Press stick against it and an ear, if water you would hear flow when a tap is run or the CH etc.
Aha, will try that when next there. Thank you.

Metal detector might allow you to trace its route in the concrete back to the source, assuming the concrete has no reinforcement and the pipe isn't too deep.
If it is a single pipe it is unlikely to be part of the CH more likely a cold feed. If the room had another purpose before then that might be a clue. Our last house had an external washroom with its own cold water supply when originally built in 1957. A kitchen extension was later built over the site of the wash room so we ended up with two stopcocks one in the extension the other in what used to be the kitchen in the main house.

It's next to a bunch of pipes carrying everything there is in the property, so that wouldn't work this time. I reckon an ear test is the one option that probably will.

Probably Gass if its near a hearth? I had one of those but when I had gas taken out I had it cut off at floor level. Idiot idea to feed it through the e concrete hearth in the first place. Brian
Anyone with the engineering knowledge you have could use a long wire and a continuity tester to find the other end.
I also have a couple of pipes in my sitting room both originally went to the back boiler tank when there was an open fire, but its been drained from a little stopcock behind a skirting board.
I wonder if you could modify a continuity tester to see where it goes. Of course if it goes everywhere with little resistance that might be pointless, but if its just an orphan it should show that by not connecting to anything. Brian
Why did you have the gas taken out? Isn't it the most economical way to heat rooms, water and perhaps cook as well?
(And it annoys the greenies as burning it produces CO2 <g>)
Turn the water off and the gas, then try removing the blanking plug carefully, to see what's inside the pipe. Smell, if gas should be obvious, if static water filed probably a mains cw feed, if it tries to leak it is central heating.
All the pipes are of course soldered, clamped & then bonded together via the CH, main bonding & equipotential bonding. So how would you do it with a bit of wire?

I have a capped gas pipe in my hall cupboard. Gas was taken out when my mother bought the house to prevent it exploding! When a gas leak was smelt around the paths to my and my neighbour's front door I asked the investigator to see if it was coming from my old pipe. However when uncapped it was dead, and my neighbour's pipe was the culprit.
Has the OP said that there is a blanking plug?
It would be a fair assumption that it has not been left wide open.
OP - is the pipe open at the end?
Or have a soldered end cap?
Its not exactly difficult to work it out.

He says it's capped.
You can usually get soldered end caps off if there is not too much water around. or cut the pipe. The only technique that will make it impossible iwithout excavation s folded, beaten flat and soldered near the concrete.
Go on then, we are all waiting for the solution a solution which doesn't require specialised equipment micro-ohm meters.
