BigWallop,

Thanks for the reply.

Aren't the pipes bonded? Or are they plastic?

No, the internal pipework is all copper and it is bonded, but not
under the kitchen sink. The connection is in the bathroom.

Is there no earth bonding hidden behind kitchen cupboards or even under the
floor boards somewhere? The bonding straps could have been placed where the
pipework enters the kitchen, rather than being close to the sink itself. Check
along the full length of the pipework from the sink to where pipes disappear out
of the kitchen.

I would advise testing the bonding, but that is not really going to help to
much, so I'll just say then, that it's worth placing a bonding strap on each of
the cold and hot pipework, and then on to the sink in the kitchen. You say
there are bonding points already on the pipework in the bathroom, so this shows
that at least some of the pipes are connected, and it means the kitchen might
also be bonded but the earthing straps and hidden somewhere. Time to get the
torch out. :-)
