Query regarding Earth Bonding

[Unfinished]

I have just replaced the bath - but there wasn't any earth bonding. Where can I buy the clamps and what do I ask for?

Is it OK to run the earth back to another pipe which has a clamp?

For the radiators - I assume that as long as both sets of pipes are connected and earthed that's all that's needed?

Thanks

your local electrical factors.
Earth clamp. Possibly 'tenby style earth clamp'
Note that ones with a blue label instead of a silver one are
made for damp conditions (the galvenising is thicker, so they cost 50p each instead of 30p)

X bond in 4mm or thicker from metal pipes whose fittings (taps radiators etc) can be touched to the earth cores of all circuits that enter the bathroom (e.g. lights/showers/ water heaters) as appropriate. DO NOT run a separate bond back to the main earth, this is a classic gotcha, under a fault it can make things worse. (Search other threads for why..)

Consider as well what you are best doing if things are supplied with plastic pipes..

can make things worse can make them better most of the time it will make negligable difference
