Chase these pipes into wall and behind skirting

[Kaymo]

Hi all,
As per the pic below, I moved this radiator a few years ago from the position where the pipes come through the wall, to nearer the door, so I could put an old piano here. I just used a couple of 90 deg compression fittings and ran the pipes behind the piano, but I am renovating the room now and with the piano gone the pipes will be visible. I'd rather keep the rad where it is, and if I am going to hide the pipes it makes sense to do it before I decorate.

The room these pipes are coming from is at a higher level and has a solid floor, so it would be very difficult to change the entry point, so I presume my only way to hide these would be to chisel as much as I can into the plaster and chase the pipes down the wall then run behind the new skirting. This might be a bit tricky, especially getting the pipe cut far enough into the wall and getting a new 90 deg bend fitted, even if I managed it would not be very deep. Also not sure if there are rules/good practice around connections being buried, imagine at very least it would need to be soldered joint.

Appreciate any comments, might be my best bet is to get another piece of furniture to hide it again!

Chase wall out just above the elbows and use a straight coupling,alter pipes to suit

Given it's microbore then burying shouldn't be an issue. Elbows should be soldered yes. Chase a vertical line in the plaster, clip the pipe to the wall and then use a rebated skirting to hide the pipe.

Straight coupling? I must be misunderstanding this, a straight coupling would bring the pipes towards the middle of the room, surely it would need to be an angled coupling.

Thanks. I have already ordered normal skirting, but I think there would be enough space between skirting and wall as the plaster doesn't go all the way down.

How do you cut the pipe that far into the wall to allow the angle to added without protruding beyond the plaster? Presume I would need one of those small round pipe cutters, and make a big enough and deep enough hole around the pipe to get it in.

How deep would the pipe need to be in the plaster, would a few mm of plaster over it be enough?

I went at this afternoon. Pipes fitted but it was very difficult to see when heating the solder ring joints whether the solder had come out due to one end being in the hole in the brick wall, so just had to roughly judge the time and hope. First time applying the water one of the joints leaked but removed and fitted another solder ring elbow and this time seems to have sealed. Going to leave it for a few days and check for leaks before I close it up and start plastering.
