experts scratching their heads

than 70 years, and is perceived as the industry standard. Consumer
confidence in copper is high, and the material has an earned reputation
Copper tubing failure is rare. But corroding copper tubing has recently
been reported in cities as far apart as Phoenix, Ariz. and Andover, Mass.
Other cities reporting problems with pinhole leaks in copper include
Saugus, Calif., Lima, Ohio, and Jacksonville, Fla. In Jacksonville, the
problems were so serious that the city, in an unprecedented step,
banned the use of copper for residential water supply piping.
