Hallo Sparkies,
I have just replaced my watermain. It is now run in plastic. Previously it was 15mm copper and was earthed to an earth block by the meter. Two adjoining pipes supplying hot and cold water to a downstairs sink were cross bonded to each other and then to the incoming water main.
What should I do now, should I connect these remaining copper pipes back to the old earth lead which is still hanging about so to speak or, should I just leave them as they are. Looking at the rest of the installation overall if I leave it, although there is cross bonding at various points, including on the central heating flow and return there would be no connection back to the incoming supply at the meter which would seem to be pointless.
The gas main has it's own earth connection back to the same earthing block
At the supply head the earth is connected to the neutral
