I'm curious - I thought the HH pump was internally regulated to about 60 psi.
I've been going through issues with my half bath toilet. AnnaMaria and John at Mullaney & Associates felt that 60 psi water pressure was too high relative to the air pressure after I rebuilt the sequencer valve and had problems. I ended up putting an adjustable water pressure regulator on that circuit to be certain that wasn't the issue (I dismissed how it could have worked previously as well as how the rear toilet works perfectly with no regulator).
After rebuilding the sequencer with the original center body section several times it would work only on the 12 volt lower pressure water pump. As soon as I turned on the HH, the flapper would open and then nothing else would happen...ever. Thought was the water pressure was overpowering the air pressure on the internal spindle.
When rebuilding (too many times to count), I would discover the spindle had blown thru the top section of the sequencing valve as if I assembled it incorrectly. It turns out the combination of too much water pressure and a lifed-out sequencer body was to blame.
Now, with a new sequencer body, a lot of patient (very/extreeemely patient) trouble shooting and instruction from AnnaMaria and John, my 1/2 bath toilet is working...with the pressure regulator set to 40 PSI for the water and my air tanks drained of water/moisture (very important).
Another important thing to know is the actual water pressure relative to the air pressure. I estimate air must be higher by 10-20 psi but would submit to Richard and Tom due to their vast experience.
I don't know if this will help, but it can't hurt.
Good luck!
