Recently, Wisconsin has experienced significant amounts of rainfall in very short burts. Up until the other day, my trusty sump pump kept my basement dry as a bone. A massive power outage during the last storm, however, rendered my sump pump useless and my basement flooded. The only good thing was that I didn't have much down there, and I had time to get it upstairs. The basement drain was free, and the water, once it made it to the drain, drained nicely.
In response to this near tragedy, I've looked into battery backup systems. Because we did not get our power back for over 24 hours, however, a battery system in a similar circumstance may have only prolonged the innevitable. I've seen some manual systems (not human powered) offered. Does anyone know if they work?
(Note: it occurred to me after the fiasco, that all I needed to do was create a siphon from the sump hole to the basement drain and I probably would have been fine).
