6mm Microbore

[doitall]

C'mon now chaps don't show your lack of knowledge & experience........................Of course 6mm WAS used in microbore systems.

Is there any fully qualified time-served real Plumbers on this site??!!!

Yes Dick and real time served plumbers would laugh at you for even thinking about using 6mm.

I never said I ever used it, but it was used. Seen a few houses with it and, if you can read son look for yourself;

6mm has a very poor heat carrying capacity, most installs have many small rads. Even seen it fitted between T&G flooring, time was money even back in the 70's!!!

Maybe, maybe not, but you implied that time served plumbers would approve of the cr@p

A real time served plumber wouldn't go anywhere near it.
