Black Tank Flush System
(If Equipped)
The black water holding tank is equipped with
rinsing spray heads that will aid in the removal
of
sewage residue from the interior
of
the hold-
ing tank.
To
operate the tank flushing system,
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
connec-
tion.
2.
Turn on water supply
to
garden hose and
allow the water to
mn
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.
Rinse ont the sewer hose with
fi-esh
water
and remove the sewer hose fi'om the dump
station.
6.
Replace sewer or dump station covers.
7. After rinse water has thoroughly drained
from the black tank, close the knife valve
and replace the termination cap.
If
you are
parked at a site with a semipermanent
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 continually.
Run enough water into the tank to cover
the bottom. This will aid the break up
of
solid wastes.
It
is important to keep at least
20 gallons
of
water with deodorizer in the
black water tank at all times.
