I've seen a sink recently which has copper pipe goes out of the toilet to a connection under the floor which is supplied in a non conductive material back to the main shut off valve. The same method is used from the toilet. To me this doesn't require bonding if there is rcd protection, but it did get me thinking. If the pipe work is supplied in copper then changes to plastic then changes to copper again, how long must the copper are we talking before it is deemed an extraneous conductive part that needs to be bonded?
