Yes, plumbers know everything!If the pipe is not acting as the bonding conductor then a quick < or > 22KOhm IR test after the first joint will confirm any bonding requirements (highly unlikely).There used to be a requirement to insert an insulating joint in pipework to external taps on PME supplies, I bet a few had 'bonding links' wrongly fitted over the years!
