There are two valves and both need to be closed.

You have two valves: on the flow and return. If you turn it off, you will cut off the flow of water from the CO. Loosen the breather - the excess water will come out and that's all. You are replacing the breather without any problem. Buy a new one and do not play in the gasket itself - good luck.

Welcome. Everything above to do, in addition to unscrewing the breather, make sure that the valves have worked properly, in the sense you closed them completely. Open the vent as you would like to vent the radiator, the water should flow a little, it can possibly very gently trickle. greetings

Try to use WD on the shaft and turn the knob a few times - by closing and opening, it can calm down.

Good day.

the radiator vent in the bathroom began to leak.
The radiator looks like this:

I understand that there is nothing to tighten it and you need to replace the entire breather or gasket?

Now the question:
How can I do it safely?
When I turn the valve on top, the water will drain from the radiator?
When I turn the valve on top, the water will not run out, but will not break under pressure when the vent is removed?

What are you doing?

Welcome.

Everything above to do, in addition to unscrewing the breather, make sure that the valves have worked properly, in the sense you closed them completely. Open the vent as you would like to vent the radiator, the water should flow a little, it can possibly very gently trickle.

After two days I did not notice the moisture on the valve. I think it's worked out.

Thank you for all the advice and best regards!
