Earthing under the kitchen sink

Charlie_2018

I have recently moved to a new place and there were two earth cables hanging loose under the kitchen sink. One I connected to an earthing clamp just above the stopcock. However I was wondering if it was still necessary to put one on the hot water pipe as hearing conflicting advice on this.

More specific advice may be here soon but earthing the hot water will do no harm and cost very little whilst potentially protecting from serious harm.

It used to be that everything metal got bonded to everything else. But that's now considered unnecessary.


If the incoming water pipe is metal, then it should be bonded for safety.


But just bonding random bits of pipework within the property isn't done any more.

Bonding, not Earthing. It is incorrect to suggest that unnecessary bonding can do no harm. It introduces a potential where it doesn't already exist. It needs to be determined whether these are extraneous-conductive-parts or not.
