I have lived in my current house, which was built in the mid 1970s, for
around twenty years. The water pipes have never been earth bonded.
I recently had my old fuse box replaced with a consumer unit and, as part of
the job, the electrician fed an earth cable through into the downstairs
cloakroom, where the mains water comes into the house, and bonded it onto
the incoming cold water copper pipe. He also 'cross bonded' all the copper
piping below my new combi which is installed in the attached garage.
It was not until he had left that it suddenly occurred to me that 12 months
ago I had completely refurbished my bathroom, removing the old airing
cupboard and replacing it with a shower cubicle. Most of the hot and cold
water pipes in the bathroom required re-routing and so I replaced them all
with plastic piping. The incoming cold water supply, and the hot water
supply from the combi in the garage, enter the house via the downstairs
cloakroom, and then go up into the bathroom, and from there down into the
Because I have replaced the hot and cold piping in the bathroom with plastic
piping, there is no earthing continuity between the bonding point and the
kitchen (and no easy way to by-pass the plastic piping in the bathroom now
So, how important is it that the water pipes in the kitchen are earth
bonded - and is there an alternative to getting an earth bonding back to the
consumer unit from the kitchen?
