First of all, thanks to all who responded to my previous question about basement floors, your responses were extremely informative. Thank you guys, you're awesome!
I have one more quick question: I am installing a second dryer in the laundry room, and my HVAC guy tells me that he can't attach the new dryer to the vent for the existing dryer and will need to run a new separate vent. I'm curious as to what the reasons would be for not sharing a vent between two dryers. (The HVAC guy couldn't give me an explanation). Thanks!
