Think I would have told said plumber to stick to sniffing gas! There's far more copper in the gas pipe than a 10mm bond cable.So many do not understand the colour codings of clamps. A site that had 50 odd flats I used to do maintenance work on was all like that. One thing that has always bugged me slightly is that the ends of the bond wire does corrode when connected externally, yet no one seems to worry about that.
