My son bought a new home with a grinder pit and rough -in plumbing under the finished concrete. There is a 4inch vertical pipe out of the floor, a 2 inch pipe vertically out of the floor, and a two inch pipe horizontal with a cutout in the concrete. The vertical 2 inch pipe isn't located in the wall? I am assuming they are using this as a wet vent for the sink and also a vent for the toilet? The shower is close to 6 feet from this two inch riser. It probably will need its own vent? If I put a 2 x 11/2 inch sanitary tee in this riser, can I square break above it to get the vent back into the wall? Also can I tie this vent, the one from the shower and the one off the pit together as long as they go to the roof?
