15mm Copper pipe stub comes out of concrete floor & is capped. Tracing it is therefore not practical. Question is, what plumbing circuit is it part of? CW, HW, gas, CH primary? Is there any way to find out other than the messy way?

Press stick against it and an ear, if water you would hear flow when a
tap is run or the CH etc.

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.

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.

Why did you have the gas taken out? Isn't it the most economical way to
heat rooms, water and perhaps cook as well?

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.

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.

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

Is there any way to find out other than the messy way?

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.

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.

Anyone with the engineering knowledge you have could use a long
wire and a continuity tester to find the other end.

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?


NT

Its not exactly difficult to work it out.

then you can tell us.


Well the first thing it will tell you before you disconnect anything is
if its connected to any other pipe work which is the first step.

Now I will let you continue with step two if it doesn't read anything or
if it does read something.

It's connected. It wouldn't be there if it wasn't. What is your step 2 with this bit of wire?


How do you know its connected?

If its mains water you aren't supposed to leave long dead legs as they
are a breeding ground for bacteria.

Why did you have the gas taken out? Isn't it the most economical way to
heat rooms, water and perhaps cook as well?

Its not uncommon to remove gas fires and cap off their feeds when CH is
installed though.

Yes but Brian uses storage heaters. I don't know whether he had gas
central heating before.
