Corrosion Failure of Copper Piping
Pitting Corrosion and Leakage observed in Cold Water Copper Piping in Residential Home
Macroscopic Examination of Pits and Metallographic Cross Section Analysis
Scanning Electron Microscope Examination / Energy Dispersive X-ray Chemical Analysis
Failure was related to prolonged period of stagnation after completion of the plumbing installation and occupancy of the home. Stagnant conditions allowed settling of sediment deposits setting up local differential aeration cells.
