You will have 12 years from construction to file a claim for the interior piping, and 10 years for the exterior pipe from the meter. I advise my customers to file a claim as soon as they know they have PB tubing.: Why is poly-b tubing taken off the shelf? : What was the reason for changing the product? : My house is 8 years old, and all of the plumbing is poly B tubing, do I have to worry in regards of any problems? : Im looking forward to your reply! : Thank you very much, : Adam
