Causes of unpleasant odor from the kitchen sink

To understand what to do if kitchen sink smells like sewer, you need to find out why this problem occurs. You can eliminate the smell for a long time only after getting rid of the source of the stench.

• Often from the drain hole kitchen plumbing it smells unpleasant due to a breakdown or improper installation of the siphon - a drain element located under the sink and acting as a water barrier. In this case, foul-smelling gases from sewer pipes freely penetrate into the room. To prevent this, it is necessary to check the design of the siphon, eliminate possible breakdowns and replace parts that have become unusable.
• Sometimes the cause of the smell is the drying out of the water plug, which normally should always be present in the siphon flask. It acts as a barrier to unpleasant sewer “odors.” Most often this happens when the sink is not used for a long time. In this case, you just need to fill the siphon with water, and the smell will quickly disappear.
• The appearance of an unpleasant odor from the kitchen sink is often associated with clogged pipes. The main sign of this is the slow drainage of water. To remove stagnant mud masses, you need to use a plunger or a special flexible cable made of twisted wire, designed for cleaning plastic pipes.
• If there is a bad smell not from the drain, but under the sink, you need to check the pipes for leaks: cracks and other damage plumbing equipment lead to water leakage, causing the formation of mold and a corresponding unpleasant odor.
• Many sinks have an additional hole on the side wall to prevent overflow. Dirt, food debris and grease often accumulate in this area, which causes unpleasant odors. To eliminate the smell, you need to pour boiling water into this hole, which will wash away the deposits from the walls.

Eliminating stench with folk remedies

At home, you can use the following folk remedies for unpleasant odor from the washbasin:

1. Pour 100 g of baking soda into the drain hole and pour half a glass of vinegar, then plug the hole with a stopper or cloth and wait 5-10 minutes. After this, open the drain and pass through it a large number of water. This method of eliminating stench helps get rid of even strong bad odors and also helps remove blockages.
2. A mixture of baking soda and table salt will help disinfect the sink and remove odors coming from it. The components must be combined in equal proportions, poured into the drain and left for 20 minutes, and then rinsed the sink with a large volume of hot water.
3. To effectively remove sink odors, you can use citric acid. You need to take a large pack of the product, pour the substance into the drain hole and pour hot water. If the kitchen sink smells bad, instead citric acid You can also use freshly squeezed lemon juice.
4. You can get rid of smell from the sink using dry mustard. This powder dissolves dirt well and kills bacteria. The product must be poured into the drain hole and filled with plenty of hot water.

Each of these methods will quickly and effectively clean your sink. sewer smell without harm to the environment.

Household chemicals to eliminate odors

When folk remedies are powerless to combat the stench emanating from kitchen plumbing, housewives are looking for a way to remove the smell from the sink in the bathroom or kitchen using professional cleaning compounds.

These products work well to remove the “fragrance” from the sink. household chemicals, like “Mole”, “Domestos”, “Tiret”, “Sanox”.

It is best to choose cleaning agents in gel form, as they are able to penetrate much deeper into pipes than powdered ones. A thick gel product is poured into the sink, dissolves dirt and is washed off with plenty of water. The exposure time for such cleaning products can vary - from a few minutes to 12 hours.

When using chemical reagents, it is imperative to use rubber gloves and a respirator to protect the respiratory organs from burns.

Preventive measures

If your kitchen sink often stinks, it is important not only to take steps to eliminate the odor that has already appeared, but also to do everything possible to prevent the problem from occurring again.

Before washing dishes, it is necessary to remove any remaining food that may get into the drain hole and clog it. Also, do not throw small household and organic waste into the sink. After washing dishes, it is recommended to rinse the siphon with hot water for 20-30 seconds to wash away grease and food contaminants that have settled on it.

When installing a sink or siphon, you should trust the professionals to avoid installation errors. In addition, it is important to regularly check the condition of the pipes and correct any problems in a timely manner.

