A Bismarck resident says a plumbing parts company has sold defective tubing systems that have led to water leaks in his house and others.

Brian Johnston, who owns a home in Bismarck, and Beverly Barnes, who lives in the same residence, have filed a federal lawsuit against Texas-based Zurn-Pex Inc., and Zurn Industries, Inc. The plaintiffs are asking to have the case declared a class-action lawsuit.

Officials from Zurn Industries could not be reached for comment.

The lawsuit claims the company's brass crimp fittings are poorly designed and manufactured and have failed only months after installation. The water leaks have caused extensive damage and have led to mold and other health problems, the complaint said.
