Sorry if I'm asking the same question that has been asked before, but I do find this quite a confusing subject and there are many differing answers . :shock:
I'm re-doing my kitchen and have moved some of the pipework but need to check the Earthing arrangements - I understand that the Kitchen itself does not normally need supplementary bonding, but just want your views on the current setup.
It's an upstairs maisonette, with some fairly old wiring down at the CU, but it does look like some extra earths were fitted not so long ago. I think I need to do the main 10mm earth to the gas meter down in the CU cupboard since I cannot see any in the cupboard, and the new gas meter we had fitted last month got a sticker from the fitter saying he cannot see any Equipotential bonding to our pipes - buts thats another part.:?
Our water main - its a lead pipe coming into middle of house from downstairs flat, which I've joined downstairs to copper pipe via a 'Lead-Loc'. This copper pipe runs under the kitchen floor to the back of the house, where it comes out of the floor to a new stopcock I've fitted. Since this it the first accessible point in the flat - [b]This is where I would attach my 10mm earth which runs up from the CU ? [/b]
This 10mm earth which was previously attached to some of the pipes, was also run along all 5 of my combi boiler pipes - CH FLOW, DHW, GAS SUPPLY, MAINS WATER, CH RETURN.
Would I be best to do the same and run the 10mm Earth that I attach straight by the stopcock, over to the 5 boiler pipes, even tho one is already then attached (MAINS WATER)? ... OR would it be ok to cross link the 5 pipes together with 4mm Earth (using the Combi Mains in for Earth).
With the earth wire - I'm not sure my 10mm main will be long enough to reach - is it OK to join with another piece or what?? Would normal Metal Earth block be OK for this?
Does everything above make sense to you - hope so...and that you can try give me some advice - there are so many different threads around that I dunno what way to go!!
Thanks in advance! :D
