Kitchen sink earth bonding

[ComeOnSFF]

Hi,

Apols for the long post.

I do small maintenance plumbing, inc quite a lot of taps. I have zero knowledge/experience with electrics so please excuse any misuse of the lingo.

It's my understanding that flexible hoses (the type supplied with many taps) do not comply with earthing and so if there is a pre-existing tap piped up in rigid copper and you would like to replace it and install flexible hoses instead you should not do this if the rigid copper pipework and sink have earthing cables on them as this would break the continuity...?

However I've also been told that bonding kitchen sinks/taps is no longer done/considered necessary. And so presumably in many case the earthing cables that remain there are not necessary any more and have just not been removed.

What I want to know is - as someone with no electrcial knowledge - is there some visual inspection I can do of the consumer unit or whathaveyou to know that I can safely install flexible hoses? And conversely a visual inspection I can do to confirm that it would be unsafe to?

Any advice gratefully received.

Thanks

Glad you popped up. What is the latest version of ET101, 2008 I believe? Is it similar to 7671 where there are other Guidance Notes and would a new copy incorporate any amendments or are they separate.

The latest Edition is the Fourth Edition, which is ET101:2008. The current Amendment is Amendment 2 (2016). These are printed on the ETCI's (Electro-Technical Council of Ireland) website and can be downloaded free to insert into the Rule book. However the ETCI has now ceased trading and the ETCI's TC2 which is responsible for the Wiring Rules is now operating under the NSAI (National Standards Authority of Ireland) banner.

There are no guidance notes as such published.
