How to determine the return air draft from an apartment?
Greetings. I bought an apartment in a 10-story brick building on the 3rd floor. Immediately there were problems with ventilation.
The toilet smells from the neighbors, especially when they pour the waste mash into the toilet. I put a non-return valve from the film on the ventilation. The valve is constantly closed. The hood only starts when the balcony door is open. But the strangest thing is that with all the ventilation ducts closed, there is a strong draft in the hall. Craving goes inside the apartment, even into the keyhole. In winter, it pulls smoke in the cracks, it accumulates, which affects health.
Question: if there is cravings inside the apartment, then there should be cravings from the apartment. But I can’t find her. What could be the reason?

First, ask your neighbors on the site, how are they with ventilation? You have given a few introductory ... Do you have gas or an electric stove? Where does the craving for the hall come from? Take a strip of toilet paper and walk around the apartment. Find out where the greatest return thrust comes from, alternately opening the front and balcony doors.
One of the assumptions is that the chimney is clogged. It has not one exit, but several. One for the bathroom, another for the kitchen, a third for the column, if any. Bring a paper strip to each of the exits and determine if there is traction.
Tipping over traction is also possible. This is when the roof ridge is located above the chimney. The wind, blowing in a certain direction, causes such a phenomenon.
And, the easiest way out is to contact the management company.
Good afternoon. According to your description, the problem is only in the windows or slopes in the hall.
Possible reasons:
1. The windows are wooden, pulling due to cracks.
2. Plastic. Leaky shutter pressure, you can check by inserting a sheet of paper and pulling the window closed. Stretched out? Call the window-adjuster.
3. There may be a reason for the incorrect installation of the window sill, look under it with a lit candle, how the flame will behave.
4. If the apartment is renovated and the walls of drywall may be such a reason. You see a beautiful slope, and between it and the wall there is emptiness. The mounting foam in the window opening was not closed up and now there are through holes in the street (the foam collapsed over time). The problem drawing is indicated in the schematic drawing.
5. Slopes are not made on the street side.
I recommend breaking the drywall slope in the last turn, excluding other options.
It is advisable to install forced ventilation in the bathroom. To get acquainted with the nuances of this process will help this article is on our site.
Hello! In general, this problem should not be solved by you, but by the specialists of the management company, since you live in an apartment building. In theory, the ventilation system is not your property, it is common property, so if the simplest methods of fixing the problem did not help, you do not have the right to do something yourself, it will be called unauthorized reconstruction.
For you to be savvy with documents, this is regulated by Resolution of the Gosstroy of the Russian Federation No. 170 of 09/27/2003, paragraph 5.7.
Now, what needs to be done so that verification and elimination are accurately implemented. Call the dispatcher of the engineering department of your management company. It is advisable to include a call recording at this moment, but according to the law, be sure to notify the dispatcher about this. Fix the time of the call, name of the dispatcher. Explain the situation, leave a request to call specialists. You can also make it a personal visit and leave the application in writing, but always in 2 copies (you leave one to yourself).
Specialists are required to come and take the necessary measurements, inspection of the room to identify problems. Be sure to take a copy of the inspection and inspection report. Usually, such an act looks like in the photo attached by me, but may be slightly different.
If they did not help you, you can use the services of independent experts. They will do the following:
1. A request will be made to study the design documentation of the ducts for its exact compliance with all GOSTs.
2. Visually assess the quality of engineering equipment and its performance.
3. Take (most likely) air samples from the apartment.
4. They will try using technological equipment to look for possible causes of overlaps and blockages of ventilation ducts.
It should cost plus or minus about 3 thousand rubles, but this question should be clarified. In the end, not so much money when it comes to health. They will draw up a final inspection report. Make it either in 2 copies at once or then copy. By the way, experts will tell you according to the results of the check which norms and rules you should operate when communicating with the Criminal Code.
Here with these results, an act of inspection of the engineers of the Criminal Code and knowledge of regulatory documents, go to the head of your Criminal Code. Usually, when they see such a savvy person in front of them, and even with supporting papers, they begin to work efficiently.
If movement is not observed, draw up in writing, in 2 copies, a claim to the Criminal Code. They should give you a sample there on the spot. The claim is written in the name of the head. After the paper is on their table, certified by their seals and signatures (they must do this at the time of receiving the application), you wait 10 days. If you get a refusal, write a complaint to the supervisory authorities on your Criminal Code - Rospotrebnadzor, GZHI (state housing inspectorate), prosecutors.
Believe me, with all the documents on hand, you will win any court, if the fault is not yours, the reason will be eliminated, and you will receive compensation. But the Criminal Code very rarely brings to large-scale inspections and trials, most importantly, confidence at the stage of the first statement. This is all about examination and stuff - this is an extreme case, and it only looks intimidating. In fact, everything is not so troublesome.
