In one statement you said it pumped up to 60 psi. Then you say it runs forever until you let it sit. What do you mean by that?
Problem is that if the pump sits for 15 minutes. The pressure gauge remains at 60 psi....seems not to lose of pressure. I will turn the water on and the pump will kick on at 40 psi and will slowly start dropping pressure. By shutting off the water and letting it it repressurize, bleeding the air out with the faucet, the pressuse will build itself back to normal. Will run forever until I let it sit.
