Polybutylene pipes can be identified by their gray color and flexible, plastic-like material. They were commonly used in plumbing systems in the 1970s to 1990s. If you suspect you have polybutylene pipes, you can hire a professional plumber to inspect your plumbing system for confirmation.
Its not bad as long as they are not leaking. Unfortunately polybutylene pipes have the best chance to start leaking at some point and it can be costly to repair.
Polybutylene pipe is a discontinued pipe.
When looking to renovate a home, it may be natural to look for ways to cut back on costs. For example, when installing a new plumbing system, many may want to save money by installing polybutylene pipes. However, this form of piping should be avoided. The affordable polybutylene pipes have undergone an extreme amount of scrutiny over the past 30 years, and they not violate almost every building code in the United States, Europe, and Canada. The pipes were the center of many different class-action lawsuits as the plaintiffs have shown that the pipes can be deteriorated by small traces of chlorine.
The most effective methods for repairing polybutylene pipes include using push-fit fittings, crimp fittings, or PEX pipe replacement. It is important to consult with a professional plumber to determine the best solution for your specific situation.
As I understand it polybutylene hasn't been removed from the formal plumbing code, however the sale of polybutylene was quickly phased out in or around 1995 which is when the major class action lawsuit (Cox v Shell Oil) was settled for just shy of a billion dollars. As you likely know there have been countless problems with all variations of polybutylene pipes and associated fittings, and although it's still listed in the code, consumers should not consider this an endorsement of quality or performance.
Polyethylene and polybutylene are two common types of flexible tubing used in plumbing, and both are used in hot and cold water supplies in place of traditional copper lines.
KLPB pipes refer to a type of piping made from K-Lite Polybutylene, which is known for its flexibility, resistance to corrosion, and ease of installation. These pipes are often used in plumbing and heating systems due to their durability and ability to withstand varying temperatures. KLPB pipes provide an alternative to traditional materials like copper or PVC, making them a popular choice in modern construction.
Polybutylene is typically made through polymerization of butene or butadiene monomers. These monomers are chemically bonded together in a repeating pattern to form a long chain polymer called polybutylene. The process usually involves high pressures and temperatures, along with catalysts to control the reaction.
The price of a polybutylene pipe will depend on how big it is, if it has any alloys in it, and how long it is. Without this information, it is near impossible to give a quote on price.
