Just installed new pump over the well, there is low water pressure to the house and the pump won't turn off.

New pump OVER the well? I take it that this is not a submerged pump.

True not submerged, need to know what is causing pump to keep running and water pressure to be low.

NOt real familiar with those type pumps, but I do know they have to be primed. Have you primed it?
