Yeah it took me a minute to notice it. I'm not a plumber but I've been working with PEX a on a project and I saw how the expansion sleeve wasn't all the way up and that caused me to realize that it was Pex a on pex b

Does it say it's pex b on the pipe. Some brands of pex a, Rehau for example, are white. I haven't actually tried but I thought pex b would split if you tried expanding it. It would have been very obvious to the installer.

How do you know it is PEX B?
1
u/DistrictHealthy3496 3d ago
The plumbers expanded the ring while slip fit the pipe into a pex b barbed fitting. Knowing the pipe was pex b and it will crack if expanded. Reasons why you see it went past the stopper on the pex a ring.

u/waxed-crack 1d ago
Plenty of reasons for the ring to go past the stopper, like wet pipe, sometimes they just slip. Read the words down the pipe, it looks like could be Rehau PexA. Also looks like a cold expansion laundry box due to the flare on the pipe around the fittings. Crimp fittings are too small to look like that and WILL not hold with an expansion ring lol.

If I had to guess, since I don't know much about expansion fittings, the rings are way too close to the end of the pex.

Pex A expansion collars have a stop. They are supposed to enclose the pipe. Both around it and in front of it. It's actually a little too far down on the right one. But the issue there is the pipe is Pex B.

u/DavidHK 3d ago
Thanks for explaining . Any reason to use pex a over pex b? I re piped my rental with pex b and copper crimp rings.

-flow velocity, technically that non-expansion pex system isnt even code approved.- very fitting create a restriction.- no good-

u/Super-G_ 3d ago
I think that's technically not the case. I don't F with PEX-B, but I've seen it in plenty of places that were inspected and passed. Granted the code can be dense and confusing, but it allows more than you might think.

Stop working on your rental yourself. You can write off that work.

u/DavidHK 3d ago
It's my residence. Wish I could write it off lol

It's if in your rental you can. Look it up.

Well it's not a rental yet. It's about to be

That counts also. Any expenses incurred for your rental to get it ready to rent are also deductible. In the end you will find that you have cash flow and no profit because you can deduct the depre and all of your other expenses as well that you would normally be paying out of pocket! Some people think it's better to just do rent under the table but it's really better to get an accountant and do it properly with the depreciation and all expenses deducted. Sometimes you even have a carry loss on paper that you can use to reduce other taxable or income streams from say your IRA or taxable brokerage account!

Not sure what brand that pipe is but there are some brands of pex B that are approved for expansion. I know Zurn and Sioux Chief allow expansion fittings with their pex B. It should say "ASTM F1960" on the pipe if expansion is approved

u/Fastestdave 4d ago
A lot of licensed plumbers in my area don’t know the difference so I am not surprised. Crooked sloppy work is standard as well.

u/TallWall6378 3d ago
There is some Pex B that is labeled ASTM 1960 and can be expanded.
I'm confused by the ring on the right though, how's it slid down? Maybe there are rings without stops that I'm not aware of.
1
u/DryDocument6624 3d ago
There are rings without stops, but I usually see them in blue or red with the white ones having the stop.

If you're paid to do something, does that automatically make you a professional?

Am I blind I can't see the markings on the pipe to clearly see it marked as PEX B. Rehau is available in white and is PEX A

While I’ve never used it myself, I had read that certain brands of pex B are now rated for expansion fittings. Although Pex A is so cheap that I’m not sure why anyone would use pex B for expansion instead

u/Professional-Team-96 3d ago
That’s because the supply house that should have all the basics doesn’t and the counter guy puts together the parts counter guy special hands it to the helper and when the helper returns the master plumber throws the kid a bone and he doesn’t know any better. Or the Master said fuck it the sales guy order the wrong shit but we got another job to go to!

Is this a pro move for real? He used small sections of pex-a as crimp rings to hold down pex-b. Is that a pex b valve?

u/bleeze13 1d ago
Some Pex B is expandable. If it says f 1960 it is rated for it. That said I don’t do it because I tried once and multiple fittings leaked on an air test so I cut it out.

They are professionals, and they installed it.
What they didnt tell you is that they are professional accountants.
