The smell from the sink in the kitchen: how to eliminate it yourself, instructions, photos and video tutorials

No matter how clean the hostess of the house is, and no matter how carefully she monitors the cleanliness of the kitchen sink, over time, the problem of the disgusting smell of the sewer will appear. What to do and how to deal with it? There are two ways out of the situation: to eliminate the unpleasant odor on your own, or to resort to the help of a specialist.

Do not leave dirty dishes in the sink for a long time. Grease and food waste clogs the siphon.

The causes of the smell

Sometimes the reason can be very simple, and the first thing every housewife resorts to when she stinks from the kitchen sink is to unscrew and clean the siphon. The fact is that over time, grease and dirt in the siphon accumulate, stick to the pipe walls, and decay processes begin. This is what causes the "sewage odors". But these are not all possible problems.

Do not dispose of food waste in the sink.

So, let's try to understand the main reasons for the unpleasant smell of sewage from your sink, in addition to the above. First of all, you need to understand the structure and functionality of the pipes running directly under the sink.

We all know what a siphon is. So in each siphon there must be a water seal or, so-called, water lock. After each water discharge, a certain amount of liquid is retained in the S-shaped part of the siphon. Water here plays the role of a kind of cork that traps odors from the drain and prevents them from spreading through the kitchen.

Regardless of which siphon you have installed, corrugated or flask (also called bottle), the principle of operation of both is absolutely the same - there must always be water, as a barrier to smell. Violation of this principle leads to the appearance of the appropriate "flavor", which will become a veil in your kitchen. So why does water stop stuck in the siphon?

And how to eliminate the disgusting odor?

1. Often, instead of a siphon, a corrugated pipe is installed, which tends to stretch and sag over time. Even if the installation of the corrugated pipe and its S-bend were made correctly, it will still lose its shape. In order to avoid this and postpone the replacement of pipes for a long time, it is necessary to fix the corrugation using special devices. They should be purchased along with the pipe. Another way: fix the pipe with special insulating tape.
2. The siphon was installed incorrectly. Often difficulties arise precisely with flask siphons. If the plastic pipe does not reach the water in the siphon flask, then an unpleasant smell is guaranteed, because the sewer stench will seep over the water lock. This misunderstanding can be corrected by adjusting the position of the nozzle. It should be immersed in water by 2-3 cm, but it is impossible for it to touch the bottom of the flask.
3. Also, a disgusting smell appears if the kitchen sink has not been used for a long time. If you have been absent from home for a long time, and upon returning you noticed that you smell from the kitchen sink, then most likely the problem is in the evaporated water from the siphon. In order to prevent this, you should drain a little sunflower oil into the drain before leaving. The oil forms a thin film on the water, which will delay the rapid evaporation of the water. Well, if you still forgot to do it or did not know about this option, then you just need to drain more water. After a while, the disgusting smell will disappear.
4. Probably one of the most common problems with a kitchen sink is fixing or even installing it yourself. If the corrugated pipe was not installed by an expert, it is likely that a "cost effective" installation was used. In this case, the water seal may be incorrectly formed, after which the water either rises back into the sink, or it is not delayed and goes into the sewer. There are also cases of stretching the corrugation and "sticking" it directly into the riser. Believe me, this is not worth doing.

Other causes of bad odor from the kitchen sink

Check the integrity of the pipes.

Sometimes the problem may lie not only in the siphon or its incorrect installation.

A disgusting smell can also appear due to the following reasons:

• Cracking or other mechanical damage to the drain pipe can also cause odors. The water seeps out and soaks the walls and floors, which eventually begin to grow moldy.
• Air venting of the riser. If the riser becomes very clogged, then when water passes through it, characteristic overtones are heard, after which a sewer stench appears. In this case, you will have to contact the housing office, because you can't do it with your own hands.
• Disappeared sealing between the sewer and the drain. In this case, you need to go through the joint again with the sealant. It is best to choose a silicone sealant.
