This question concerns main protective bonding and which code to use for a PIR. It has been answered by SELECT (Theme – Testing, Tools and Equipment):
Question: I'm carrying out a Periodic Inspection Report (PIR) on a property and have found only one main protective bond leaving the consumer unit (I am hoping that these are linked to both services unbroken).
There are two extraneous services within the property - gas and water. The mains intake for both of these services are inaccessible (kitchen area) and I cannot see the earthed clamped connection. At the water meter is a through link, which is loose, and I would ideally like to prove the integrity of both bond terminations as I suspect they could be loose.
What advice would you give on this matter and what code to use, and would it not be better to urge on the side of caution and issue an unsatisfactory report?
Answer: You can attempt to verify the connections by continuity tests from the consumer's earthing terminal and the service pipe.
You may wish to improve the connection at the water meter first. If the continuity test is successful, then this is acceptable.
You could record this approach as a limitation on your PIR.
