Drain/Waste/
Vent Systems
Your Airstream has a drain and waste system
similar to the one in your home. The new
twin tank system includes a 20 gallon waste
holding tank and a 10 gallon auxiliary waste
tank for sink and shower waste. Both tanks
are made of molded plastic, free from cor¬

problems
and
are
equipped with
trouble free dump valves which terminate in a
single outlet. This system enables you to use
all trailer facilities without an outside bucket
or external sewage connection for approxi¬

is full and must be emptied. Watch this

cannot be emptied from the toilet bowl. In
models with a central control panel, watch
the tank level indicator. To empty the tank,
attach the sewer hose by pressing the bayonet
fitting onto the dump valve outlet and rotate
clockwise until it feels solid and secure.
Attach the outlet end of the hose to the
sewage outlet, making sure that the hose is
placed so that it will drain completely. The
dump valve has two wire loops that lock the
handle in the closed position. To unlock push
outward on the wire loops and they will snap
loose, permitting you to open the valve. Pull
up the dump valve handle as far as it will go
and wait until the tank is drained. Close the
dump valve and refill the tank with 5 to 10
gallons of clean water and repeat the opera-
