  • Does 1980 PVC pipe fit up snuggly with 2009 PVC pipe

    I have to cut a piece of PVC pipe that was put in in 1980(black) and I need to glue in a coupling(white bought from Home Depot). Will the two fit together?? Has the OD changed over the years??

    If it's black, are you sure it's PVC?

      Should be the same O.D. for abs, or pvc dwv. Use universal glue or transition glue when mixing different pipe types and fittings.

        As far as I can see these are two different questions. Yes, to the title question. In Canada 1980 PVC will fit today's PVC.
        If it's black, I would think that it's ABS pipe, not PVC.

          The connection should be made one of 2 ways: (In IL)

          1. A male and a female threaded adapter
          2. No-hub coupling (preferred)

          In IL, attempting to solvent weld pvc to abs does not meet code.

          Why not just get an ABS coupling?

            call a plumber. you are out of your depth. you will likely make your repair and be quite pleased with yourself, not knowing that you have left a nest of thorns behind you for someone else to deal with.
            This is my reminder to myself that no good will ever come from discussing politics or religion with anyone, ever.

              Do yourself a favor and use a mechanical coupling.
              Use a no hub band that looks like this..

                I think it would be important to know if this pipe is a sewage or pressure pipe. The slip coupling would be fine for sewage, but for pressure would probably push apart.

                This black pipe could also be poly pipe which does not use solvent welded fittings.

                  What size (inside diameter) is the existing pipe?
