Abstract Electrochemical tests, as well as surface and chemical analysis were used to investigate the cause of pitting failure of copper tubing in a drinking water distribution system. The results show that localized pitting was the cause of failure and copper corrosion problems were observed under a green deposit. The pitting corrosion was associated with the Cl$^{−}$ and SO$_{4}$ $^{2−}$ ions introduced by the water softening treatment. These ions promoted the corrosion and the influence of Cl$^{−}$ ion was much greater than that of the SO$_{4}$ $^{2−}$ ion.