To prevent blockages and remove contaminants deposited on the walls of plumbing equipment, 1-2 times a week you need to clean the kitchen sink drain with citric acid, soda or vinegar.

Before leaving for a long time, pour a small amount into the sink vegetable oil: it forms a water plug on the surface protective film, which prevents the liquid from drying out in the siphon and prevents the appearance of an unpleasant odor.

Which method, in your opinion, is the most effective? Share in the comments, read all the reviews...

First, identify the causes of the problem:

1. Siphon clogged. The curved part of the pipe often stops functioning due to simple clogging with food debris, hairs, and greasy deposits. The particles settle in the siphon itself, on the surfaces of the pipes from the inside, forming a layer of sediment impenetrable to water. As they decompose, they emit a heavy rotting smell that spreads from the siphon through the sink into the kitchen.
2. Incorrect siphon installation. There is nothing complicated about connecting plumbing fixtures, but often the cause of spoiled indoor air is errors in pipe connections.
3. The siphon does not cope with its functions, the tightness is broken, air and pleasant smells enter the kitchen.
4. Hitting sewer risers air. The appearance of an air lock in the pipes will be indicated by gurgling sounds, as well as slow drainage of water.
5. Corrugation sagging. Even correct installed pipes stretch during use. Various problems arise: wastewater accumulates in the sagging area, and a water seal does not form.
6. Defects of pipes, corrugations, siphon. They arise due to mechanical impacts on the system, as well as due to the loss of corrugated elasticity.
7. Problems with sealing the corrugation and riser. All connections must be joined using rubber sealing rings, adapters, and adjusted to the diameters. If the installation is not correct, the smell will penetrate from the pipes into the premises.

Odor problems often arise when taps and sinks have not been used for a long time. There are no blockages in the siphon, but there is also no necessary protection from air and odors in the water. There must be water inside the device, creating a water seal. In the absence of water, pungent odors of sewage and rotting sediments arise.

Why is the smell dangerous?

Foul-smelling air is a big nuisance for household members. In addition to discomfort, it is dangerous due to toxicity. Components of heavy aroma:

• hydrogen sulfide;
• ammonia;
• methane.

The first two substances smell sharp and unpleasant, methane has practically no smell. The presence of these elements in the air negatively affects the state of the respiratory system and affects nervous system.

A person constantly feels discomfort, anxiety, and fear. Methane causes nervous breakdowns, sometimes – fainting.

How to remove smell from a sink using folk remedies

The problem should be resolved immediately. Helpers will help simple remedies Their main advantage is safety and lack of toxins.

Lemon acid

An assistant in many tasks in the kitchen is citric acid. To flush the pipe you will need 2-3 liters of boiling water and a pack of product.

1. The powder from the pack is carefully poured into the sink drain hole.
2. Slowly pour boiling water inside.
3. After some time, flush the pipe with clean water.

Soda

Regular baking soda works great for blockages in pipes. Procedure:

1. Pour baking soda into the drain.
2. Wait approximately 20-30 minutes.
3. Poured hot water.
4. Then the manipulations are repeated again.

If washing twice with soda does not help, choose a more effective option - soda and salt.

Soda and salt

First, prepare a combined composition by mixing soda and salt in equal proportions. All other stages are similar:

1. Pour the mixture into the drain.
2. They wait half an hour.
3. Pour boiling water over it and wait for the result.

Soda and vinegar

An “explosive” mixture for cleaning pipes under the sink is prepared using soda and ordinary table vinegar.

1. Pour a little soda (2-3 tablespoons) into the siphon through the drain.
2. Next, pour a glass of the bite after.
3. Close the drain with a stopper.
4. Leave for 10-15 minutes for the reaction to occur.
5. Rinse the sink with hot water.

Mustard powder

A similar method with mustard powder.

