Here is one wall area I didn't redo. Opened it up due to recent leaks. Wanted to see if it was what I was seeing previously from my first plumber.

Sure enough, Uponor blue colored PEX pipe with copper crimp PEX B rings. Didn't we just cover, thanks to a fellow forum member, that Uponor only makes PEX A? We all can see the copper clamps that were used as I previously mentioned. All of this is getting torn out.

These pics are a mix of plumber 1 and plumber 2. And what brand of PEX is that white pipe with no markings? In one pic I swear I can see it swelling on the hot side. All the white pipe is the hot side.

And notice all the stainless cinch clamps are too close to the fitting on the white no name pipe.

I thought, being a couple sandwiches shy of a party, you used the proper PEX A rings with A pipe. And B pipe with clamps. Learn something new again.

For the record, Uponor blue is fine with B copper clamps?

All PEX can be crimped or cinched. Only PEX A can be expanded. (Exception being a select few B manufacturers that are rated for expansion.)

As far as copper rings I thought they were fine with Pex A or B as well, crimps and clamps regardless of there type metal I think are ok above ground no idea about below ground usage. the color of the pipe Ive never heard matters either.
Originally My understanding was Uponnor could be joined with any of the methods and type B was limited to non expansion methods. I belive only some Type A pex is now allowed to use expansion.

I figured if you have PEX A pipe you must use A clamping devices. B pipe the same, B clamps. Trying to learn about this. Thanks to all offering some wisdom.

Pex A can be crimped without issue
Not trying to argue but why would in my case a pro plumber buy PEX A pipe and use B copper rings? Isn't A pipe more expensive than B?

Not that it matters. It's all coming out anyway. I had a plumber do this while I was at work.

Why would a pro plumber use crimps would be my questiom? Maybe he felt like you didnt trust expansion? or he dosent trust it? but nothing wrong at all with crimping type A or B
Maybe I missed why you are working on the system ? looks like slab leak repair on copper pex ran overhead as a re route

I am removing all Uponor pipe from my house. No leaks as of yet from the pipe. Simply to make me sleep better LOL. That and I like learning about things and doing it myself. Running Sioux Chief PEX A and Boshart stainless steel fittings. Oh and Sioux Chief copper manifolds. I've picked up a lot of flow removing all the restrictive B fittings for sure.

I'm not a plumber. All of those numbers stamped on the PEX pipes tells you all you need to know about the pipe and what fittings you can use. Take the numbers printed on the pipe and do the google.

I think uponor actually makes a type of crimp or cinch ring but I've never used them. Sometimes I go to a job and someone did the whole project in pex b. I'll hook pex a to pex b using a cinch ring and then expend from there. It's fine.
