What is this?! Gas pipe?

[Sally Waite]

Update - the pipe is dead! I can hack out the concrete and hacksaw it off below floor level, then put a plug of cement and pva or similar (as insurance in the very rare event there is some sort of leak in the street and it tries to escape through it)

That’s great Sally, hopefully it didn’t cost you anything?

 

[Sally Waite]

Nope, all gratis. Good result! Thanks for all the advice here.

Why wouldn't you wind it out with some 24's and put a plug in the elbow under the ground?

Yes, you are right. Assuming it is not bent.

As per Razor, use some Stilsons and try to turn it anti clockwise to unscrew it.
