What to do when an unpleasant odor appears?
A bathroom is a sanitary-hygienic premise necessary in each apartment, which requires special care. If tenants comply with sanitary requirements, the toilet should not have any odors, including the smell of sewer gases.
In order to eliminate the unpleasant scent of the sewer, spreading to other rooms, you should first identify the cause of its appearance.
With gases from the sewage system, not only pathogenic organisms can penetrate into the room, but also various harmful substances - hydrogen sulfide, sulfur oxide, ammonia, mercaptan and others.
Inhalation of these gases is harmful to humans and may be harmful to human health. Therefore, if there is a sewer smell, you must immediately identify the source of its appearance and eliminate the problem.
The first thing that owners of a room who usually have no idea about the features of the sewer system usually do is use air fresheners.
Modern aerosols have a variety of flavors that can temporarily interrupt the unpleasant smell of sewers, but they are not able to eliminate it.
Possible causes of the appearance of a smell are the flow of gases from a drain hole of a certain or several plumbing fixtures.
Quite often, a disgusting "aroma" appears in the bathroom due to clogged devices or improper installation of plumbing equipment. However, there are other possible odors.
Problems with the operation of the water seal
Most often, the smell of sewage appears in the bathroom if, for whatever reason, the water seal stops functioning normally.
In siphons installed under the plumbing equipment, there is a water plug, which acts as a barrier to the path of gases coming from sewer pipes. If there is no cork for any reason, then the gases penetrate the toilet unhindered, spreading an unpleasant odor.
The siphon is located under the basic sanitary equipment of each toilet - the toilet. It is made in the form of a curved pipe in which a certain amount of water accumulates. The hydrolock acts as an effective barrier to unpleasant sewer odors.
In the event that significant violations occur in the operation of the siphon, a constant sewer smell will be observed in the apartment. Consider the main reasons why the siphon ceases to perform barrier functions.
Problem # 1 - Incorrect siphon installation
Mistakes made when installing a water trap provoke the appearance of a bad smell of sewer gases.
Suppose that during the installation of a bottle type siphon, the outlet pipe of the pipe was set too high. In this case, the gases from the sewer will pass on top of the water plug, due to which the siphon will not be able to fully function.
To fix the problem, the outlet pipe must be moved - it should be located 2-3 centimeters below the water level.
Problem # 2 - Water Cork Drying
If any plumbing equipment has not been used for a long time, the water plug may dry out. As a result, sewer gases will freely enter the toilet.
In this case, troubleshooting will not take much time and effort. Water must be secured so that the breech block is completely filled.
If you plan to leave the house for a long time, it is recommended to pour a little vegetable oil into the drain. The film will reduce the rate of water evaporation and increase the time period, due to which the water plug will not dry out quickly.
Problem # 3 - Stretching Corrugated Pipe
When using plastic siphons with a corrugated pipe, a bad smell can occur due to the fact that the corrugation has sagged over time. This often happens when not special clamps are used to fix the knee, but an electrical tape or ordinary adhesive tape.
To eliminate this problem, it is necessary to give the corrugation the correct position and fix it with a clamp.
Problem # 4 - incorrect installation of the corrugation
An unpleasant sewer odor in the toilet may indicate that installation rules have been violated corrugated water seal. It's about bending to form a siphon.
If the installation of plumbing is carried out by an inexperienced specialist, he may not know that the corrugated pipe should be bent with a knee, and then fix it in this position. Sometimes the bending of the corrugation is made insufficient.
To correct the installation error, it is necessary to bend the corrugated pipe to the desired configuration. After that, it is necessary to fix the corrugation with a special clamp made of plastic. For the installation to be successful, it is recommended to use the services of a specialist.
Problem # 5 - siphon clogging
An unpleasant odor of sewer gases in your toilet may be caused by normal clogging. plumbing siphon. The sewage settles in the siphon knee and begins to decompose, releasing a fetid odor.
In case of clogging of the water seal, it must be washed. You can use chemicals for washing, which are sold in household chemical stores. In some cases, mechanical cleaning of the hydraulic seal is necessary.
More often corrugated siphons get clogged in practice. This is because they have a folded surface on the inside of the plastic pipe. This feature of the corrugation design contributes to the retention of garbage, grease, waste and other effluents. In order to rinse the corrugated siphon, it must be completely dismantled.
Stable operation of siphons, through which plumbing is connected to the sewer, will be ensured by the installation of a vacuum valve:
Other types of problems
If there are no problems with the water seal, then you will have to carefully examine the room, paying attention not only to the sewer system, but also ventilation and other nuances. We will try to understand in more detail what exactly can cause stench.
Reason # 1 - clogged sewer pipes
To successfully eliminate the clogging of pipes installed in the bathroom of an apartment or house, it is enough to purchase a special chlorine-containing agent.
For effective cleaning of sewer pipes in the bathroom and the bathroom, preparations from leading manufacturers are often used: Domestos, Deboucher, Tiret or Krot.
The drug is poured into the sewer for a certain period of time. Due to the effective action of modern household appliances, the blockage usually disappears, and the normal functioning of the plumbing device is established. If the household chemical product does not clean the pipe, then it is necessary to call the plumbing.
Reason # 2 - installation errors of the sewage system
Not only problems with the siphon can be the cause of the defective work of the sanitary equipment. The cause of the narrowing of the lumen in the pipe may be a clogged sewer. Methods sewer pipe cleaning detailed in our recommended article.
