Help Identify This Pipe Type

[Stu86]

I have this grey plastic pipe throughout my house in 10mm, 15mm and 22mm sizes. I'm planning to renovate my bathroom, but I can't find any manufacturer markings on the pipe itself. The only markings I see are some part or certification numbers which i cant find any info on but some text is in in polish?

All of the plastic fittings I can see around the house are grey Hep₂O fittings. The house is UK build from early 2000s and from what I've read, the older grey Hep₂O system is compatible with the newer white Hep₂O fittings.

I've never worked with plastic plumbing before, but everything I've read suggests that the pipe, inserts and fittings should all be from the same manufacturer.

Given that all the existing fittings appear to be Hep₂O, can I be reasonably confident that the pipe is Hep₂O as well and safely use the latest Hep₂O inserts and fittings?

Or would it be better to connect to the existing pipe using compression fittings and then run new, identifiable pipe from that point onwards?

I asked at my local plumbers' merchant, but unfortunately the young guy behind the counter did have any ideas.

Thanks for any advice

I think it's safe to assume that. The important bit is matching the inserts to the pipe, just make sure thety are a snug fit. The fittings aren't so important.

Great, thanks. Just one other question. Would you recommend using the new-style Hep₂O inserts with the existing grey pipe, or would it be better to salvage and reuse some of the inserts from the current fittings?

The inserts that are already installed look slightly different. They appear to be smooth stainless steel, whereas the new Hep₂O inserts have a textured top and ribs along the sides.

If the pipe does turn out to be the older grey Hep₂O, are the current inserts and the latest inserts interchangeable, or is it safer to reuse the original style where possible?

Thanks again for the advice. I'm just trying to make sure I don't create any leaks

are the current inserts and the latest inserts interchangeable

Yes, no problem.
