Gas or Water Pipe?

[Mondamoser]

Hi all,

First time post so please be gentle.

Trying to ascertain if damp wall in our kitchen is being causes by rising damp or by a seeping pipe.

The pipe in the image attached disappears off under our solid kitchen floor (back addition of a 1890's Victorian terrace). The other end disappears underneath the floor in the other direction, BUT I can't find it reappearing anywhere else in our accessable crawl space and it doesn't appear to be linked to our current mains water or gas system (as far as I can tell, but it's a real maze under there). I also can't find any appearance of the end that goes off under the kitchen floor (as pictured).

Therefore I'm wondering if this pipe is now redundant as part of a previous system that got updated at some point which would lead me to think that it might not filled with anything.

I've tried turning on mains water and it doesn't seem to be flowing in that pipe, but there might be a very slight vibration in there when mains water turned on (if I'm not imagining it), which makes me wonder if it might still be filled with water but just capped off somewhere under the kitchen floor (and maybe seeping, causing the damp problem).

However, my main question is... Does this pipe look like it is a Water pipe or Gas pipe?

Many thanks in advance for any help!

is the pipe before the coupler, in the lower half of pic 3, plastic?

Hi, thanks for your reply.

No it's not plastic, both sides of the coupler are metal (lower half has been curved).

What are your thoughts?

Many thanks again

I'd guess water, it also seems to be partially insulated.

Have someone turn various taps on, whilst you feel the temperature of the pipe, it will suddenly go colder, if it contains water. At this time of year, left with not water used for an hour or two, the water and the pipe, will be warmer - so the difference will be more obvious.
