Long story short. I had a leak under my house. I lost enough water to run my pump dry. I found this on the flange coming out of the pump. The flange on the incoming side of the pump is fine. Can someone help me identify what caused this. The part of the flange that is shiny, is pitted and deteriorated.
Thanks for any help.
