Problem with re-route hot and cold water

[NickB_99]

Hi,

I'm due to have a new kitchen fitted and I'd prefer that the hot and cold water pipes are moved to the corner to be boxed in and a bit less visible. The corner will have a wall cupboard fitted on the wall on the left side of the picture below.

Now I have the floor up upstairs, I'm struggling to work out the easiest solution to achieve this.

Where the pipes start to drop down the wall it doesn't look possible to get in behind to fit compression joints or solder in new elbows.
I could cut this side of the floor joist, but then would miss feeding them down the corner, unless I cut a hole back through the joist. If that makes sense!
Wondering whether plastic pipe would work easier too than copper.

suggestions for a good solution would be welcome!

Extend the existing pipes to the corner & notch the joist there, then carefully cut out the existing pipes with the machine bends & re-use them for the drops in the corner, then all you need to do is connect up with straight couplings

Thanks keego, will go with that, sounds a good solution

Hello all.

Rather than start a new thread, i'll pick up on this.

I moved the pipes, all seemed fine.

Then i noticed last weekend in the new kitchen that some water has found its way down and wet the ceiling plasterboard.

Got the floor back up upstairs, and it turns out the joints are fine, but there seems to be a small weep from just below where the original pipes were bent.

It's difficult to see from the pic, but where the light is shining, there is a tiny hole not visible. When I dry it, you can see a small blob develops that eventually flows when it gets too big.
In its original place, this could have been happening for years. The pipe went right to the floor in the kitchen and the boxing was wide. Now, plasterboard has been touching the pipe, hence prob catching water.

Access is not the easiest.
I am wondering what my options are and if a repair is possible without cutting out the whole right angle?
My concern is that it would be very tough to cut the pipe above the kitchen cupboard, tight on the wall, and join a new piece in.

Whilst I can imagine it's something of a bodge, would a jubilee clip over the top with some filler in there work? Or would some solder cover it, if I drain the section first?

The best option would be to solder over the hole, you would need to drain it down completely for the solder to run properly though.

Ok, can give that a go. Thanks.

Now I'm back from the holiday season, I've got some time to fix this.

As you can see, the access is a little tight for getting heat down there to solder a dot over.
It's also not obvious at all exactly where the hole is - it is so small and I want to ensure I get the solder in the right place. It may be easier to take the L section out and repair it then?
There's already a compression joint on the upstairs section just out of view of the picture. I would only need to cut in the kitchen below after removing the boxing in.
Problem is I can't get access with my pipe cutter or a hacksaw at all.
I've got a Bosch multi-tool - is it possible to cut 15mm copper pipe effectively with a fitting like

I don't want to knacker the pipe and make it a non-uniform cross-section so that I can't solder a new end feed coupling over.
Advice appreciated, especially if this is a bad thing to do!