In this case, pipe cleaning is required. Errors that were made during the installation of the sewer system lead to breakdowns and drying out of the water plug.
In some cases, when installing plumbing equipment, pipes of small diameter that do not comply with construction standards are used.
For normal operation of the sewer system, it is necessary that the cross-section of the pipe is not completely blocked by drains, otherwise a discharge will occur in the pipeline, which will lead to the failure of the installed water seal.
A clogged fan pipe is a common cause of plumbing malfunction. This element is displayed on the roof of the building and is designed to equalize the pressure in the installed sewage system.
The fan pipe may become clogged (for example, it is blocked by an ice plug in winter), as a result of which a discharge occurs in the sewer system.
Each time you drain the water (for example, when operating the toilet flush tank), the siphons break and the gases penetrate into the room. To eliminate the cause of the smell, clean the pipe.
Reason # 3 - system leakage
Reason for the appearance toanalytical smell may be a leak in the pipe or connections. It should be noted that it is not always possible to quickly locate a leak.
Sometimes a hidden installation of pipes is performed in the bathroom, which complicates the process of finding a problem. Drains flow slowly from the leak and lead to mold growth and an unpleasant odor.
Plumbing equipment leaks may be in the most unexpected places. For example, it is quite difficult to detect leaks in the slab. The most common cause of leakage and the appearance of a sharp sewer smell in the toilet is a loose connection of the corrugation and the drain pipe.
Having found this defect, it is urgent to replace the corrugation, as well as restore the mandatory tightness of the pipe joint. If leaks in the connection between the sewer pipe and the siphon are found, sealant must be used.
The silicone layer will reliably protect the joint area of the elements of sanitary equipment from leaks.
Reason # 4 - poor ventilation performance
In the toilet and in the bathroom, water is used daily, so in these rooms there is an increased humidity. To successfully combat this phenomenon in the bathroom and other of the above premises, it is mandatory ventilation system.
Most apartment buildings use a natural exhaust system, but it does not work effectively in every case.
In order to check how well the installed ventilation system works, a simple test should be performed. It is necessary to take a sheet of paper and bring it to the ventilation. If it works efficiently, then the sheet is pressed against the grate.
If the paper sheet falls onto the floor, the ventilation system does not work properly and needs to be cleaned.
In some cases, cleaning the ventilation ducts does not bring the desired result, then there is a need for the construction of forced ventilation.
Additional equipment is usually installed in the hole for natural ventilation. The second fan is turned on as necessary - when using the bathroom.
To avoid ventilation problems, clean the ventilation holes as often as possible. For better air exchange, it is better to install a hood equipped with a check valve.
Reason # 5 - Incorrect pipe installation
It happens that a sharp sewer smell appeared in the toilet or in the bathroom almost immediately after moving into a new apartment or house. In this case, the cause of the stench must be sought in an illiterate sewage system.
Today, there are specific norms for laying sewer pipes that must be observed during installation. If there is a breakdown in the sewer, you will have to reinstall the pipeline, which will entail considerable expenses.
Incorrect stench and stench arrangement of sewer pipesor rather, non-compliance with the optimal angle of inclination.
You can fix the error only by dismantling the system and installing sewer pipes under the right slope. You will learn from what angle it is laid to lay sewer pipelines from the article we have proposed.
If plastic elements are used, it is necessary to repair pipe joints that are loose. It is enough to install sealing cuffs or change gaskets.
Now, home owners prefer to build their own buildings. In this case, in order to avoid misunderstandings, it is better to entrust specialists with the development of a project of engineering networks and the installation of a sewer system and plumbing equipment.
Reason # 6 - non-compliance with hygiene rules
The owner of any dwelling should understand that one of the most common causes of unpleasant odors in the bathroom is non-compliance with hygiene rules.
The reason for the stench may be untimely washing off of waste products and a rare washing of plumbing equipment.
To care for the plumbing in the toilet, it is enough to follow simple sanitary requirements and regularly wash the toilet with special means. They effectively kill microbes, saving the bathroom from the causes of a bad smell.
In the modern market of household products, disinfectants have proven their worth: Domestos, Toilet duckling, Dosia, Oda, Cillit Bang, Comet.
Toilet odor control products
Before ascertaining the causes of the sewer smell in the bathroom and eliminating the breakdown, it is recommended to use special household facilitiesthat temporarily eliminate an unpleasant odor:
- Fresh air automatic odor dispenser or aerosol.
- Stickers stripes or blocks that are attached to the toilet.
- Flavored tablets for toilet flush tank.
For a country house and cottage, special care products are used country toilets and behind the cesspools.
The preparations contain bacteria that help to quickly process the entire contents of the toilet, eliminating the unpleasant odor of the sewer. More commonly used brands: Saneks, Bioforce septic, Septic Shock.
No. 1 - microspray and aroma dispenser
Both tools are attached to the bathroom wall. Their difference is that microspray gives out aroma after clicking on it, and aroma dispenser allocates it automatically during the day. In this case, the aroma is served after a certain period of time and in a metered amount. Among the popular brands - Glade, Airwick.
Alternative option - helium freshener. It can be attached to the wall of the bathroom or put on a shelf. It deodorizes the room with pleasant aromas for 60 days.
All of the above funds superficially and temporarily solve the problem of unpleasant sewer odor in the toilet, but they are not able to kill germs, remove pollution and eliminate the cause of stench.
No. 2 - flavored tablets for a tank
An effective tool to get rid of the sewer smell is flavored tablets. They sink into the toilet flush tank.
