    That's what I mean last time I know of a house piped in it was also built in the 80,s mother in-laws house had it end up repiping the heating every time I would visit she would say one or two rads not working got a pain in the arse listening about it redone it and never a problem since, we were told in college back in the 80,s there was a shortage of copper pipe at the late 70,s the price was too high for lengths so that's why it was used we were told I came out of my apprenticeship in 88 and never once piped a house with it only came across it over the years

    No, I meant houses built SINCE 1980. Including noughties houses ( the plumbing in these has generally been awful, but no flow issues in the ones I have worked in, even though they were in 10mm).

    Over here 1/2 inch would be the standard practice for the rads as I said when came across it we would remove generally blocked ,do you remember the same end twin feed rad valves .absolute ***** last job we came across it was in very expensive houses in Dublin city a builder came in and removed a rad to put patio doors in and just turned the valves off and buried them in concrete no rads would work it was effectively a one pipe system and with the rad removed it wouldn't work **** job for a 1,000,000 pound house plumbing just as bad a lot of cowboys around then and not enough sherrifs