1. Pour 2-3 tablespoons of the product into the drain.
2. Wait 20-30 minutes.
3. Pour boiling water over the pipe.

Fixing the problem with a plunger

An irreplaceable thing in the household is a simple plumbing fixture, a plunger. It is advisable to have several plungers: for the toilet, sink, bathroom. The rubber cap of the device is applied to the sink drain and pressed with a handle. Turn on the water and then vigorously press the cap several times. Up-and-down suction streams of water pump the pipe, removing possible blockages.

The plunger is convenient to use if you do not want to disassemble the corrugation. Even women can easily cope with such a device. If the plunger does not help, use special cables.

Using a cable

Plumbing stores offer a wide range of different cables for cleaning pipes. Their length varies from 3-5 meters and more, while the cables are equipped with special handles for rotation, brushes or a spiral hook.

For the cleaning:

1. Remove the siphon corrugation.
2. Carefully insert the cable into the pipe.
3. They begin to push the device into the riser by turning the handle. The cable is screwed into the pipe, passing along its entire length.
4. Having tightened the blockage, they begin to move the cable in different directions. An alternative is to push the deposits further, hooking them with a hook.
5. Repeat the manipulations 2-3 times until the pipe is completely clean.
6. Connect the corrugation, turn on the water and rinse the pipe.

After use, the cable is washed to remove deposits and dirt and lubricated with oil. Place in a bay and store in a dry place.

Disassembling the siphon

Disassembly will help remove dirt and grease from the siphon plumbing unit. Corrugated tubes are considered self-cleaning; siphons with a flask require regular cleaning.

1. Place a basin or bucket under the sink and siphon.
2. Carefully unscrew the flask from the pipe, clean it, and rinse it. To remove greasy deposits inside, dishwashing gel is added to the water.
3. Reconnect the flask without losing the spacer rings in the connections.
4. Run water through the sink faucet, flushing the pipes.

Elimination of depressurization of joints

If the system sealing is damaged, you will need to use fum tape or special plumbing compounds. Types of sealants:

1. Compositions based on polyurethane. They have a sharp, specific odor. Required to use during operation personal protection.
2. Acrylic. Durable, shock-resistant sealants temperature regime. “Disadvantages”: low elasticity, which leads to depressurization of seams. Compositions of low and high moisture resistance are produced.
3. Silicone sealants. They do not shrink, are convenient and practical to use on all types of surfaces. The “minus” of silicone compounds is their high cost.
4. Combined sealants (silicone and acrylic). Plumbers use such compounds for sealing joints, as well as for gluing various materials.

Popular brands:

• CeresitCS7 (gives elastic seams);
• Tytan Power Flex;
• CIKIFIX (high adhesion to various surfaces);
• Moment Germent (suitable for wide seams);
• S 4000 (sealant with high mold resistance).

When working, first degrease the surfaces (with alcohol, acetone). Next, apply the composition with a spatula and level it, excluding tears.

Use of chemicals

Apply chemical compositions To eliminate the smell and clean the pipe, you need to be careful.

• Before purchasing and using, carefully read the instructions;
• take into account the specifics of the composition (alkaline remove fat deposits, acids act on blockages from hair, threads, soap).

Products are produced in the form of gels, powders, and liquids. Each case has its own method of application.

On a note!

Gels are considered the most economical. A small amount of the drug is enough to eliminate contamination and solve the problem of a clean pipe.

The list of the most popular drugs:

• Mole;
• Domestos;
• Mister Muscle;
• Tiret Turbo.

The drug Mole is effective - a liquid or powder that is affordable and copes well with all blockages in the system. Disadvantages: pungent odor, suitable for working with metal pipes.

Tiret Turbo quickly clears blockages and removes rotting odors from the sink. The series produces formulations of various concentrations:

• for complex blockages (red bottle);
• antibacterial (blue bottle);
• for prevention (green bottle).

Sanox gel is popular. Clean drain, safe for pipes made of any materials. In case of blockages, it helps little, but is indispensable for preventive flushing of water supply and sewerage systems.

