Polybutylene pipe is a plastic pipe that was used in residential water supply systems. It was very common in the Tucson area from about 1982 until 1997. Polybutylene pipe became the subject of a billion dollar class action lawsuit. The pipe had an unusually high failure rate and would leak without warning.
