Signaling

The bathroom is a place that is traditionally associated with cleanliness; it is there that we cleanse our body from the dust of the big city, and our head from unpleasant thoughts and worries. However, sometimes a repulsive, fetid aroma of sewage can spread throughout this room.

The first reaction of the housewife, who realized that the inside of the bathroom did not smell like flowers, was to wash everything she could with a strong detergent. However, if this measure saves, it is temporary, and sometimes it does not bring any result at all. In this article, we will tell you how to remove smell from your sink so that it never comes back.

What causes sink odor?

An unpleasant smell from the sink is a serious problem that not only violates sanitary and hygienic standards, but also annoys any housewife. There are many reasons.

Through which sewer “odors” can escape and fill the room with a stench. More often bad smell in the bathroom they call:

Important! If the reason 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: a bathtub, a washbasin or sink, a 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. The most commonly diagnosed operational problems are: sewer system:

Note! 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 wastewater easily flows through the drain into the sewer system 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.

How to deal with the problem?

Many housewives are wondering how to eliminate the smell from the sink in the bathroom, how to get rid of the persistent aroma of the sewer, if a sponge and detergent no longer help.

If the bathroom is cleaned regularly and thoroughly, but the odor is still present, then the problem is most likely in the sewer system, so we will deal with it. To get rid of sink odor, follow these instructions:

Remember! We clean the bathroom quite often, because keeping it clean is not easy. However, we often forget that the pipes and siphon need to be cleaned periodically so that no unpleasant odors bother you. In addition, it is necessary to carry out preventive measures: you should not throw cleaning materials, garbage, grease into the sink, you need to clean the siphon sump and change the corrugation on time.

Video instruction

It seems that all hygiene rules are being followed, but the sink still emits unpleasant sewage odors from time to time. And it’s not always possible to get rid of them - without knowing the cause, it’s difficult to eliminate the consequences.

Why does a foul odor occur?

Before you figure out why your sink smells like sewer, you should have an idea of how the system works. All plumbing fixtures(bath, toilet, sink, washbasin) drain pipes converge into one common sewer system, passing through all floors of the riser, which has an exhaust hole in its upper part.

Check and replace, if necessary, sink drain pipes

All sanitary fixtures in the area before entering the sewer pipe have a special siphon in the form of a curved elbow, the main function of which is to hold the water seal. This water “plug” in the elbow prevents odors from the pipes from entering the room.

The main reason for the stench in the kitchen is problems with the water seal:

The knee may not be positioned at the correct angle or height.
If the siphon is made of corrugation, then over time it loses its shape.
The device had not been cleaned for a long time, and residual grease had accumulated on the walls.
If the sink has not been used much, the water in the seal may evaporate.
Moisture also evaporates if heating pipes pass under the sink.

Another reason why an unpleasant odor may appear in the kitchen is flaws in the installation of the system. Poor sealing of pipes and incorrectly selected cross-section diameters will be the culprits in the penetration of sewer odors into the kitchen.

It is no coincidence that the common sewer drain pipe has access to the attic of the house - this is necessary for ventilation of the system and removal of cloaca aromas to the outside. Sometimes, during renovations, residents of the top floors simply remove the “extra” (in their opinion) section of the pipe, thereby blocking the exit. It is not surprising that the smells will spread throughout all the apartments of the riser.

checking pipes for tightness of connections

How to fix the problem?

When your sink smells like sewer, what to do and what not to do becomes a pressing question. But you definitely don’t need to grab an air freshener: it won’t kill the stench, and it won’t remove it. It is necessary to look for the cause and eliminate it.

To do this, an audit of the entire system is carried out to eliminate malfunctions, leaks, and depressurization. The main attention should be paid to the water seal. To do this, it is advisable not only to inspect the siphon from the outside - it should be temporarily dismantled to check for blockages.

