Yes, polybutylene can be a concern when buying a home. Over time, polybutylene pipes can break down and become more prone to leaks, which can lead to severe water damage and costly repair. Since this type of plumbing system is now outdated, any repairs that need to be done to the pipes may be costly. It is best to have a professional home inspector check for any signs of polybutylene pipes before making an offer on a home.
Polybutylene piping, also known as Poly-B, is a type of plastic plumbing used in both hot and cold water systems in the home. It was commonly used from the 1970s to the mid-1990s and is now considered outdated. The main danger of Poly-B is that it is prone to cracking and leaks due to long-term exposure to chlorine and other chemicals found in tap water. In some cases, it can cause extensive water damage to walls and floors.
The matter of Poly-B has been a major concern since the early 2000s. In 2006, the U.S. Consumer Product Safety Commission issued a nationwide warning on the dangers of the piping, and soon after, a class action lawsuit was successfully filed against the manufacturer.
The recommended course of action for anyone with Poly-B plumbing is to replace it with a safer, more reliable material such as copper or PEX. It is also important to inspect the system regularly for signs of damage and to take any necessary steps to ensure that leaks do not occur.
