Here is what happened on mine.....
On my coach, I adjusted the 12V air pump to cut off at like 65lbs. Then I adjusted the regulator to 55-60. Potty worked great...but pocket door freaked out. Lowered air pressure to 40. Pocket door happy, potty not so much.
Ended up with two regulators...One set to 45 for pocket door, and one set to 60 for potty.
I think what is happening is that the regulator is set for 60ish and when you are supplying more than that, it is fine. But with engine off and 120V pump off, the air pressure is dropping to 45ish and the potty is not happy with low air pressure. Adjusting the 12V cutoff to a higher pressure will probably fix.
