I am putting a dryer vent up through a wall and out
through the sill. There is only 3.5" space in the wall
so I want to put in a 3" aluminum dryer vent and a
4"-to-3" converter on the dryer. Is this ok?
Otherwise, is an indoor lint-trap style vent ok? I
use the dryer rarely. Thanks,
Can't you flatten the pipe a bit? It would then retain roughly the same
cross-sectional area. I really wouldn't want to choke the dryer exhaust
pipe by going down to 3". I also wouldn't recommend venting to the
inside with one of those lint-trap things.
There's also no real reason you should restrict the placement of the
pipe to *inside* the wall.
There are two choices that are best..one, a premade section of pipe with the
same flow as a 4 inch round that is made for fitting between wall studs in
this type of install...or put the 4inch in and flatten it slightly.....and
re-drywall over it.
Nope...hate em..partucularly in the summer months..when you DONT want
another 3 gallons of water vapor added to teh air.
Actually the 6" di. is 87% as large as the rectangular, but a home dryer
has a 4" diameter vent anyway. Your rectangular is more than twice as
large as a 4" di.
...So, is there no insulation in the wall?
If the vent in that pic is 4" in diameter, then I want that pair of
those glasses for my pet hippopotamus.

I used a 3" vent pipe with a 4:3-inch converter to the dryer. Works
very well. The run from the dryer through the roof is about 13 feet.
You won't like the indoor lint trap. You'll get a lot of hot, moist
air pumped into your house and the lint trap will clog frequently and
you'll find lint coating your walls. Been there, done that.

Here is a test to see if your 3 inch "works very well". Disconnect the
dryer, climb up on the roof with a leaf blower and blow down your
dryer vent. Better yet, have someone else do it while you look at what
comes out of the bottom of the vent.
I think that most dryer vents are rarely installed to get maximum
performance and with least lint build up. The length of the vent from
dryer to exit point should be as short as possible. I had a hole
drilled thru my foundation to shorten the vent to about 8 to 10 feet
and the dryer time now takes about half the time. I had considered
the indoor but too many had discouraged me from doing this. Also this
works with water to pick up the lint and needs regular cleaning and
not to mention the additional moisture that is considerable. Most
builders will use the easiest route for a vent even if it means 30
feet or more of vent. If you consult your dryer manufacturer thay
usually recomend a maximum length for your vent for maximum
performance. A vent to long may also damage your dryer. The $100 I
spent for having a hole drilled thru my foundation for the vent was
the best investment I ever made.
