    I have a house in Unicorporated Cook County Illinois . It was built to code in 1993 where requirements fo the waste pipe was cast iron. My question . Our cast iron pipe in the basement has cracked . Would replacing the cracked section\ with sch40 PVC pipe be in accordance with the Cook County plumbing code.? The home is a 2 story .
    Thanks
    Joe

    Joe, your best course of action is to call the county code office. While certainly there may be a plumber from Cook Country that frequents this forum, we readers are from every corner of the country and even some for Canada, the UK, and Australia.

    Current Code allows pvc in unincorporated Cook County, IL

    Not exactly sure when, but the code does not allow this substandard pipe in SFRs.
    So, yes, in your situation this would be allowed.
    Just remember, the only "long term" advantage of pvc is that the smooth interior lessens
    the likelihood of any material sticking to the pipe walls, provided the pipe is properly installed.
    You really should follow the manufacturers recommendations and ream both the inside / outside
    diameters and not over-glue, nor under-glue.

    The main point is this: since it is very likely the pipe will be rodded at some time, there is the
    increased chance of the pipe being rodded through. Even if this isn't the case, the smooth interior
    now becomes a very rough interior which is much more likely to catch hair and fats, oils, grease and
    anything else that finds its way into the pipe.
    That said, you really should post signs for the roto-rooter types which would probably dismiss
    such conditions as problems. It would be best to jet-rod, especially this section of pipe so as
    to avoid any future problems for yourself, or any prospective new owners. Make sure to use the
    correct couplings for tying the two materials together ! ! !

    Best of luck

    Gary, engaging in a bit of hyperbole, aren't you? Maybe a U.A. local 130 plumber?
    1. PVC and ABS are NOT "substandard" and are the material of choice in MILLIONS of homes all over the country.
    2. I have NEVER "rodded through" ANY plastic drain or sewer line
    3. ALL of the municipal sewers I have seen installed in the past few decades have ALL been PVC
    4. Snaking a plastic line does NOT create a "rough surface"
    5. There is absolutely NO reason to post a sign saying he has a section of plastic pipe.
