1st, I HATE plumbing. I can do it all but only do plumbing if I can get no one else to do it. When I have too, I 100% always watch fittings for a minimum of 3 days for leaks. I put paper under fittings to monitor leaks. And use a mirror with light to visually inspect any/all joints for a minimum of 3 days before calling it good.

I think most leaks show upon installation but are so tiny they’re not recognized. Then 1-2-3 years later..... the leaks become obvious.

Unsoldered copper pipe and unglued CPVC (the worst possible water piping choice) can do the same thing.

I will not install any other type, it has proven itself to me and have had zero issues with it. If this product fails it was install incorrectly.
For a man in the plumbing business, the cost of the Uponer tool is a good investment. For the home owner it's very expensibe. Good crimpers, ratcheting or the standard crimpers plus as above good brass couplers make sense and work great.

I offer ALL types of piping ...Too bad my customers are NOT choosing uponor ...

Good thing about Uponor is you have to be certified by the Manufacturer

Here we have to put 200 lbs of pressure on pex jobs for inspection. The joints that haven't been crimped will definitely show.

Back when qest was being used , I put 300 lbs on a system and had no leaks.

Qest is polybutylene- not PEX, but kind of similar. Qest supply tubes were the best, much more flexible than the PEX ones.

I had the flared end of a qest toilet supply tube come loose. Threw a bunch away and never used another.

Why don't you like CPVC? Its all we use in apartment builds.

Not if they’re done right.
Most leaks we come across are because the tube is cut crooked, the tube/fitting alignment is on a curve or bend in the tube or the crimper is out of adjustment.

Avoid the thin copper rings.
Best is the stainless steel Viega style sleeves or Uponor expansion type connections. Both take specific tools.

Lots of reasons, but mostly because it loses its plasticity over time, especially on the hot side. After ten years the stuff will crumble if you try to cut it with loppers.

Flowgold is used here, with copper second. Just saw a new system with a nylon looking pipe buried and a home run from every supply to a manifold...not Polybutylene.Color coded for hot and cold.

That makes sense. Most of the developers we build for flip the property as soon as HUD regulations will allow them to so they DGAF about those kinds of things.

That’s what the go no go gauge is for ... If used should always be confident in crimp.
