    With your pump off and all pressure released through a faucett, the bladder of the tank should be pressurized at 2 or 3 psi below the pressure setting where the pump normally starts. So if your pump is set to start at 40psi, for example, the bladder end of the tank should first be pressurized at 38psi.
