Hey you :) How did you escape my friends List :) LOL here is something interesting that you might want to share with your class, i had to come up with a solution to a problem, my Clothes Drier vent was causing me a problem, because the vent pipe is in the wall and exits out the roof, no way to route it outside, water was being condensed in the pipe, and draining down the pipe and wall onto my living room rug, the washing machine is in the Garage, but share the wall with my livingroom, the water was causing mold and mildew on the rug, I had to have a section of rug replaced, i thought it was a pipe leaking, had a plumber come out, and no leak was found, Hmmmm, found it when i took off the vent pipe and let the drier run :) check out this thread, Take care, Chellie
