I called the JS corporate office and I was alramed how little their technical staff knew about the product. They don't have basic things like installation manuals. But what bothers me is that he said it so now they just don't know. They said they pulled the product off the market last year and just put it back on in October.I have no opinion on the JS pex...yet. I will be in discussion next week or the week after with a rep for them. I will say that if you are not on a recirculation line, then you would be absolutely fine to use the Uponor pipe and fittings. If you are on a recirc line then you may want to use the Zurn pex B pipe and either the Zurn expansion fittings or the Uponor expansion fittings. Not all Ferguson counter people know about the Zurn expansion. No reason to carry both Uponor and Zurn expansion, especially now that they have the JS expansion, by the way Ferguson owns Jones Stephens and is the largest plumbing supplier in the United states. so they will back up any warranty no problem if it ever happens.
My white Uponor pipe installed a few years ago, and also unused new pipe stored in a low light environment (garage), look like this after a few months. I can tell you however that unused pipe kept in the original cardboard box will stay white; so either light or water will cause them to yellow, but not aging alone. I would be curious to see a picture of the pipe that you said you saw that stayed bright white although it carried water. If that was just a result of the lighting situation when looking at it. I still have some unopened, white/translucent pipe from the batch that yellowed quickly when installed. Would be interesting to install both this and a brand new white version of presumably updated Uponor pipe from 2024, and compare if they yellow at different paces.It's also affecting the white pipe, possibly in a smaller percentage. Someone on this site (I think it was here) posted pics of a roll of uninstalled white Uponor pipe that had yellowed like the sections of failed split Uponor removed from a home.

EDIT: Here is the pic of the brand new white Uponor not even put into service. I had downloaded the picture when it was posted on this site I believe. Of course, we don't know the storage or handling of this role, but it does appear to be suffering the same degradation as the colored pipe.

If it was 100% covered with something, then no yellowing is expected. The antioxidants in PEX and plastics in general only yellow from light or chemicals, as far as I know.I'm not a professional, but I've done a fair amount of plumbing over my 67 years owning many properties and some house flipping. I've pretty much only used copper over my lifetime but about 6 years ago I did some PEX Uponor for a friend of mine who added a bathroom to his first level (raised ranch). At that point I bought a Milwaukee expander and heads and plumbed in my buddy's bath. I've used it a few times since in some minor work.
Last year I saw the Uponor pipe I installed at my buddy's house before he finally enclosed it, and I paid close attention to the color of the 5 year old pipe because of all the hoopla about the yellowing.
Even though I've been very vocal and critical about Uponor on this forum, I did not see any yellowing of the pipe I installed at that time. The next time I see him I'll see if I can get a pic of where the PEX is attached to the copper.

The stuff is gonna last probably around 35 years .... and then the chlorine will start to break it down
or possibly someone in your local city water company utility will make a bad mistake and throw too many additives into the city water and accelerate the process...
I think if you have a new home with wirsbo pex or some other kind of pex that you ought
to invest in a 2 cubic foot back washing chlorine filter on the in coming line to your home
just to take out all the chlorine from your water to be double sure and
it will certainly extend the life span of the pex....
If your friend didn't cover it during the 5 years before he finished his house, it would have been grossly negligent, asking for trouble. Was it protected?
If I'm not mistaken, testing and extrapolation gives PEX-A a 50 year estimated lifetime under the "worst case" scenarios per specification for pressure, temperature, and chlorine/chloramine concentration. (Although I'm not 100% sure about the conditions of the theoretical 50 year life; please correct me if I'm wrong.)
Most real life parameters for pressure and temperature should be significantly lower than the specified limits.
I'm not sure about Chlorine/chloramine concentrations; U.S. city water (for example Los Angeles) and national limits are more than 10x the limits (for example) in Germany (4 ppm vs 0.3 ppm). I hear that PEX for residential water was only used in the U.S. starting in the 1990ies; so the real data sample of long-term results is not that long.
Nevertheless, if the tests and scientific extrapolations are only remotely accurate and not grossly misrepresented, I would assume at least 50 if not 100 years expected life for most single family home installations. The speed of most chemical reactions increases or decreases proportionally to the square of pressure and temperature, if I'm not mistaken. So 50 psi with a pressure regulator should result in multiple times longer expected life than under marginal conditions close to the design limits.
Well also , odds are we are both gonna be dead and gone before 50 years passes.....
its not gonna be our problem
We have a bunch of homes in town that are going bad where they used some kind of ss clamping ring on theNot me, but there are plumbers who have installed PEX in homes that now requires a full repipe in less than 10 years. I'm 67 but plan on living at least ten more ..
John
now you are 67 and odds are you could make it another 20+ if you take care of yourself , eat right, exercise and stop sniffing
that dam PVC glue every day......you might make it....
But I like sniffing glue!!!
I was born with great genetics - I take only a low dose statin for my total meds and have no pain of any kind, but I realize that none of us are guaranteed a tomorrow. But I do keep my weight in check (not easy) and I do exercise, but not as much as I really should.
Hopefully we'll all be around a long time. BTW, my mom turns 100 in December!
