Dump Valve Rebuild?

[Gregory OConnor]

Pete, many owners use the onboard tanks to contain the aux
aircompressor charge. With that arangement you can eliminate the aux
air tank. Some OEM BB tanks on the bus will not drain back to the
other tanks in an effort to keep Airbrakes charged longer if an
appliance like the sewer Air valve fails and leaks air.

To keep from pressurizing the brakes and bag tank you may be able to
follow the pressure line from the sewer dump valve to the onboard
isolated tank. The Tank should have a plug that can be removed and
hard pipe the tank to an accessable shrader valve or a female
quickcoupler( like you have on air tools).

It sound as if you hooked the Microphor toilet to the new aux
aircompressor. you can also attach the dump valves to the aux
compressor tank and hardpipe the auxcompressor tank to one of the air
outlet fittings from the DD compressor. no need to run the aux
compressor while on the road.

If you are running the aux compressor with the inverter this may
also be a big draw on batteries.
