My existing single bathroom sink goes from 1 1/2" trap to a 2"x3x3 tee into a 3" vert. drain/vent. I want to convert to double sink. Can I use (2) 1 1/2" p-traps and tie them into the 2" horizontal stub just off the 3" vent/drain? What are other options short of tearing into the wall? I'm in NC.
THanks a bunch for your help.
