Water pump will not shut off
My water pump will not shut off. The other day my water run out so I had to prime the pump. I got water back but now it won't shut off on it's own. I can manually shut it off from the pressure switch. I noticed the pressure gauge will reach a certain point to turn on but then seems stuck there. It won't raise or lower. I got good water pressure. I already know my well needs to be dug deeper because the water table in the area has dropped. Any suggestions would be greatly appreciated. Thank you
