Is this old grey Hep pipe?

Can anyone confirm if this is the old style grey HEP pipe?

Pictures of markings attached. It’s marked as Polska Instal??

If it’s is old style HEP pipe I believe I can use the new white inserts and white fittings.

It could be Hep2o, the H and V depth insertion markers are consistent with their markings, the black print on the pipe would suggest that it’s “Standard” pipe and not “Barrier” pipe.

It should have “Hepworth“ or “Hep2o” printed on it approximately every metre or so.

If you aren’t able to identify the pipe you can use brass compression fittings with copper olives and stainless steel pipe inserts, don’t use jointing paste.

It does look like it, but a google search of Polska install suggests it might not be, so could be imported. As per Sandy, could use compression fittings, or take a chance and use Hep/JG fittings.

As suggested, HEP is usually marked HEP2O .... It could be polypipe too - If you show us a fitting we will be able to tell you ... as long as the fittings were matched to the pipe of course

Hep²O doesn't have white plastic inserts. They would be Speedfit.
Hep use stainless steel inserts.

Post a pic of any joints/connections. Might be Osma Gold.

Obsolete if it is

Cheers for ideas. I was working from the room below. Going to lift the boards above and see what I can find. Caught covid so knocked me off my feet for couple of days.

Can’t find the 22mm at all but found 15mm spurred of to bedroom rad. Going to use that instead and feed two very small radiators. I think, because if the size (1kw each) they won’t cause too much issue for the 15mm pipe.

If when it's done , you have a small length of pipe spare - hold it and blow across the open top. The Old Grey Whistle Test.
