Hi,
First post so go easy!
Having just fitted a new bathroom suite incl new piping in a bathroom where there was previously no supplemental earth bonding I've been advised to add some.
There are no electrical supplies falling inside the bathroom 'zones' - the only power is a light and pull cord switch which are above and outside zone 3.
All of the piping is copper, with compresion fittings. The bath and sink taps are connected using braided flexibles. I believe that there is an argument that no extra bonding is required since all piping is in copper and is subsequently connected to the main earth bonding outside of the bathroom, however have also read otherwise and it seemed that to install the bonding was to err on the side of caution.
Since the only electrical circuit is the lighting which falls outside of the zones, is it sufficient to connect all exposed pipework to each other, and NOT subsequently to any CPCs as there are none within the bathroom / zones?
Thanks in advance!
