I am removing a vanity and adding a corner sink to the opposite side of a small bathroom. Will the attached configuration work? I know the vent attaches to the main vent below the sink but I can't see why that would matter in this case since nothing drains above it (single story home). Plumbing not labeled NEW in the drawing is already in place and works great thanks to previous help on this forum. The sink was not thought of at the time or I would have just added a 4 way where the standpipe connects.

Also, could you please let me know what the rough-in dimensions for the drain on a corner sink are (the drain is about 6.5" from the wall)? I appreciate any help offered.

The revent ties in six inches above the flood level of the fixtures being served.

Normally that means at 42" off the floor.

When you have your sink and cabinet, that will tell you rough in height.
Typical RI is
30" cabinet, 18"
32" cabinet, 20"

Thanks for the info. In the drawing, couldn't the angled sink vent be considered a separate parallel drain stack if it used fittings for a wet drain? I can't seem to figure out how the venting and draining would be different than if a just connected to a 4 way at the standpipe connection (I am sure I missing something but can't figure out what).

Due to electrical and other framing issues, I can not get the vent connection above the sink. Are there other options?

I think the reason for requiring the vents to connect higher has to do with what happens if there were to be a clog at B or C.

I believe you could follow the blue path and be OK for that section.
