    Default PVC cold supply piping

    Inspecting a mid 1980's house tomorrow that has white PVC cor the cold piping, CPVC for the hot. Is this not allowed, was it always not allowed? Besides DIY issues, what are the potential problems (breakage, etc.), should the house be re-plumbed if there are no apparent problems?
    As always, Thanks.

    Here in Illinois we are allowed to use PVC on cold water supply only. But most counties, towns, and cities will not allow it. Best to check with you local plumbing inspector to see if it is allowed in that town.

    If you're state licensure board is like North Carolina, don't say it was against code unless you can site code chapter and verse.

    As for what Cities, townships, and counties they are allowed to make the code stricter but nothing less than the the Illinois Plumbing code.

    Out of curiosity, did you attempt to contact the local building permits office?

    I was just curious, Ron has supplied an abundance of material from the Illinois Dept. of Public Health.
    Does the Illinois Dept. of Public Health administer, interpret and enforce the building codes in Illinois?

    Not applicable, the City was under the County building department at that time and there were basically no rules enforced. Build whatever you want!!

    I hear home owners say that all the time to me, and I hate to say it they are full of BS. If you are building in Incorporated areas where the county is in charge, they have county building , pluming and other inspectors. And if the county does not have any I can tell you the state does.

    All states have or follow a plumbing code and the homes need to be built to code.

    The key is where you say "... there were basically no rules enforced ..." being enforced or not being enforced does not mean that rules did not exist. Enforcement is a different subject. Rules at time of construction is the question and the answer.

    The use of PVC and CPC in practice revolves around the use of chlorination in the water, the temp that the material will be subjected to and the pressure the material will be subject to. When the use of CPC for all supply lines was required just mane it easy easier to inspect and upgraded the cold lines to a higher specification (no harm no foul). The big basic issue is about expansion of the pipe and joints under heat.
