I would first see if the tank has any air left in it.
If water comes out of snifter valve….it is bad.
Could need to replace the pressure switch if the contacts are wore out.
Drain system completely. If the pressure is 2 lbs. less than the cut in pressure.in the tank that is…..your fine. If not…..Make adjustments to correct this so it will operate correctly.
Only check pressure in tank ONLY when the water is out of tank.
