Question
i am is florida and we just had a hard freeze. The PVC pipe comming from the well to the pump motor cracke(above ground) so I put all new pvc in its place.The problem is now I cant get any water to pump.The pump will stay running so I have to unplug it. It has a pressure tank on top. Does it need to be Primed now, if so how or could it be somthing else.? thanks in advance

Answer
Sounds like the pump may have lost its prime, so I would start by trying to prime it and see if it will work.  At the bottom of the well line should be a foot valve or some other device that holds prime in the suction line.  If priming doesn't help, you might pull the line and inspect the foot valve to make sure it is working.