It is better to replace the siphon made of corrugated material with a new one. Do not try to return the old device to its previous state - this is a temporary measure, because... a deformed corrugation, even on wire hangers, will poorly retain water in the seal.

It is enough to clean siphons made of other materials (plastic, metal) from the inside if they are not damaged. When reinstalling, check the correct slope, the height of the pipe and the ratio of pipe diameters. The joints should be reliably sealed.

checking the water seal system

But you should not connect the sink directly to the sewer by removing the water seal elbow. Without a siphon, the smell will penetrate even more into the premises, becoming persistent.

If the cause of the smell is errors in the installation of the sewerage system, do not try to eliminate them yourself - entrust the work to an experienced plumber. As in the case when the neighbor above cut off part of the sewer pipe, let a specialist solve the problem.

Sink cleaning products

Sometimes, in order to find the answer to the question of how to eliminate the smell from the sewer in the kitchen, it is not necessary to immediately unscrew the siphon. You should try first chemicals for cleaning pipes - maybe the reason is only that the drain is clogged with greasy waste.

The following products have a good cleaning effect: “Domestos”, “Mole”, “Brawler”, “Odorgon”. Use them according to the instructions on the packaging, observing all safety measures (these chemicals are toxic). Sometimes it is enough to use a solution of bleach or bleach.

The drug is poured into the sink and after a certain time is washed off with copious amounts of water. If one time is not enough, you can repeat the procedure after a couple of days. But if this doesn’t help, then start dismantling the siphon.

cleaning the pipe without removing it with chemicals

Folk remedies

Chemicals may not always be at hand, and the stench becomes intrusive. How to get rid of sewer smell in the kitchen in this situation? Some foods may be useful as a disinfectant:

Table salt (preferably rock salt) is poured into the sink drain hole and the plumbing is not used for 3 hours. The pipes are then washed with plenty of water.
Baking soda poured into the pipe will also work. Next they pour in table vinegar and leave it like that for half an hour. In this case, it is advisable to cover the drain hole with something so that foam does not come out (a derivative of the reaction of soda with vinegar).
You can also use dry mustard - it will both clean the sewer pipes and block the unpleasant odor.

Washing soda can also help. It is first filled with boiling water and immediately poured into the sink drain hole. But the procedure must be carried out carefully, because... the reaction will occur instantly, and the bubbling solution may harm you.

regular cleaning of pipes and checking the elbow for blockages

Preventive measures

The smell of sewage from the sink can be avoided if you follow some rules for caring for your plumbing:

The drain cleaning procedures described above should be carried out not only when a persistent smell appears from the sewer. It is necessary to clean the drain (and not just in the kitchen sink) at least once a month. And salt or soda can be used even more often - once a week. This will keep the pipes relatively clean.
Do not throw leftover food, tea leaves, etc. into the sink. Their small particles, having penetrated the siphon (especially if it is corrugated), clog it, preventing the water seal from functioning normally.
When going on vacation, take care of the condition of the water seal so that you are not surprised by a foul smell when you open the apartment door. Oil (vegetable or machine oil, it doesn’t matter) will help slow down the evaporation of water in the siphon. Pour it down the sink drain (about a shot glass) and drive away quietly. When you return home after relaxing, flush the system warm water using a pre-cleanser.
If there is a need to replace the siphon or other sewer pipes, you should not invite a neighbor or friend who has little knowledge of plumbing work. To avoid any complaints, entrust this task to a specialist.
When choosing a new siphon, do not rely on the advice of inexperienced people and do not rely on the price of the product. The main argument should be quality and ease of use. If further maintenance of the siphon is expected on our own, it is better to buy the flask version (it is also called barrel-shaped). There is a special, easily removable element that allows you to clean the siphon without completely dismantling it.

If the appearance of sewage smell from the kitchen sink is not always the fault of the apartment owners, then eliminating it depends only on them. Maintaining basic hygiene while conducting preventive measures, without relying only on your (sometimes illiterate) abilities, without saving on money, the stench can be, if not completely avoided, then actually reduced.

