What is this?

[Vanheden123]

I'm in the process of tearing out parts of an isolated room inside my old barn. And behind a now dismantled workbench, I found this:
What kind of installation is this?

 

[tergo]

looks like they've put a 10 amp bottom fuse in the pipe

A shut-off valve, (the rosette handle) that is located somewhere below and the pipe going up to get water in, perhaps a so-called winter connection. Someone has put a plug contact 10 amp in the pipe, just like that, it has no function.

Rather a coupling part.
Most likely you have a water post valve under the floor.

 

[Vanheden123]

Interesting!
Yes, it definitely seems to be a passdel.
But then it might be possible that I have running water out in the barn?

The room has a concrete floor and a well too.
The ratten is hardly turning, but maybe I should remove the passdel and dare to turn a bit harder?

The risk is that you may not be able to turn it off if you turn on the water.

There is probably a gate valve down, and then you need to turn it back and forth slightly towards the open position; they can be a bit stiff but do not get completely stuck. Where the spindle enters the valve, there is a packing, likely made of palmetto yarn, and if it has dried out, it will definitely leak when the spindle is rotated. It doesn't spray forcefully but can flow nicely, which is not good.

Okay, very good response here!
I tried turning with a bit more force now and rotated the knob about 1.5 turns. But unfortunately, nothing happened, no water came out.
Wondering what the next step is to try to get the water to come out?

Starting to think if it is connected to the summer water we take from the river via pump during the summer?

I can add that we have relatively recently moved in and don't know much about the history of the outbuilding.

Then it will be necessary to consult the previous owner or see if there are neighbors who might know something about summer water, you probably can't get an answer in the forum about this, just a hint of what it might be.

Try blowing into the pipe. If there's no resistance to build up pressure, you can always connect a leaf blower, compressed air hose, or similar and blow a little moderately. Then take a walk around (on a non-stormy day) and see if you can hear where it's blowing.
