In response to Re: venting my dryer
It depends on which end needs to be reduced. Once the pipe leaves the dryer, it cannot be reduced in size, since it would cause back pressure, overheating, and poor drying. But you can install a 4x3 increaser on the fryer, if the dryer is 3" and the pipe is 4".

: Is there any way to "reduce" a 4" venting pipe to 3"? Thanks for the help.
