Product review (5 stars): This may be the solution!
I live in Alaska and have been plagued for years by the threat of frozen pipes in the laundry area, largely because my house was poorly designed for this climate. I've become rather adept at thawing pipes with the hair dryer, have occasionally been forced to call a plumber ($$) and resorted to removing the drywall behind the dryer to provide access to the problem area. I finally got fed up with the situation during a prolonged cold spell last winter and vowed to tackle the issue once and for all. After some online research I decided to give this dryer vent a try...nothing ventured, nothing gained, right? It was easily installed during the fall and I eagerly awaited the opportunity to gauge its performance. It's been good and cold for the last few weeks (0 this AM). Lo and behold, the inside of the dryer no longer feels like a refrigeration unit and the vent is not hemorrhaging frigid air into the laundry area thereby threatening to freeze the pipes. I am cautiously optimistic my problem has been solved (and for less than $20.00 including the caulk!). I highly recommend this product!
