Oil line

[johnmcc1977]

Hi

I am have to dig a trench beside the house for a damp issue and to lower the ground level. I have discovered a 10mm copper pipe which I reckon is for the oil boiler.
I am wondering is there away to see if it active without damaging the pipe!?
Also are these pipes pretty tough if moved given it is old and no long has plastic protecting the copper?
Thanks
In advance.

For sure, a 10mm pipe is the usual size - I guess it’s live but no one can tell from here.
Personally I’d use a new length of the coated pipe, without any joins anywhere if possible. Copper seems to fare reasonably well in soil, but certainly doesn’t like contact with concrete!
