Draining The Holding Tanks - Fleetwood 2013 Recreational Vehicle Owner's Manual

Ensure that the black tank sewer drain system is
always closed and only opened when draining
at a dump station. Never allow your black tank
system to dry out unless it has been thoroughly
cleaned, sanitized and rinsed first.
For additional information, please refer to
the toilet operating manual in your Owner's
Information Package.

Draining the Holding Tanks

The holding tanks terminate in a valve arrange-
ment that permits draining each tank separately.
The valves are called knife valves. A blade
closes the opening in the sewer drain pipes. The
blade is connected to a T-handle. Do not pull
the holding tank knife valve open when the
protective cap is installed on the pipe. Pull the
T-handle to release the contents of the tank(s).

During self-containment use, the sewer line is
securely capped to prevent leakage of waste
material onto the ground or pavement. Always
drain the tank into an acceptable sewer inlet or
dump station.

Whenever possible, drain the holding tanks before
traveling. Waste water and sewage in the holding
tanks reduce the carrying capacity of the motor

sewage systems, waste materials will build up in
the tank and cause serious plugging if the tank

Holding tanks are enclosed sewer systems and as

valves are continuously open. In these cases,
keep the valves closed until the tanks are
and then drain into the sewage system.
The holding tank drain valve outlet is to be used
with a removable termination fitting that locks
onto the outlet with a clockwise twist. Clamp the
sewer drain hose to this fitting. A protective cap
should remain in place when you are not drain-
ing the tanks.
To drain the holding tanks:
1. Attach the sewer hose to the holding tank
outlet. Insert the end of the hose into the
sewer or dump station inlet, pushing it
firmly far enough into the opening to be
secure. In some cases, adapters may be
necessary or required between the line
and the inlet. Arrange the sewer hose so it
slopes evenly.
