How to connect black water main plastic pipe to 22mm Copper pipe

Thanks Denso, I'm wary of dismantling everything and then finding I can't put it back together again :)
Here's a closer picture - does this help?

I've looked at the black pipe again and can't see any writing on it. I doubled checked and it's 27mm diameter.
 
I'm pretty sure it has a reducing set therefore you "should" be able to just dismantle the fitting, remove the reducer and reassemble with 22mm copper and a new 22mm olive.

If I recall correctly, Black alkathene was 22mm (a lot of the one’s I’ve been to have been). If this is the case then a 22mm stopcock would suffice. There’s usually a bit of writing on it, but you say there isn’t? Not many combi boilers specify 22mm, what boiler make and model?
 
From 2.45 onwards, same principal. You can hopefully see at 4.00 what I think I can see on yours.

3/4 inch - so a 3/4 olive in a 22 fitting will work;)

Yes it does - that's a 22 coupling with the reducing set. The clue is the shape of the nut on top - changed from flat top to shouldered when metric came in - when I started plumbing as it happens;)

Think the OP has measured it and confirmed it is 27mm. Don't know if there is an alkathene size nearer 1" or a metric equivalent.
 
That'll be 1 inch alkathene the OP has. Sorry for confusion, I was replying to chris_w about alkathene . .;) NO - I was wrong , thanks Jim Crow below

I dismantled the connector and there was a 15 mm reducing set fitted. The 15 mm pipe and top piece of the set came out easily but the insert was a nightmare to get out (it took me several hours). Luckily it eventually came out with an improvised "puller" and the 22 mm pipe and new olive fitted perfectly.

Water softener is now commissioned and working and the wife is happy so thanks to everyone for the advice.
