If there were massive regular failures in soldered fittings, you'd see this discussed on forums, you'd see videos about it, etc etc.
You don't. But you know what you DO see? Sharkbite failures.

Well, the way the person was defending sharkbites like its their firstborn child is why I said they sound like a shill...

The copper in a sharkbite isn't either. But good plumbers will warranty their work. ¯\_(ツ)_/¯

I'm sorry that no one has collected data on every single installation ever.
You can however extrapolate data from anecdotes.

I mean, the data is pretty clear when you search for joint failure in copper pipe and see what people complain about.
If sharkbite is such a great fitting, why don't they warranty it for more than 25 years? The expected lifespan of a solder joint is 50+.

I mean, all you have to do is google joint failure of copper pipe and see what type people are complaining about. And then extrapolate that most people STILL have soldered joints.

Ok, the data shows that we still get more complaints about sharkbite failures now than we do about soldered joints over the last 100 years and sharkbite is still relatively new.

You sound like you represent sharkbite but are posting from a burner account my guy.
Sharkbites fail at the joint, properly soldered joints don't fail much, usually the pipe will fail first.
