Thanks George. Actually, my sump is more like 24", but I think you are nevertheless correct. I checked around locally and it seems my house is situated on top of a fairly high water table. So it seems pretty common in my neighborhood that the sump would fill up quickly as it has been doing. I guess my concern now is that the pump has been in overdrive lately and the motor may burn out more quickly than usual. Does anyone know the standard lifetime of these sump pumps? Mine is a Sears brand so I have no idea how long I can expect it to last. Anybody with words of wisdom?
