When was Poly B™ Banned?
There are 2 different dates on which polybutylene piping was banned.
The use of Poly B™ was banned by the National Plumbing Code, which oversaw all plumbing trades in Canada and refused to recognize Poly B™ after 1997. The pipe was disallowed to be used to construct any building requiring piping systems.
The government of Canada officially banned Poly B™™ in 2005. The ban’s reasoning was that a substantial volume of lawsuits were filed against Shell and Dupont over structural damage and property damage caused by ruptured Poly B™ piping throughout hundreds of homes. Poly B™ was reported to be failing after a few years of installation.
This resulted in structural damage to drywalls, water damage, and costly restoration. Shell and Dupont lost the lawsuit.
Poly B™ Lawsuits and Litigation History
Combined class-action lawsuits made Poly B™ one of the highest pre-settlement lawsuits in North American history. The total combined lawsuits amount to multiple billions of dollars.
Poly B™ Insurance Coverage
Poly B™ piping has proven to be a huge liability for both homeowners and insurance companies. In 2005, the Supreme Court of Canada deemed Poly B™ inadmissible to indemnity clauses. This means that no insurance company is required to ensure a home with Poly B™ piping under law.
Until recently, most insurance companies have offered grandfather clauses to current customers with Poly B™ piping and leniency to new clients. However, because of the losses incurred by insurance companies, most of them are no longer willing to renew policies or insure new clients that come to them with Poly B™ in the home. Legally, they do not have to because of the Supreme Court’s ruling in 2005.
Buyer beware, If an insurance company does offer to insure the home, there are typically massive premiums and costly deductibles following a first leak.
