Hi I have a 1.5 inch tub drain I need to convert to a 2 inch Shower drain. The Sanitary Tee has a 2 inch coming straight up from the ground then going straight up to a 1.5 inch vent pipe and branching off to a 1.5in tub drain. I need to do this to Code here in California. This is a concrete slab and pipes are underground. What is the proper way to replace the Sanitary Tee for the 2 inch shower drain and 1.5 inch vent. Thanks
