Why does my Poly-B need to be replaced? 

Polybutylene resin is a type of plastic that was used to make the Poly-B piping- the popular piping choice in Calgary for homes built and renovated in the mid 1970s and late 1990s. 

During this time, Poly-B was seen as a cost effective and durable alternative to copper. By 1998, the production of Poly-B pipes halted as many homeowners began to see the pipes failing. The Canadian plumbing code removing Poly-B as a viable material altogether in 2005. 

Reasons why Poly-B pipes are bursting and leaking: 

• The chlorine in municipal waters degrade these types of pipes leading to embrittlement and cracking

• Higher water pressures stress pipes and fittings, accelerating the breakdown process

• Extreme temperatures contribute to the degradation of these pipes

• Plastic or aluminum crimp fittings were commonly used back then, and these are prone to cracking or loosening

Why it matters to you today

There are many Calgary homes that still have Poly-B pipes making up a significant part of their homes plumbing system. These pipes can decrease the resale value of your home and even affect your eligibility for home insurance! Many insurance companies now require Poly-B replacements before providing home coverage with its increased risk of water damage associated with this piping material. 

Put your knowledge to use!

Poly-B pipes can burst with little warning and can cause extensive damage. 

• Look at the pipes in the exposed areas of your home (usually in the utility room or basement). Poly-B pipes are grey or blue plastic pipes with plastic fittings instead of copper. The pipes also sometimes have markings like "PB". 

• Look around your house. Are there signs of water damage? Are there discoloured walls or musty odours? 

Whether you're thinking of buying, selling, or settling into your forever home, truly consider it's Poly-B status. Thinking ahead could save you in the long run!
