Connecting into old Telcon 1/2 Pipe Mains

[Harburt]

Hi all

I'm in the midst of replumbing my house and have discoverted this black plastic pipe running the water mains:




I am presuming it's an old imperial standard even though it seems identical to 22mm pipe. Are there any push fit or compression adapters that I could use so I could cut into this existing pipe to add in the bits I need? Or do I need to replace the lot?

It comes in off some 15mm copper coming from the stop cock as per below:




Can I just cut into that 15mm and rerun the whole lot (if necessary)?

Any advice would be amazing

Many thanks

Use 22mm compression fittings and 3/4" copper olives and a short cutting of 15mm copper for an insert.
