To fix this, first make sure the air volume control valve is not dirty or leaking.

What PSI should my pressure tank be?

Your well tank’s pressure should be set at 2 psi below the pressure switch’s cut-on point. This differs depending on your tank’s pressure settings. Most well tanks come set at 30/50. The cut-on pressure for the well pump is 30 psi, so the pressure of the tank should have a pressure of 28 psi.
