    Hello
    A few days ago, the cooperative replaced the central heating installation - new pipes and radiators. In the apartment on the top floor, the pipes going over the ceiling to the condenser on the cage have been removed, and in return I have 3 unsightly vents in the premises.
    At the top they have something like this:
    Is the unscrewed vent of the central heating riser a risk of flooding?
    except that for me, this tiny cap at the top is red.
    In one of the rooms it is quite unscrewed, in another it is twisted.
    Is it possible that the team has not tightened something and there is a risk of flooding when they start heating for the first time in the season in my absence?
    A short leak test was carried out, but the gentlemen ran so quickly, then others fell in and twisted something, etc. near the radiators and plumb, that I wonder if they tightened something. Can I just close these tapes myself? Then, however, they will not jump and release air, as it was during the test.

    Unscrewed caps on the vents allow for venting the installation.
    If they stopped snorting, they should be curled up.
    However, it is worth unscrewing them from time to time. This allows for the discharge of air from the installation if it still accumulates in the body of the vent.
    A vented installation heats better.

    And if someone forgets to turn them off, water can flow through them?

    Yes, it can flood the neighbors downstairs, they installed it for me too, and when the heating plant released the heating without warning the residents, it flooded, I personally watered my neighbor, it doesn't go very fast, but after a few hours there is a bit of it and it leaks through the radiator in the ceiling.

    I suggest installing a cut-off valve (ball) between the pipe (riser) and the vent.

    It is assumed that the vent should work continuously.
    Unfortunately, the efficiency of operation varies.
    There was already such a topic on the forum The reliability of the automatic air vent .
    How it works was also discussed Automatic air vent .
    As a general rule, the automatic air vent should not leak water, and its operation is shown in the video
    http://www.youtube.com/watch?v=OdH2DjXnYh8&feature=related.
    Unfortunately, there is a construction difference, but the principle is similar.

    Hello.
    If this red cap is turned off, the o-ring seems to be ok and the water is leaking out anyway, does this vent need to be replaced?

    what is this breather professionally called? how much it costs?

    Added after 2 [minutes]:

    automatic air vent?

    can it be replaced if the heating season has already started without draining the water?
    it is located on the last floor in the residential side, the entire riser is vented.

    Usually complete with the valve is the so-called foot valve. So below what you can see in the photo there is still a hexagonal element and only the thread of the installation screwed into it. If this is the case, you can unscrew the valve.

    1.that is, even though the water is now coming out (in small amounts) ... when unscrewing the vent, this foot valve cuts off the water supply and you can easily screw a new one ...?

    2. is there any chance that after removing this valve it can be resuscitated somehow and it will work again? (clean, blow)?

    It should be like that. This is what the so-called footer.

    Rather faint. Anyway, the cost of a new one is low, so why?

    Buy a decent branded, e.g. afriso for PLN 20-25, and not a Chinese for PLN 10-15, because the cheap ones are leaking from new products ...

    I have loose nuts and so it's been a year :)
    My question is can they be covered? build over? Can they break down and start pouring water, which I will not see because they will be covered!?

    At my house I once forgot to turn off and before a few days the pressure from the furnace was dropping and the floor was a bit wet

Topic summary

The discussion revolves around concerns regarding unscrewed vents in a central heating riser, particularly the risk of flooding when the heating system is activated. Users highlight that unscrewed caps on vents allow for air venting, but if left open, they can lead to water leakage, potentially causing damage to lower apartments. Suggestions include ensuring the vents are properly tightened and considering the installation of a cut-off valve to prevent flooding. The reliability of automatic air vents is also discussed, with recommendations to use quality brands to avoid leaks. Users express concerns about the possibility of water escaping if the vents are not adequately managed.
