Is Your PEX Plumbing Failing? What Metro Atlanta Homeowners Need to Know
This page covers two specific PEX failure patterns that show up in Metro Atlanta homes. If you have recurring leaks, unexplained water damage, or a PEX system installed between roughly 2000 and 2020, you’re in the right place.
If you’re researching PEX as a replacement material for a repipe and your current pipes aren’t failing, see our PEX-A vs. CPVC materials guide. That page covers what Plumbing Express installs and why. This page is for a different situation.
The Subdivision Cluster Pattern
PEX failures in Metro Atlanta don’t happen randomly. One of the most consistent observations from our crews is that failures cluster geographically. Homes in the same subdivision, built in the same construction period, by the same developer, with the same pipe brand, tend to begin failing within a similar timeframe.
The reasons are straightforward. The same installer used the same materials from the same manufacturer. The homes have been exposed to the same water supply under the same conditions for the same number of years. When one home in a 2008 subdivision starts developing PEX-B fitting failures, the pipe in neighboring homes of the same era is under the same stress.
If a neighbor in your subdivision has had unexplained leaks or a repipe, that is a data point worth taking seriously, not a coincidence. It’s not always a signal that your system is about to fail, but it’s a reasonable reason to have an estimator assess your system before the next failure rather than after it.
Metro Atlanta clusters where Plumbing Express sees failing PEX most frequently:
Homes built from approximately 1995 through the mid-2000s in Cherokee County (Woodstock, Canton, Holly Springs), Forsyth County (Cumming), Henry County (McDonough, Stockbridge, Locust Grove), and the north Gwinnett corridor (Suwanee, Sugar Hill, Buford, Dacula) represent the primary concentration. South Metro markets including Newnan and Peachtree City have aging PEX housing stock as well.
If your home falls in one of these areas and was built during the 2000-2015 window, it’s worth confirming your pipe type and brand before leaks start rather than after.

Two Distinct PEX Failure Patterns
Not all PEX fails the same way. The two patterns Plumbing Express sees most often in Metro Atlanta are different in cause, different in how they were handled legally, and different in how they present in a home.
PEX-B Crimp Systems: NIBCO, Zurn, and Viega/Vanguard
The most widespread residential PEX failure history involves PEX-B pipe installed with crimp or clamp fittings, primarily between 2000 and 2020. The brands named in settled class action litigation include NIBCO, Zurn, and Viega/Vanguard.
How these systems fail. PEX-B failures tend to follow one of two paths. The first is fitting failure: the brass crimp fittings corrode, crack, or separate over time, producing leaks at connection points. The second is antioxidant depletion in the pipe itself. PEX pipe is manufactured with a reserve of chemical stabilizers that protect the polyethylene from oxidative breakdown. Contact with chlorinated water gradually depletes those stabilizers. Once they’re exhausted in a given section of wall, the pipe material begins to degrade internally, developing micro-cracks that eventually produce leaks. The fitting and pipe mechanisms can occur independently or together.
The litigation record. NIBCO, Zurn, and Viega/Vanguard have each been the subject of settled class action litigation over PEX system failures, a matter of public record.
How to identify a PEX-B crimp system. Look near the water heater and under bathroom sinks for the brand stamp on the pipe. NIBCO pipe is typically stamped “NIBCO” along the length. Look at the fittings: crimp and clamp systems use a visible metal ring compressed around the outside of the pipe. If you see copper or stainless rings crimped onto the pipe at connection points, that’s a PEX-B system.
Older Colored PEX: Red, White, and Blue Formulations
Some homes built or repiped after 2010 contain visibly colored PEX pipe: red for hot lines, blue for cold lines, white as a neutral. These older dyed formulations are distinct from current PEX-A products. If your home has colored PEX pipe and you’ve seen unexplained moisture, staining, or pressure changes, an in-home assessment is worth doing.
Plumbing Express installs Uponor ProPEX, which is undyed and uses a current formulation. If a repipe company is quoting colored PEX pipe, that is worth asking about. The pipe will be stamped along its length; look for the brand and product name near the water heater or under a bathroom sink.
What Plumbing Express Installs Instead
When a failing PEX system is replaced, Plumbing Express installs Uponor ProPEX or FlowGuard Gold CPVC. Both are turn-key installations: our crew handles the pipe work, the drywall repair at every access point, ceiling texture restoration, and paint blending. One team, one fixed-price quote, water restored to your home each evening during the project.
For a full comparison of the two replacement materials and how to choose between them, see our PEX-A vs. CPVC materials guide.

