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
