Poly B (polybutylene) is a gray plastic tubing that was a popular choice for water-supply plumbing pipes in homes between 1978 and 1995. Unfortunately, water pressure, UV and chlorine in municipal water supplies caused the plastic to break down and rupture.

Poly B was popular between 1978 and 1995, when it was discontinued after reports of pipes rupturing. Since then, copper or more dependable forms of plastic pipe (such as CPVC or PEX) are top choices.

Not all plastic pipes are Poly B.    

Poly B is a grey-ish flexible plastic. In some cases, it might be stamped with “poly B potable” or “PB2110” somewhere along the length of the pipe. Try checking the water supply lines under your sink or in your basement near the hot water tank to see if you can find the telltale stamp.    

Other (and more home-friendly) plastic pipes like black ABS or PVC pipes or PEX pipes that can be white, translucent, red or black are good news for you and your plumbing.

Since 2005, insurance companies haven’t been legally obligated to cover Poly B damages, so most don’t.    

In 2010, three class-action lawsuits were launched and have since been settled. Any compensation has been disbursed, so homeowners replacing their Poly B pipes may have to cover the costs themselves.  

It's hard to estimate exact prices, as the cost to replace your Poly B pipes depends on your home's size and the complexity of your plumbing systems. On average, you can expect to pay between $5,000 and $15,000 or more to re-pipe your home.
