is that digging it up then...to see how far it goes or is wrapped etc?
Lol, not across the misses flowerbed !

You've lost me there?? I must be missing something!! lol!!
But i'm off to bed now, i'm actually feeling sleepy tonight. ...lol!!
dig the garden thenLol, not across the misses flowerbed !
dig the garden then
Where can I buy some lead pipe, please?

We have one of those somewhere on here.
I do realise that the services are not there to be used as an earth, and the difference between earthing and bonding, which is why I started all this: testing the effectiveness of my earth twig. I will see if I can get PME'd, which would be the better option, otherwise I'll get some chunky rods and start driving them into the mud-bath that is my garden.
One day I'll get under the floor and individually test all the pipework and find which one is the culprit, but for now I CBA!
how deep have you gone?
Two rods screwed together, so 8 feet.
Exactly, I told you that 'twig's were the way to go.
Wack a 1.2m 'twig' in and the the Ra will decrease because of the contact resistance around the electrode.
Better still, back fill with conducting cement and you've increased the contact resistance immediately.
As an aside, it only works when the soil conditions are right and Hong Kong, Gibraltar and most of Norway plus the Himalayas and a couple of places just outside our local pub are not the best places for any 'twig'
Oh I don't know, all the wee would keep the soil nice and moist! Although may corrode the rod quite quickly.As an aside, it only works when the soil conditions are right and ...a couple of places just outside our local pub are not the best places for any 'twig'
Oops my mistake, they are 5/8" not 3/8". These mediaeval measurements confuse me! 10 or 15mm make more sense to me. (see: What we SHOULD have been taught in our senior year of high school - The Oatmeal )
I will try to remember to retest in a few months time, as hopefully the soil around the top rod will have settled a bit. At the moment with all the movement from driving it in it is flapping like a dick in a shirtsleeve.

I will concede that you are referring to a fully integrated system over several miles - hardly 'twig' territory.
The basic two up two down domestic installation with a 'twig' would suffice, IMO, as long as you get a reasonable Ra of less than about 50 Ohms and as you say this value is likely to decrease as the electrode beds in.
In any case, unless you can get the value of Ra below 1 Ohm you'll need supplementary protection Earth fault protection from RCDs
