How to remove an unpleasant smell from the kitchen sink? How to eliminate odor from a kitchen sink: the best methods, identifying the causes. Sink smells, how to remove the smell

Every home has its own characteristic smell. But the room does not always smell of pleasant detergents, refreshments or flowers. It's not very good when bad smell from kitchen sink spreads throughout the apartment. Perhaps it is simply clogged and needs cleaning. Many housewives do not know how to eliminate odor from the kitchen sink, so we will look at the reasons for its appearance and what to do about it.

The main reason why there is an unpleasant smell in the kitchen is sewerage problems. The main function of washing is to remove different types mud. The drain installed under the sink is directed to the sewer pipes.

The causes of sewer system malfunction may include the following:

siphon clogged. A siphon is a small curved part of a waste pipe. Its role is in maintaining the water level inside the bend, as well as separating the air in the room and the sewer pipe. Over time, inside the pipe, siphon due to poor care A greasy coating may form. Small particles of food waste stick to it;
airing of the sewer riser. This malfunction is indicated by a characteristic gurgling sound inside the sink. In this case, only a housing office employee can fix the malfunction, because this is a malfunction of the main system;
mechanical damage to the drain pipe;
pollution inner surface pipes through fats, food residues;
deformation corrugated pipe. Over time, the corrugation has the ability to stretch and sag. Such situations happen even with proper installation. Due to the stretching of the corrugation, water is unable to be retained and is drained directly into the sewer. In addition, it can return back;
violation of the seal between such parts of the sewer system as the riser and drain. This is a mistake made by sewer system installers. Quite often they don't worry about sealing and just insert the corrugated pipe into the riser hole;
evaporation of moisture from the valve due to non-use of washing, location heating pipes under the shutter. If the sink is rarely used, the water evaporates from the water seal, which is formed in the bend of the siphon and prevents the spread of sewer odor;
installation flaws (workers may choose the wrong pipe diameter).

Types of siphons different types and the principle of their operation

In addition to the main reasons for the appearance of stench from the sink, you need to take into account more rare provocateurs of unpleasant odors in the kitchen:

severe wear, cracking plastic pipes wires;
siphon malfunction;
improper design of the drainage system at the bottom of the sink;
holes on metal pipes sewerage.

Why is the smell from the sink dangerous?

The stench from the kitchen sink is not only a nuisance for the housewife, but also a danger to the health of the apartment residents. Humans are able to recognize odors, which is considered a natural mechanism necessary for survival. The body defines an odor as “disgusting” only in situations where the stench can harm it.

The air that enters the premises from the sewer system contains toxic gases:

hydrogen sulfide;
ammonia.

These components explain the unpleasant smell from the sink. Sewage air also contains methane. It is formed due to the decomposition of sewage. This gas does not have any odor, but it still remains dangerous. Long-term effects of toxic gases on the body threaten negative consequences.

The smell from the sink is not only unpleasant, but also dangerous.

Important: Methane, ammonia, and hydrogen sulfide harm the respiratory system and can cause partial loss of smell. When exposed to foul odors nervous system, there is a feeling of increased anxiety. Sometimes they provoke nervous breakdowns and fainting.

Considering the above facts, it is better to fix the problem with unpleasant smell than to harm yourself and your loved ones.

Effective ways to eliminate sink odor

You can remove odor from your kitchen sink in different ways, which are offered by specialists.

Removing blockage with a cable. When kitchen waste or toothpicks get into the sewer, grease and food remains are retained and a plug is formed, reducing throughput pipes The adhesion of fat and food provokes a putrid odor. A metal cable will help remove the plug. It should be firmly grasped with your palm, slowly rotated and pushed further. The plug can be pushed further along the pipe or removed from the sewer (in the case when the cable is equipped with a hook at the end). If the blockage is removed, the water flow returns to normal. Water must first be supplied in a thin stream, then you can open the tap harder. This is necessary to ensure that the blockage is cleared. It is recommended to turn on hot water. It helps get rid of greasy deposits and plug residues from the pipe walls.

After cleaning the system, the special cable for cleaning the sewer should be washed, wiped, and lubricated with machine oil. These actions will prevent rust from appearing on the product. The dry cable needs to be rolled up and stored.

Using a cable to break through blockages

Using a plunger to clean. It is necessary to inspect the siphon. If the problem is caused by stretching of the corrugation, incorrect installation design, it is enough to install everything correctly and fix it. If the stench is caused by a blockage, clean the siphon and drain with a plunger. It must be new, which has not been used to clean the bathtub or toilet.

