sealing water and waste pipe in the wall

[kolt]

Hi All,
Looking for a bit of advice. Had a plumber over who put new pipes into the wall (photo attached), unfortunately, the guy that was supposed to do the rest of the work had to leave to Ukraine, so wondered if anyone can advise on the best way to seal/close those.
Thanks

What are the pipes carrying? i.e. both hot water, hot & cold, both cold?
Is the black one an electrical conduit with live cables?
I'm not a plumber but I don't think burying long pipe lengths in walls is a good idea as if the are hot pipes they will try to expand when hot and contract when cooling down. This can cause the plasterwork to move and crack. Also all joints need to be soldered securely, not compression fittings.
If you are determined to seal them in you need to use a flexible filler to accommodate the pipe expansion problem.

Water pipes aren’t supposed to be embedded in any wall or floor as per the regulations.

What regulations are those?

If it’s hidden plaster over it an forget. If it’s on show, we ask the plumber to sink them deep enough to allow plasterboard cover. The copper pipe should be taped/protected.

If it's on show then pipes like that would have to be boarded over otherwise it will crack if you try to just fill it. If it's not on show you can just leave it exposed.

Your link shows pipes set in walls and floors.
