Plumbing Systems and Holding Tanks

the tank to cover the bottom. This will aid the
break up of solid wastes, and reduce “pyra-
miding” of waste material.
4. To drain the “grey” water tank, repeat the
steps above using the small knife valve.
This tank is drained last to aid in flush -
ing the outlets and hose. The “grey” water
knife valve may be left open in a semi-
permanent hookup.
5. See the tank flush system instructions in
the next section if your recreational vehicle
is so equipped.
6. Remove the sewer hose and cap the outlet.
7. Rinse out the sewer hose with fresh water
and remove the sewer hose from the dump
station.
8. Replace sewer or dump station covers.
Black Tank Flush System
(If Equipped)
A black water holding tank system that is
equipped with a flush system has rinsing spray
heads inside the tank that will aid in the removal
of sewage residue from the interior of the
holding tank. To operate the tank flushing sys -
tem, follow the procedures for Draining The
Holding Tanks in this chapter. After dumping
the gray water tank proceed as follows:
1. With the dump valves open, attach a garden
hose to the black tank flush inlet connection.
2. Turn on water supply to garden hose and
allow the water to run for approximately
three minutes to flush tank.
3. Turn off water supply to garden hose.
4. Remove hose from black tank flush inlet
connection and store hose.
5. After rinse water has thoroughly drained
from the black tank, close the knife valve
and replace the termination cap. Rinse
out the sewer hose with fresh water and
remove the sewer hose from the dump sta-
tion. If you are parked at a site with a semi-
permanent sewer hookup, keep the black
water knife valve closed to allow the waste
level to build up. The outlet will probably
clog if you leave the knife valve open con-
tinually. Run enough water into the tank to
cover the bottom. This will aid the break up
of solid wastes.
6. Replace sewer or dump station covers.
Please...Practice good housekeeping when
draining wastes at a campsite or disposal sta-
tion. Leave the site in good order. Above all, do
not pollute.
Holding Tank Care
Since holding tanks don’t rely on any sophis-
ticated mechanical devices for their operation,
they are virtually trouble-free. The most com-
mon 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.
Do not use the same hose you use for filling the pota-
ble 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.