Chirton, Baghi Pothan, and Selena granules do a good job with organic plugs. The first two preparations are based on caustic soda, which begins to work quickly when interacting with water. Disadvantage of the compositions: high cost.

From budget options Selenium granular preparation is popular, giving quick effect and does not have a pungent odor when used.

Preventing unpleasant odors from the sink

When solving the problem of a strong odor in the sink drain, do not forget about prevention. It is easier and cheaper to prevent a problem than to call plumbers and promptly clean the pipe.

Prevention rules:

1. Regularly clean drains and pipes in the kitchen, spilling them with special compounds.
2. Keep plumbing fixtures clean.
3. Use special grates and meshes in the sink to trap food debris.
4. When leaving home for a long time, pour a little sunflower oil into the sink to prevent water evaporation and drying out of the corrugation bends.
5. Use high-quality removable siphons in systems.
6. Periodically disassemble the siphons and clean the flasks and corrugations.

Conclusion

There are many ways to rid your apartment of unpleasant kitchen sink odors. After identifying the cause, use it to eliminate chemicals or folk recipes compositions. In the future, do not forget about preventive maintenance and keeping pipes and sinks clean.

The kitchen is the most frequently visited place in the house. Walking into this room, you want to feel the pleasant smells of baking or the freshness of detergents, but your expectations are immediately dashed by the unpleasant aroma that comes from the sink. Mixing with the smells of delicacies, it can cause even greater disgust, and staying in the kitchen becomes unbearable. In addition, the stench from the sewer can affect respiratory system humans due to the ammonia and hydrogen sulfide it contains. Questions arise: “How to get rid of the smell from the sink in the bathroom, in the kitchen? How to protect yourself from the action harmful substances? How to eliminate the cause of such discomfort?"

So, if there is a smell from the kitchen sink, how to eliminate it? The main ways to solve a problem come down to actions that can be performed without special knowledge, but some problems cannot be solved without a wizard. In any case, the house should have a plunger, special detergents, dry rags, plumbing strings. To begin with, if there is a smell from the sink in the kitchen (we’ll look at how to fix the problem later), you need to find out the reason for the unpleasant aroma.

Siphon contamination

Keeping the kitchen clean is an important task for the housewife, so the cleaning process often takes a lot of time. After a long cooking session or a family dinner, a whole mountain of dishes needs to be washed, and it is at this moment that a large amount of food debris ends up in the sink. Penetrating into the siphon, they begin to rot and thereby cause an unpleasant odor. So, having discovered that the siphon under the sink is clogged with rotting food debris, we quickly eliminate the smell from the kitchen sink by removing it and washing it. It is important to remember which part connects to which, so that after washing the siphon you can easily install everything back. You also need to wash it carefully so as not to break or spoil the parts. It would be good if there was a special tape in the house that would improve connections and serve as a replacement for seals for a short period of time.

Siphon contamination is one of the most common reasons from the sink. About 90% of housewives encounter it, and in all cases the problem is solved without difficulty.

Violation of tightness

At the junction of the siphon and the pipe, a leak is often observed. The occurrence of this problem is quite easy to determine (unlike blockages or internal breakdowns), since the result will be drips. If the problem has not been resolved at the time of its occurrence, these leaks cause a stench from the sink, the appearance of fungus and mold on the walls and floor. This happens when the seals are worn out or deteriorated. A temporary solution can be special or electrical tape, but new seals will help to finally solve the problem.

If a leak occurs between the pipes, then it is necessary to lubricate their joints silicone sealant.

Wastewater stagnation

Residues of food, hair, and fatty plugs can accumulate, making it difficult for water to pass through. As a result, the water gets retained, stagnates and causes a strong odor from the kitchen sink. How to fix it? The methods presented below are suitable for different cases and often give positive results.

The problem can be solved in two ways: rely on your own strength or call specialists. The second option is more reliable, but if you decide to do everything yourself, you need to use the means described below.

