Polybutylene Piping: Is it Really That Bad?

What is Polybutylene Piping?

Polybutylene piping is made from polybutylene which was a commonly manufactured type of plastic between 1978 and 1995.  It was primarily used for piping home plumbing systems.  It was initially thought to be a great and inexpensive product that offered several distinct advantages over existing plumbing materials.  Polybutylene piping was a very popular choice for home builders.  Builders are believed to have installed it in as many as ten million homes in the United States.  Production of this product, however, was halted in 1996 after multiple allegations that the plastic material was failing at a very high rate and causing property damage.

Why and How Does it Fail?

There have been several studies performed on the failure of polybutylene piping.  Two of the most noteworthy were published by the University of Illinois at Chicago.  These polybutylene studies have discovered that certain disinfectants can react with the piping and cause it to flake apart.  These small fractures can deepen over time causing leaks.  While some manufacturers of the product claim that most leaks happen at the joints and unions due to improper installation, there have been multiple class action lawsuits against them that have resulted in substantial payouts to affected homeowners.  These payouts have to date reached over one billion dollars.

How Do I Know if I Have It?

While there are several other plastic piping types, like PEX, PVC, and polyethylene, there are a few indicators that make polybutylene piping stand out.  A stamped code, 'PB2110', is a clear indicator that it is polybutylene.  Additionally, it typically comes in grey, but can be found in black, blue, and silver.  Ultimately, however, if you cannot tell for certain that you have it, take a minute to give us a call.  We're happy to provide a free assessment to determine what type of piping your home has.

Uh Oh, I Have Polybutylene Piping: What Now?

Although there are no laws or any type of regulations that require a homeowner to replace polybutylene piping, it is usually the recommendation of any licensed plumber.  It's important to keep in mind that since this type of piping has such a high failure rate it is possible that a leak could develop and cause extensive damage to the home.  You may also encounter higher insurance premiums or even be denied coverage due to the enhanced risk.

In the event you consider selling your home, home inspectors are going to flag this type of piping to potential buyers.  It may make it difficult to sell and you may find yourself having to replace it at this time.

It is always our recommendation that you replace polybutylene piping systems before a disaster occurs.  It is less expensive to replace this piping than to deal with the damage caused by a major water leak.
