    It was never an issue in my early days, but I remember examining the sch 40 Slip x MPT adapters and pondering which ones looked more likely to endure, because they all did not have identical geometry. Better a thick wall and a broad shoulder, and maybe not so many threads, which was basically saying "skip the pondering and start using sch 80 TOE nipples."

    {It might be that threading male CPVC into female metal runs into expansion/contraction problems with hot water}

    I do it all the time, just have to be light with the pipe dope and make sure you start it straight and not cross thread.

    I am Irish though...
