Good Evening
New to the forum and was hoping some of the knowledgeable people on here could assist with a query on main protective bonding of sprinkler system pipework.
We look after a number of schools as part of various FM contracts and have had fixed wire electrical testing & inspection undertaken at the sites when required over the last 10-15 years. On a few of the EICR's we have received recently it has been highlighted that their is no main protective bonding to sprinkler system pipework, in the sprinkler pump house or where it enters the main plant room within the main school buildings.
This has never been picked up before and as it seems to be the case that their is none present at sprinkler pipework within any of the schools, I was wondering if their could possibly be a reasonable explanation that at design stage, it was deemed there was no requirement for this pipework to be bonded.
Thanks in Advance
