When you checked the bladder tank pressure did you shut the power off and drain the system down? If not you were getting a false reading. Set the pressure again. To set the air pressure in a bladder tank, look at the cut-in pressure on your pressure switch. Now drain the line down with the pump off. When there is no more water coming out of the hose bib that you drained the system down with set the pressure in the bladder tank at 2 lbs. Below the cut-in pressure. Check it with a tire gage. If your pressure control is set to come on at 30 PSI and go off at 50 PSI then your gage should read 28 PSI. Hope this helps and thank you for rating my reply.
