Sorry to hear about the flood. But it sounds like you have things under control.
Had something similar happen years ago when we lived in the suburbs of Chicago. We lived in a tri-story and I went down to the lowest level in my bare feet one day after some torrential rains. Stepped into about 2 inches of water. Out of frustration I went to check the sump pump, which was quiet. Figuring it had burned out, I kicked it in frustration only to hear it purr into life. Apparently the float ball had gotten jammed just below the switch.
The lessons I learned from that were:
(a) don't ever put anything important less than 12" off the floor.
(b) once you get the water out, get fans, blowers and the like to get it as dry as possible as fast as possible. If you get mold growing it will be a nightmare forever.
(c) kick the sump pump once in a while.
I live in Texas now where we don't ever have to worry about floods
