Polybutylene Pipe was manufactured for installation in the US from the late 1970s to the mid 1990s. Polybutylene piping was installed in residential, commericial, industrial and municipal piping systems. Polybutylene pipe was mainly used for the piping of potable water. In the US, the piping was pulled from the market after a series of lawsuits resulting from catastrophic pipe failures occuring nationwide. However, in Europe, polybutylene resins were modified and polybutylene remains a popular product today.
Polybutylene pipe failures can be related to chlorine content in the water, oxidants in the water, improper installation, too much water pressure and many other factors. Failures begin with micro cracking of the pipe and eventually to a leak. Failure normal occurs from the inside out, however, can be accelerated by factors such as ground settlment and poor bedding material.
