We don't have to worry about flooding, but we have a sump pump in our basement that we've been watching very closely. They aren't meant to run continuously for 72 hours like ours has. We had one to burn out about 25 years ago and we had about a foot of water in our finished basement. We were lucky - there was a plumber at our neighbors house and he installed a new one for us before our basement filled with water like a couple of neighbor's basements did. Our insurance agent seemed so happy to tell us that we weren't covered.
We now have a back-up sump pump that runs on water pressure in case the primary burns out or we lose electricity.
