We recently purchased a house in Massachuetts. It was built around 1930, most if not all of the pipes are cast iron, no pvc. One of our projects is moving the stack 2 ft to the left, and swapping places with the toilet and vanity sink on the second floor. We are doing this because the stack is pretty much blocking the entrance to the kitchen. We have to go around the wall covering the stack by going up two steps and down two steps. Here are what we are planning to do:
-Remove existing sink and toilet
-Move the toilet about 3 ft to the left with a new flange and 4" PVC pipe
-Put in new 2" PVC pipe for the vanity sink, about 3 ft to the right
-Make sure the CI pipe is supported
-Cut the CI pipe section on the first and second floor
-Put in a new 4" PVC (2 ft from the original spot)
-Put in insulation as sound barrier (living room is right under the 2nd floor bathroom)
-Connect the new PVC pipe to the CI pipe in the attic (instead of drillng a new hole, the connection will look like an inversed "L")
Would this work? Any problems? Suggestions? Can we connect the PVC pipe to the stack at a right angle?
