No class action has ever been certified against FlowGuard Gold CPVC plumbing. The main FlowGuard Gold CPVC lawsuit, Jones v. Lubrizol Advanced Materials, was filed as a putative class action in federal court in Ohio in 2020, but the court struck the class allegations in February 2022, leaving only the named plaintiffs’ individual claims.1Justia. Jones v. Lubrizol Advanced Materials, Inc. A separate Colorado case brought by a property owner ended in 2023 after Lubrizol won summary judgment.2GovInfo. Connell Solera LLC v. Lubrizol Advanced Materials, Inc. If you have failed FlowGuard Gold pipes, your route right now is an individual claim, not membership in a class.
What Homeowners Say Is Failing
The core allegation across these cases is that FlowGuard Gold pipes and fittings become brittle and fail well before the end of their expected service life, cracking or shattering and causing flooding, ceiling collapses, drywall damage, and mold.3vLex. Jones v. Lubrizol Advanced Materials, Inc., 559 F.Supp.3d 569 Plaintiffs have described pipes that were physically brittle and difficult to cut. The plaintiffs argued these are design and manufacturing defects.4Replumbs. CPVC Piping
Independent polymer analysts describe a related phenomenon called environmental stress cracking, in which contact with certain everyday construction materials causes CPVC to degrade over time. Failures of this kind typically appear three to seven years after installation and tend to be systemic within a building: one leak often signals broader vulnerability throughout the same plumbing system. Substances commonly implicated include fire caulks and sealants containing migrating plasticizers, jacket insulation on CAT5/6 communication cabling, pest control products and fungicides, and glycol-based antifreeze and certain cutting oils.5The Madison Group.

Why this matters legally: whether the failures come from a defect in the pipe or from contact with something incompatible after installation is exactly the question the two sides are fighting over.
Jones v. Lubrizol and Why the Class Failed
Kevin and Janet Jones of Arizona, Douglas Cochrane of Massachusetts, Donna Baker of Washington, and Catherine Martin of Michigan filed Jones v. Lubrizol Advanced Materials, Inc. on May 22, 2020, in the U.S. District Court for the Northern District of Ohio, case number 1:20-cv-00511.6Cuneo Law Group. CPVC Plumbing Systems1Justia. Jones v. Lubrizol Advanced Materials, Inc. The defendants were Lubrizol Corporation and Lubrizol Advanced Materials, which develop and market FlowGuard Gold and supply the raw CPVC compound, along with two manufacturers that extrude the pipe and fittings, Charlotte Pipe and Foundry Company and Cresline Plastic Pipe Company.3vLex. Jones v. Lubrizol Advanced Materials, Inc., 559 F.Supp.3d 569
The plaintiffs sought to represent a nationwide class and four state subclasses covering anyone who had owned a structure with FlowGuard Gold installed since 1991. Their surviving claims after a September 2021 motion-to-dismiss ruling were breach of express warranty under each plaintiff’s home state law, and for the Massachusetts plaintiff, negligence and failure to warn.7Midpage. Jones v. Lubrizol Advanced Materials, Inc., 583 F.Supp.3d 10451Justia. Jones v. Lubrizol Advanced Materials, Inc.
On February 1, 2022, Judge J. Philip Calabrese struck all class allegations. The problem was standing. The proposed class swept in every homeowner with FlowGuard Gold installed since 1991, which meant it necessarily included many people whose pipes had never leaked. Uninjured class members lack the concrete injury Article III requires, and the court concluded that “no amount of discovery can cure that legal defect.”1Justia. Jones v. Lubrizol Advanced Materials, Inc. The court also rejected treating the case as an injunctive-relief class under Rule 23(b)(2), finding individualized monetary claims predominated.7Midpage. Jones v. Lubrizol Advanced Materials, Inc., 583 F.Supp.3d 1045
Plaintiffs were ordered to amend within 21 days to drop the class allegations, and the ruling was certified for interlocutory appeal.7Midpage. Jones v. Lubrizol Advanced Materials, Inc., 583 F.Supp.3d 1045 The individual claims continued, but there is no longer any class for other homeowners to join. Publicly available records do not show the outcome of an interlocutory appeal or a final resolution of the individual claims.
