Polybutylene Supply Line to Copper

[Irelandhokie]

I recently purchased a house that has a polybutylene supply line from the street to the house. The house itself has copper plumbing. I was having an issue with a thumping sound while the water was running that the plumber successfully diagnosed as a bad water pressure regulator. While he was replacing the water pressure regulator, he noticed that the qest coupling connecting the polybutylene supply line to the copper in the house had a crack on it that had been fixed by the previous owner with super glue. He went to replace it with a new qest coupling but it would continue to leak. So instead he put in some new pipe and installed what I believe is a CPVC coupling (pic attached) that seems to have done the trick. I just wanted to make sure what he used is correct?

I have insurance on the polybutylene supply line, so I am not planning on replacing it until it has an issue.

Thanks for your feedback!

That is called a dresser coupling and they are an approved fitting.
I`ve used a few times an never had any problem with them.

As long as the two pipes are secured it is okay, but if they can move the pipes will probably slide out of it. It is a PVC coupling.
