    A house has incoming water in copper to the stopcock not far from the floor. Then after the stopcock piping is in plastic, however some upstairs piping is in copper again.

    The water has no bonding atall at present, would a bond to the incoming copper be all thats needed or would i need to bond the sections of copper aswell. Thanks all

    Bond to the copper incoming only, but that may change when the 18th comes out...

    Great, was leaning towards that but thought to ask you sages of old. Never come across this before, suppose alot of houses are like this now with people going in for plastic pipes :)

    Many new have blue plastic water main incoming. I haven't seen one "plasti-bonded", but I bet someone has :rolleyes: .

    I have seen one...but to be fair,it was by the sparks admission,a way of "keeping it from flapping about..."

    He said it was a 10 meter run of 10mm to the MET,and he didn't have the heart to cut it off,flush with the mortar,around the ducting that the new water pipe come through.

    I have also seen,in an airing cupboard,where there must have been at one point,six 15mm pipes,all with bonding clamps,and a rarely seen continuous piece of 6mm going on,to the loft...all but two pipes were replaced for plastic,so some dude put three clamps on each remaining copper pipe...quite neat,too :)

    If the incoming water pipe is metal and accessible to touch then I would bond it before it turns to plastic only.

    My plastic incomer is bonded just above the plastic - thats because out incoming mains failed after I had rewired it!;)

    How about, just do a quick test? That'll tell you everything that needs/doesn't need bonding.

    Have you tested the copper pipework after the stopcock to see if it rates as "extraneous metalwork"

    No Pete I havnt', the 7ft of plastic pipe after metal stopcock would surely prevent the occasional bit of copper pipe elsewhere being extraneous, its a small house with just one water supply.

    Probably have it tested in a matter of minuets then, an you've got a no if no buts answer.

    Right, but if you are concerned, a simple test will set your mind at ease surely?
