When a kitchen sink is earth bonded, is it sufficient to simply connect the cable to the cold water pipe under the sink via a bonding strap?
The reason I ask is that the mother in-law has just had this done and the sparky has done just that. My thinking was that the sink has to be physically bonded as well via a tag fitted to most sinks during manufacture. Just connecting the pipe would not properly bond the sink as well in my mind.
Any thoughts?
