Microphor toilet and variable speed pump

[Richard Hayden]

Along with air regulators for the Microphor we all should put them on the air
line to the dump valves. According to Randy it would extend the valves life by
not pushing so hard when running with the air pressure is over 100 lbs. Just
another project I haven't gotten around too yet.

Yes, I have the air-operated Microphor (with a small 12v compressor
in the basement compartment nearby). It would be worthwhile to check
the Microphor website for the installation/troubleshooting manual for
your model. I may get around to installing a pressure controller for
the water supply to the toilet. I actually have a nice one in my
'junk' box from a long-dead drip irrigation system I once had.
