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.

When do you lose prime on a carbureted engine?

Loss of well prime means that the water inside an above-ground well pump has been lost along with water in the piping between the pump and the well .
