I have a Grundfos submersible pump that I installed last may. It has a built in check valve, and it has worked fine until yesterday. Yesterday evening my wife tells me she flushed the commode and it sounded as if it was blowing up. She said she flushed it again and got a shot of dirty looking water. This morning she was adding water to the pool and got air and another shot of dirty water. I turned off the pump and drained the pressure tank. I put the drain hose into the floor drain and turned the water on and walked away. The hose was in the drain to the bottom, 17 inches deep. When I came back there was water on the floor and the hose end was several feet from the drain.
It look like the hose had blown back out of the drain and water had been sprayed on the walls.It appeared that there was alot of air at the end of the draining and the hose blew back out of the drain. The tank pressure was 35, so I bumped it to 38. (40/60 pressure switch)
I went to the well and measured down to the water level. The well is 80 feet deep, cased 60 feet(6inch case). The pump is 44 feet below the adapter, and the water head is 30 feet above the pump. I watched the level in the well through several cycles.
It never dropped below the pump. It appears that I am getting the most air when the pump first starts. After the pump stops and things settle down, I can bleed the outlets and things seem to be fine until the pump starts again. Does anyone think that the check valve at the pump is not working properly. Any ideas about what my problem could be? Any help is appreciated.
