Hi
First picture shows my gas pipe earthed just by the meter, with a safety connector attached to a G&W earth cable. I am 99% confident this earth will be good because I don't think it has been touched since my flat was re-wired by a qualified sparky, maybe 5 years ago.
Question - Since a visual inspection cannot give me 100% assurance that this is actually functionally earthed (that is to say, in terms of actual physics, it is doing what it is intended to do) - Is there any way I can safely test this myself?
The second picture shows my mains water where it enters into my flat. The pipe to the far left going out of the building is copper, it has been painted white. So the arrangement is, from L to R, copper -> plastic coupler -> copper -> plastic mains stopcock -> copper -> pressure valve -> copper pipework extending to kitchen sink area
I think the plastic stopcock was installed after my flat re-wired; I think when the re-wire was carried out, the stopcock in place was a traditional brass tap type.
Questions - Should the copper to the left of the stopcock be earthed?
Should the copper to the right of the stopcock be earthed?
The pipe running vertically in the second picture is the same gas pipe as shown in picture 1, which I believe is earthed.
If the water copper should be earthed, then would an acceptable solution be to use safety connectors to directly connect the water copper to the adjacent gas pipe? This would be a very short cable run, and I presume it would work, but I am not sure if there are risks that I'm not aware of with this approach, or if every earth fitted has to run back to the MCB.
Many thanks for any advice given, which is much appreciated.
