I have a relatively new dryer (less than 2 years old) and it allows a lot of lint and hair to bypass the lint trap and exhaust outside. I have a short vent, as the dryer sits against an outside wall, and the dryer vent pops directly through the wall.
My problem: The vent sits about one foot above our wood deck, so all the lint/hair makes a mess of the deck. I thought about putting some type of extension on the vent to direct the vent undeneath the deck, but the problem is that I have a basement window right under it. We have a “look-out” basement and the set of windows right below the vent belong to my daughter's bedroom. If I direct the vent down I am afraid the lint/hair will make a mess of the window/screen or collect all over the underside of the deck. If I extend the vent sideways to clear the deck, I would need to use a sharp 90-degree bend and run it about 8 feet to clear the deck.
Is there any way to have some type of secondary trap outside to capture and control the lint.
Oh, and with three girls we do A LOT of laundry.
First off, the fact that your dryer is being vented so efficiently is actually a good thing. Thousands of home fires result from clogged dryer ducts. Getting that lint out of the house efficiently is very important.
The idea of a 90-degree bend seems to make the most sense, considering there's such a short distance between your dryer and duct. You probably have enough air pressure to push the lint through one 90-degree bend and out. I wouldn't add more bends than that, though. Adding a 90-degree curve is equivalent to adding twenty feet of straight duct in terms of the resistance needed to push lint through it.
