    Default Patina

    I came across a couple of fittings today that are part of a forced water boiler system that had a "patina" affect. Does anyone know the cause of this?

    Overheating?

    Excess flux?

    Failure to install the insulation right side up ... oh, wait, that's a different item I was going to ask you about , you did write up the exposed paper facing of the insulation and the fire hazard it represents, I am sure.

    There were only 2 of these shutoffs that had this issue, if it were overheating, I would expect to see it on all the shutoffs but that is a possibility.

    Yes, paper facing is easy to detect and report, it's the unknown and less obvious issue that I'm after.

    Jon,

    I'm referring to plumbers overheating them with their torches, not overheating from water, etc.

    I think that was caused by leaking drain cocks for winterizing and possibly a low PH. Was it well water.

    It was well water however these lines are part of a boiler system, not potable water.

    If there are no filters or softener then low ph is possible. google it and you'll see what it can do to pipes.
    The water in the heating lines would still have come from the well.
    Why would you need the drain cock on a heating line shutoff. Did it go to an addition.

    It does go to an addition. I'm not sure why they would have those either.
