Turn on the water and watch the pressure gauge. Note the pressure the pump turn on and off at. It should be a 20# difference I.E 30/50 psi.
Check the air pressure in the tank wit hno water in the tank. It should be 1-2 psi less than the pressure setting to turn on the pump. I. E. 29-28 psi for 30 psi cut-in. If not adjust as needed.
If you don’t have a captive air precharged tank, drain your tank and then refill it. If you have an automatic air volume control on the tank search web on http://www.google.com for AVC + “pressure tank” exactly like that and read about them.
If your pump can’t produce the pressure to shut itself off, you have a leak somewhere or the pump needs to be checked out electrically.
