OK, thank you, that's interesting. The tap can only be at 0 V if it is bonded; but if the water supply is metal, why has it not reduced the ground potential by the tap? Or is it a plastic supply, and if so does this illustrate that under a rather unusual set of circumstances, unnecessary bonding may be hazardous?
