Drain and Waste System
Your touring coach has a drain and waste system that
includes waste-holding tanks made from corrosion-
free, molded plastic, with trouble-free dump valves�
The main (Black Water) holding tank enables you to
use the toilet for several days away from disposal
facilities� The wastewater from the sink, shower, bath,
and lavatory drains into the auxiliary (Gray Water)
holding tank�
Each tank has its own dump valve with both tanks
draining through a common outlet� Therefore, only one
sewer hose connection is needed when hooking up to
a dump station�
Almost all campgrounds will have dumping facilities�
Park directories, such as Woodalls and Rand McNally,
also list dumping stations� Furthermore, the navigation
systems GPS can be used to locate nearby dumping
stations or highlight stations along your route�
Check your monitor panel frequently (main Multiplex
control panel or Seelevel monitor)� When the Black
Water holding tank is completely full, sewage cannot
be emptied from the toilet bowl� If the Gray Water
holding tank is overfilled, drain water will back up into
the shower floor pan and cause an unpleasant cleaning
job� Never drain the tanks at any place other than an
approved dumping station�
WARNING
Never put wet strength paper towels or tissues
in your holding tank since they will not dissolve
and can catch in the mechanism of the dump
valve. Colored toilet tissue is slower to dissolve
than white. Most motorhome accessory stores
offer tissue designed for RVs that will completely
dissolve.
Macerator Pump
The portable waste pump is the ideal solution for
emptying holding tanks on touring coach’s and avoiding
dump stations� The macerator section grinds waste
down to a particle size of 1/8-in� maximum� The waste
pump will macerate and pump all waste and tissue
normally found in recreational vehicle waste systems�
CAUTION
The waste hose is pressurized when operating the
macerator pump. Secure the loose hose end at the
disposal facility with supplied inlet adaptors before
turning on pump.
The high-pressure waste hose is stored on an electric
hose reel and connected to the Discharge Port
Adaptor� It has a threaded, drip-proof valve with a
versatile, two-size, threaded adaptor allowing the valve
to be connected to 3 sizes of threaded inlets, including
an exterior home sewer clean-out� The adaptor snaps
over the valve threads� A rubber ring is also provided
to lodge into a non-threaded inlet� If the rubber ring
seems loose when used, Airstream recommends using
some type of weight to further secure the hose�
Each holding tank, the macerator pump, and macerator
pump electric hose reel have individual switches which
are located in the roadside utility compartment� Each
valve switch has a light that illuminates to let you know
the valve is opened� Pressing a dump valve switch and
holding it for 2-3 seconds until it is lit opens a holding
tank valve� Pressing it again for 2-3 seconds closes it�
The macerator pump has an ON/OFF toggle switch�
The reel has a switch for releasing and retracting
the hose, once the hose is released it is deployed
manually� To retract the hose, press and hold the
retract button while guiding the hose in place�
NOTE
Do not run Macerator pump more than 15 minutes
continuously. Do not run the Macerator pump dry
for more than 30 seconds. THE MACERATOR WILL
NOT HANDLE HARD SOLID OBJECTS, SANITARY
NAPKINS OR RAGS. Never put wet strength paper
towels, tissues, or sanitary napkins in your holding
tank. They will not dissolve and will jam the
mechanism of the dump valve and the macerator
pump impeller.
