Bonding at sinks?

[SSE]

What is the actual requirement for this now? Quite often I see a 6mm bond between cold and hot pipes in a bathroom sink, en-suite sink & kitchen sink all in the same house, then others you go into only have it at the pipework hot to cold where the main water service earth is? This is in houses that don't have RCD protection on all circuits ie not 17th edition boards. If I come across this in a property and for example I was installing a new circuit would have to bond all the hot to cold pipes underneath the sinks?

OK then who signing it off?

If its youmake sure it complies, if its one of your budies, do the work then let them sign for it.

Happy Days!

Sorry I should have explained it a bit more, I'm an apprentice so obviously I'm not signing off the work my tradesman whoever that is at the time does that. I was asking the question more for personal knowledge rather than one job in particuar!

What year apprentice? An apprentice usually has some overseeing their work for occasions like this.

2nd, I do have someone overseeing that's not the problem, the problem is I'm being told different things by different tradesmen (electrical) in similar situations so obviously someone is telling me the wrong thing. I could easily just go along with what each tells me but I'd rather know I'm doing something right.

whoever is the one that is responsible for you is the one you listen to...

Yes I do. But one day electrician A in the situation described tells me one thing & then electrician B whilst working I am working with him in the same situation tells me the opposite. The thing is they both can't be right and I'd rather do things the correct way.

well who`s the senior of them two?....seems strange though that you get conflicting info from em......one of ems bound to be wrong and on somrthing like bonding n all......best way is to each one about "exported PME" or something like that....see which one seems more clued up about it........

They are both just regular tradesman with roughly the same amounts of years experience!

Oh for gods sake NO!

PLEASE I beg you NO!

Right here's a situation for example: a new boiler circuit is being installed. The consumer unit has mcb's, with no RCD protection at all. We install an rcbo for our circuit. The kitchen sink has the main 10mm earth at it above the stopcock clamped on to the cold pipe and then linked onto the hot. There's another sink in the bathroom where there is no earth link between cold and hote pipes, does it require a link to be put in, yes or no?

If the bathroom installation doesn't comply with the current 17th ed of the Reg's, then bathroom supplementary bonding is still a requirement. Remember that you are dealing with an installation that was constructed to a previous Reg requirement....

You're not doing any work in the bathroom (or are you?) in which case you don't need to consider the bonding in there, you're requirement is to ensure there is main water bonding and any other extraneous condustors (gas, ol and metalwork) are bonded.

Gallagher, what you are describing is a common problem faced particularly by apprentices. You'll be doing yourself a big favour by getting a hold of the updated Regs and spending time reading and understanding "bite-sized" chunks. Issues like supp bonding have always caused confusion (a bit like exporting PME!!!), so it's always good to have actually read the Regulations.

As said in an earlier post, on the job you have to do what you are told to do by your supervising sparks (unless it's truley dangerous!), but keep asking the questions and querying what you don't think is correct - there's many a qualified spark who gets an approach firmly fixed in their mind as being the correct one....and it's not!

Good luck with completing your apprenticeship...it's initially a bit butt-clenching when it's your name that goes on the cert!

Regards.

Interpretation can be a mare

Isn't there a diagram of how it should be done in approved document P?
