Backflow device an alternative to venting?
Posted by Geoff on March 04, 2002 at 18:06:59:
I'm putting a kitchen in my basement, and although the sink will be located right next to the main DWV stack, there's no way to hit a vent pipe anywhere. Can any sort of backflow device be used instead of venting? I would think that the trap stops gasses from entering the room, and the backflow device would stop fluids.

Alternately, can I vent through a wall (it's a walkout basement) or use a loop vent into the same stack (I'm not sure I understand the physics of loop vents.) Thanks for this great bulletin board.
