Protecting Homes from Unannounced Polybutylene Ruptures
Polybutylene (commonly branded as Quest) is a grey plastic plumbing pipe installed in millions of American homes built between the late 1970s and mid-1990s.
Over time, chlorine and oxidants in municipal drinking water cause polybutylene pipe walls and acetal plastic insert fittings to micro-fracture and flake from the inside out.
Because degradation occurs internally while the pipe exterior appears normal, polybutylene pipes frequently suffer sudden, catastrophic splits without any prior dripping or warning. Replacement with modern PEX or copper is the only permanent solution.
Ideal Applications:
Homes constructed between 1978 and 1995 containing grey plastic plumbing, homeowners facing insurance cancellations or denial of coverage, and properties undergoing sale or appraisal.
