Vent requirement for basement floor drain (Canada)
I'm contemplating my options for locating a 2" vent in my basement which will serve my relocated laundry and floor drain. I was talking with a fellow at the local (independent) plumbing store and he advised that, in Canada, a floor drain does not need to be vented if it is minimun 3" in size, and the trap arm (pipe from the main drain to the trap) is a minimum of 16" long, maximum 12 feet with 1/4" per foot grade on it. Can anyone here confirm this? For what it is worth, my current basement floor drain isn't vented.
