Lack Of Reliance Dooms Uponor Leaky Pipes Class Action
The judge, U.S. District Judge Edward M. Chen, dismissed the plaintiffs’ UCL, CLRA and fraud-by-concealment claims without leave to amend. The central problem was that the homeowners alleged they didn’t even know Uponor PEX piping was installed in their homes until after the pipes leaked. Therefore, they couldn’t plausibly show that they relied on something Uponor said—or failed to say—when they bought their homes. 
But there’s an important qualification –  The ruling doesn’t mean the court found the Uponor pipes weren’t defective.
