I am having my house completely rewired and replumbed. Part of the new plumbing is a non-metallic pipe through the thatched roof void to avoid the need for the plumber to use a torch in the roof space. If he'd had to use copper and torches, we wouldn't be insured for fire. All good, so far. This creates two separate zones of pipework. The first, is connected back to earth in the CU via continuity, the second is completely isolated from the CU, because of the plastic pipe.
The pipework at the end of the house that is fed by the plastic roof pipe is not in any way bonded to the main pipe work. My electrician says that bonding is no longer required (every circuit is protected by an RCBO), yet my reading of the Regs is that bonding is required if the circuit doesn't meet the requirements of ADS (which I think it does) , OR it is a special location. The en-suite shower room at the far end of the house is surely a special location?
I checked the radiators and pipework in the end of the house that is served by the plastic pipe, against the sockets at that end of the house, and the is no continuity to earth.
Do you think I need bonding, in which case my electrician is wrong, or is ADS through RBCOs sufficient, even in bathrooms?
Many thanks
