Draininq The Holdinq Tanks - Fleetwood 1998 American Tradition Owner's Manual

The holding tanks terminate in a valve alTangement that
permits draining each tank separately.
The valves are called knife valves, and are mounted in the
utility compartment located at the left rear of the motor home.
A blade closes the opening in the sewer drain pipes. The blade
is connected to a T-handle that is pulled 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 pave-
ment. Do /lot pull the holding tank knife valve open when
the protective cap is installed
all
the pipe. 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 home. See the Motor Home
Loading section in the On The Road chapter in this manual.
Drain the holding tanks only when they are at least
3/4
full. If
necessary, fill the tanks with water to
3/ 4
full. This provides
sufficient water to allow complete flushing of waste material
into the sewer line.
During extended or semi-permanent hookups to sewage
systems, waste materials will build up in the tank and cause
serious plugging if the tank valves are continuously open. In
these cases, keep the valves closed until the tanks are
3/ 4
full,
and then drain into the sewage system.
The holding tank drain valve outlet is to be used with a re-
movable 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.
