Apologies if this has been covered before. I don't log on too often
I was taught ( more than a few years ago) to specify a T fittings with 22mm ends and 15mm middle as
End x End X Middle i.e 22mm x 22mx x 15 mm
Now I am told I should be using End x Middle X End = 22mm x 15mm x 22mm.
When did this change ?
