Cheers mate. You remind me of my NIC inspector with that 'however' ....

If you know that the water is plastic then can you not disconnect your earthing conductor and perform the test as per post 5 and 7

" ie the water and gas pipes are both connected to the boiler so I would end up also testing the water pipe (which I know is an extraneous part):

Don't think he said water was plastic?
The point I was trying to make was -- if? it isn't extraneous then it doesn't need a main bond...........however lol..........

It will be connected to the main earth via pipes/boiler etc (inside the equi zone) so during fault conditions blah blah it will rise to mains voltage and is sitting there on a nice 'wet' concrete slab attached to a great big metal gas bottle with loads of lush wet grass next to it.

Same as running a copper pipe to your garden hose really if you think about it lol.
Ahhhh..........rcd will cover that though surely

Two of them actually, ....and in series with each other, if i have read the OP correctly!! lol!!

As our learned colleagues have stated, give it an IR test between the pipework and the earth point. If greater than 23Kohms bond it, if not leave alone else you could be introducing an earth potential!

Not a caravan man myself but if the bottle is on a concrete base I cant see how it will introduce an 'earth'?

oops ..... seem to be out of synch with this thread somehow! All the answers have been given ......

Are you sure your statement is correct?

Double oops ...... good spot, should state that less than 23K needs bonding!
