OK, fitted a new compression elbow but managed to find a 3/4"olive in my stock. seems to have worked. Thanks again.

Thanks for all your advice, has helped a lot as I originally had no ident of the pipe and of course was puzzled as it didn't fit new stuff. Will let you know if it leaks!

Can only read Prestex England on nut, any numbers obscured, no numbers on tap. To complicate things I have to fit an elbow where tap is to get round new pipework that gets in the way & cannot be re-routed. Other forums confirm your indent of pipe as 1/2" Alkathane class C or D, giving an O/D...

Would love to, but not an option. Thanks

My mistake, it does measure 22mm [/img] This is image of current fittings, close to floor as you can see.

About 4 cm exposed, so size mark is underground! That the modern piping is 20 or 25 mm is what prompted the question! Mine definitely measures 20mm. Stop cock looks to have typical yorkshire compression type nut, presumably with an olive. So perhaps a 22mm compression fitting will work?

Original pipe seems to be metric (22mm diameter, not 3/4"). Think I will try a Yorkshire fitting. Thanks for reply.

The incoming main to my house (built in '80s) is black plastic and measures 22mm diameter. I wish to move the attached stop cock so need to extend plastic with 22mm copper. Anyone know if I can use modern plastic push-fit fittings on this older plastic pipe?
