plastic pipe stuck inside copper nut & pipe

Looks like nut and olive to me.

I'm seeing part of a bottom-entry filling valve that has been sheared off at the connector, probably by overtightening, i.e. tap connector with a fibre seal. If you look carefully, you can see that the plastic has a thread on it.

yes, the plastic pipe has a thread which the nut is attached to. It's from a regular water feed to the ballcock

Sorted ?

Not yet, having to come back to it this afternoon.

This what it's from, snapped at the bottom thread as I couldn't loosen the white plastic nut at the bottom of the cistern ( schoolboy error )

Aye. Can see the plastic. But what I can't see is a soldered tap connector. Which is why I suspect nut and olive. Also wrong type of nut for a tap conn.

 

[Popzdad]

I'm suspecting it must be a nut & olive due to a) plastic and nut both spinning and b) getting nowhere with tapping it upwards. If this is the case what can I do? There isn't enough copper pipe to cut under the nut and rejoin to the new plastic valve. Please tell me in layman's terms

Blow torch on it. Melt plastic. Tap down. Cut olive off and new nut and olive.

Alternatively get yourself a 15mm x 1/2" flexible tap connector. Cut back copper pipe and assemble. Making sure you don't over bend or twist the flexi.

I can see the thread, but I cannot see an end-feed or other joint where this supposed tap connector is going onto the copper tube, hence my theory is nut and olive straight onto the plastic thread.
At this point, if it won't tap off, I'd say either a flexi as other have suggested, or cut the nut with a hacksaw and bend it off the plastic thread. At least then we'll know for sure if it was a nut and olive or not.
But don't use a nut and olive on a plastic-threaded fill valve, or this will happen again.
