The previous owner of my house had put in a 3" dryer outdoor vent. Why I don't know, perhaps this was the size years ago, but in any event I thought I would compensate for this by running all rigid duct from my dryer to the vent. I ran about 8 feet of 4" duct with 2 elbows: one at the dryer outlet in the back, and one at a 45 where the duct meets the outdoor vent. Then there is a 4"-3" adapter at the outdoor vent. Being the fact that I ran all smooth duct, is this enough to compensate for the 3" opening to the outside, or do I still need to get a 4" vent?
