basement air pressure gauges in 2000 lxi

[Toranch]

It's taken me four years, but I've finally figured out what these two adjustable air pressure gauges do. The one with a visible reading on all the time is the slide seal pressure. The one with the higher Guage the reads zero most of the time is for the Microphone toilet. From what I've read in the forums, the slide seal should be set @ 7-10 psi, and the toilet should be set @ 50-60 psi.
