This sort of piping is banned in the USA because of catastrophic

No, that's polybutylene. That is a totally different
plastic, normally terminated with crimp fittings.
It is completely different from what we use,
which is polyethylene with pushfit or compression
jointing. They call our polyethylene/MDPE pipe PEX
over there. It is widely used, but not as widely
as over here. They still use the crimp fittings, though.

Go to the web sites of the main players of plastic pipe fittings in the UK.
Hepworth for e.g. Do a search on "polybutylene", and lots comes up. From
the Hepwroth web site:
"Hepworth Underfloor Heating Pipe is manufactured principally from
polybutylene"
