I have a gould jet pump that I use to fill a gravity storage tank. The system has been working fine for a long time. The problem is the pressure gauge will not drop to the kick in point so no water pumps. I have checked the gauge by unscrewing it and it seems to be working normally, I have checked the sensor line to make sure it is clear. There is a small pressure tank between the well and the storage tank but other than that it is open. Something is causing the pressure gauge to sense abnormally high pressure but I can't figure out what.
