Polybutylene pipe was once widely used in potable water distribution systems. However, problems occurred with the pipe's performance. It was claimed that the root cause of PB water pipe failures was in-service oxidative degradation of the material. These allegations ignored major problems with the installation of the PB water lines. This paper will show that installation issues far outweighed PB oxidation as the root cause of failure of PB water service lines.
