Could have been blue, may have faded. When was polyorc available?Not a clue, only solvent weld pipe I’ve ever seen was polyorc, which was a dark blue colour?
I remember using some very poor quality copper in the mid 70s also stainless steel. Didn't see any plastic before Acorn in 79ish
This is some 'Hunter' pipe [if I recall correctly]. Very brittle stuff, I would avoid it at all costs. I have suggested to several customers it was all taken out and replaced with copper. In 1970's there was a copper shortage after a trade embargo on Rhodesia so other materials had to be found quickly.
I agree repipe Is the best option. Unfortunately the job is a three storey guest house with pipe starting in the cellar!Some of the old solvent weld plastic becomes so brittle you’d be better off ripping it all out and replacing with copper or Hep2o.
Once you start disturbing it you can open a real can of worms.
I recall a whole estate in Runcorn had it all replaced because of problems.
