Drain And Waste System - Airstream Caravanner 1977 Owner's Manual

Drain and Waste System
Your Airstream has a drain and waste
system. The system includes waste
holding tanks made from molded plastic,
free from corrosion problems, with
trouble free dump valves. The
main
holding tank
enables you to use the
toilet for several days away from disposal
facilities. The waste water from the sink,
shower, bath and lavatory drains into the
auxiliary holding tank.
Each tank has its
own dump valve, however, both tanks
drain through a common outlet. Therefore
you need to make only one connection
when hooking up in a trailer park with
sewer facilities.
When the toilet will no longer drain, the
main holding tank is full and must be
emptied.
Watch this closely, because
when the tank is full, sewage cannot be
emptied from the toilet bowl.
In models
with a central control panel, check the main
holding tank gauge. The auxiliary holding
tank must be emptied when the gauge on
the central control panel indicates full.
On 27, 29 and 31 ft, rear bath models the
dump valves
are located in the rear trunk
compartment. The main holding tank dump
valve is located on the roadside and the
auxiliary holding tank dump valve is lo¬
cated on the curbside. (See Fig. 1.) On 27,
29 and 31 ft. center bath models the dump
valves are located on the roadside, just
behind the rear wheels, on the main frame
rail. The main holding tank dump valve is
located forward of the sewage outlet. (See
Fig. 2.) On 21, 23 and 25 ft models the
main holding tank dump valve is located in
