    From the IRC.
    - P2904.5 Water-distribution pipe.
    Water-distribution piping within dwelling units shall conform to NSF 61 and shall conform to one of the standards listed in Table P2904.5.


    - TABLE P2904.5
    - - WATER DISTRIBUTION PIPE
    - - - (PVC is not shown on the Table as an allowable material)
    - P2904.4 Water service pipe.
    Water service pipe shall conform to NSF 61 and shall conform to one of the standards listed in Table P2904.4.


    - TABLE P2904.4
    - - WATER SERVICE PIPE
    - - - Polyvinyl chloride (PVC) plastic pipe

    The code reference, then, is "PVC is not allowed for use as distribution piping according to P2904.4 and Table P2904.5, IRC."

    Jerry may be right as to the code, but in NY the code also states that local law can over ride State and or National code. We have a large amount of CPVC piping and even some PVC piping that is labeled as use with potable water. That pipe in NY would not last one winter.

    *CPVC* is okay for use as supply/distribution piping.

    It's the *PVC* that is not.

    However, PVC *is* rated for use for potable water, which is why it is allowed outside for the water service pipe.

    Are you sure that *PVC* is allowed for supply/distribution piping inside?
