DRAIN AND WASTE SYSTEM
The drain and waste system of your motorhome includes separate grey and
black tanks, remotely operated electric dump valves for each holding tank,
a macerator pump, and a high pressure hose with a drip proof valve on an
electric reel.
This self contained system enables you to use the toilet, sink, and wet bath
until a suitable disposal facility is available.

The portable waste pump is the ideal solution for emptying holding tanks
on recreational vehicles and avoiding dump stations. The macerator section
grinds waste down to a particle size of 1/8" maximum. The waste pump will
macerate and pump all waste and tissue normally found in recreational vehicle
waste systems.

: The waste hose is pressurized when operating mac-

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 versa-
tile 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 recom-
mends 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.
Pressing a dump valve switch and holding it for 2-3 seconds until it is lit opens a
holding tank valve. Each valve switch has a light that comes on to let you know
the valve is opened. Pressing it again for 2-3 seconds closes it. The macerator
pump has an ON/OFF toggle switch. The reel has a switch for retracting the
hose only, it is deployed manually.
