Remodeling bathrooms - drain and vent question
Posted by Brian on June 17, 2003 at 11:21:17:

I'm remodeling 2 bathrooms that are back to back and mirror images of each other. My plan was to use 2" pvc to drain both tubs and both vanities. My question is, is a 2" pipe large enough to drain all 4 fixtures? My other question is, do I need to put an additional vent between the tubs and drain which is about 22" away. (Please see attached diagram)

Thanks in advance.
