Bonding question - sorry

[bigzed]

I'm hopefully going to be rebuilding the stud wall that I removed that was the original meter position but I need to reroute the Feed and Return pipes from my CH Boiler to facilitate this.

Now I know that there isn't any specific bonding to the boiler, seeing as the gas pipe is directly bonded downstairs but if I break the continuity of the copper pipe with plastic, would it be good practice to run an earth wire from each end of the change in pipework to keep any bonding that's associated with the water side of the CH ?

It won't be a problem having the terminals on show as the pipework is going to be totally accessible being surface mounted in a corner of the new cupboard that the wall rebuild will create.

Thanks as always

Nobody ? - pretty please ?

Your post isn't too clear... but I hope you are not planning to use plastic for gas!

And no, bonding at the intake positions will be fine, you are trying to keep everything that could introduce a potrential from outside at teh same potential.

Chances are the 'gland plate' of the boiler (wrong phrase, but where all the pipes go at the bottom) will link it all together anyway

Make sure your bathroom is bonded as well

Hehe - no chance of that Adam It's just the water pipes I am replacing. I have already been informed from the guys on this site that boiler specific bonding isn't required, as the boiler is connected from the met onto the water pipe & the gas pipe. However, once I install the plastic pipe for the downstairs rads, they will be isolated from the copper coming from the boiler, hence I wondered if an earth wire link would be prudent.

edit! Just had a think Would another separate bonding lead from one of the downstairs rads to the met be a better bet ?

Make sure your bathroom is bonded as well

The boiler is in my back bedroom, I have already done the cross-bonding of the pipework to the cpc's of the lighting circuit in the bathroom but thanks for the pointer.

The 17th guide book shows a Main bond from the MET to the radiator output from the boiler, if the incoming services are plastic.

It says
The radiator served via metal pipes will need a bond if the boiler itself is not itself bonded.
However it would be better practice to bond the boiler or a pipe close to the boiler

Just in the interests of understanding, how come plastic gas pipe is okay on the incoming service pipe and not after it?

For anyone whos interested there is an artical about plastic pipes in one of the wiring matters magazines published by the IET.
Here is a link to that artical:
