I need a reliable backup to my sump pump. I have a 12V battery backup pump from Sears that keeps killing deep cycle batteries. It boils off the water at a rate that you must add distilled water once a month.

I saw a water powered backup sump pump on This Old House. It uses an eductor. This is nice because I have reliable city water...and no batteries to die out. Does anyone have experience with one of these and perhaps provide a source?

thanks in advance...Jeff
