So, let's play a guessing game. I flipped the power off on this baby last night, and was greeted with a lot of water on the floor. I bet no-one can guess wtf happened, and no, it wasn't the surge volume of the tank - the sump can absorb the water drop from the tank very easily. This problem can be fixed pretty easily (and will be, today), but I'm actually pretty tickled by the unexpected nature of the problem.
