    Question Patina at copper water lines

    Okay... this is going to sound rediculous, but just want to cover myself. I had a home today where almost every connection on the copper water lines had a green patina, which I understand is most likely overfluxing or acidic water. I also had steel hangers, but, it was everywhere, even at the brass compression fittings under the sinks. I seem to recall (albeit not clearly) there was a bad lot of copper some years ago? Anyone have any thoughts? The home was built in 1973.

    Thanks in advance...

    The environment under the sink with all those off gassing cleaning products, cosmetic products - may have something to do with the formation corrosion/patina.

    Cheers,

    The value of experience is not in seeing much, but in seeing wisely.
