Commonly Asked Questions

Why was this notice issued?


The Court authorized the notice because you may be a potential Class Member and have a right to know about a proposed Settlement, and about your rights and options, before the Court decides whether to approve the Settlement.  You will be informed of the progress of this Settlement and may receive benefits if you are a Class Member and submit a completed and timely Claim Form.  The notice explains the lawsuit, the Settlement, and your legal rights.  

Judge Nancy D. Freudenthal is currently overseeing this case for the United States District Court for the District of Nevada.  The case is known as In re Wirsbo Non-F1807 Yellow Brass Litigation, No. 08-CV-1223.  The people who sued are called the “Plaintiffs.”  Uponor Inc., Wirsbo Company, and Uponor Wirsbo Inc., together called Uponor, and certain developers/builders, subcontractors, and suppliers/distributors (together called the “Other Defendants”) are the “Defendants.”  A complete list of the Other Defendants is available in the Long Form  Notice.

What is this lawsuit about?


The lawsuit claims that Uponor Yellow Brass Fittings and components made from high zinc content brass were defectively designed and prematurely corrode (or break down) when drinking water supplied by the Southern Nevada Water Authority runs through them.  This chemical process is called “dezincification.”  The lawsuit also claims that when the high zinc content brass is exposed to this water over time, it becomes blocked, cracks, weeps, seeps, and/or leaks and may affect your water supply.  There are no known water quality issues concerning the drinkability of the water supplied by the Southern Nevada Water Authority.  

Uponor and the Other Defendants deny all of the claims and allegations made in the lawsuit.  Uponor believes they acted responsibly in the design of plumbing products and components that are made from high zinc content brass.  The Other Defendants believe they acted responsibly in supplying, selecting, using, and installing the plumbing products and components in plumbing systems.

High zinc content brass is material that is made primarily of copper and 30% (or more) zinc.  The high zinc content brass products in this case, Uponor Yellow Brass Fittings, were made of UNS C36000, C37700, or C35330 brass or similar copper alloys and were used as components of a piping plumbing system (called the “Uponor/Wirsbo PEX System”).  This lawsuit is not about personal injuries, wrongful death, or emotional distress. 

Why is this a class action?


In a class action, one or more people called “class representatives” (in this case, Michael Mahany and Raina Musser-Mahany, Wendy Stockett, Christian and Bobbi LeCates, Michael and Tricia Crowder, Christian and Laurie Jensen, Leon Turner, and Fulton Park Unit Owners’ Association) sue on behalf of people who have similar claims.  All of these people are a “class” or “class members.”  One court resolves the issues for all class members, except for those who exclude themselves from the class.

Why is there a Settlement?


The Court has not decided in favor of the Plaintiffs, Uponor, or the Other Defendants.  Instead, both sides have agreed to a Settlement.  By agreeing to the Settlement, they avoid the costs and uncertainty of a trial, and Class Members will receive the benefits described in this notice.  The proposed Settlement does not mean that any law was broken or that Uponor or the Other Defendants did anything wrong.  The Class Representatives and the attorneys think the Settlement is best for all Class Members.

How do I know if my home has these products?


There are several ways to find out if your home has these products.

  • List of Affected Neighborhoods: Click here to find a partial list of known neighborhoods where the products were used.
  • Identifying Stickers: Look inside your electrical panel for a yellow sticker that says “Uponor,” “Wirsbo,” or “Aquapex.”  Not all homes containing these products have a sticker on the electrical panel box.  Click here to see photos of what these stickers look like.
  • Confirmation by a Plumber: You may also hire a plumbing company that knows how to identify these products.  If you choose to hire a plumber, you will be responsible for paying them. Be sure to keep a copy of the plumber’s documentation, including color photos or other files that confirm the products are present.

I am still not sure if I am included.


