    Pipework bonding in flats

    I have measured 0.08 to 0.15 ohms between earth and pipework, which according to GN8 makes this extraneous, i guess its bonded inside the flats which i have no access to. should these be bonded at the communal consumer unit as well?

    Should this pipework be bonded?

    Hi, I was changing my kitchen tap in the weekend and saw that the main incoming water supply was bonded. However it got me thinking whether it actually should be or not, as I was under the impression that the main water pipe should only be bonded if its extraneous, ie if the underground pipe is...

    Testing gas pipework for extraneous conductive parts

    Just checking before I blow a hole in the wall that using an IR test at 500v is ok on bottled gas pipework. Seems like the sort of thing that in hindsight you'd wonder why you thought it was a good idea. Could disconnect the bottles, but that would seem to make the test pointless.

I cannot and have never...

Is this correct or would we be better using the immersion during peak PV production times even if the heating's on as were...
