Kitec plumbing has been the subject of many lawsuits across North America, including a large cross-border class action which was concluded in 2011. A settlement fund of $125 million (all figures U.S.) was established, with $25 million going to the lawyers in Canada and the U.S., and $100 million being set aside for claimants who have until January, 2020 to file.
With an estimated 87,600 claims, the payout to each claimant will be nominal and the final amounts will not be settled until the expiry of the claims period in 2020.
If you have a property with Kitec piping, you should register in case you have a failure in the future. You have until 2020 to register. If you have a failure, document it and send the bill for repairs. You will get some relief, although you will not likely receive full reimbursement for the costs.