The drain hole of the washbasin is covered with a plunger cap, pressed, then the tap is opened with hot water. After the cap is closed with water, you need to press firmly on the handle of the device several times. This is necessary to pump water up and down and break the plug that has formed in the pipe. Then the plunger is removed to wash away the remaining clog with water.

Disassembling, washing the siphon. Before starting this action, you should place a bucket under the sink. This is necessary to prevent water from pouring out of the water seal onto the floor. Then we unscrew it wrench or use a settling cup with your hands. If you have a non-separable structure installed, then you need to remove the entire siphon. After all the water has drained, we begin cleaning.

The pipe located behind the siphon is checked and cleaned if necessary. The siphon itself is washed with household chemicals(dishwashing detergent, dissolved powder, washing gel). After such cleaning, the siphon is assembled, the tightness of the connections and the position of the entire structure are checked.

Methods to help clear a small blockage in the siphon

Sealing joints. When the smell is caused by depressurization of the joint between the drain and the sewer pipe, it requires sealing. The simplest method is to wrap it with fum tape, but a better method is to use a special plumbing sealant (“Moment”, “Tytan”, “Ciki Fix”, “Ceresit”). It will prevent the appearance of mold, mildew, and the proliferation of microorganisms.

To prepare the surface for applying sealant, you need to use acetone, alcohol, and a dry soft rag. Apply the sealant using a soft narrow spatula. The joints should initially be wiped dry and degreased. Then the sealant is squeezed out so that it covers the entire joint in one strip (without breaks). A spatula is used to smooth the seams.

Sealants for sewer pipe joints

Protecting the water seal from drying out. To do this, just open the tap more often, replenishing the water level in the siphon.

Disinfection with soda and salt. These folk remedies are considered good disinfectants that will help remove bad odors from the sewer. To do this, you need to pour it inside the sink drain hole, let it sit for 20 minutes, then rinse the sink with plenty of water. This method can also be used for prevention.

For flushing out simple clogs you can use baking soda + vinegar. Inside sewer drain pour out half a pack of soda, pour vinegar into this mass, and plug the hole with a rag. The sewer must be flushed after 20 minutes.

Note: To improve the smell of the room, you can add flavored oil (mint, lemon, rose, lavender, etc.) to the mixture. Thanks to this simple method, the room will smell nice.

You can also apply citric acid. A large pack of powder is poured inside the drain hole and poured with boiling water. Such products will help eliminate unwanted odors from the kitchen sink at home.

Products for removing odor from pipes

Washing with special means. There are many different household chemicals that are produced for cleaning drains. Its purpose is to eliminate plaque on pipes, dissolve blockages, disinfection, and eliminate unpleasant odors. Very popular and effective remedies are “Mole”, “Mr. Muscle”, “Floop”, “Pothan”, “Tiret”.

Products for removing blockages and prevention

We have already looked at how to remove the smell from the sink if it appears in the kitchen. Now we will give you ways that will prevent the appearance of stench from the sink:

Do not clean off food residues in the sink;
for prevention, pour soda + vinegar into the pipes once a week;
Use personal protective equipment when cleaning chemical pipes. means (gloves, glasses, bandage);
Rinse with hot water every time you wash dishes. drain hole;
If you are away from home for a long time, pour into the sink a product that prevents the evaporation of water in the bend (sunflower or other oil). This ideal option for a summer residence;
install a removable siphon;
ventilate the room if you use “Mole” and its analogues;
Do not use aggressive chlorine cleaners for metal sinks.

If there is a stench from the kitchen sink, you already know what to do and therefore, in most cases, you will be able to cope with the problem yourself. You shouldn’t endure the unpleasant and quite dangerous smell sewers in a place where the whole family gathers, and the housewife spends most of the day preparing everyone's favorite dishes.

The problem of unpleasant odors in the kitchen should be eliminated, not ignored

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:

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

Let's look at everything in order:

Reason #1: clogged pipes

Leftover food thrown from the plate into the sink quickly clogs the sewer system

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 the free movement of 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.

Impassable congestion is a more serious problem than the appearance of unpleasant 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.

Sometimes, to rid the kitchen of sewer odors, it is enough to rinse the siphon, which actually needs to be done regularly

	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 sewage. 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.

