Polybutylene pipes

Polybutylene pipes are a type of plastic plumbing material once popular for residential water supply lines. Made from a durable, flexible polymer, they were favored for easy installation and low cost. However, over time, many polybutylene pipes became prone to cracking and leaking due to chemical reactions with chlorine in the water, leading to widespread plumbing failures. This has resulted in significant home repair costs and insurance issues. While some remain in service, many homeowners have replaced them with more reliable materials like copper or PEX to ensure long-term durability and safety.
