what size vent connections are on top of the chair carriers?
I have never seen the brand you mention, Is the vent on the carrier baffled in any way to receive waste??
I doubt it!
wet venting SUCKS anyways!
and even if you were to attempt it you would have to have at least one pipe size larger than the fixture you are draining meaning the carrier vent fitting would have to be at least 3″ wouldnt it ??
damn wheres Nick Hydo?
He’ll straighten this mess out.
