Can I use a Fernco coupling to connect the new PVC to the old underground
cast iron sewer pipe?

If not, how is that type of connection usually made?


What do local codes say about your use of PVC in sewer run that is
presently cast iron ?

Would there be a problem obtaining cast iron piping and patching
whatever pipe has given way ?

Since you are already digging up the pipe why not replace the
entire run, as it gets expensive to dig it up and repair it 4' at a
time...
