Quick question for the master plumbers here:
The gas supply line from the house connection to the heating system has just been installed on the unfinished floor, so it will soon be covered by the screed. It is about a 25 mm (1 inch) copper pipe with a plastic coating.
At one 90° bend, the copper pipe has slightly narrowed, while all other bends are smoothly curved without any constriction. I would describe the narrowing as a kink, and you can feel that it is no longer perfectly round on the outside but flattened. See photo.
I pointed this out to the installer, but he said everything is fine and there is no problem.
Is this still compliant with standards and safely installed as is, or should it be replaced?

The bend was probably even more severe during installation; once it is bent back it can no longer return to its original shape, resulting in such deformations. If wrinkles form, that is essentially the end of it.
Repairing a Wicuro pipe for a gas line without subsequently installing a continuous protective conduit along the entire length is not allowed.
Since the gas pipe is located inside a “cavity,”
it must be ensured that in the event of a gas leak, the gas cannot accumulate in cavities. This is a regulation.
For example, if a coupling or bend was installed,
this interrupts the insulation, which in the case of gas lines is the protective sheath. Wrapping something around it won’t help.
The only option is a complete replacement. That is probably the reason why he does not want to do it.

What the reason might be that he does not want to do it.Yes, that’s probably the case. He would need to replace it completely, and from what I understand, this was already his second attempt. At least there was another bent pipe of similar length in his vehicle… frustrating for him.What am I supposed to do? If he says it’s fine like that and doesn’t want to change it. He is the master tradesman?! It is difficult for laypersons and clients when subcontractors are hired independently.

Check out the Association of Private Homeowners—they can also assist you. Of course, this kind of service always costs money, but it also provides security.

People can say a lot, including big words like "still within the standard" or the almost Old Testament killer phrase "we’ve always done it this way." That’s why you shouldn’t judge his answer to your verbal question, but rather his response to your photo documentation sent by registered mail with return receipt.https://www.instagram.com/11antgmxde/
