Szukam informacji nt wyroku, jaki zapadł po aferze COX w USA. Niby chodziło o złączki, ale znalazłem też takie informacje:
Czyli PB powoli, ale jednak reaguje z chlorem i się łuszczy. Dalej:What Causes Polybutylene Pipes to Leak?Evidence suggests that certain treatment compounds in municipal water (e.g. chlorine and chloramine) can cause polybutylene pipes to degrade and deteriorate from the inside out.
Eventually, this deterioration can result in cracks, leaks, and bursts.
How long do Polybutylene pipes usually last? Poly-B Life ExpectancyAlthough Polybutylene piping may last up to 30 years, many polybutylene plumbing systems fail in as early as ten years.
Due to the nature of water, we strongly urge homeowners with Polybutylene piping to replace their piping systems before they find out the hard way that their PB pipes are no longer suitable.Z pewnością do wody higienicznej użyję rur PEX z wkładką alu, PB biorę pod uwagę w kotłowni, do zasilenia rozdzielaczy i grzejników. Nie mniej, wolałbym nie mieć problemów z chemią, którą przecież użyję do zabezpieczenia instalacji CO.Any plumbing system can fail at any time. However, Polybutylene is considered a far higher risk than other materials like copper or PEX.
edit: Jeszcze to:
Polybutylene pipes have been debated for years due to their tendency to fail and cause property damage. The chemicals in public water systems, such as chlorine and fluoride, may contribute to polybutylene pipe failures.
