Plastic to copper bathroom tap connection

[sahar]

Hi,

Does anyone know how to remove this type of connection as on the attached picture please?
This is a bathroom tap connection, and the top copper pipe is a direct connection to the tap.
Want to replace the tap and that connection to add a shut off valve and a flexible pipe but not sure how to actually remove the existing connection

thanks

Not sure but they look like old marley push fit's, they are supposed to be demountable but it's getting a tool that'll fit it. Just cut it out, simplest way.

Osma Gold - `15mm Stem Elbow into 15mm Coupling, you will need to cut it from the piece coming out of the wall.

cheers guys, sounds like a real pain in the neck to get a new tap connected then ....

Not really, water off, pipe slice/hacksaw in behind the elbow and cut the pipe and then replace with compression/pushfit.

As MikeCip says, now obsolete Osma Gold, you can take them apart by using a Demounting spanner (or circlip pliers.
But get rid of it, they had issues of the "M" ring (not "O" ring) failing after systems had been depressurised/ pressurised several times.
