A sparks has just done some minor works on the house and has told me the main earth should have 2 x 10mm earth and not 2 x 6mm, even though there's no sign of burning. My query is about where they should be bonded to the gas/water pipe. Currently the earth to the gas pipe is bonded to the outgoing gas pipe at the meter which I believe is correct. The earth bonded to the water pipe midway between where it enters the house in the basement and the stopcock. The distance from where it enters the house to the stopcock is around 7m. I believe it should be either my side of the stopcock or a lot nearer to where the water pipe enters the building. Anyone got BS 7671 handy ?