If you are not sure whether you are included or have any other questions about the Settlement, you can get free help. Visit the website,, or call the toll free number, 1-888-227-9828.  Or you can fill out and return the Claim Form, to see if you qualify.  You may also send questions to the Settlement Administrator at Nevada Uponor Settlement, PO Box 2276, Faribault, MN 55021-2397.

What does the Settlement provide?


If the Settlement is approved and becomes final, it will provide benefits to Class Members.  Uponor and the Other Defendants will pay money into a Settlement Fund to reimburse Class Members for eligible previous repairs and/or future repairs or replacement costs relating to leaks or flow issues along with related property damage.  Uponor will also provide an extended warranty for eligible property damage and water flow issues. 

Uponor will commit $7 million to initially fund the Settlement and will add money to the fund to ensure it does not go below $4 million as claims are being paid.  After five years, the Settlement Fund will be reduced to $4 million, and after eight years, any money above $4 million will go back to Uponor.

Uponor will also pay for the costs associated with the notice and administration of the Settlement, attorneys’ fees and costs, and special service payments to the Class Representatives.  The Other Defendants are contributing $18 million in funding for the Settlement.

The Settlement Agreement, available under the Court Documents tab, has more information.

What can I get from the Settlement?


The amount of any benefit you may receive will depend on the amount and type of included property that you own and the damage you have experienced and/or repairs or replacement needed.  The benefits chart in the Long Form Notice summarizes the included types of claims and maximum payment amounts or benefits available based on the kind of property owned.

What is the Extended Warranty?


Uponor will provide an Extended Warranty for eligible Property Damage Claims and Low Flow and Fitting Replacement Claims that result from dezincification of Uponor Yellow Brass Fittings as follows:

  • Warranties Regarding Property Damage: All Class Members will have a 15-year warranty for eligible Property Damage Claims relating to Uponor Yellow Brass Fittings from the date of installation of their Uponor/Wirsbo PEX System.  The minimum warranty period will be two years from Final Settlement Approval (including Class Members whose warranties have expired).
  • Warranties Regarding Low Flow and Replacement Failures: All Class Members will have a 25-year warranty for eligible Low Flow and Fitting Failure Replacement Claims relating to Uponor Yellow Brass Fittings from the date of installation of their Uponor/Wirsbo PEX System.  This will run concurrent with any other applicable warranty(ies).

How can I get benefits?


To get benefits from the Settlement, you must send in a Claim Form.  You can get a Claim Form under the Claim Form tab of this website.  Please read the instructions carefully, fill out the form completely and accurately, sign the form, and include all the documents the form asks for.  Your Claim Form must be submitted by the deadlines provided in the Settlement Agreement (generally within 12 months of the loss/event) and addressed to:  

Nevada Uponor Settlement
PO Box 2276
Faribault, MN 55021-2397

When will I get benefits?


The Court will hold a hearing on October 22, 2015 to decide whether to approve the Settlement.  Payment of claims will begin only after the Court grants final approval to the Settlement and any appeals are resolved.  If there are appeals, resolving them can take time.  Everyone who sends in a Claim Form will be informed of the progress of the Settlement.  Please be patient.

How long is the claims period?


The claims period will run for eight years from when the Settlement is approved.  After that, claims should be submitted to Uponor for the duration of the extended warranty.

What am I giving up to get a payment or stay in the Class?


If the Settlement becomes final, unless you exclude yourself, you will give up your right to sue Uponor and/orthe Other Defendants for the claims being resolved by this Settlement.  You will be bound by all the Court’s orders.  You will be “releasing” Uponor, the Other Defendants, and all related people as described in Section 83 of the Settlement Agreement.

The Settlement Agreement describes the claims that you give up if you remain in the Settlement.

What if I don’t want to be included in the Settlement?


If you do not want to receive benefits from this Settlement, but you want to keep the right to sue Uponor and/or the Other Defendants on your own about the issues in this lawsuit, you must exclude yourself (or “opt out”) of it.  If you exclude yourself, you will not be bound by any Court orders in this case.