Rubber gloves will protect the skin of your hands from harmful effects household chemicals

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:

Reason No. 3: malfunction of the water seal

The water seal forms a siphon or curved pipe, made of corrugation, 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 all the unpleasant aromas enter the room.

The principle of water seals is very simple and reliable

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 machine oil to the water seal. It will significantly slow down the evaporation process.

Conclusion

You have learned how to get rid of unpleasant smells from pipes in the kitchen. The video in this article contains additional materials. You can ask questions in the comments.

The most common cause of foul odors coming from the sink is a clogged sewer line.

Smell from the pipes?

The smell from the pipes in the bathroom or kitchen is a problem with a very unpleasant odor. It occurs mainly when the pipeline and its elements are severely worn out and need to be replaced. In some cases, the cause is the condition of the drains throughout the house. Naturally, you are unlikely to be able to solve this problem alone. However, if the reason is the deplorable condition of the pipes in your apartment, or blockages in them, you can eliminate the smell yourself.

What should you do first?

If the smell appears in the bathroom or kitchen, inspect the pipes before trying to get rid of it. There should be no deformation on them. The joints should be checked for integrity. If there is damage, it is quite possible that this is the cause of the problem. In this case, you will have to change or reinstall the structure. Temporary methods, such as cleaning pipes, cannot be done here.

If water flows into the drain with specific gurgling and other sounds, it is quite possible that the water seal in the system has been broken. Also check the condition of the siphon. Its short partition can cause the water seal to break. In order to get rid of the smell, in this case, it is enough to replace the siphon.

If you have a corrugated pipe in your kitchen or bathroom, inspect that too. If it has lost its former appearance, you can give it the desired

Chemical cleaning

form, twisting and sealing with electrical tape. However, ideally, it should be replaced with a new one.

Simple ways to eliminate odor

If the problem is caused by a clog, you just need to clean the pipes to solve it. Various chemicals are used for this purpose. For example, “Mole”, “Domestos”, “Mr. Muscle” and others. In order to get rid of the smell, you can use traditional methods:

Table salt is poured into the pipeline. Then, after waiting a little, it is washed off with running water;
Washing soda (2 tablespoons) is poured with a liter of boiling water. Then the composition is poured into the drain hole;
Soda is poured into the drain. Following this, acetic acid is poured in. The drain hole should be tightly closed. After half an hour, the drain opens and the water is turned on to rinse off the composition;
Prepare a mixture of washing soda and salt. Then it is poured into the drain hole. Salt helps get rid of amber, and washing soda allows you to clean the pipeline.

Tiret to help.

To ensure that the smell from pipes in the kitchen and bathroom does not bother you in the future, it is recommended to apply the above preventive measures once a week. For this purpose, preventive chemicals can be used. There are also temporary ways to eliminate odor from pipes:

The zest of an orange or lemon is set on fire indoors. A small piece is enough. It is important to follow all safety measures;
The bathroom should be ventilated after each “bath procedure”. Constantly closed door only exacerbates the problem;
Until a solution to the problem is found, you can use air fresheners.

If the design is completely intact, the cause of the problem may be evaporation of liquid in the water seal caused by infrequent use of the taps;
If you are going on a long-distance train, fill the waterproofer with oil. This way you will prevent drying out in the system;
Buy a special siphon. It will be a kind of barrier for amber;
Replace the gaskets in the pipeline.

What to do if you have already tried many methods, but the unpleasant smell from the pipes remains? In this case, it makes no sense to buy more and more new chemicals, look for traditional methods fight against amber. Most likely, the cause of the problem is more serious than you think, and ordinary means will not get rid of it. In this case, do not overuse air fresheners. Better try to replace the system quickly if this is the cause, or take an interest in the general condition of the sewer system in your home. In the latter case, you should contact the appropriate services for help.

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 the human respiratory system due to the ammonia and hydrogen sulfide it contains. Questions arise: “How to get rid of the smell from the sink in the bathroom or kitchen? How to protect yourself from 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, and 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’s good if there is a special tape in the house that will improve connections and serve as a replacement for seals for a short period of time.

Siphon contamination is one of the most common reasons unpleasant smell 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 a special sealing tape or electrical tape, but new seals will help to finally solve the problem.

