Leakage Near Thermostatic Head After Accidentally Leaning on It

Hello,

The described problem is probably trivial, but it doesn`t bother me, please explain it. The radiator in my apartment was replaced with a new one. The radiator is connected from the bottom. Yesterday, I accidentally leaned my body against the thermostatic head and noticed that a little water flowed right next to the thermostatic head and then stopped. I noticed that the nut located next to the thermostatic valve and the radiator (silver) was not fully secured, so I tightened it until it stopped. Then I tilted the head (in the same way as I leaned against it earlier) to check if water was flowing again. The water wasn`t flowing anymore. The question is why this situation occurred and whether it could be a faulty valve? Does tightening the nut solve the problem and I can sleep peacefully? Thank you in advance for the information.

Hello.
You most likely tightened the screw union.
But it is also possible that the valve itself on the side of the thermostatic tip is leaking.
Wait a few hours and if it doesn`t leak, it`s ok.

I tightened the metal part marked in the picture and it no longer leaks for several hours. Water flowed in a small stream when I pressed my hand in a direction perpendicular to the head. When I stopped it wasn`t leaking.
How to check if this valve is not leaking?

Hi.
If you only tightened the part you marked, you probably didn`t solve the problem. This is only the attachment of the head itself to the thermostatic valve and does not have direct contact with the water in the system. Perhaps the valve is loose in the seat and when you tightened the head, you also tightened it.
Therefore, it would be a good idea for you to disassemble the head. You`ll see a valve underneath it. Then tighten it.
It would be best if you took a photo and marked the location of the leak before disassembling it.
Oh, and when unscrewing the head, be careful that the valve itself doesn`t unscrew along with it, because then you may have a big problem (a giant leak).

Maybe it`s better not to touch it since it`s not leaking? Hmm ??

In a democracy, you can do whatever you want . But you can`t be sure that it won`t start leaking at some unexpected moment. It may be true that when you tightened the head you tightened the valve, but if you accidentally turn the head beyond the resistance, you can loosen it again.
I would check it out for the saint peace.

APPROX. Can it be flooded because of something like this? Is it just a small leak at most?

when water leaks, it may flood something...

Unless you meant this part... Before starting the work, it`s best to close both valves under the radiator. Then only a little water will come out.

What I mean is, if I have it screwed in this way now (now the water is not flowing), could it leak in some uncontrolled way and flood the apartment?

And you know how you don`t know?
Theoretically, it doesn`t do anything by itself, but if it`s slightly twisted, it could happen at any time as a result of some touch or movement. And how will you move and leave the house?
As I said, it`s always better to check and do it properly. There`s not much work to do, but the benefits can be considerable.

Do it as you see fit. Regards.

How to tighten this insert?

Hello,

Today I called the friend who was installing the new radiator and it turned out that after removing the head, the valve built into the radiator was not fully tightened. The valve has been tightened and the thermostatic head has been installed, nothing is leaking. In fact, when removing the head, you have to be a little careful because you can unscrew the valve and water comes out.
