4. To drain the gray water tank, repeat the steps
above using the small knife valve. This tank
is drained last to aid in flushing the outlets
and hose. The gray 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
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 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
station. 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.
6. Replace sewer or dump station covers.
