Tortured odor from the toilet bowl canalization, you can eliminate yourself

An unpleasant odor can appear in any of the rooms where there is a sewage system. Typically, such problems are found in the toilets, less often - in the kitchens and in the bathrooms. In order to eliminate the odor from the toilet bowl by the sewage system, the tenants of the apartments make abundant use of cleaning chemicals, air fresheners and other achievements of civilization. But only they are able only for a short time to disguise the sewer "aroma" without eliminating its cause. We'll figure out what to actually do with such a problem.

Odor from the toilet - the causes of

Residents of apartments and cottages, new and old houses at times wonder: why stinks from the toilet bowl sanitation? Such "aromas" can seriously spoil the mood, especially for people who have a sensitive sense of smell.

It is worthwhile even to open the door to the toilet for a short while, as the smell spreads throughout the housing. In order to truly solve the problem, it is necessary to identify the reasons. Let's look at the most probable:

• The toilet was not used for a long time. The water left in the depth of the sink, just faded, hence the unpleasant odor.
• There was a clog in the toilet drainage pipe. Even despite the large cross-section of the pipe, this option is quite possible. As a rule, this happens if a rag, a too much food waste or a plastic bag is inadvertently in the toilet. As a result - other sewage wastes are very poorly washed into the common sewer pipe, lingering near the toilet drainage outlet, they decompose, because of this stink from the toilet.
• Sewage congestion or blockage can be much more serious and happen somewhere at the basement level in an apartment building. If this happens, usually the unpleasant smells are felt by the tenants of the first floors.
• In the houses of old buildings - ancient cast-iron sewer pipes. This material is highly resistant, however, for several decades of operation, microcracks can form there. They are not so large as to start leaking, but they can already start to leak sewer smells. Due to the fact that the toilet and the riser are located nearby, the sources of odor are easily confused.

There are two more reasons that lurk where the toilet outlet comes into contact with the main water drain on the house:

1. The plastic bowl for the toilet bowl or the sealing collar is broken.
2. Initially performed incorrectly work on connecting the toilet bowl to the sewer system at home.

Important! Some of the compacts have a horizontal outlet pipe( parallel to the floor).If the connection fails to withstand the correct gradient, then the subsequent stagnation of sewage can not be ruled out.

Removing installation errors

If your toilet stinks from the toilet and you see that the sewerage system is not properly installed in it, in order to eliminate this cause, you will have to completely or partially rework the sewerage system. Due to the fact that part of the sewerage is located in hard-to-reach places, it will be necessary to dismantle sanitary and technical devices that are located in this room.

Often it happens that it stinks in the toilet due to a violation of the slope of the sewage pipeline. It is very important to get rid of this problem in a timely manner, because the stagnation of sewage in pipes can not only cause the "fragrance" of sewage, but also promote the propagation of harmful bacteria.

If the problem really is in the wrong slope of the pipes, then you need to re-do the sewer from the main riser to the toilet.

To be sure to get rid of an unpleasant odor, you must first design the slope of the pipes. It should be one centimeter for every meter of length. In this case, you can fully use different versions of the slope of the sewage pipeline:

• The surface slope is made if from the main riser to the toilet you can lay a pipe of the same cross section with the required gradient.
• If the floor construction does not allow for a surface slope, you can make a step. In this case, pipes of different diameters are used with a gradual increase to the riser.
• In order for the required slope of the sewer pipes to appear, pipes with beveled bottom( cone shape) can be used.

Important! If it stinks from the toilet, then to eliminate this smell, it is necessary to make tight joints of pipeline segments:

• For the special sealing of the pipeline connections from plastic, use special couplings and silicone sealant.
• To seal the joints of the pipeline from the cast iron, it should be zachekanit. To do this, the joints are treated with chisel impacts.

Problems with the hydraulic shutter

When asked why the stove is stinking from the toilet, you should pay attention to the integrity of the water seal - it is a water stopper that is located in the specially curved segment of the sanitary ware that remains after washing the water. As a result, the smell of sewage can not penetrate the bathroom through a water seal from the main sewerage pipeline.

Important! Water from the shutter can not produce an unpleasant odor, because it is constantly updated with new portions when flushed in the toilet.