Plumbing cable

How to eliminate odor from the kitchen sink yourself? For this you need plumbing cable, which is sold in specialized stores. It is a steel spiral spring, usually with a handle, the main objective which - to hook and pull out debris from sewer pipes.

If you can’t purchase it, you can try to make it yourself. The cable must be slowly screwed into the pipe, thereby clearing the passage. This must be done carefully, as sudden actions can damage the pipe. It is better to involve another person who will help keep the cable taut.

Chemicals

If there is a smell from the kitchen sink, how can you eliminate it without using a cable? Exit - use chemicals. They are different types and are aimed at dissolving many contaminants: acidic agents work well with soap and hair, and alkaline ones work well with fat. In the store, it is better to clarify which of all those presented are best suited to combat your problems. They should be used according to the instructions and no more than once every two to three weeks. With frequent use chemical elements can damage sewer pipes from the inside. You should not use such products if the pipe is completely clogged: they can splash out, damage the surface of the sink, countertops, and also get on your skin or eyes.

To remove grease plugs in pipes (all types except plastic), you need to pour a large amount of boiling water into the sink. Used for plastic pipes warm water with washing powder diluted in it (100 grams of powder per 5 liters of water).

Folk remedies

You can also get rid of stagnant wastewater using traditional methods. To do this, you need to pour a few tablespoons of table salt or a hot solution of soda and water into the sink, and then rinse the drain thoroughly.

One such procedure is enough to get rid of small grease plugs or dirt, but for large blockages it will need to be repeated several times. Lemon or citric acid, which needs to be diluted with boiling water and poured into the sink in a slow stream, copes well with such problems. Another option is vinegar. After adding a few tablespoons of soda to a glass of vinegar, you need to pour the liquid into the drain and plug it with a rag to prevent the acrid vinegar smell from spreading throughout the kitchen.

You can get rid of small blockages in pipes using a plunger.

Violations of the installation of the sewer system

Trust the establishment of such complex system, like sewerage, should be done by highly qualified specialists, because in this case the possibility of problems arising is minimal. However, masters of their craft can also make mistakes, which results in an unpleasant smell in the kitchen. If due to installation errors sewer system There is a smell coming from the kitchen sink; only experts can tell you how to fix the problem. It is impossible to resolve this issue on your own without the necessary skills.

The sink hasn't been used for a while

When you open the door after a long vacation, business trip or other departure, you can hear a pungent smell from the kitchen sink. How to fix this problem and what causes it?

If the sink is left “idle” for a certain period of time, the water in the pipes begins to evaporate and an unpleasant odor fills the entire kitchen. In this case, you need to use an air freshener or any fragrance, that is, replace one smell with another, since the problem is not caused by damage and dirt.

Preventing unpleasant odors from the sink

Having found out where the smell from the kitchen sink came from and how to eliminate it, you need to think about actions that will prevent its occurrence in the future.

Cleaning drain pipes should be carried out not only in case of blockages, but also as a monthly preventive procedure. The use of salt, soda or citric acid can be frequent - up to twice a week. This will keep the pipes relatively clean.

Before you start washing dishes, you need to clear them of food debris, thereby preventing contamination of the siphon. Also, you should not pour tea leaves into the sink, throw away small garbage, clean a comb over it, etc.

When leaving for a long time, you need to prevent a fetid odor from appearing in the entire kitchen by pouring about 100 grams of machine or vegetable oil into the sink. It will create a film that will significantly slow down the evaporation of water from the pipes. Upon arrival, you must use a cleaning agent and rinse the system with warm water.

Questions regarding the replacement of some parts of the sewer system, its modernization and repair should be entrusted to specialists who, using professional tools and the necessary skills will not harm her. You should not rely on a friend or neighbor in such a situation.

When purchasing new elements, such as a siphon, it is important to take the advice of experts or consultants, focus on quality and ease of use, and not on price.

