I can, but not sure it would cut out too much of the length. Right now, the outlet is about 1 ft off the ground, does a 90 degree bend down goes about 1.5 ft down, another 90 degree bend, then goes about 8 feet or so. Another 90 shooting up then another 90 bringing it parallel to the ground. Finally, there's the standard outlet with the flapper that vents outside.
So the way I see it is that I have about 30 ft or so of vent between the dryer and outside, given each 90 adds about 5 ft of restriction. If I went up the wall and through the attic outside, I could possibly reduce that to about 20 feet using the same 5 ft/90 degree bend. Does anyone think it would be worth the trouble of doing that? Worse case, I could remove the one in the attic if it didn't work out, but don't want to have to go through the trouble if there's another option.
