Polybutylene pipes were widely used in residential homes from the late 1970s to mid-1990s as a cheaper alternative to copper pipes, but they have been found to be prone to cracking, rupturing, and deterioration over time. This can cause water damage, mold growth, and costly repairs, as well as making it difficult to obtain homeowner's insurance. Homeowners should have their plumbing system inspected and consider replacing polybutylene pipes with a more reliable system to ensure the safety of their homes and families.
