There was an ancient (1950s) steel pipe bringing mains water into my
house under the front room and then up in the cup'd under the stairs.
There there was a stop cock and it went into copper pipe and onto the
copper a large sleeved earth wire was connected with a tag on saying
"Do Not Remove".

The steel pipe was leaking so I have taken it all out and replaced
with blue plastic pipe. Was looking at the earth arrangement and
wondering if I need to earth the wiring in another way, into the
ground or something, or are we still earthed through the water in the
plastic pipe out to the outside world?

Water is NOT an adequate earth. An old electrical install with no earth
is not safe.


It's not the water which provides the earth. It's the metal pipe in
contact with the ground over a long distance.
