    Default 4 inch drain pipe cracked

    How do you remove the pipe from a joint to replace it with pvc?

    Cut the damaged section out, then use no hub couplers to piece in the repair. These are made for both plastic and cast iron pipe, make sure you purchase the correct one.

    I'm assuming it's cast iron first cut out the bad section.Make sure there is no raised lettering if there is you must file or grind it down.Next you will need two couplings make sure it's for cast to plastic.Then just slip them on and tighten them up.
