bonding to water pipe.

[paddyc3112]

I have recently done an EICR test on a flat. The only issue being that the water pipe is not bonded at the stop cock. The stop cock itself is located just outside the flat front door in a service cupboard - the trouble is the pipes are all plastic in the service cupboard and under the floor into the flat.
It seems to be that all pipe on show is plastic, the only copper pipe I have found is in the water tank cupboard which is nowhere near the point of entry or the stop cock and is permanently screwed shut.

My question is where should I bond it?

Should you bond it?

This was my question, I'm unsure because some if the pipes with the flat are copper but all of the pipes on show at taps etc are plastic.

Test it to see if the bit of copper in the flat needs bonding.

Well if all the water services coming into the flat are plastic it is unlikely that anything inside the flat will be extraneous....but then as an electrician carrying out an EICR you will aready be aware of that.

Never assume, always test for metal pipework being extraneous or not, especially in flats and apartments....

Highly likely they arent introducing an earth potential but better safe than sure so a quick blast on the IR meter will tell you one way or other!

If you are not going to test it to prove it isn't extraneous, you will have to bond it.

If you can prove it isn't, then don't.

Parallel paths to earth via cpc's on boilers and such like will obviously make below the required 22k ohms. But if you cannot or will not disconnect them and PROVE it isn't extraneous then bond it.

That's the way I see it anyway...
