I'm planning on replacing a bedroom radiator. Because of sizing differences that are unavoidable, I need to adjust the pipework. I'm planning on changing the last metre to the radiator to use plastic pipe connected to the existing copper. Plastic will be easier for access and minimising joins. What I can't understand is if I would then need to bridge the copper flow and return together with an earth cable to maintain a circuit that the plastic pipe will now break? Can anyone help please?

+1 ..... Where plastic pipe is used then supplementary bonding isn't require after the pipe as anything after the plastic is, in essence, isolated from any potential power source.

As said the problem is when a copper pipe transmits a fault to another room, with plastic pipes that can not happen, no need for earth to radiator.
