double drop jet pump

My pump will not turn on even when the piping run dry i.e, there is no water in the faucets. However, the pressure gauge on the pump shows 30 psi. After manually turning the pump on water starts flowing and the pump works until gauge shows 50 psi and the pressure switch turns it off. Then cycle repeats.

I would replace the pressure switch and the pipe connecting it to the pump housing. You can also try removing those parts and cleaning them. I suspect the pipe and maybe the switch have become clogged with sediment from the water. If you remove the tube going to the switch and can't blow through it then... it's clogged and should be cleaned out replaced.

Your pressure gauge may be bad or it also might be packed with sediment. The pump should still work without a good gauge but it should read zero when you're getting no water.
