Class Eligibility

You are a member of this class action settlement if you own or owned buildings located in the United States that were built on or after Jan. 1, 2002, and which contain (or contained) Uponor yellow brass fittings.

Class Members of the Nevada Uponer pipe fitting settlement include anyone who owns or owned buildings with the Uponor yellow brass fittings in the Las Vegas Valley.

One way to identify if your building qualifies is to look inside the electrical panel and see if you have a a yellow sticker that say “Uponor,” “Wirsbo” or “Aquapex.” Alternatively, you may hire a plumber to identify your plumbing (though you will be responsible for payment of these costs). If you do hire a plumber, make sure you keep a copy of all documentation (such as color photos) to confirm the products are present.

Estimated Amount

Up to $60,000 Nationwide or up to $150,000 in Nevada

This money will be paid into a settlement fund that will be used to reimburse eligible Class Members for repairs or replacement costs relating to leaks or flow issues, and related property damage.

Proof of Purchase


Class Members must provide documentation that they have the Uponor piping installed in the building. They may submit physical evidence, such as the Uponor yellow brass fittings, or other documentation that the Uponor pipe fittings were installed in the building. Photographs, an inspection report or a notorized plumber’s report can be submitted as proof that the Uponor yellow brass fittings were installed in the property.

    How can I prove if I no longer own the property ?

    ADMIN – Hi Mike,

    You may be able to come to an agreement with the current owner in order to facilitate an inspection but this would only make sense if you incurred expenses that you can document related to leaks that can be directly attributable to the faulty product.

  2. Tanya says:

    I purchase my home from a builder in 2008 how can I tell if they used brass pipe fitting?

    ADMIN- Hi Tanya,

    Follow the instructions on the settlement to figure out if you have brass fittings. Alternatively, consider hiring a plumber.

  3. Carolyn says:

    It states for previous damage a claim must be filed six months after the class action settlement has been approved. When was the settlement approved?

  4. Mary says:

    They did not tell us that they were using brass pipes on our home and they busted and we had water all over the place

  5. JD says:

    My home in an affected zip code has a water leak under the foundation near the kitchen sink. There are no stickers in my electrical box. I am one of three homes known to have current subfloor leaks. Could this be a faulty Upnor fitting if the copper water line under the house was “rolled copper”?

    ADMIN – Hi JD,

    We have no idea. You will have to contact an expert.

  6. Carolyn says:

    I have called every other month to check up on the status of my claim. I completed all paperwork and submitted promptly in August 2015 with full detail of paperwork attached and signatures of my bills and notarized; yet I am told that you don’t have any clue about disbursement a or can give me any kind of update. This is sounding more like fraud .

    ADMIN – Hi Carolyn,

    Please remember that we are just an informational website and not the class action administrator. We don’t have access to your claim. Our website is purely educational.

  8. MANJU NATH says:

    ADMIN – Hi Manju,

    We are not plumbing specialists but my suggestion would be to replace them with a product that is not defective.

  9. Paula Hankins says:

    Brought this home in 2016, placed tenants in February of 2017, started having pipe problems, had a leak in the first restroom and plummer came out and fixed it shortly afterwards another leak started in the dinning room and the plummer fixed it. Kust last month another leak started in the laundry room so an leak detector came out, he explained to the plummer where the leak was so the Plummer cut out the walls and explained to me that I had those pipes they had a revall on those type of pipes so he suggested I do a rerouting of the pipes in the house, instead of fixing it because the same thing was going to happen in another section of the pipes, so that whst I did. Wanted to know woyld I be considered in this class action?

    ADMIN – Hi Paula,

    If there is a recall I would encourage you to contact a class action attorney.

    ADMIN – Hi Darlene,

    Having brass pipes does not necessarily make you a member of this class.

  11. Gayla says:

Many major plumbing issues and mold and more not disclosed. Getting sick. What can we do to get attorney that can look after our best interest and get paid from damages.

    ADMIN – Hi Gayla,

    The first step is to locate a class action attorney in your area.

  12. Dennys says:

    If uponor brass fitting are failing Wonder why still those fitting are been using by all Nation wide by Plumbers and inspected by City inspectors ?

    ADMIN – Hi Dennys,

    I wish we knew. I think part of the problem is that the fittings market does not have much in the way of competition.

  13. Suzanne Ramsey says:

    Our house was built in 2005. We purchased in 2010. and have had 3 leaks in the same piece of Wisbro Unopor tubing in the same piece (was spliced twice), then replaced. The pieces with the leaks were cut out, then thrown away by plumber, none of us knowing about the class action suit. I did have a four foot piece of the same, defective tubing )which the 3 pin hole leaks occurred but those specific pieces cut out), for which was sent to Uponor. Was told there was no defect or leak noted. Explained the leak portions were thrown out by the plumber. As a lay person (not plumber, one can see the opaque tubing had changed color and the lettering/numbers on the majority of the defective piece was blurred when compared with another piece of tubing which ran parallel with the defective piece which lettering was clear and color a slight bit whiter. I have many photos and videos documenting the leaks, but told since they didn’t have evidence, they wouldn’t pay on claim. Is this acceptable?? Something sounds strange to me.

    ADMIN – Hi Suzanne,

    You could always reach out to class counsel and ask.
