The Water Dept., are going to be replacing the metal pipes in our village
with plastic and state that anyone using the mains for an earth will have to
change. My house was built in 1966 and has a copper supply pipe.
I see that there is a wire from my electrical consumer unit securely clamped
to the sheath of the incoming electric cable so am I correct in assuming
that the house is adequately earthed?
All internal water pipes and fittings are properly bonded.
