Have Pressure then none then pressure again.
The pump seems to run a long time before cutting off. I have pressure and water for about 3 min then loose all water and pressure. After a while ,sometimes longer than others, the pump finally kicks on and I have water again. This repeats over and over. We found another leak. Fixed it then We changed the pressure switch. No help. Changed the pressure tank. Still we are getting burst of air and it starts another leak. What can cause the system to drain down and shut off for periods. The well , switch and pressure tank are about 100 yards from the house with a hydrant between at the stables.