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 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 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.

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

But even a slight reduction in the diameter of the sewer pipe is 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 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.

Rubber gloves will protect the skin of your hands from the harmful effects of 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 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 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 evaporated as a result long downtime . 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

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 the odor, and washing soda helps 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. Chances are the cause of the problem is more serious than you think, and by ordinary means there is no way to get rid of it. In this case, do not overuse air fresheners. It’s better to try to replace the system quickly if this is the reason, or ask general condition sewerage in your home. In the latter case, you should seek help from the appropriate services.

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 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 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 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 drastic actions the pipe may be damaged. 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. For plastic pipes use warm water with diluted in it 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 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 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 preventative 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.

Leaving for long time, you need to prevent the appearance of a fetid odor throughout 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, constant maintenance order in the kitchen or bathroom is the key to freshness and cleanliness. However, regardless of the degree of tidiness of the housewife, sometimes the kitchen air does not smell like fragrant baked goods, and the smell in the bathroom is reminiscent not of the freshness of the sea breeze, but of ominous footage from horror films.

Let's consider, 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 sharp changes temperature of the hot and cold water. In this case, you can try to solder it using construction hair dryer and a piece of plastic, or seal 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 eliminate more severe blockages a plumbing cable is used. Rotate this device and periodically turn on the water supply. This will help you deal with clogged drains faster. In the case of plastic pipes, this method should be used very carefully.

If there is no plumbing cable, 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 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 instead of a siphon corrugated pipe. 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 into the siphon machine oil 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 straight sections of pipelines are repaired by applying bandages or sealing clamps. Large holes sealed with 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.

To clean sewer pipes, chemicals containing caustic soda are used, 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, which contains 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.

When purchasing cleaning chemicals, pay attention to the possibility of using them for plastic pipes, if such drains have 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, wash the drain 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.

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 there is an unpleasant 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 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;
contamination of the inner surface of pipes with fats and food residues;
deformation of the 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 and the location of heating pipes under the valve. 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 of 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 and cracking of plastic pipelines;
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 eliminate the problem with an unpleasant odor than to harm yourself and your loved ones.

Effective ways to eliminate sink odor

You can remove odor from your kitchen sink 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, which reduces the capacity of the pipes. The adhesion of fat and food provokes a putrid odor. It will help to remove the traffic jam metal cable. 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. The 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. The siphon needs to be inspected. If the problem is caused by stretching of the corrugation or improper installation of the structure, it is enough to install everything correctly and fix it. If the stench is caused by a blockage, the siphon and drain are cleaned 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 hot water tap is opened. After the cap is closed with water, you need to firmly press the handle of the device several times. This is necessary to pump water up and down and destroy 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-removable 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 using 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 drain hole of the sink, let it sit for 20 minutes, then rinse the sink with large quantity water. This method can also be used for prevention.

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 should not endure the unpleasant and rather dangerous smell of sewage in a place where the whole family gathers, and the housewife spends most of the day preparing everyone's favorite dishes.

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 tidiness of the housewife, sometimes the kitchen air does not smell like fragrant baked goods, and the smell in the bathroom is reminiscent not of the freshness of the sea breeze, but of ominous footage from horror films.

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

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 can burst due to sudden changes in the temperature of the hot and cold water being drained. In this case, you can try to solder it using a hair dryer and a piece of plastic, or seal it with 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

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 clogged drains faster. In the case of plastic pipes, this method should be used very carefully.

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

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. Various methods are used to eliminate them. 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.

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

To clean sewer pipes, chemicals containing caustic soda are used, so handle them carefully and carry out all work with rubber gloves.

Chemicals used to remove blockages and unpleasant odors from drain pipes

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.

When purchasing cleaning chemicals, pay attention to the possibility of using them for plastic pipes, if such drains have been installed in your home.

Traditional methods

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 acetic acid solution is used in the same way. 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.
