    Re: thisnewowner's Plumbing Questions.

    I can't make out the big picture...but you have things labeled 'vent' which are horizontal... You can't do that!

      2) Allowable Materials.

      (a) When installing fittings or piping for renovations or alterations within an existing soil stack, waste stack, vent stack or drain, the fitting or piping shall be of the same material as the existing stack or drain and be compliant with a joining method outlined in 248 CMR 10.07. Exception: In new residential construction cast iron pipe may be used exclusively with PVC for sound reduction.

      I would cut everything out and start over.

        Yes, I knew that. This old house has several places mixed PVC with CI. Inspector saw those mixtures and didn't say anything last time. It is not practical to follow that rule in all cases.

          To be honest, I doubt there is a pro here who would try to make what you have going on work. Your best bet would be to cut everything (new and old) out about 5' back and start out clean.

            Re: this U turn vent is good or not?

            So I can use two 45-degree or 30 + 60 degree to turn 90 degree as long as i am not put those two fittings together? It looks to me I used one 90-degree fitting and that is the place against the code. The U turn is a big U turn.

            following is from code as well but it is too general and I don't know how to interprete it:

            No fitting, connection, device, or method of installation that obstructs or retards the flow of water, wastes, sewage, or air in drainage or venting systems where the obstruction results in flow resistance that is greater than the normal frictional resistance to flow shall be used unless otherwise specifically indicated elsewhere in 248 CMR 10.00.

              It all needs to be cut out and re-done. It's a mess. If you are not going to do it correctly then ignore the advice of licensed professionals and just slap an AAV and a couple Fernco's on it.

                I always respect professional's advice. That is why I came here. I will redo it without that U turn but I may not cut the vent all the way up to replace the entire vent system and the entire drain system.

                That requirement about using same material cannot be followed in all cases. I have seen lots of pvc-CI connections here when we shopping our house. This house we bought 2 years ago have at least 3 places are pvc-CI connection. I don't think all of them are DIY project.

                I want my project has a good result. Professional's advice is the essential.

                  So are you saying that it can't be done or that you don't want to do it?

                    Everything I see is wrong. Time to call in a professional.

                      Sorry to say, I think you are somewhat confused and might need some professional help. Hope it works out for you.

                        Regardless of the mixed materials, you are trying to make your new DWV work without eliminating your existing DWV. In the long run it will be much more work and be done improperly. That is probably 1/2 a days work for a pro to do it right versus a couple of weekends of your effort to do it wrong.

                          Yes, I will eliminate the existing DWV. Please see this photo. The blue colored will be cut off and the new DWV will be look like the red lines.

                            That is a much better start but we will need to see where you go from there. The 1.5 galvanize vent should be cut under the floor leaving enough room to tie it back in with a NH coupling or similar (check your Code).

                            What fixtures are you venting with the 1.2 vent?

                              It is for first floor bath originally (before I cut). Now I plan to add basement counter sink vent into it. So It will the vent for a bath (first floor) and a counter sink (basement). On the left end of the basement room is a 3" pipe from the ground. I plan to connect the bath to it. The counter sink drain and the new vent will end with that 3" pipe as well.