Service couldn’t be completed due to needing a new system. We appreciate the very informative visit as well as insight that could help after a new unit install.
Plumbing Express was great. I had a failed sump pump that had partially overflowed into the basement. Nasty. Josh was the tech that did the work. He was efficient, neat and courteous. I will use Plumbing Express if I have any other plumbing needs and I will recommend them to my family and friends.
The technician was very knowledgeable and professional. I believe they did a very good job.
Ron was our second plumber from this company. The first plumber came, examined pipes and said he found no leak, even though we had experiences a large amount of water leaking from the ceiling in the finished basement. Several days later we had another leak-same area but less water the second time. Ron came in, listened to our frustration and did a more thorough inspection of the pipes and identified the problem. He was very personable and professional. On his third visit, we had several replacement pipes installed and are without leaks again. Our frustration, with the situation, was my son had used your company to replace pipes when he purchased the home and founding out not all the pipes were included with that process.
Tim arrived on time and was very professional. He took his time to explain the problem and the process it would take fix the water line.
Called Plumbing Express as tankless hot water not operating. Their website states "Get Free Plumbing Quote ". When service man showed up an looked at unit he said there would be a $207 charge to look into unit in order to give me a quote to fix unit. Due to not having hot water and time required to get another company to address the problem I agreed to pay $207 for quote. After looking in unit I was told he would not be able to fix due to age of unit and parts not available. I think he should have said parts not available when seeing model number on front of unit and I would not have wasted $207.
Outstanding customer service, we will definitely be using them in the future for any plumbing needs. Can’t thank them enough!
Extremely knowledgeable and very helpful. The team was excellent. The job was completed in 1 day with a great team. Very expressive.
Daniel Perez was great in coming out to check the problem I had with a water leak from my air conditioner line. His recommendation was correct.
Great and informative service while I was in a bind without a functioning water heater.
Plumbing Express is my go-to plumbing support team. They have fair pricing, well-vetted technicians, and a truly exceptional scheduling system. Rod, my technician, was the best. He quickly assessed the problem and gave a fair estimate, working hard to keep to the schedule. He even brought Josh along on the day of service, and the two of them worked well together. They addressed the bathtub drain repair with expertise and caused the least sheetrock damage. It was difficult to replace the broken pipe and get to the upstairs drain, but together they made it a success.
Daniel did a great job and was very professional during his service call last week!
Rod and Josh did an awesome job taking care of my clogged sinks. Knowledgable, professional and great to work with - I really appreciated their help today and would highly recommend them and Plumbing Express!
Daniel was excellent. The work he did was simply superb. I highly recommend your company and hopefully Daniel will get more and more work
Dylan from Plumbing Express came over and replaced our garbage disposal for us. It was older, had a massive leak, and needed to be replaced. He did a great job and was in and out in about 30 minutes! I also asked him to check out a potential leak I had been hearing in my ceiling. He used a thermal camera to investigate and was very honest and upfront about what he found. Rather than immediately cutting into the drywall to confirm something uncertain, he explained that the sound could simply be pipes expanding and that opening the wall might be unnecessary. He recommended monitoring the area and waiting to see if a wet spot appears, which would clearly indicate an actual leak. I really appreciated that he didn’t try to upsell or push unnecessary work. Overall, great service and a great guy. They will definitely be our go-to plumbing service from now on.
Once again we had some problems under our kitchen sink so we called Plumbing Express who were able to get us on their schedule pretty quickly after these storms Tim Robinson came out to do the job. Tim has been to our house for a number of different plumbing problems. He is personable & professional. As usual he did a great job even though this particular problem turned out to be far more difficult than anyone had expected. As frustrating as it was, Tim worked through it until he finished the job. We can't thank him enough.
Anthony was very competent, professional and friendly. He answered all my questions throughly. Highly recommend!
Frequently Asked Questions: Failing PEX Systems
Are all PEX pipes at risk of failure?
No. PEX is a broad category and most systems perform as intended. The documented failure history in residential plumbing is concentrated in specific products, primarily PEX-B crimp systems from NIBCO, Zurn, and Viega/Vanguard, and older colored PEX in dyed formulations. If you have a different PEX system and it’s performing without issues, this page is not describing your situation. If you’re unsure which system you have, a Plumbing Express estimator can confirm it during a free in-home visit.
Which PEX systems have had documented problems?
The systems with the most documented failure history are PEX-B crimp systems from NIBCO, Zurn, and Viega/Vanguard, all named in settled class action litigation. Older colored PEX pipe (red, white, and blue formulations) installed after approximately 2010 has also been associated with failure reports in some homes. In both patterns, failures tend to cluster geographically in subdivisions where the same installer used the same products during the same construction period.
