@Dan Holohan I remember you talking about having this problem a while back, no?

Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

    I saw that on NBC news last night... scary stuff.
    Is it bad copper, bad water... or both?

    Are they using L copper for domestic instead of M? We had problems here in Mass years ago, and it became the law of the land that if copper for potable water, L it is. M is still good for heating, and has really never been an issue in a closed system

    I've heard of sewer gas eroding copper dwv pipe if I recall.

    Another culprit for copper fail can be traced to acid/flux ending up inside the pipe. Never really flushes out, and eats it way out

    Bill, i read that also. The cold line gets it worse, since the hot water kind of softens it up

    I think it was late 80's here that it was at it's worst for pinholes. Crap copper pipe springing leaks in new homes within a year

    I have had pinholes from flux in the cold water pipe only as mentioned above. House was 10 years old and popping pin holes. That's why I use NOKARODE.

    Nokorode makes water washable flux now. Amherst Ma has bad water. They use K tubingup there and still have problems.

    Long Island sounds like a different problem though
