Location of Earth Rod

[m4tty]

Hi,

Is there anywhere that an Earth Rod isnt allowed to go?

Ive banged it in underneath the patio step. Got a reading of 33.1 ohms which can be accessed by lifting concrete slab up. No inspection pit just underneath step. Is this ok?

Thanks

And one last question which I have asked before. Bonding to lead water pipe and iron gas pipe.

It will be alot easier to bond to the lead water pipe as it runs underneath where the new cu is going. I know for a fact that the wall on this lead pipe is 8th Inch thick so will not crush. Ill prob ring the elecsa assessor up as he will be the one who passes me (hopefully) so its his call but half before said its ok and half said its not ok.

Like a lot of things in this trade people do things differently and how they have been taught. I just wish there was a definite right or wrong.

Thanks

make a note on cert, and maybe a note on the CU with its location, and you should be fine. maybe even a 'earth rod' plate attached to the concrete step?

As Andy says.

As for the main bonding connection to the water pipe, it has to go just above the stop valve where it enters the property ,or as near as practicable if you can't get at that position. Fitting it before the valve is not correct.

I understood that we were not to put earth clamps onto lead pipework but should employ a plumber to let in a section of copper for the purpose. I generally fit them on the understanding that the lead pipes are supposed to be removed anyway due to prevent lead poisioning.

i know someone a while back who had a lead supply pipe, and wanted it replaced. not living there at the time, he didnt use any water for weeks/months, and the first water out the tap went into sample bottle

apparantly, he should be dead through lead poisioning, and the pipe was replaced fairly quickly!

Bloody hell !!!!

Bloody hell !!!!

re-read the post Deke!

I'll bond it after stopcock then thanks and with the gas is it bonded just after meter ? Cheers

The reg. is actually fairly specific :" bond to consumers hard metal pipework." Lead is soft metal.

TBH, I replaced my plumbing when I first moved in, and we had lead incomer. Sweated a joint no prob; though you can now get compression lead - alcathene.

You can get a "lead-lock" fitting for lead to copper too.

Through the incoming mains cable comes to mind:coat:coat

That just reminded me TTd a garage once SWA fed, segregated at Garage CU

Banged in rod just outside Garage, Earth lead in to CU, did RA test (Loop tester method) and got 0.58 ohms!

"Umm thats a bit toooo good for TT" dug down a bit and found rod had shaved thru SWA outer sheath and was in solid contact with Armour!

Learnt the lesson always check where your supply cable runs!

good thing it wasnt a few mm further into the cable!
