I am remodeling a first floor Master Bedroom in Texas. The existing plumbing is buried 16-18" bellow the finished slab. There are two existing 3" branch lines connected to a 4" main exiting the home. (All shown as black lines). All turns will be gradual bends with Wye's (or combination Y-1/8) for connections to the 3" lines. All connections are horizontal.
The new fixture arrangement does not have any walls above the drain lines to direct vent. The proposed layout has a 2" dry vent for the lavatory sink providing a horizontal wet vent for the new 3" branch.
House is in Austin TX. Code is 2012 IRC and 2012 IPC

- Does this configuration meet horizontal wet venting of a bathroom group?
- Does the single 2" vent provide sufficient venting per code or do I need to run the 3" line all the way to the vent?
- Any issue with the bathtub and shower drains making these changes of direction?
