Look at doing some repairs and repairs so was thinging of using this tubing https://www.castorama.fr/tube-multicouche-16-2-50-m/3342971405116_CAFR.prd
Any one have any experiesnce of using this stuff instead of copper pipe.
I have some experience, having completely rebuilt the plumbing in 3 flats with multicouche tubes. I didn't know it was a specifically french thing. I will happily try to help you, but what is your question exactly?

Took photos hours ago, nipped out to escape the house. Bought a baguette, some non blue chese, an electricians knife (not that great but €2.95) a set of measuring calipers, and some nail trimmers for feet, but no box of croisant or pain au chocolat on special!!!. Oh and 10 25cl bottles of kroneborg.
Anyway here are the photos: This is the bathroom in question so you can see how the bath is tiled in.
The inspection/access panel for the ubend, that when i tried to open I managed to knock off all four of the tiles. There is a vent and I have no idea why it would be there.
So removing the panels shows these pipes, both hot and cold that go to the sink and the waste pipe from the basin.
Here are the pipes that are under the bath. The issue is where the bottom water pipe crosses the first upright water pipe as there is no gap between the two and thing there is a leak there hence wanting to replace the two pipes.
There isn't enough space to get a propane torch in there to heat, have a brazing set but not sure adding heat to solder new joints would affect the not very nicely soldered joints so not sure adding brazing torch temps. So was thinking four compression joints and a bit of multicouve with a handmade gentle bend to keep the two pipes apart.
The pipe external diameters from the possible leaking area and the external pipe diameters are 16mm (on the far wall) while the pipes running along the side of the bath (coming towards you) are external 14mm but soldered together with the 16mm. The 16mm, on the far wall, goes from 16mm to 12mm.
Part of me thinks I should cut the pipes along the side of the bath to gain easier access to the possibly leaking pipes then fit compression joints with the multicoude in the middle instead of soldering an inline link.
