Written by Anne Reagan. May 13, 2014. Polybutylene piping is a form of plastic resin and was commonly used for plumbing U.S. homes built between 1978 and 1995. Due to its inexpensive production cost and ability to withstand high water pressure, it was widely seen as a better, cheaper alternative to copper plumbing.
Knowing the types of plumbing pipes in your home lets you take steps to prevent leaks, flooding, and potential health hazards. Polybutylene is prone to breakage, but it can be replaced with PEX, as it was here. Nothing lasts forever, and that includes the plumbing pipes in your home. Fortunately, the majority of pipe materials perform well for decades. However, when that lifespan is reached, pipes may start to leak.
