Bought a new washer+dryer. Old washer+dryer are still working fine, so I figured I will keep the old dryer and just dispose of the old top load washer (the new one is a nice front load). They're both electric, so I don't have to worry about gas plumbing.
Do I need a separate vent pipe for each dryer? Or can they just "share" a single vent pipe, via a "Y-pipe?"