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

Wastewater stagnation

Food debris, hair, and grease plugs can accumulate in sewer pipes, 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? To do this you need a plumbing cable, which is sold in specialized stores. It is a steel coil spring, usually with a handle, whose main purpose is to hook and pull debris out of 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? The solution is to use chemicals. They come in different types and are aimed at dissolving many contaminants: acidic products 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. For plastic pipes, warm water with diluted washing powder(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 spoons into the sink. table salt or a hot solution of soda and water, 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 lemon copes well with such problems. citric acid, which needs to be diluted with boiling water and poured into the sink in a slow stream. 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 errors in the installation of the sewer system, a smell appears from the kitchen sink, only specialists will 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. 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 it. 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.

It would seem that constantly maintaining order in the kitchen or bathroom is the key to freshness and cleanliness. However, regardless of the degree of neatness of the housewife, sometimes kitchen air it doesn’t smell like fragrant baked goods, and the smell in the bathroom is reminiscent not of the freshness of a sea breeze, but of ominous footage from horror films.

Let's take a look how to get rid of smell from sink, and at the same time check the serviceability of the sewer drain.

Checking the serviceability of plumbing fixtures

The very first thing to do when an unpleasant odor appears from the sink or bathroom is to disassemble and clean the siphon. Very often, it is the dirt accumulated in this device, consisting of food residues or grease, that stinks. Sometimes the siphon may burst due to sudden changes in the temperature of the hot and cold water. In this case, you can try to solder it using a hair dryer and a piece of plastic, or glue it epoxy glue and fiberglass. But it is better to replace this part to be completely sure of its serviceability.

Often the cause of an unpleasant odor lies in a faulty siphon.

In addition to problems with the siphon, there are a lot of other possible reasons for the appearance of unpleasant odors in the kitchen and bathroom, namely:

Clogged sewer;
Leakage of water from water seals;
Cracks in pipes or loose joints;
Poor adjustment of sewer riser revisions.

To eliminate the causes of the malfunction, the defective location is first localized and then repaired.

Clogged drain pipes

If a blockage appears in the drain line, it must be removed. To do this, you can use a plunger after drawing a small amount of water into the sink. A vacuum cleaner can be used for the same purpose by setting its hose to blow out and then connecting it to the drain pipe. It is only necessary to first seal the connection point.

A plumbing cable can help remove severe blockages.

To remove more severe blockages, use a plumbing cable. Rotate this device and periodically turn on the water supply. This will help you deal with it faster clogged sewer. In the case of plastic pipes, this method should be used very carefully.

If plumbing cable no, then a long thin hose can correct the situation. It is inserted into the pipe, and then the entry point of the hose is blocked and water is released. Under the influence of water pressure, the blockage is gradually washed away. Additionally, it is necessary to disassemble and wash the siphon.

Often the cause of the smell is an improperly installed siphon. When assembling it, pay attention to the location of the plastic pipe. It should not reach the bottom of the flask and at the same time be 2-3 cm in the water.

Lack of water in the water seal

To prevent odors from the sewer system from penetrating into the house, water seals are installed at all drain holes, which in the simplest case are a U-shaped elbow filled with water. It is the liquid that prevents the spread of stench. Water from the water seal may evaporate if the tap is rarely opened.

Also, the lack of fluid may indicate a failure of the water seal. This is what is called suction of water into the riser. This is possible in case of malfunctions in the ventilation of the sewer system, which occurs when foreign objects enter the riser, as well as when it freezes in winter. To make sure that the main sewer pipe is properly ventilated, you need to go up to the roof and inspect it.

The water seal prevents the penetration of odors from the sewer

A broken water seal is indicated by hissing or squelching sounds coming from the sink as water flows out, so to detect this malfunction, listen to the sounds coming from the drain hole.

Often a water seal is installed by installing a bend in a corrugated pipe instead of a siphon. Over time, this pipe can sag, thereby contributing to failure. To avoid this phenomenon, secure the bend with wire or insulating tape.

In case of a long absence, before leaving, you can pour a little machine oil into the siphon to eliminate evaporation of the water seal.

Elimination defects pipeline

Cracks, crevices and leaking joints are common in older sewer systems. To eliminate them, use various ways. Small cracks in straight sections of pipelines are repaired by applying bandages or sealing clamps. Large holes are sealed using patches and epoxy resin. Leaks in pipe connections are eliminated using tarred asbestos cord packing.

In some cases, the cause of an unpleasant odor may be depressurization of the junction of the drain and sewer pipes. It is necessary to carefully inspect the connection point and, if necessary, eliminate leaks using silicone sealant.