The attorneys’ motion for fees, costs, and expenses and Class Representative payments will be filed on or before October 9, 2015.  The motions will be posted on this website.  Uponor and the Other Defendants have agreed not to oppose these motions for fees and expenses.  Uponor will also separately pay the costs to administer the Settlement. 

Should I hire my own lawyer?


Class Counsel is representing you and all of the other members of the Class.  If you want to be represented by another lawyer, you may hire one to appear in Court for you at your own expense.

How do I tell the Court that I don’t like the Settlement?


If you choose to remain a Class Member, you can object to the Settlement if you don’t like any part of it.  You can give reasons why you think the Court should not approve it.  The Court will consider your views.

To object, you must send a letter stating that you object to In re Wirsbo Non-F1807 Yellow Brass Litigation, No. 08-CV-1223.  Your written objection must also include:

  • Your name;
  • Your current address and telephone number;
  • The address of the property(ies) that may contain Uponor Yellow Brass Fittings; 
  • A written statement of your objection(s), including any legal support and/or any supporting evidence you wish to introduce; 
  • A statement of whether you intend to appear and speak at the Fairness Hearing; 
  • Your signature; and
  • Your attorney’s signature (if you are represented by one). 

If you choose to object, in order to be considered by the Court, your written objection must be mailed to each of the following addresses and received no later than August 19, 2015:

If you received a postcard marked as “Supplemental Notice” in the mail, you have until October 2, 2015 to object to this Settlement.

What is the difference between objecting and asking to be excluded?


Objecting is simply telling the Court that you don’t like something about the Settlement.  You can object only if you stay in the Class.  Excluding yourself is telling the Court that you don’t want to be a part of the Class.  If you exclude yourself, you have no basis to object to the Settlement because the Settlement no longer affects you.

When and where will the Court decide whether to approve the Settlement?


The Court will hold a Fairness Hearing at 9:00 a.m. PST on October 22, 2015, in Courtroom 4B before Judge Nancy D. Freudenthal in the United States District Court for the District of Nevada, located at the Lloyd D. George Federal Courthouse, 333 South Las Vegas Boulevard, Las Vegas, NV 89101.  The hearing may be moved to a different date or time without additional notice, so it is a good idea to check this website for updates.

At this hearing, the Court will consider whether the Settlement is fair, reasonable, and adequate.  If there are objections, the Court will consider them.  The Court will listen to people who have asked to speak at the hearing.  The Court may also decide whether to award attorneys’ fees and costs, as well as the special payments to the Class Representatives.  After the hearing, the Court will decide whether to approve the Settlement.  We do not know how long these decisions will take.

Do I have to come to the hearing?


No.  Class Counsel will answer questions the Court may have at the Fairness Hearing.  But you are welcome to come at your own expense.  If you send an objection, you don’t have to come to Court to talk about it.  As long as you mailed your written objection on time, the Court will consider it.  You may also pay your own lawyer to attend, but it’s not necessary.

May I speak at the hearing?


Yes, you may ask the Court for permission to speak at the Fairness Hearing.  To do so, you must send a letter stating that it is your “Notice of Intention to Appear in In re Wirsbo Non-F1807 Yellow Brass Litigation, No. 08-CV-1223.”  Your Notice of Appearance must also include:

  • Your name;
  • Your current address and phone number;
  • The details of what you want to be heard about; and
  • Your signature. 

Your Notice of Intention to Appear must be received no later than August 19, 2015 to the addresses listed in the "How do I tell the Court I don't like the Settlement?" FAQ.  You cannot speak at the Fairness Hearing if you excluded yourself.  

What happens if I do nothing?


If you do nothing now, you will remain in the Class and get no benefits at this time.  However, you will be eligible to receive the Settlement benefits if you submit a valid claim in the future.  You will be bound by all the Court’s orders, and you will not be able to start, join, or continue to sue Uponor and/or the Other Defendants about the same legal claims resolved in this Settlement.
