plastic pipe stuck inside copper nut & pipe

[Popzdad]

Advise urgently required!
Whilst swapping over the filling valve in my toilet cistern the old plastic pipe thread has snapped and got stuck inside the copper nut and around the copper pipe ( hope this makes sense, have look at the attached photo ) Any suggestions to getting them separated? I only have basic tools and hope they'll be enough.
Cheers in advance

Spanner below and tap it upwards.

I would go with that too to begin with.

To be honest though, by now I would have cut it back with the pipe slice, shot an isolation valve on and had the water and kettle on.

I tried that earlier but it's not budging. The nut and plastic pipe are spinning together but refusing to come off the copper pipe.

Screw fix run flexi 1/2 to 15mm comp and a pipe slice 15mm

My first thought was that could be a tap connector, so you can't just tap the nut off (though it doesn't quite look like one if I'm honest as there is no joint where the tap connector would have been soldered to the pipe). If someone had some kind of crimping tool I'm not familiar with then perhaps they could have formed theor own tap connector? Seems unlikely.

Assuming then it is a nut and olive onto the plastic (wrong!), you probably don't want to cut the nut, unless you have a spare, but that is an option. So best bet is grip the pipe firmly, adjustable held under the nut and whack the adjustable with another spanner or similar upwards a number of times until it shifts. Then ensure you use a BRASS tailed fill valve if you are making the connection with a nut and olive.

Are we allowed to recommend flexis on here? I thought the collective decision was that they were nasty things?

Do you have a hair-dryer that you can use to warm the nut? This should soften the plastic to the point that pushing down on the nut will slide it off the (now soft) plastic thread. You should then find it easy to remove the plastic.

Done this way, you'll be back on track to replace the float valve like-for-like but you'll need a new fibre washer, which you can get from a plumber's merchant.

Be careful not to burn yourself on the hot metal or plastic. Hair-dryers can get things suprisingingly hot.
