Electrically speaking, it should be as close as possible to where the pipe enters the property - which would usually mean 'before' (upstream, 'supply side) of an internal stop valve. However some, maybe many, interpret the regulations as saying that is should be on the consumer's side of the stop valve!Should the earth be after the stop valve or is it okay where it is? I suspect the former. Thanks
where is it?where it is

Bonding should be as near as possible to the point of entry to the building…..if there is a meter the connection should be before any pipe branch work…….where practicable, it should be within 600mm of the meter outlet union, or at the point of entry to the building if the meter is external.
The words "stop valve" or "cock" are not mentioned.
Kiriakov, you havent told uswhere is it?[/quotewhere it is
Kitchen. Cheers
It certainly is to me - and, as I wrote, there is absolutely no doubt that, electrically speaking, bonding should be connected as close as possible to the point of entry. However, you go on to cite the reg:544.1.2 is very clear.
All true, but you omit from the quote the main bit you see people arguing about. If there is a meter, bonding should be connected to the customer's hard metal pipework. I am not suggesting that I agree, but you will find people arguing (here and elsewhere) that the pipe from the meter to a stopcock is "the water supply company's" - so that the "customer's pipework" must start after the stopcock. ... and please don't shoot - I'm just the 'messenger'."Bonding should be as near as possible to the point of entry to the building…..if there is a meter the connection should be before any pipe branch work…….where practicable, it should be within 600mm of the meter outlet union, or at the point of entry to the building if the meter is external."...

Yep - I do, and so do both of my daughters, to name but three - so it can't be that uncommon!Does anyone have a water meter indoors?
That makes four, and counting ....Yes internal meter
The exposed parts of all of your electrical appliances (and, almost inevitably, because of the CPCs to boilers, immersions, CH valves etc. etc., also all your internal pipework, taps etc.) will be at the potential of the earth system of your electrical installation - i.e. the potential of the earth supplied by your DNO if it is a TN supply. That potential may not be the same as true earth potential, particularly under certain fault conditions.I guess I need to relearn bonding, but I thought the idea was that your taps etc were the same potential as your electric appliances. Therefore you don't want the resistance of the meter or cock in the way.
I'm sure that's how they'd like to do it, and how they do it with new builds and relatively-recently built properties, but it's less straighforward with very old properties (true of all three I mentioned in my family). In fact, in the case of my house, despite their having tried to find out on a number of occasions, Anglian Water do not know how their water gets to my house, so they could not have installed an 'outdoor' meter in pavement (well, grass verge in my case!), even if they had wanted to.Oh, fair enough. I thought that all water and sewerage pipes etc., unlike electric and gas, on your property were your responsibility and that was why the water meters were in the road or pavement or at least outside your property.
