Earthing/bonding the kitchen sink

[keenamateur]

Hi

is it neccessary to bond a stainless steel kitchen sink from what I have read elseware it is not necessary.

Can anyone confirm this?

Why do i ask - well I live in a new build house wired by NICEIC firm and both my sinks are earthed- sort of - to a plastic screw!!!!!!!!!!!!

Also do you need to bond where an electric immersion is? ie to the switch terminal and the pipes - copper of course.

Thanks

no you dont need to bond kitchen sinks anymore

the other bonding could be supplymentary bonding for the bathroom because the bathroom needs to have supplymentary bonding to all the pipework, metal bath and any electrical circuit contained in there

Hi

Thanks for a fast response

The other bonding is not in or near a bathroom FYI - so is it neccessary?

 

[Gaz the Sparky]

that could be part of the bathroom bonding its there for a reason so its best to just leave it alone

Hi again

I didn't intend on altering any bonding, just trying to understand the reasoning behind it - its miles from the bathroom (not literally) relatively

no you dont need to bond kitchen sinks anymore

If this is the case why was it once done? and why is it not anymore?

Thanks............... anyone [/quote]

There are still plenty of sparkies in this town working to a conglomerate of 15th and 16th edition and a few ideas of their own thrown in. I come across kitchen bonding all the time. I just keep my mouth shut, only a dumb plumber as far as they know.

It was once done as it was deemed "necessary". However, the theory now is that if it is present, it may create parallel earth paths which can actually be more dangerous than there being no supplementary present.

Thanks -

I had a look in my mates rented flat - and to comply with a test required for the council - the company that did the test have joined up the hot water cylinder hot and cold pipes and the kitchen sink!!!!!!!!!!!! with earth wire
After having failed the flat and charging big bucks - for what seems unecessary work.

all very recently

Funny old game electrical work

Council want their socks pulling up..

Concils are getting too much power.

Over on the plumbing side some local council has banned slotting joists for pipework. That's all very well for plastic but what about us craftsmen that use copper. I suppose the council won't have any problems with me using plastic for my gas then.

Other option (to having multiple joints out of reach) is to drill a hole in the outside wall and pass your pipe along through that.