When examining the drain pipeline and riser, pay special attention to the tightness of the inspection hatches of the risers.

Methods for eliminating unpleasant odors

Using household chemicals

Modern industry produces a variety of chemicals designed both to clear even the most severe blockages and to remove the unpleasant odor coming from the drain hole. Such drugs come in both liquid and gel form, and even in the form of granules.

Used for cleaning sewer pipes chemicals, containing caustic soda, so handle them carefully and carry out all work with rubber gloves.

Chemicals used to remove blockages and unpleasant odors from drain pipes

Good results are obtained by using the compositions “Mole”, “Brawler”, “Odorgon”, as well as “Domestos”, “San Clean”, “Tiret” and others. These products are poured into the drain and left for a certain time (usually 2-4 hours), which is indicated on the packaging. The drain is then washed with a large amount warm water.

If the drain in your apartment is made of plastic pipes, use the Israeli product “Pothan”. These granules are suitable not only for metal pipelines, but also do not destroy plastic products.

Good results can be obtained by using household chemicals that contain chlorine. For example, you can use “Whiteness” or dry bleach powder. The use of such substances will also save your finances. Even greater savings can be achieved by knowing one secret. Namely, all of the above preparations are based on the action of soda ash, so you should always have a package of this substance on hand.

Buying chemicals cleaning, pay attention to the possibility of using them for plastic pipes, if such a drain has been installed in your home.

Traditional methods

If you don't have special chemicals on hand to clean your drain, don't worry. The compositions discussed below can be prepared in any kitchen.

To eliminate sink odors, stir three tablespoons of regular baking soda in 1 liter of warm water. Then this solution is poured into the drain hole and left for at least 30 minutes. After this, rinse the drain with hot water. Instead of soda, you can use table salt.

When flushing the drain with hot water, take into account the material of the sewer pipes. If you use plastic products, the line can be damaged by boiling water.

Table vinegar or solution is used in the same way. acetic acid. Pour at least 0.5 liters of liquid into the drain and wait 20-30 minutes. Then the pipeline is washed with warm water.

Simple drain cleaners can be found in any kitchen.

Often, to remove unpleasant odors, both soda and vinegar are used simultaneously in a 1:1 ratio. First they fill the hole baking soda and then pour vinegar.

Dry mustard powder, which is poured into the drain and then poured boiling water over it, also gives a good effect. However, this method is not suitable for plastic pipes.

There is no need to treat this with irony traditional methods. The fact is that any unpleasant smell from the sewer is the result of the activity of bacterial colonies. When these bacteria are eliminated, the stench goes away. You can fight them with any alkalis or acids, even if it’s ordinary soda and vinegar. Plus, by using these substances instead of “real” chemicals, you save the environment.

Preventing blockages is the key to avoiding unpleasant odors.

Prevention

In order not to wait for the drain to deteriorate and an unpleasant sewer smell to appear in your kitchen and bathroom, make it a rule to flush the drain once every two weeks with hot water and any detergent. Once a month it is necessary to disassemble and clean the siphon, and every six months carry out preventive maintenance for the pipes using caustic soda or any special cleaner. And then your kitchen will smell only of fragrant pies and hot tea, and a fresh sea breeze will blow in your bathroom again.

Many housewives are faced with the task of getting rid of various unpleasant odors in their homes. Common everyday problem there is a bad smell from the kitchen sink, and not everyone knows how to eliminate it. Folk methods and proven store-bought remedies will help you get rid of the stench.

Causes of unpleasant odor from the kitchen sink

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

Often, kitchen plumbing drains smell unpleasant due to breakage or incorrect installation siphon - a drain element located under the sink and performing the function of a hydraulic 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 to the plumbing equipment lead to water leaks, 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:

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 pour a large amount of water through it. This method of eliminating stench helps get rid of even strong bad odors and also helps remove blockages.
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.
To effectively remove sink odors, you can use citric acid. Need to take big pack product, pour the substance into the drain hole and fill it with hot water. If your kitchen sink smells bad, you can also use freshly squeezed lemon juice instead of citric acid.
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 the sink from sewer odor without harming the pipes 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.

The “fragrance” from the sink is well removed by such household chemicals as “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.