The Colorado Case: Connell Solera
A commercial property owner sued Lubrizol and Charlotte Pipe over failed FlowGuard Gold plumbing in Connell Solera, LLC v. Lubrizol Advanced Materials, Inc., case number 1:21-cv-00336, in the U.S. District Court for the District of Colorado. The claims included negligence, strict liability for design and manufacturing defects, failure to warn, breach of express warranty, and violation of the Colorado Consumer Protection Act.2GovInfo. Connell Solera LLC v. Lubrizol Advanced Materials, Inc.
On February 23, 2023, Judge Nina Y. Wang granted Lubrizol summary judgment and dismissed it from the case entirely. Charlotte Pipe’s motion was granted in part and denied in part, leaving some claims against it alive for potential trial. The court also sanctioned the plaintiff for spoliation because it had replaced the plumbing before Charlotte Pipe could inspect it. The plaintiff was barred from presenting expert testimony that the original fittings were installed properly, and Charlotte Pipe was permitted to tell the jury the system had been replaced before inspection. The court declined a stronger adverse inference instruction, finding no clear evidence of bad faith.2GovInfo. Connell Solera LLC v. Lubrizol Advanced Materials, Inc.
The docket shows the case terminated on April 3, 2023, roughly six weeks after that ruling. The record does not specify whether it ended in settlement, voluntary dismissal, or something else.8CourtListener. Connell Solera LLC v. Lubrizol Advanced Materials, Inc.
What Lubrizol and Charlotte Pipe Say Caused the Failures
Lubrizol maintains that FlowGuard Gold CPVC is reliable and that reported failures stem from how the product is handled after it leaves the factory. Its published materials identify five common causes: failure to accommodate thermal expansion, use of incompatible ancillary materials, improper repair techniques, incorrect application of solvent cement, and use of untrained installers.9FlowGuard. 5 Problems That Can Lead to CPVC Pipes Failing10FlowGuard Gold. Top 5 DIY Mistakes for Service Plumbers to Watch for With CPVC The company says FlowGuard Gold has been used in the U.S. for over 60 years with more than 11 billion feet of pipe installed and has never been the subject of a certified class action.11FlowGuard Gold. What Class Action Lawsuits Say About Residential Plumbing Material Quality
That defense appeared directly in the Jones warranty denials. When Charlotte Pipe rejected Douglas Cochrane’s claim, it attributed the failure to “environmental stress cracking caused by exposure on the exterior to incompatible plasticizers and nonionic surfactants” rather than a manufacturing defect.12CaseMine. Jones v. Lubrizol Advanced Materials, Inc. Whether that explanation holds up across the volume of reported failures is the central factual fight in this litigation, and no court verdict or regulatory finding in the public record has resolved it.
Warranty Claims and the Traps in the Fine Print
Filing a warranty claim is the practical first step for most homeowners, and the Jones plaintiffs’ experiences illustrate how those claims tend to be denied. Cochrane’s was rejected on the environmental-stress-cracking theory above. Donna Baker’s claim was denied on a different ground entirely: Charlotte Pipe said her home’s pipe had actually been manufactured by Thompson Plastics, not Charlotte Pipe. Catherine Martin, the Michigan plaintiff, submitted her claim to Cresline after multiple failures in 2019 and 2020 in a 1997-built home.12CaseMine. Jones v. Lubrizol Advanced Materials, Inc.3vLex. Jones v. Lubrizol Advanced Materials, Inc., 559 F.Supp.3d 569
Charlotte Pipe’s warranty terms have changed over time. Its 1999 limited warranty covered defects in material and workmanship for as long as the original owner lived in the home; a March 2008 revision cut that to ten years. Both versions require written notice within 30 days of discovering the defect, exclude consequential damages, and require the allegedly defective product to be made available for inspection.12CaseMine. Jones v. Lubrizol Advanced Materials, Inc.
Two practical points follow. The 30-day notice window is short, and the inspection requirement means replacing the failed section before the manufacturer sees it can sink both a warranty claim and a lawsuit. The Colorado spoliation sanctions came from exactly that mistake.2GovInfo. Connell Solera LLC v. Lubrizol Advanced Materials, Inc.
Where This Leaves You
There is no FlowGuard Gold class action to join. The Jones case continues on the four named plaintiffs’ individual claims, with no publicly recorded final disposition. The Colorado Connell Solera case is closed. Anyone with failed FlowGuard Gold plumbing is looking at an individual warranty claim or an individual lawsuit, and both depend heavily on preserving the failed pipe and fittings for inspection, documenting the failure quickly, and identifying which manufacturer actually produced the specific pipe in the home.
