In Massachusetts is it Illegal to have pvc/abs in the middle of cast iron? It has something to do with difference in expansion. I have seen it done several times with out any problems.

our area, we transition rotted or split cast to pvc frequently, no issues with leaks. There are some buildings-that require cast to be replaced with cast. And in most others I choose XFR , it works well.

In Massachusetts it is illegal to do most anything but in matters of plumbing we will defer to 'packy' for the best advice to your question.

pretty much what they refer to is cutting a tee or a wye into a stack.
must be of 'like' material.
if you are replacing a section of stack and its fittings, you may transition to a different material by using appropriate methods.

Here, the inspectors prefer that you make a single transition. You can convert to a different material 'once', but not convert back to the original. "expansion differences" are immaterial for short sections and would not affect a cast iron installation at all, if a piece of plastic was installed in the middle of it.

in MA it is not a case of what the inspectors prefer, it is a case of what the 'low information' politicians have crafted for plumbing regulations.