Housewives put a lot of work into getting a comfortable cozy atmosphere in the apartment. Special attention is given to the kitchen, because this is where food is prepared and dishes are cleaned of dirt. Unpleasant odors often appear in this room, which gradually spread throughout the apartment. One of the reasons for this unpleasant phenomenon is considered to be a blockage in sewer system. In our article we will learn how to eliminate odor from the kitchen sink, consider the causes of its occurrence and methods of combating it.

Reasons

Before choosing a specific method for eliminating an unpleasant odor, you need to understand the cause of its occurrence:

Formation of blockage in the siphon. When washing dishes, grease, cereals, vegetable peelings and food waste enter the sewer system. Over time, these substances accumulate on the walls of the pipes or in the siphon and form plugs. Rotting deposits create an unpleasant odor, which can only be removed by thoroughly cleaning the siphon.
The second popular reason is inconsistent use of the sink. A water seal does not form in the siphon, which should prevent the penetration of foreign odors from the sewer system. If plumbing for a long time was not used for its intended purpose, the liquid will evaporate and the smell will penetrate the room.
Incorrect siphon installation.
Corrugation deformation during operation. Over time, the tube changes its initial location and may sag or stretch. In this situation, a blockage occurs or the liquid completely drains into the sewer, which prevents the formation of a water seal in the siphon.
Lack of sealing at the junction of the riser and pipes. The corrugation is simply stuck into the drain hole after the siphon, its second end is inserted into the sewer.
Airing is accompanied by a characteristic gurgling sound from the sink. This phenomenon often occurs when neighbors above have installed plugs on sewer inlets.

As we can see, unpleasant odors in the kitchen can appear for various reasons. Next, we’ll find out how to get rid of smell from the sink.

Relevance of the issue

The smell from the sink is not only unpleasant, substances entering the premises can affect human health. The air entering the room from the sewer system contains harmful gases (ammonia, hydrogen sulfide and methane). The latter substance is especially dangerous; it is impossible to notice its presence, because methane does not emit an odor.

Prolonged exposure to harmful fumes leads to loss of smell and affects the respiratory organs. These gases also affect the nervous system. A person develops a feeling of anxiety, which can lead to nervous breakdowns.

A plumber will help you diagnose sanitary equipment, but you will have to wait a long time for a specialist and then pay for the services. This option is recommended for use in case of serious damage; most of the work can be done independently without special skills.

First you need to monitor the operation of the sink. If the liquid drains normally, but the smell does not disappear, wash the pipe with hot water and detergent or a solution of vinegar and baking soda. If such operations fail desired result, you will have to inspect the pipes and siphon for cracks and leaking connections. Perhaps in engineering communications there is a leak. If moisture is detected, the joints are sealed with sealant or wrapped with foam tape.

Methods to combat unpleasant odors

Before you eliminate sewer smell in the kitchen, you need to understand the cause of its occurrence. If all connections of sanitary fixtures are sealed, then an unpleasant aroma enters the room through the formation of blockages in the pipes. There are several methods for destroying traffic jams; let’s look at them in more detail.

Cleaning cable

A standard steel cable will not solve the problem; to destroy the plug, you need to use a special product with a hook and a brush. Its length ranges from 3-5 meters; a handle is installed at the end for performing rotational movements.

To remove a blockage in the sewer, you must take the following steps:

Remove the corrugation from the inlet to the sewer system.
Insert the cable into the pipe and begin to push it to the maximum depth.
We rotate the handle and at the same time hold the casing.
Similar manipulations are carried out until the cable comes into contact with the blockage. Next, you can try to destroy the cork or pull it out using a hook.

After the procedures, the instrument is thoroughly washed, its surface is lubricated with machine oil and placed in a box for storage.

Using a plunger

This device is used when deposits form in the siphon, when there is no desire to disassemble the device. Next, we will describe how to get rid of smell from a sink using a plunger. To do this you need:

install the cap on the drain hole on the sink;
turn on the hot water tap and wait until the liquid completely covers the cap;
close the valve and alternately move the plunger handle, up and down;
after several such techniques, we remove the device, and some of the sediment from the siphon should fall into the sink;
open hot water and wash off the dirt.

Instead of a siphon, you can use improvised means, for example, a juice or milk carton. In such a container we cut top part, insert it into the drain hole and act like a plunger with periodic up and down movements.

