Home Inspection: Polybutylene piping

When was Polybutylene piping used?

Poly. piping was used from 1978 to around 1995 as it was thought to be the pipework of the future. Due to the low cost of the material and ease of installation, polybutylene piping was viewed as a cost-effective substitute for traditional copper piping.  Unfortunately, they failed to stand up to the test of time. Nowadays, polybutylene pipes are no longer accepted by the US building code and have been conceptually replaced with cross-linked polyethylene piping.
