PLUMBING
SYSTEMS
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.
Drain the holding
tanks.
only when they are at least
3/4-full.
If
necessary, fill the tanks with water to 3/,-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/,-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.
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 between the
line and the
inlet.
2. Arrange the
sewer
hose so it slopes evenly.
3.
Drain the black water holding tank first. Grasp the T-handle of
the
black water knife valve firmly and pull the valve open with
a quick, steady
pull.
4.
Allow enough time for the tank to drain completely. Rinse and
flush the tank through the
toilet.
