I've replaced my old bathroom ceiling/light exhaust fan because in the cold winter climate the moisture from the shower would collect in the duct, condensate, and then when the weather would warm up a little, drip back into the bathroom (sometimes pouring out). The new fan is much stronger, but alas, I have the same problem occuring (although less frequently this past winter). The duct travels a long distance across my attic to the south facing wall...(it's the only option, as the roof is steeply pitched. Some have said to disconnect the duct and let it vent directly into the attic, but that doesn't seem smart if there is that much moisture going up there, wouldn't it just collect all over the insulation up there? Any suggestions about what I can do to fix this problem would be helpful.
