I will tell you what information to use when dealing with "Afony" of our time. And competently force the plumbers from the housing department to eliminate the common reason for the ingress of unpleasant odors into your apartments.
The fetid odor of the sewer can enter apartments for several reasons:
- Fermentation of food residues in a kitchen siphon.
- The breakthrough of smells from the joints of the fan pipes into the room.
- Drying of the liquid in the water seal.
- Suction with discharged air waterblocking odors from the toilet and siphons.
To readers of the channel, earlier I talked about the first three reasons for the appearance of stench from riser pipes. Now I will tell you about the breakdown of the water seal due to the suction of water from squiggle toilets and a siphon. I recommend that you delve into the information so that "crawl" locksmiths in facts.
Breakdown of the water seal, the main reason
If you live in an apartment building and you have sewage odors, then the first thing to do is to look at two signs of malfunction:
Bubbling sounds from sink and sink siphons.
Swinging water (excitement), in the lower part of the toilet after the neighbors have drained the water.
If such signs are present, then the reason has been clarified. The picture below shows a normally working sewage system. Pay attention to the pipe with the signature ventilation, here all "salt" Problems.
Here's what can happen to this pipe, freeze or clog up.
Then the story looks like this: The head is frozen or clogged - Neighbor went to the toilet - water from the toilet like a piston creates a vacuum in the pipes because there is no communication with the atmosphere- due to vacuum, water is drawn out of the water seals - smells get into the apartment. Scroll through the gallery, I tried!
If you have odors for these reasons, then feel free to send locksmiths to the roof or attic to clear the connection of the fan pipe with the atmosphere.
