We have lived in our house for three years now. Last summer we began having lower water pressure when our sprinklers ran. This year as soon as the pressure tank is empty, I have no pressure at all. After a lot of research and troubleshooting, I decided to change our pressure switch. I increased from 30-50 to 40-60. The issue is not the pump or water supply. If I run the hose out of my pump house (off the bottom of my filter) the pump will run continuously and push as much water as I want , as long as I want. The problem comes when the tank is empty. The pump will run about 3 seconds then shut off. The pressure drops to 40 and it kicks on after about 10 seconds. This continues for at least an hour until our 60 gallon tank is full. I believe there is something restricting the water from entering the pressure tank. Does this make sense? Could it be as simple as replacing the tank and my problems are solved? Could it be a problem with the piping between my well and pressure tank?
