You musta slipped on a rock in that creek, buddy, lol.
Anyway, as far as I can remember, I turned it on and the mirror did seem to fog up a tad, plus I was in a hurry, so didnt really test it before I got in... I got the breeze of my life.
Anyway, the water heater was flooded and it's now fixed, what had happened was we had a huge downpour and the rain bounced off of the ledge and into the vent, or at least that's what I gathered. The vent now has a sheild, so this shouldnt happen again.
