Changing soldered joint for push fit/compression

[MK22]

Hello, I have a 22mm elbow copper joint which is leaking. I’m no good at soldering, so I’m wondering if I can heat the joint off and replace with either a push fit or compression elbow instead? Would appreciate any help as not had this before! Thanks.

For push fit or compression you need the pipe clean.
That would require replacing that's section.
Better off heating up and pulling off the joint.
Clean off ( sand)
Re soldier.
It's not difficult.

Thanks. I tried soldering twice and both times had leaks. Not sure why, it’s not the easiest access being right up against a wall. Would pre soldered joints be ok to use? Thinking that’s another option

Pre soldered (possibly Solder ring you’re thinking of) need the pipe clean, fluxed, clean of dirt/debris et al, no water in the pipe and heat applied.

You can boil and bubble solder.
I try not to use heat and solder at the same time. You do but be aware.Go easy.
I remember my first attempt running 2 bath tap.About 8 joints and 7 leaked. I enthusiasticly heated and dumped solder on joints but the heat was too much so it just run out and bubbled away. All the copper was red hot.
Trick is to heat steady. Test solder without heat.
Soon as it melts take heat away and don't put back unless you need to.
Just need to relax and be sensible.
Watch video.
Have another go. Think about the heat.

Have you got a photo, just to see where it is positioned?

Cheers guys. Had another go but no joy, think there’s an issue with the pipe. Plumber required!

You have to remove the old joint. Pull it off.
Sometimes you can get a fiber or some cotton thread or just a bit dirt inside joint and it was never very good but over time corrosion gets in and it leaks but no amount if heating and solder will fix.
Easy way is to cut the section out and throw.
New copper and joists.

I would fit a compression fitting with a smidge of portable paste.
I had a plumber round for a boiler fit a few years ago and he always used paste on compression fittings even though you don't need to. But he said when he does he never gets called back for leaks.
He was old school I suppose
