Q. Bob, You did an inspection for me in Racine a month or so ago.  I have question I hope you can help me with.  We are considering hooking up a second dryer and I would like to know if both dryers can be vented out the same location in the wall or would it require separate vent pipes.  I considered finding a “Y” to install in the line going out of the house and connect both hoses to it. Thanks Tim

A. Tim. It is recommended not to do this. Each dryer should have it’s own exhaust. The reason is that the exhaust can back up into the dryer that is not running and cause rust and corrosion to the components not to mention Carbon Monoxide entering the basement if it is a gas dryer. Another reason is that if the dryers are both running, a restriction will occur at the “Y” (2 hoses merging into 1) The restriction can cause the dryer to run longer, clothes dry slower which is a waste of energy also. The dryer can overheat and possibly cause a fire. Don’t forget to use rigid metal pipe whenever possible (no vinyl). The pipes are easier to clean and is fire rated.
