摘要

The theory that "pitting water"--nonaggressive water with high alkalinity and conductivity--is thernprimary cause of pitting of cold water copper domestic piping appeared in the literature in 1971. Thisrntheory gained popularity for a period of time. However, the accumulation of further evidence showed thatrnthe theory was non-predictive, and its original proponents retracted it in the 1980' s. Nonetheless, "pittingrnwater" is blamed for pitting of copper domestic plumbing with disturbing frequency more than a decadernafter the original proponents of the theory withdrew it.rnA critical review of the literature is presented showing how the "pitting water" theory arose and tracingrnthe accumulation of evidence that invalidates this theory. The case is presented that the concept ofrn"pitting water" is not mechanistically significant, and that most, if not, all pitting of domestic copperrnplumbing attributed to "pitting water," is in fact of anthropogenic (human-caused) origin.
