Hi all,
Recently had an oil boiler moved to make space in the room, the plumber that did it insisted that the oil pipes need bonding however I'm not so sure. Property has TT earthing. My understanding was that pipes generally only need bonding if they are extraneous, i.e. are metal and run underground. However the oil pipe from the tank is a plastic coated microbore copper pipe, and it runs from the above ground oil tank over maybe 5 metres on top of old stone paving. Basically it never actually goes underground and even if it did its plastic coated.
Previously the oil pipes were actually bonded however practically every visible bit of copper pipe in the house is as well so think there's been a bond happy electrician at some point.
I know the only way to know for certain is to carry out a test however would appreciate any input based on the given info or if anyone knows if there's different rules for bonding oil pipes.
Also another question is if they do need bonding, the 10mm conductor is now a foot or so too short since moving the boiler, so what is the best way of extending it? Replacing its entire length would involve pulling up floorboards so not a preferable option. Plumber has currently left it not bonded as he didn't have any kit to extend the conductor.
Thanks for any advice!
