Size matters?

[Bas]

I've come across a mains supply pipe which is copper with a black plastic sleeve. The question is that the copper excluding the sleeve has an OD of around 15.6mm - too large for a compression fitting stop cock (the existing stopcock is knackered and I only have an inch or so of the copper to work with.

Can anyone advise the best way to deal with this apparently oversize pipe?

Thanks in advance.

Yousure it`s not black Alkathene with a copper liner

ive had inch pipe of which ive needed to file so as to fit 28mm conex.can u get all around the pipe and whats its wall thickness ?Before u try , enquire with local plumbing supplier whether or not they have a fitting for it.doubt it though.

Thanks for the replies, its not Alkathene just normal copper with a soft black plastic outer probably to protect it as it runs through concrete, I thought about filing it but its risky as ther eis little room for errors. I'll probably refurbish the old stopcock.

fit new one above old

Have a compression fitting for such a pipe.

No need to file or mess about with it. Just slap it on and torque the capnut

Unfortunately the pipework goes directly into some boxing so it's not possible to add a second stopcock.

Refurbish it is I think!

Remove the boxing. Then fit new above old.
