Advice on making this connection..

[Le Rouret]

Hello....it’s nice living in France...apart from the plumbing...I need to connect to the chopped pipe....the pipe in front will be removed...I think I can solder it...just...any hints or tips ?
I want to avoid concrete bashing...
Thanks

At a glance, hacksaw blade, file and a compression fitting spring to mind. What does it carry and where is it.
You may need to bash concrete.

Thanks for reply...
Under shower tray...hot water....not sure I can solder as access is tricky..will try compression and push fit and if not enough room solder and if that fails out with the power chisel...I challenge anyone to find anything worse than French plumbing...electrics are worse..

Meh, he says whilst shrugging his shoulders.

Don't think you'll be doing much with it before opening up the area. Don't let the bits go down the pipe.

Use an expanding tool to form a socket or solder in a pipe the next diameter down.
The concrete shown can mostly stay in place.
