Well Problem - Pump will not turn off
Hello, I need help diagnosing a well pump problem. I know almost nothing about well pumps, but I hate paying repairmen for anything, so typically I try fixing problems myself.
We have a well for our outdoor water supply. We get excellent water pressure, but the pump will not turn off. I have to plug in the pump when I want to use it, then unplug it when I'm done. The pressure tank builds pressure while running, but drops to 5 - 10 psi immediatley after unplugging it.
There is a valve in the supply line that runs to the pump (check valve?). I originally thought this valve was full of sediment and allowing water to back flow, thus causing pressure loss when the pump shuts off. I took off the valve and cleaned it out, and it did contain sediment. I reinstalled the valve, primed the pump and started it up. It worked pretty well for a few days; however the pump still ran a few minutes every hour even if we weren't using the outdoor well water. But a few days later I woke up and noticed the pump had been running for quite a long time. When I went to the cellar, I found quite a bit of water around the tank.
Now I'm back to plugging/unplugging the pump when I need to use it, which is a pain.
Thanks in advance for your help!
