The main issue was your contradictory and confusing statements, "22mm is
the nominal bore size" and "All 22mm pipe are the same OD", clearly
those 2 statements are mutually exclusive.

Why is that? Don't you understand the difference between bore and OD?

I'm afraid I misread your post, it wasn't contradictory, it was simply
wrong:

22mm is not the "nominal bore size" of the pipe as you stated, it is the
outside diameter.

The o/p will be using 20mm o/d MDPE pipe in a compression fitting
designed for 22mm o/d copper pipe and will need to use the 20-22mm olive
previously referred to by Andrew.

Let's hope that clears things up.

You really are a f***g half wit rambling on about topics you have zero
knowledge about.

He will be using 15mm pipe. The 22mm fitting will be neccesary because
the MDPEpipe has a very thick wall diameter.