To remove fatty contaminants in the siphon, it should be rinsed after each dishwashing in hot water for 20-30 seconds. This will extend the service life and partially prevent grease from getting into the pipes.

Extraneous unpleasant odors in the kitchen make few people happy. Especially if there is an odor coming from the sink. After all, it is impossible to get rid of it by simply spraying an air freshener. The most annoying thing is that an unpleasant smell in the kitchen from pipes can appear even in the cleanest houses, where cleaning is done constantly. Why does this smell appear from the sewer and how to get rid of it?

Unfortunately, there can be many reasons. The first and simplest is a clogged siphon. Residues of food and fat gradually settle on its walls. All organic products tend to rot and release a characteristic odor. Hence the notorious smell from the pipes. This cause can be eliminated by removing and washing the siphon.

Other causes of odors:

• incorrect design of the siphon and disruption of its operation;
• the sink has not been used for a long time;
• damage to the drain pipe;
• lack of sealing of the sewerage system from drainage;
• air in the riser.

If the drain is damaged, water saturates everything and a characteristic moldy smell appears from the pipes. It can be eliminated only by eliminating the breakdown.

A clogged riser leads to the formation of air jams. Draining water causes an unpleasant smell from the pipes.

Solutions

Before you get rid of the smell, you need to clearly find the cause of the smell from the sewer. After this, the cause must be eliminated.

Clogged riser and air lock

You can remove the blockage in two ways - on your own and by specialists - plumbers from the housing office. The second way is more preferable, since it requires special equipment and experience.

But if the house has a long metal cable and a little courage, you can try to get rid of the blockage yourself by carefully screwing the cable into the pipes and clearing the passage.

Pros:

• you can save money;
• The result lasts longer.

Minuses:

• If done incorrectly, the pipes can be damaged.

Lack of sewer sealing

If the smell from the sink is due to the fact that the joint between the drain and the sewer pipe has become depressurized, then eliminating it is very simple - just take silicone sealant and coat the pipe joints with it.

Violations of the siphon design

The siphon has a water lock or, in scientific terms, a water seal. It is necessary to ensure that not all water leaves the siphon. The water in it acts as a plug and delays the spread of odor from the sewer pipes to the outside. If the water in the siphon does not linger, the smell in the kitchen will not be long in coming. This happens if the siphon is installed incorrectly or the corrugated pipe. If the corrugation simply sagged and stretched, then it can be fixed with electrical tape or special devices.

If the siphon is installed incorrectly and the pipe does not reach the water, you need to adjust its location by submerging it a few centimeters.

Important : The pipe must not fall to the bottom of the siphon.

No operation

When you are away from the house for a long time, the water in the drains also dries up and a characteristic smell appears from the sink, which has not been used for a long time. To prevent this from happening, you need to add it to the drain before leaving. sunflower oil. Water will not evaporate through the oil film and no smell will appear.

Chemicals

You can also get rid of odors using chemicals. This method is suitable if the cause of odors is the accumulation of fat residues and other organic substances in the drain and siphon.

Important: You can use the traditional method. To do this, pour regular table salt or a mixture of soda and water into the drain. The mixture should be very hot. After a while, you need to open the water and thoroughly pour the drain, rinsing it. The smell will disappear.

Prevention

So what needs to be done To eliminate odor from the start:

• use mesh to protect the drain from food debris;
• periodic use of household chemicals - you can pour Fairy into the sink once a week and flush the water - this will dissolve fat deposits;
• Every day, after each washing of dishes, you need to run hot water into the sink for a few minutes - it dissolves grease and removes it from the walls.

conclusions

Getting rid of foreign odors from pipes is quite simple. The main thing is to find the cause and eliminate it.

Smell from pipes in the kitchen: 3 main causes and methods for eliminating them

Don't know how to get rid of the unpleasant smell coming from the sewer pipes in the kitchen? The experience I have accumulated allows me to say that it is not at all necessary to call a plumber for this; in most cases, the problem can be dealt with on your own. Let's look at them in more detail.