If the cause of the unpleasant odor is in the siphon, then this device can be disassembled. We take out the corrugation from the sewer pipe and substitute a bucket, open the tap and pour water into the sink. If the liquid does not flow, it is necessary to disassemble the siphon. To do this:

place the container and carefully unscrew the cap;
unscrew the nuts and remove the corrugation, remove the blockage;
The siphon is assembled in the reverse order.

At the final stage of work, we check the tightness of the connections. To do this, just turn on the water. If necessary, tighten the fasteners.

Fighting blockages using improvised means

How to remove sewer smell from a sink if you don’t have it on hand necessary equipment? The following tools will help with this:

Pour a glass of salt into the sink drain hole and add 500 milliliters of boiling water. After 3 hours, turn on the hot water.
Mix baking soda and salt in equal proportions and pour into the sink. After half an hour, apply boiling water to the mixture. If the smell remains, we repeat the procedure or use more effective methods.
Pour 2 tbsp into the siphon. Spoons of soda, then pour a glass of vinegar and cover the hole with a rag or stopper. After 10 minutes, rinse the pipes with boiling water.
Pour the contents of a sachet of citric acid powder into the drain and add a small amount of hot water. Chemical reaction should help break up the blockage.
We use special remedy“Mole” according to the instructions on the package. This drug is more aggressive than citric acid or a mixture of soda and vinegar.

You can use other chemicals to remove clogs in your sink. They are bought at a household chemical store and used according to the manufacturer's instructions.

Preventive actions

How to remove smell from kitchen sink? The best way is to prevent blockages. To do this you need:

Use a special mesh to trap food waste in the sink. Do not pour tea leaves or coffee grounds into the sink.
After washing dishes, rinse the pipes with hot water. This will prevent the accumulation of fats in the siphon or corrugation.
Carry out periodic maintenance of the sink. Pour baking soda and vinegar into the drain hole. Such operations must be carried out at least once a week.
If the plumbing fixtures will be inactive for a long time (the owners have gone on vacation), pour a little vegetable oil into the siphon. This liquid does not evaporate, which will prevent the penetration of foreign odors from the sewer system.

Buy high-quality siphons that you can disassemble yourself. In this case, the user will be able to repair the equipment himself without calling a plumber.

Conclusion

There are a huge number of ways to get rid of odor in the sink, but before taking specific actions, it is necessary to identify the cause of its occurrence and choose the most effective means.

Important! If the cause of the unpleasant odor lies in high humidity premises, then the system will help to remove it forced ventilation. Fresh air It will dry out the room and also remove sewer odors.

Sewage problems

The bathroom contains many plumbing fixtures: bathtub, washbasin or sink, toilet, washing machine. All these devices are connected not only to the water supply, but also to the sewerage system.

If during installation the sewerage system is connected to plumbing equipment with technical errors and flaws, an unpleasant odor may arise from the bathroom sink. Most often diagnosed following problems sewer system operation:

Pay attention! Any defect in the installation of a sewer system in a bathroom, be it an incorrectly selected pipe cross-sectional diameter, poor sealing of joints, or an incorrectly set slope, is fraught with an unpleasant odor. Therefore, it is important that the pipes are laid experienced master, which will take into account all these nuances.

How does a water seal work?

Every plumbing fixture that is used in the bathroom and connected to the sewer system has a siphon. A siphon is a special device that does not allow foreign odors to penetrate from the sewer pipe into the room. It is made of brass, plastic or other material.

There are models of siphons with a water seal, a membrane seal and a dry seal. Thanks to its special curved shape with one elbow, this device creates a water plug inside that prevents air from the sewer pipe from entering the sink or bathtub. Siphons perform the following functions:

Removes unpleasant odors that may enter the room from the sewer pipe. While the plumbing fixture is being used and the water in the water seal does not dry out, air from there cannot penetrate up the pipe.
Protects against sewer blockages. They filter out large debris that ends up in your sink or bathtub drain. All large impurities fall into the siphon sump, after which it can be removed from there.
Sewage is directed by gravity into the sewer system. The shape of the siphon is such that through the drain waste water easily flows into the sewer without stagnating at the bottom of the sink or bathtub.

Please note that the water seal only works until the water in it dries out. Therefore, when no one uses a plumbing fixture for a long time or there is no water supply for a long time, the liquid in the siphon dries out, which is why there may be a sewer smell in the bathroom.

If the reason that the bathroom smells is because the water seal has dried out, then the easiest way to deal with this problem is to simply fill the siphon with water and thoroughly ventilate the room.
