Have either of you actually either been involved with earthing of gas supplies
NOT OUR MINDS; IT IS WRONG. IT YOU WHO IS WRONG.I have always maintained the gas supply should be earthed after the meter and it is this that seems to wrong in yours, and Johns minds..
As you know, 'remaining polite' is part of my nature (at least, how I try to be!), and I usually succeed - but I have to say that this discussion has been challenging to that philosophy.Alan: I don't know how I am managing to remain so polite.
For what it's worth, you're actually wrong there, at least on two occasions. Just over 30 years ago when I moved into my present house, I installed Main Bonding (which was needed) to an incoming LPG pipe (in the right place, since those who installed the LPG stuff didn't do that - and, similarly, I installed a main bond (again needed, and installed in the right place) to my natural gas supply in my previous house - since there was no bonding when I moved in.Have either of you actually either been involved with earthing of gas supplies I am aware John has not ...
After 12 pages you are still calling it earthing.Depends upon which end you are looking at. I described the pipe as going downwards from the meter and pray tell me where I have EVER said this pipe should be earthed I have always maintained the gas supply should be earthed after the meter and it is this that seems to wrong in yours, and Johns minds..
I think my fundamental misconception was in believing that those that were giving out advise on this forum, allbeit a DIY one, particually those who appeared to have in depth knowledge of the regulations were in fact in some way professionally connected with the profession. However the earlier post from John showed otherwise.Alan:
Is your thinking caused by a fundamental misconception?
I cannot think of any other reason for your continued lack of understanding and refusal to use the correct terms or even topology.
Are you thinking that 'bonding' is applied to metal supply pipes in a property to 'protect' pipes which exit the property for the benefit of people outside, instead of the correct reason which is to protect people inside from low impedance paths to earth through pipes which enter the property?
OK wasn't trying to imply anything just asked. 30years ago interesting probably steel service pipe. Had you still been there and if it was steel I would have suggested that you have it checked as steel pipe is no longer acceptable for new installations since (again from memory) the HSE instructed LPG suppliers to have metal service pipes replaced with MDPE following major fire caused by corroded metal piping.For what it's worth, you're actually wrong there, at least on two occasions.

I'm not sure whether or not you are clear about the two houses I mentioned....30years ago interesting probably steel service pipe.

The other main participant in this discussion, EFLI, is "professionally connected with the profession". albeit he fairly recently retired.I think my fundamental misconception was in believing that those that were giving out advise on this forum, allbeit a DIY one, particually those who appeared to have in depth knowledge of the regulations were in fact in some way professionally connected with the profession.

It's interesting to hear what you say about steel LPG pipes corroding - since, ironically, Calor have started telling me that the MDPE may need to be replaced soon "because it has been in the ground for 30 years"!

Probably under the stairs! the steel pipe would have presumably come up (EFLI) threaded at the end and would nornally have an insulation bit at that point. The steel pipe was normally wrapped/covered in some insulating material. The pipe would then feed into the meter via an emergency valve to a 'gas type' soldered fitting to the meter, through the meter and out again via a lead pipe.I'm not sure whether or not you are clear about the two houses I mentioned....
My previous house, which I bought about 40 years ago and move out of (to present one) just over 30 years ago had natural gas, undoubtedly supplied through steel pipe (in fact, I strongly suspect that it was the original 1920's gas supply installation). However, despite the fact that it needed it, it definitely had no main bond (nor any evidence that it ever had had), which is why I installed it myself.

That's in part really because all quotes I have made have been deemed irrelevant or the writers of them have no idea what they are writing about.If some of the other electricians here had not kept away (probably because of the length and nature of the discussion)
