I want to get a pipe that runs up one of the walls in my flat removed, as I
think it is no longer in use. It looks to my untrained eye like lead -
meaning presumably it's at least less likely to be in use. Does anyone know
if there's a way to tell whether there's any water going through it without
cutting into it? I've attached a link to a picture, below for anyone who
wants to hazard a guess as to what it's made out of.

If it is lead, then the surface will be very soft and easy to scratch. If you
had to work hard at getting it as bright as in your photos,then I suspect it
might be galvanised steel.

If it is in a flat then it could be serving somone else above or below yours?

Can you get to one end or a tee junction to see if it has been connected with a
wiped joint or a screw thread?
