Sounds like water supply is not up to pump draw. I got my new bore pump back in and going last night. Boy, did I miss that water. Our boreman said that he sometimes has to put restricters in the line to keep pump pressure up and limit the flow of water. You could try that. I fitted a Franklin pump assy this time. My high pressure is 65 psi and low is 45 psi.
