My upper tank and jet pump and pressure tank uses a pressure switch preset at 30-50,, I put a new pressure gauge on to see exactly where it cut off and cut on. (it never had one) it cut off at exactly 48 psi and cut on at exactly 26 psi. I've been reading how important it is to set tank at exactly 2 psi below cut on,,, but I got to thinking,, even though I am using an expensive digital air gauge,, the sort of cheaper round guage that reads the pressure is maybe off,,, so then how to get that exact 2 psi difference?

anyway, I set the tank at 25 psi, thinking maybe it was a bit off.

Compare the readings from both when the water pressure is above the 26 PSI cut-on. You could also get a second opinion on the water pressure by connecting another pressure gauge with garden hose thread to the drain valve.

Hey, wait a minute.

This is awkward, but...
