Bonding or NO bonding

[NozSpark]

On a similar subject and hopefully not more "cannon fodder" Slightly knowledgeable builder asked me today, why do you need to bond a copper oil pipe that is plastic sheathed. I promptly blubbered an answer along these lines " if the plastic got damaged under ground then the pipe would/could be extraneous" He gave me a familiar hand gesture in front of the customer.Any advice??

Also; We have many bottle gas supplies over here. Do we need to bond the pipe coming from 1 or 2 gas bottles standing outside of a building with the pipe at approx 1m high or higher, passing straight through the wall adjacent to the bottles ?? once again, usually plastic coated (not always)

I phoned the NICEIC tech help line regarding this a year or so ago

My scenario was gas bottles standing on concrete pad outside house connected to valve/regulator via rubber hose and then into house with copper pipe.

I was told it was not extraneous and therefore didn't require bonding.

On your first point I'd say your bang on, who can say for certain the sheath is infact complete & not missing in sections or damaged underground (and I was asked the self same question by my assessor last time out & gave exactly the same answer)

Second point again I'd say yes to the bonding, the bottles are external & sat on the earth with pipework entering the property, no different to any other service pipework entering a property.

Well there you go every day is a learning day........thats what I like about this place always somebody with the corrective answer..

TBH I didn't like the idea though, but getting a bond on to it would have been a right pain!

Why not just test to the MET and see what reading you get.....the NICEIC or the Milkman or whoever ! cant tell for certain, it has too be tested to positively confirm whether it is extraneous or not .
