Thanks for the help.
The city just installed new sanitary sewers in my area. I am about to solicit a contractor to connect me to the stub. I have two drains to connect. 1) A 3" PVC line that drains the kitchen sink, and the washer in the basement as soon as I plumb a line to connect it to the PVC line. 2) a 4" cast iron (I think) line that drains my bathroom toilet, bathtub, and shower. The bathroom vanity drain disappears into the wall and I can't find where it drains.
My questions.
1) Am I correct that the drain is cast iron? (see photo)
2) Does the vanity drain into the cast iron pipe vent? That is the only structure that goes near the wall where the drain exits the cabinet.
3) Where will the PVC and the cast iron tee together to attach to the stub? Any recommendations?
4) Should I have a check-valve installed in the line to the sanitary sewer to prevent backflow? How long before such a valve fails?
5) The house was built in 1956, so I assume the cast iron drain is 55 years old. Should I consider replacing that line? I read that life span for cast iron is 60 - 100 years. The line was never heavily used (2 people) and has never had any problems.
Thanks for your help and corrections to my amateur terminology.