How do I identify what type of PEX system I have?
You don’t need to open any walls. Every PEX pipe has a continuous print line stamped along its length, required by ASTM F876 and repeating at intervals of no more than five feet. Check two easy-access spots: near the water heater, where pipes are often exposed, and under a bathroom or kitchen sink where pipes come out of the wall or cabinet. Shine a flashlight along the pipe and run your hand over it.
The four-digit material code. After the brand name, look for a four-digit code. Common examples are 1306, 3306, and 5306. The first digit indicates chlorine resistance, tested per ASTM F2023: 1 is the lowest rating (pipe tested at 25% of its service life at 140°F chlorinated water and 75% at 73°F cold water), 3 is moderate (50/50), and 5 is the highest (100% at 140°F). For Metro Atlanta homes on chlorinated municipal water, the first digit is the most consequential number on the pipe. The second digit indicates UV resistance, reflecting how long the pipe was tested for sunlight exposure before installation; this matters more for pipe stored or routed outdoors than for in-wall residential systems. The last two digits are usually 06, indicating standard pressure capability (160 psi at 73°F). Also look for ASTM F876, ASTM F877, and NSF/ANSI 61 (the potable water certification). Crimp systems often list ASTM F1807; expansion systems often list ASTM F1960. A production date or lot code near the end of the line helps estimate the manufacturing year.
Fitting type. A crimp or clamp fitting has a visible metal ring (copper, brass, or stainless) compressed around the pipe at each connection point. This is standard in PEX-B systems from NIBCO, Zurn, and Viega/Vanguard. An expansion fitting has a larger-diameter collar at the connection with no external metal ring. The two look distinctly different side by side.
Pipe color. Older dyed PEX comes in red (hot lines), blue (cold lines), and white. Current Uponor ProPEX is undyed. Pipe color is a useful starting point but should always be read alongside the print line and fitting type, not on its own.
Installation era. For the clusters Plumbing Express sees most often in Metro Atlanta, the relevant window is approximately 2000 to 2015. Permit records can help confirm when your home was built or repiped.
Putting it together. A NIBCO, Zurn, or Viega stamp combined with crimp fittings, a chlorine resistance code of 1 or 3, and a 2000-2015 installation date is worth a professional assessment, especially if any neighbors have had leaks or a repipe. A code-5, undyed, expansion-fitted PEX-A system is a meaningfully different situation. Markings alone don’t predict failure, as water chemistry, installation quality, and age all factor in, but they tell you which category your system falls into.
Take clear, well-lit photos of several sections of the print line and the fittings. Include a coin or ruler for scale. If you’re unsure what you’re looking at, include the photos when you contact us. Our estimator can often identify the product and assess the risk level before arriving.
Should I repair my leaking PEX or repipe the whole house?
The right answer depends on your specific system and failure pattern.
One isolated failure in an otherwise sound system. An isolated fitting failure or pinhole leak in a relatively young PEX-B system may be repairable. If the system shows no other signs of stress and the failure is genuinely localized, a repair is a reasonable first response. Your estimator will tell you honestly which situation you’re in.
Two or more failures in the same system. Multiple failures are a systemic signal, not bad luck. The antioxidant depletion and fitting corrosion that drive PEX-B failures affect the whole system under the same conditions, not just one section. Once you’ve had two separate failures, the cost and disruption of continued repairs almost always exceeds the cost of a planned repipe accumulated over the next two to five years. More importantly, you lose control of the schedule. The next failure happens on its terms, not yours.
Failures in older colored PEX. If your home has red, white, or blue dyed PEX pipe installed after 2010 and you’ve seen any unexplained moisture, staining, or pressure changes, an in-home assessment is worth doing.
Failures in a subdivision cluster. If neighboring homes have had failures in a similar system, treat your situation as elevated-risk even if you haven’t had a failure yet. Planning a repipe before the first failure is a significantly better outcome than emergency replacement after water damage.
What does Plumbing Express install when replacing a failing PEX system?
We install Uponor ProPEX or FlowGuard Gold CPVC. ProPEX is Uponor’s current PEX-A product, undyed and manufactured to current formulation standards. FlowGuard Gold CPVC is chemically inert to all forms of water disinfection and carries a 30-year manufacturer warranty. Both are turn-key installations with drywall repair, texture restoration, and paint blending included. See our PEX-A vs. CPVC materials guide for a full comparison.
