What is polybutylene system?
Polybutylene is a form of plastic resin that was used extensively in the manufacture of water supply piping from 1978 until 1995. Due to the low cost of the material and ease of installation, polybutylene piping systems were viewed as “the pipe of the future” and marketed as the best thing since sliced bread. It was used as a substitute for traditional copper piping. It is most commonly used where residential construction was heavy through the 1980’s and early-to-mid 90’s. It has been estimated over 40,000 homes had this piping installed throughout San Diego County during that period of time.
