I am putting in a new metal sink into a Utility room which is labelled as having to be earth bonded. I have checked the house and the metal sink in the kitchen has no bonding on it, also the taps in the bathroom have no bonding on them. The only bonding I can find is from the water inlet to the consumer unit. The pipe work in both the utility and kitchen is a mixture of copper pipes, plastic pipes and both copper (compression and soldered) and plastic push fittings.
Do I actually need to install any additional earth bonding and if so do I need to link back to before plastic pipe or fittings are used?
