Metallic pipe with push fittings

[Paul.M]

I'll dig the book out and have a look for you IQ, interested myself. Have you had a look at the op's other question on the other thread?

I think so if it's the bonding size on TN

In Kitcher's testing book it is bridging a plastic push fit when the pipe is being used as the bonding conductor. May be that should be in the question? Otherwise do nothing. Good old C&G making things clear as mud yet again

Yes, that's what I thought it should be.

If a metallic pipe work has push fit type fittings that dont provide electrical continuity what should be doneA=Leave it as it isB=Increase the pipe sizeC=Bridge with a brown bonding conductorD=Bridge with a G/Y bonding conductor.

So we are all wrong because it does not state in the question what the pipe work has in relation to earthing? There should be another option E= ask the plumber, its his mess

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!
