Was gone for a few hours and when I got home I could hear a odd noise. So I walk back and into the laundry room, to discover the odd noise was the back up sump pump. It wasn't keeping up with what was running into the sump. I set another pump in the crock and in 5 minutes or so the water was at a dribble. If I had not of had that back up pump I probably would have had several inches of water in the house. It seems the float on the primary pump had failed. This is a testament to the fact that no one needs 'a' sump pump, ya need at least two.
