Copper pipe 15mm burred shower mixer fitting

[Stoptheleak]

Hi, hope all is well!

I’ve fitted a compression cap on two of my shower mixer copper pipes (15mm). One of them has scratches and burring and is very slightly out of shape. It leaked but I added some PFTE tape over the olive and it seems to of done the job. However…

I’m tiling the wall and before I do I wanted to ask if you guys thinks it’s safe to move ahead and fix a new shower mixer onto that pipe? Or should the pipe be replaced? It’s only sticking out a little so I can’t cut it to get a better part of the pipe to fit onto. Can a new piece of pipe be added without retracing it back into the wall and creating more work?

Any advice would be a great help!

If it was on a job of mine I would cut it out and replace with fresh pipe- a few minutes work and very little cost.
A leak inside a wall, very disruptive, damaging and expensive to fix later.

This is a no brainer - do it properly.
