Draining The Holding Tanks - Fleetwood 2012 American Eagle Owner's Manual

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 and cable assembly
mounted in the utility compartment. 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.
Drain the holding tanks only when they are at least
⁄ -full. If necessary, fill the tanks with water to

full. This provides sufficient water to allow com-

plete flushing of waste material into the sewer line.
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 chapter.
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
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
Holding tanks are enclosed sewer systems and as
such must be drained into an approved dump station.
Both black and gray water holding tanks must be
drained and thoroughly rinsed regularly to prevent
accumulation of harmful or toxic materials.

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.
2. Drain the black water holding tank first.
Grasp the handle of the black water knife
valve (the large one) firmly and slide the
valve open with a quick, steady pull.
