Hi, Thanks for you timely response.
I you have a well vented crawl space under your house, why can’t you vent your dryer underneath your house.

Oh, but you can! If you don’t mind mold, mildew, rotted floor joists, caved in floors, and chronic illnesses from all the gookus in dryer exhaust. Also, the US EPA has identified the fragrances in fabric softeners as particularly potent source of allergens for many people.

I dunno, dryer manufacturers come up with these silly venting requirements because they have this crazy notion that most people don’t like this stuff. Go figure!
