Poly-B

Polybutylene (Poly-B) is a type of plastic piping that was commonly used in residential plumbing systems from the late 1970s to the mid-1990s. It was initially considered a cost-effective alternative to traditional copper piping. However, over time, Poly-B has been associated with several issues that can affect homeowners. 

Poly-B piping is prone to deterioration and can become brittle and prone to cracking or rupturing, especially when exposed to certain chemicals or high water pressure. This can lead to leaks, water damage, and potential mould growth. Additionally, Poly-B pipes are susceptible to degradation from chlorine and other disinfectants commonly found in municipal water supplies. 

As a homeowner, it's important to be aware of the presence of Poly-B in your plumbing system and its potential risks. If your home has Poly-B piping, it may be prudent to consider having it inspected by a professional plumber. A plumber can assess the condition of the pipes, identify any signs of deterioration or potential issues, and provide recommendations for repairs or replacement if necessary.
