Yard irrigation 3/4 horspower jet pump system problem.
The system consists of the electric motor and pump, 15 gallon tank, pressure gauge, and on/off pressure switch. The tank is set at 38 psi and the pressure switch at 40/50 psi. The pressure gauge shows at least 50 psi. I just had the pump repaired and I reinstalled it to the system. There are no leaks from the pump or pvc piping and connections. The pump cycles w/o any problems when it has a full water pumping load, but if I use the water very sparingly (e.g. filling a small pail), the pump cycles on and will not shut off when I turn off the water. If I then open the water faucet full to get full pressure, and then turn the water off, it will shut itself off. Could I have a pressure tank problem or whatever. All thoughts greatly appreciated. Thanks
