During my work, I experience more and more places, even in new residential buildings, where craftsmen forget to install the air intake valve or forget to ventilate the duct.
The air intake valve is a plastic part that costs a few thousand forints. Its weight and size are negligible, but its function provides a huge help in maintaining home hygiene and maintaining a sense of comfort.
The air intake valve serves, on the one hand, to equalize the vacuum created in the drain pipe, and on the other hand, to prevent the escape of sewer gases and sewer odors. toilet When pulled, the vacuum can suck the water out of the built-in odor traps, which has previously prevented the backflow of odors and sewer odors, thus giving a free path to unpleasant odors.

Where should air intake valves be used?
An air intake valve must be installed in every building higher than one floor, where there is also a wet room on the upper floor. It is also recommended for single-story buildings, although it does not play a major role if the construction is flawless. It must be placed above the last drain branch on a downpipe, preferably the topmost one. toilet in the branch above. If possible, it is definitely worth placing it in the attic, in an easily accessible place. In the case of subsequent installation, the siphon A smaller type of air intake valve can also be placed between the wall connection and the air intake. A clever specialist You can position the air intake valve in a way that will fit in any apartment. Before installing it, you should always consider where it will function most effectively, so it is worth seeking the help of a qualified professional.
How does the air intake valve work?
The operation of the air intake valve is very simple! During operation, the vacuum causes a small rubber membrane to rise, which allows air to enter the sewer network, thus preventing the built-in odor traps from emptying. Once the vacuum is equalized, it immediately closes again to allow the sewer smell cannot escape from the system.
Does the air intake valve need to be maintained?
Yes, it is worth it sometimes, although at first glance it seems impossible to disassemble without damaging it, but for those who have already repaired something like this, it is a simple task. After disassembly, the small rubber membrane should be wiped with a soft dry cloth to avoid any deposits.
