Drain And Waste System - Airstream Excella 1975 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 cor¬
rosion problems, with trouble free dump
valves. The main holding tank enables you to
use the toilet for several days away from
disposal facilities. On models equipped with
the auxiliary holding tank the waste water
from the sink, shower, bath and lavatory
drain into the 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 indi¬
cates full.
On International rear bath models the dump
valves are located in the rear trunk compart¬
ment. The main holding tank dump valve is
located on the roadside and the auxiliary
holding tank dump valve is located on the
curbside (see photo). On International center
bath models the dump valves are located on
the roadside, just behind the rear wheels, on
