I am having the outside of my house rendered so everything has to be removed from the outside walls. This has all gone smoothly except for one solvent weld pipe (40mm), it has a right angle into the drain but its connected inside the wall which means the pipe work is too close to the wall to get the render behind. Is there any way to connect to the corner without digging out the wall or damaging the kitchen to bring it out 20mm.
Thanks

Connect or disconnect or what?

I am trying to bring the pipe out from the wall. The join is inside the wall so a pipe extension piece wont work. Is there a solvent weld that can go over the old join?

Why would you need to damage the kitchen to extend the pipe? It should
run back to a trap, where there may well be a compression fitting you
can undo to replace all the pipe after that. If the trap is solvent
welded as well, there will usually be at least a short run of pipe where
you can fit a straight socket, to extend the pipework. I would avoid
anything that involves trying to make a connection inside a wall, where
you can't easily check it for leaks.

Assuming the pipe goes straight through the wall to the inside, Id be
cutting and rejoining it inside the house.

You're just not giving the info needed.

No. Once the solvent glue is set, that's it. Only way is to cut it off and
extend.

They don't easily disconnect unless they have been badly made joints to
start with. Easiest would be to cut the pipe inside well away from the
wall, or disconnect if there is a compression fitting to the waste.
Pull out the pipe through the wall from the outside and after the
rendering is done replace the outside pipe and the one through the wall.
At some point an extra joint may be needed if all the outside pipe is
solvent weld, and it may be possible to put a coupler somewhere
inconspicuous. it will be necessary to open up the hole in the new
render and make good round the new outside elbow. With mortar or
acrylic caulk for outside use.

You reckon if cut the elbow in two and split the part over the pipe you
can get it off? I've done that before, but not sure if it's always
possible?

Or the old trick of using a smaller pipe inside the cut off old one of

OP doesn't really give enough detail, but yes that could be the simplest
way.

Copper pipe comes in 28, 35, 42 mm OD with solder fittings available.
With enough overlap, silicone rubber should give an adequate seal. You
can also wrap the inner pipe with PVC electrical tape so as to make it a
tight push fit.

Thanks,
I took your advice and extended inside the house to push it out from the wall, it was more accessible than expected.
