I want to put a washer and dryer in my basement, but will need to do the plumbing from scratch. There is a floor drain in the area (about 5 feet away) where the furnace drains. It there any way to tap into this? I realize I will probably have to break up the concrete floor and dig to the drain. Is this going to work? Also, what about venting? Will I need to run a pipe to the roof, if is that floor drain already vented somehow? {e-mail removed}. Thank you a million times!
