Extending Earth Wire For Sink
We have recently moved our sink, the current earth wire is no longer
long enough. What should I use to connect a new piece of earth wire to the old piece in order to extend the earth to the new sink, and save replacing the whole earth wire back to the consumer unit?? Any help appreciated, Cheers, James. |

In a similar solution, I soldered the wires, crimped them in a brass tube, then screwed the tube flatter using a 30A choc-bloc connector. Overkill? Seriously though. Soldering, or crimping are both acceptable. Choc block connectors are not AIUI. You should probably check that it is in fact properly connected in the first place to the CU. Out of interest, where is the sink?? Because if i is in a kitchen there is no requirement to bond it. -- Steve Dawson |

Sinks don't have to be earthed. Indeed plenty of opinion says it's a bad idea. -- *Two wrongs are only the beginning * Dave Plowman London SW To e-mail, change noise into sound. |

Extending Earth Wire For Sink
Hi all,
Thanks for the comments and sorry for the delayed reply have been busy fitting the new kitchen. I decided to run a new earth wire in the end back to the consumer unit. The old earth was attached to the cold water supply pipe and the sink. I assumed I would have to earth the Hot, Cold and sink. Is this no longer the case? Bad idea? The main stop cock for the cold mains water is not by the sink it is under the stairs although I am not 100% sure if it is earther there or not (am at work now so can't check). I was going to bond the hot pipe, cold pipe and sink are some/any of these required. Thanks for the help, James |

By cold supply pipe, I mean the rising main, i.e. the cold water pipe, within 600mm (I think, or something like that) of where it enters the house (and it sounds like this is under the stairs). You do not need to main bond anything else. If you do, then at best, you'll just confuse the next person to look at the installation. Gas pipe? |

You do not need to bond anything else out of the subset you have described. But you need to bond the gas pipe. And, apparently, metal waste pipes, if you have any... Ben |
