Hi,

Is 15mm & 22mm copper pipe smaller than the old imperial 1/2" and 3/4" pipe.

I ask because I put a 22mm tee with 15mm branch onto a friends hot water
pipe the other day using compression fittings and it leaked like a sieve. I
did note that the existing pipes were a much thicker wall than the modern
22mm pipe
