Polybutylene Water Piping

Polybutylene piping, often abbreviated as PB, was once hailed as an innovative solution for residential plumbing systems. Emerging in the late 1970s and gaining popularity throughout the 1980s and 1990s, polybutylene promised an affordable and easy-to-install alternative to traditional plumbing materials like copper. This type of piping has since garnered a controversial reputation due to a series of significant issues.

Things to know if you have Polybutylene pipes:

Commonly Sold polybutylene (PB) pipe

Polybutylene pipes were sold under several brand names during their heyday. The most common brand names associated with polybutylene piping include:

– Quest
– Vanguard
– PB 2110
– Thermoguard
– Flarex
– Qest
– PlumbBetter
– PolyPipe

These various brand names were used by different manufacturers, and the pipes themselves were essentially made of the same polybutylene material. While these pipes were once widely used, as mentioned earlier, concerns about their reliability and durability have led to a decrease in their usage, and they are no longer recommended for new installations in many places.

When did they stop using polybutylene (PB)?

The use of polybutylene (PB) pipes in residential plumbing significantly declined in the mid-1990s and was mostly discontinued by the late 1990s. This decrease in usage was due to widespread concerns about the pipes’ long-term reliability and durability. Instances of leaks and failures, particularly in regions with certain water chemistries, led to numerous lawsuits and class-action settlements.

As a result of these concerns and legal actions, many plumbing codes and standards were updated to discourage or prohibit the use of polybutylene pipes in new construction. Additionally, the plumbing industry shifted towards other materials such as copper and PEX (cross-linked polyethylene) for water supply lines.

While some homes built during the 1980s and early 1990s may still have polybutylene plumbing systems, it is generally no longer installed in modern construction. Homeowners with polybutylene pipes often choose to replace them with more reliable and durable materials to prevent potential water damage issues.

What is the lifespan of polybutylene (PB)?

The Life Span of PB pipe The average lifespan of polybutylene (PB) pipes can vary widely depending on several factors, including the quality of the installation, the specific brand and type of PB pipe used, the local water chemistry, and other environmental factors. However, it is generally accepted that PB pipes have a lifespan of about 10 to 25 years on average.

Keep in mind that this estimate is quite short compared to other plumbing materials like copper or PEX (cross-linked polyethylene), which can last significantly longer if properly installed.

The relatively short lifespan of PB pipes is due to concerns about their durability and potential for deterioration over time, especially when exposed to certain water conditions. PB pipes are known to be susceptible to damage from chlorine and other oxidants in the water supply, which can cause the pipes to become brittle, weaken, and develop cracks or leaks.

Is polybutylene piping illegal?

Polybutylene piping is not illegal, but its use in residential plumbing has been largely discontinued and discouraged in many regions due to concerns about its long-term reliability and potential for leaks. This type of plastic piping was commonly used in residential plumbing systems from the late 1970s through the mid-1990s.

The reason for its decline in popularity is the significant number of reported issues with polybutylene pipes, including a tendency to become brittle and deteriorate over time, which can lead to leaks and plumbing failures. These problems resulted in numerous lawsuits and a loss of confidence in the material’s long-term performance. As a result, many building codes and insurance companies now discourage or even refuse coverage for homes with polybutylene plumbing.

While it may not be illegal, it’s essential to check with local building codes and regulations in your area to determine the specific rules and guidelines regarding the use of polybutylene piping in plumbing systems. However, if you’re considering purchasing a home with polybutylene plumbing or have it in your current home, it’s advisable to consult with a plumbing professional to assess its condition and consider replacement with more modern and reliable piping materials if necessary.

Polybutylene piping lawsuit:

The major lawsuit related to polybutylene piping was a class-action lawsuit known as Cox v. Shell Oil. This lawsuit was filed in the United States in the 1990s. The case revolved around the use of polybutylene pipes and the associated fittings and components manufactured and marketed by several companies, including Shell Oil, which was involved in the production of the polybutylene resin.

The lawsuit alleged that polybutylene pipes and fittings were defective and prone to premature failure, resulting in water damage and costly repairs for homeowners. As a result of this lawsuit and similar legal actions, a settlement was reached, and various manufacturers established compensation funds to cover the costs of repairing damages caused by polybutylene plumbing systems.

It’s important to note that while this specific lawsuit gained significant attention, there were numerous other legal actions and settlements related to polybutylene piping throughout the years. These legal challenges contributed to the decline in the use of polybutylene pipes in residential plumbing and led to many homeowners replacing their polybutylene systems with more reliable materials.

What to do if you have Polybutylene piping:

If you have polybutylene (PB) piping in your home, it’s essential to address the potential issues associated with this type of plumbing material. While not all PB pipes experience problems, there are known reliability and durability concerns that have led many homeowners to consider replacements or take certain precautionary measures. Here’s what you should consider doing if you have PB piping in your home:

Assessment by a Professional Plumber: Start by having a professional plumber inspect your PB plumbing system. They can assess the condition of the pipes and look for signs of deterioration, leaks, or potential issues.

Consider Replacement: Given the known issues with PB pipes and their relatively short average lifespan (about 10 to 25 years), many homeowners choose to replace them with more durable materials like copper or PEX (cross-linked polyethylene). Replacing PB pipes can help prevent potential water damage issues and provide peace of mind regarding the integrity of your plumbing system.

Repair Leaks Promptly: If you notice any leaks or signs of water damage, it’s crucial to address these issues promptly. Even if you plan to replace the entire system eventually, immediate repairs can mitigate damage and prevent further issues.

Check for Manufacturer Assistance Programs: Some manufacturers and builders involved in the production and installation of PB pipes have established assistance programs to help homeowners with replacement costs. Check to see if you qualify for any such programs.

Understand Insurance Implications: Be aware that some insurance companies may have specific policies regarding homes with PB plumbing systems. Some insurers may refuse coverage, charge higher premiums, or require documented updates or replacements.

Disclose in Real Estate Transactions: If you plan to sell your home, you may be legally obligated to disclose the presence of PB pipes in real estate transactions, depending on local laws and regulations.

Consider Water Quality Testing: If you’re concerned about potential water quality issues related to PB pipes, consider having your water tested for safety and contamination. PB pipes can deteriorate and, in some cases, affect water quality.

Regular Maintenance and Inspection: If you decide to keep your PB plumbing temporarily, schedule regular maintenance and inspections to catch and address issues early.

It’s important to consult with a licensed and experienced plumber when dealing with PB pipes in your home. They can provide guidance on the best course of action based on the condition of your plumbing system and local regulations. Replacing PB pipes with more reliable materials is often recommended to avoid potential water damage and ensure the long-term integrity of your plumbing system.