Problems and their solution

However, if there is still a "fragrance", it is necessary to check if the hydraulic shutter works correctly. This part may not work properly due to the following reasons:

• If the pressure in the main sewer is too high, the hydraulic seal does not cope with its functions. This is because there is no background ventilation. As a result, air from the sewage system displaces water from the water seal. As a rule, this process is accompanied by the formation of bubbles and characteristic bubbling. In order to eliminate the problem, it is necessary to regulate the ventilation of the main sewage system. It will be enough to check whether the ventilation ducts of the sewerage system are hanging on the roof of the house.
• If the configuration of the pipeline that goes from the sink or the bathtub is incorrect, then the water trap also can not function fully. In this case, you need to change the pipe or install a full siphon instead.
• An unpleasant smell from the sewer can be associated with a blockage in the sewage pipe. At the same time, wastewater is not washed into the pipe, but is installed in a sanitary fixture.
• If the smell is present in an unheated room in winter, then the problem may be the freezing of the pipeline. To prevent this from happening, such pipes should be carefully insulated, for example, with the help of mineral wool, or in winter they should be heated( for this purpose, you can apply a heating cable).To solve the problem that has already arisen, it is enough to drain hot water into the sewerage system, which can melt an ice cork.
• Sometimes a sewer smell may appear due to an incorrect configuration of the corrugated tube going from the sanitary unit to the sewerage line. To eliminate this problem, bend the corrugation at the desired angle with your hands.

Other causes and their elimination

When asked why it stinks from the toilet, it is necessary to take into account that corrugation itself can be a source of unpleasant smell. This may be the following reasons:

• Sometimes, through microcracks in the corrugation, urine and effluents can leak into the room. In this case, you just need to install a new corrugation, especially since this is not a very expensive product.
• Corrugation may form in the corrugation and cause unpleasant odors. Then the corrugation will have to be removed and cleaned. In doing so, check the integrity of all seals.

Removing old leaks

Hidden leaks in the toilet may not cause a noticeable flood, but the smell of sewerage may be present. In this case, even a well-functioning ventilation system can not eliminate the stench completely.

Important! As a rule, such micro cracks are located in the upper part of the sewerage pipeline, so that drains do not leak through them, but smells can come out constantly. The only problem is the detection of a microcrack. If the leak is located on the pipeline section located in the interstitial overlap, it is almost impossible to find the place of the hidden defect.

Detecting a problematic site

In order to facilitate the search for such places, you can use a brush and soap solution:

1. This solution is applied to the joints where the greatest chance of depressurization.
2. Then the water is drained into the drain. Due to the fact that the air pressure becomes higher, air can escape through the junctions and microcracks. With the use of a soap solution, bubbles will form in such places.
3. If you find a leak on a plastic pipe, then this place should be applied a special sealant. On the sewer pipe made of cast iron, the places of leakage are sealed with cold welding.

Precautions for preventing microcracks

To avoid the problem of why stinks from the toilet, you should use preventative measures to protect the pipes from hidden leaks:

• Use only high-quality products for sewage system assembly.
• If you use the hidden location of engineering communications, be sure to install rubber hatches to monitor the condition of the system.
• Try not to design a sewer system so that the number of joints, connections and repetitions is minimal. Thus, you reduce the likelihood of leaks and blockages.

Fighting the clogging

If stinks from the toilet because of blockage, the way to eliminate it will depend on the cause of its appearance:

• Sometimes the clogging of sewage occurs due to the accumulation of residues of toilet paper and hair that grab large particles of themWastewater. For this reason, an unpleasant smell may come from the sewerage. To get rid of this problem, it is enough to clean the blockage with a plunger, cable or special chemical agent( Tiret, Sanfir, Domestos).
• Kitchen drainage is often clogged due to fat deposits that not only smell bad, but also make it difficult to drain water. To eliminate such clogging, it is necessary to periodically pour boiling water into the pipes in sufficient volume.
• If you have too much tap water, then the cause of the blockage can serve as calcareous deposits. To effectively combat them, you need to use special chemical compounds to dissolve the raids or vinegar, soda.
• It will be much more difficult to extract construction debris and rags from the sewerage, which can cause serious blockages. With this problem a plumbing cable will help.

Ventilation problems

Often unpleasant "flavors" in the bathroom may be present due to poor ventilation. It is advisable to check the operation of ventilation every two months. To do this, bring a piece of paper or a burning match to the vent. With these actions, they must deviate markedly towards the channel.

Important! You can clean the part of the channel in your apartment on your own, but to clean the obstruction of all the ventilation of the riser, you need to work from the roof. It is better to entrust this business to a professional.

If the ventilation duct has been designed so that there is no natural draft in it, you will have to resort to the use of a special fan, which is installed together with the grill in the ventilation duct.

Important! A clogged ventilation duct, in addition to inefficient removal of unpleasant odors, can add to you problems in the form of mold and fungus.

If there is a smell from the toilet bowl, this indicates a malfunction in the ventilation or sewage system. Find out the reason for its appearance and take measures to eliminate the defect. Also, do not forget to repair the pipeline in a timely manner, then unpleasant "flavors" will disappear from your apartment forever.
