We had a leaky connection pipe. I shut off the pump and valve until my husband came home to replace the connection. Meanwhile my children used all the water in the pipes. He fixed the connection and turned on the water pump. It sounded like it was running. We waited an hour for the pressure to go up. It never did. Still no water. We are afraid we will burn out the pump. How long does it have to run for water. Our water is not that far down. Do we have to prime it? If so how.
