One other thing to note, is that the wire going to the fan slips onto two thin prongs. The connection is not very snug or tight. I can't remember for sure but I am 99% sure that the wire had come unplugged from the fan itself but both were fully submersed in the water. It's the same end you find on a cord that plugs a ghetto box in, two little pins.
Not sure if that means anything to you electrician types out there or not.
