          Tie the Lav. line into the tub line and use a 4" double san. tee.

          Not combination.

                From what the drawing looks like, it will be fine. 4" vent is more than sufficient for two bathroom groups. If the toilets are blow out type you can not use a double san tee.

                  The best thing to do is ask the code official in your area before doing the work so that you have to only do the job once. sanitary tees are going to vent better than wyes but you have to know what kinda toilets that are going to be installed to see if it will be permitted . at least by our code

                    thanks for all your answers so far
                    the toilets are regular toilets not pressure assisted or blow out type
                    so it seems like the double san tee is better

                      good luck when it comes time to snake/ auger that back to back toilet with a san tee.

                      a figure 5 or a twin figure 6 with baffle and cap the top of the riser, would be a better choice.

                      you can look up these fittings at www.tylerpipe.com

                        Oh shoot Rick, let him do it his way; when it backs up it'll be the perfect opprtunity for you to haul the k-60 up to the roof vent.
                        This is my reminder to myself that no good will ever come from discussing politics or religion with anyone, ever.

                            What's the difference between these and a double wye 1/8 bend? Wouldn't these fitting cause a venting issue?
