We e relocating our laundry room. Whats the maximum length for a dryer vent?
A. First, consult the installation instructions provided by the dryer manufacturer. If this information is not available, the International Residential Code states that the duct (not including the transition duct from the dryer to the wall) should not exceed 25-ft. Moreover, this maximum length should be reduced 5-ft for every 90-degree bend and 2.5-ft for every 45-degree bend.
