New dryer coming. My vent goes down into the crawl space. Make a 90 degree turn. And then runs out 6 ft to the outside. The vent cover broke so it is easy to see in the tube with flashlight. I run a log pole through and it goes all the way through. I can see all the way out the other side. I don't think the guy who did the work ever hooked it up. So for the past 11 years, I think (don't know) that this has vented under the house. My house under pinning is made with 1x4 inch pine boards gapped one quarter inch. I want this house to breath and there is a ton of air flow beneath it. The crawl space is also about 30 inches so plenty of room. I wonder if I can just let it vent to the crawl space since I have so much ventilation. Thoughts? Suggestions?
