The best you can do is what deadrock said. For the future, invest 20-30 bucks and get two Pentex B11 (battery opperated) pumps. Make sure they're the ones you leave plugged in and only turn on when the power is out. I invested in a whole house generator, not just for the tank, but that was a primary concern as we have had power outages for 4-5 hrs. Good luck.
