Here in california nobody knows what a sump pump is - probably would go to the sex shop looking for one. Since I hail from Wisconsin, I remember. I also noticed a few 12 volt auto battery units in the Northern tool catalogue that seem reasonably priced. If you have kids however, you can buy a simple hand pump and teach them that paying to burn calories at the gym is foolish when THEY can be your back up 12 volt battery and pump. A few hot dogs or pizza slices in them as fuel can pump thousands of gallons of sump water. Might need a whip or chain to get it all to happen however.