We find the cause and eliminate it

Why might my sink start to smell? As a result:

1. Pipe blockages;
2. Depressurization of the pipeline body;
3. Malfunction of the water seal.

Let's look at everything in order:

Reason #1: clogged pipes

The most common cause of foul-smelling fumes from a sink is the accumulation of grease, food debris and other debris in the pipeline that interferes with free movement. Wastewater. We are not talking about the formation of a complete jam, since in this situation the problems will be much more serious than some odors.

But also some reduction in diameter sewer pipe enough to make staying indoors problematic without a gas mask. In this case, the following methods will help eliminate odor from the kitchen sink:

Before you start cleaning the pipes themselves, I recommend first disassembling and removing all accumulated debris from the siphon. It is likely that the source of the stench is in it, and not in the pipeline.

Photo	Description
	Home Remedies. The price of such a solution to the problem is relatively low, since you can most likely find everything you need right there in the kitchen: Let's fall asleep with your own hands, soda and salt into the drain hole; Fill in boiling water The poured solution will corrode fatty deposits and restore normal water flow in the sink. The volume of ingredients can be changed depending on the severity of the problem: A glass of soda, a glass of salt and a kettle of boiling water for periodic maintenance of the pipeline; A pack of soda, a pack of salt and 2 liters of boiling water if an unpleasant odor has already appeared.
	Household chemicals. This option will be a little more expensive, but it will be more effective in case of significant accumulation of waste in the pipes and will be able to quickly eliminate the smell of sewerage. Tools such as: Mole; Tiret; Pipe Cleaner; Sterilized; Pothan; Deboucher.
	plunger. Appearance resembles a large suction cup on a wooden or plastic handle. Helps get rid of even serious garbage jams. Instructions for use: Dial water into the sink; Attach a plunger with a suction cup to the drain hole; Do several progressive movements down and up; Sharp remove the tool, allowing the flow of water to complete cleaning of the pipeline.

Before using household chemicals, I recommend wearing rubber gloves and opening the window. For large volumes, you should even use a respirator. The fact is that direct contact with cleaning substances and their evaporation can harm a person.

Reason No. 2: depressurization of the pipeline body

If odors come from under the sink, then the matter is not a clogged pipeline, but a violation of its tightness. Several situations are also possible here:

Photo	Description
	Deformation threaded connection in the siphon or the appearance of a crack in it. Both situations are a consequence of the fact that the installed hydraulic device cannot cope with the volumes of liquid that enter it. Therefore, there is no point in trying to repair it; it is better to immediately change it to a more voluminous model.
	Deformation sealing ring at the junction of the waste pipe and the socket. What to do in this case? There are three possible solutions to the problem: Dismantling connections and replacement of the o-ring; Sealing joints with silicone sealant, if we are talking about plastic pipes; Sealing connection points with a rubber band, if we are talking about cast iron pipes.
	Crack in the pipeline. Here you shouldn’t rely on silicone; only a rubber band or clamp with similar properties will help.

Reason No. 3: malfunction of the water seal

The water seal is formed by a siphon or a curved pipe made of corrugated plastic or stainless steel. It is a permanent water plug, which prevents sewer odors from entering the kitchen. If the water level in it drops, then everything unpleasant aromas enter the room.

Let's consider situations in which a malfunction of the water lock may occur:

• Corrugated pipe bent. We return it to the desired position, fixing it with tape;
• Small diameter in the riser or poor ventilation in the sewer. In these cases, it is better to immediately call a plumber; you may not be able to do it yourself;
• The water has evaporated due to a long period of inactivity.. Just start using the sink again.

If you are leaving home for a long time and do not want unpleasant odors to spread throughout the rooms during your absence, add to the water seal machine oil. It will significantly slow down the evaporation process.
