pollute.
Holding Tank Care
Since holding tanks don’t rely on any
sophisticated mechanical 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
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, feminine hygiene
products or household toilet cleaners in the
holding tanks.
• Do not put anything solid in either tank
that could scratch or puncture the tank.

CAUTION
Do not use the same hose you use for filling the
potable water tank, or for connection to the city
water inlet. This is especially true if you the connect
the quick connect hose to the typical rinsing hoses
at most dumping stations. Use of a different hose
will insure that you will not contaminate your fresh
water supply.
