I have a shallow irrigation well that runs dry in late summer. I have a 3/4hp pump with a 30/50 switch and low pressure cut-off. And I have a pressure tank. When the well runs dry the pump will continue to run, overheat, and melt my plastic fittings. Water will spray out and only then will the pressure drop enough to shut down. When it's in this dry run situation the pressure gauge reads approx 26psi even though it's not moving any water. I suspect the pressure tank is interfering here as it is set to just below the cut in pressure (also close to 26psi). Any advice would be helpful. Thanks!
