Does Your Home Have Polybutylene Pipes? Here's What You Need to Know

Polybutylene piping was widely used in BC homes built between 1978 and 1995. If your home has it, you need to read this.

If your home was built between 1978 and 1995, there's a good chance it has polybutylene (poly-B) pipes. This grey plastic piping was popular because it was cheap and easy to install — but it has a serious problem.

What is polybutylene? Poly-B is a type of plastic resin that was used extensively in residential plumbing throughout North America. It was eventually discontinued after widespread failures led to class-action lawsuits in the United States.

Why is it a problem? Poly-B pipes react with chlorine and other oxidants in municipal water supplies. Over time, this causes the pipes to become brittle and crack — often without any warning. The failures can happen inside walls, under floors, or in ceilings, causing significant water damage before you even notice.

How do I know if I have poly-B? Look for grey plastic pipes (though they can also be blue or black) with the markings 'PB2110' stamped on them. They're commonly found under sinks, in utility rooms, and in crawl spaces.

What should I do? The safest course of action is to have your poly-B pipes replaced before they fail. Modern materials like PEX and copper are far more durable and reliable.

Insurance implications. Many insurance companies in BC now refuse to insure homes with poly-B pipes, or charge significantly higher premiums. Replacing them can actually save you money on insurance.
