Hep2O pipe and fittings (South Tonbridge TN9)
15mm app 20m of pipe, mostly around 2-3m, one length about double that. Plus about a dozen elbows. Most of the required inserts are either still in the pipe or still in the fittings. I've recently removed this from my central heating (to reroute the pipes), was installed 2020. Suitable for mains water or heating project.
