The ironic thing was the we needed a bit earlier and we went and
raided my grandfather's celler (all sorts in there if you can find
it!) We found the only bit of 28mm that he had, which was
literally about 4 inches long and just enough for what we needed
(or so we though!)

Hmm, I certainly did mean 1". I thought it was 22mm that had no near
equivalent, but that 1/2"/15mm and 1"/28mm were reasonably
interchangeable.

Old 3/4" bore is nearly but not quite, hence the need for an adaptor to
successfully solder it, the same as 22mm OD

One more grunt when tightening a compression fitting, so I err, found
;-)
