Extraneous part issue?

[LastManOnline]

A customer rearranged some kitchen units, exposing a copper section of the main waterpipe. It's just over a foot long(rest of house is Qualpex). However it's unbondedI carried out an Fli test and it maxed out. I next carried out an IR test and got a, reading of 7000 ohms. A little high for a waterpipe I thought. Double checked with a second test and got same reading. OK, a little bit of copper pipe running in some very dry concrete.
However the reading is still way to high to leave it unbonded and the CU is right at the other end of the house.

What other options might I have?
Get a plumber to replace the copper with Qualpex?
Bond the copper pipe to a local socket?
All suggestion welcome

Cover it in insulating tape?

I don't understand it when you use simple language Lucien.

Do you mean 'Introduce a jacket of insulating swathe'?

but not any old insulating swathe. got to be M&S swathe. (what is swathe? ).

I shouldn't admit this but my brain wandered to trying to think of an inexpensive plumbing accessory that requires an earthed electrical connection that could be installed inline on the pipe and legitimately powered by a spur....thus bringing the potential to earth down so when you test it its suddenly fine...!
I couldn't come up with one, a two port zone valve locked open was the closest I got!

Can you earth it before it goes underground? Hopefully the pipework continuity would keep it under 0.05 ohms.

You'd have to ask Lucien!

self tapper through pipe, ring crimp to stop the leak. (well, wet-pants screw up our gear. REVENGE TIME).

I just hope that stop cock won't need 'taping up', too.

Stop cocks are like RCDs. They sit there for years and then you want the untested thing that has had no exercise to actually do something useful and nope....either stuck solid or leaks when you move it.
