The Quest for Justice: A Comprehensive Guide to the Qest Pipe Lawsuit

For many homeowners across the United States, the name “Qest” evokes a sense of dread and financial burden. Qest, a brand of polybutylene (PB) pipes, was widely used in residential plumbing systems from the late 1970s to the mid-1990s. Unfortunately, these pipes proved to be defective, leading to widespread leaks and property damage.

The Nature of the Defect

PB pipes are prone to a molecular breakdown that can cause them to crack and leak. This defect is exacerbated by exposure to chlorine, a common disinfectant used in municipal water supplies. Over time, the chlorine can weaken the PB molecules, leading to failures that can occur at any point in the plumbing system.

The Legal Battle

The first class-action lawsuit against Qest was filed in 1982. Over the years, numerous other lawsuits followed, alleging defective manufacturing and installation. In 2004, a landmark settlement was reached in the case of Cox v. Shell Oil, the parent company of Qest. The settlement provided $950 million in compensation to homeowners who had experienced leaks due to Qest pipes.

Impact on Homeowners

The Qest pipe lawsuit has had a significant impact on homeowners across the country. Many homeowners have faced the financial burden of replacing their Qest plumbing systems, which can cost tens of thousands of dollars. Additionally, the leaks caused by Qest pipes have led to water damage, mold growth, and other property damage.


The Qest pipe lawsuit serves as a cautionary tale about the importance of using quality materials in home construction. It also highlights the power of class-action lawsuits to hold corporations accountable for defective products.
