The cause of the smell of sewage can be an error in the installation of the system, blocks and incorrect ventilation. We tell how to eliminate these problems.
An unpleasant smell in the house is a faithful symptom that something is wrong with the sewer. And well, if this is a sign of a local breakdown, which is easy to eliminate. The smell may indicate an incorrect device of removal pipelines, which is fixed only by their complete shock. Find out why the house smells the sewer and how to deal with it.

Causes of the appearance of odor
The appearance of sinic in the rooms is always extremely unpleasant surprise. There may be several reasons for this phenomenon.
Errors in design and installation system
Most often, the problem occurs when communications are designed or carried out with errors. This may be incorrectly selected pipe diameter; The hydraulic height ladder is lower than calculated in the project; The wrong bias of the pipeline, which leads to the storage of water or their reverse current and siphon getting into the siphon and, therefore, to a unpleasant aroma. A possible way to eliminate such errors is the dismantling of the old system and the assembly of a new or in some cases the replacement of problem nodes.
So, if the required diameter of the pipe or the slope of pipelines (2-3 cm per 1 m length) is not sustained, on unnecessarily gentle areas there is a risk of breakdowns, and if the slope of the pipe is too large, the mass fills the entire section of the pipe. When the fluid moves behind it, the vacuum (vacuum) is created, which literally sucks water from the hydraulic assets in the sanitary pribor. And if there are no water in them, the evaporation of the sewage pipes without problems fall into the room of the bathroom. It becomes clear why it smells of sewer from sink and other plumbing devices.
A similar disruption of the hydraulic assembly occurs when a single amount is reset too much liquid. Sometimes it can be corrected, moved the point of connection of the reset source. For example, the disruption of the hydraulic assembly began to occur after connecting the drain of the washing machine to the siphon of the washbasin, which is connected to the drain pipeline with a rather narrow corrugation. If you transfer the dope of connecting the washing machine directly to the sewer pipe or onto the riser, then the disruptions of the hydraulicate in the washbasin will be avoided.
Faulty ventilation
When pumping the effluents in the sewer channel there is a vacuum that must be compensated at the expense of air flow through the pancake or sewer aerator. Otherwise, the plumbing of plumbing hydraulic assets occurs. Therefore, due to the lack of ventilation or incorrect operation in the room may via. Consider the problem more.
When the water moves in a rudder, the vacuum formation is prevented by organizing the organization of air flow from the outside - through the fan tube (the upper part of the rising, which is derived to the roof) with a ventilated channel either through the sewer aerator (reverse air intake valve) with a non-ventilated riser. In the latter case, the adjustment of the ventilation channel, which takes place gaseous fermentation products from the home sewage system (septic) is also required.
If for some reason, the withdrawing openings of the fan riser or ventilation can be clogged, normal operations to brake drain are also violated. If the fanset was clogged (for example, fallen foliage got into his withdrawing hole), then the smell will appear periodically, when resetting a large amount of water (for example, from a washable tank). When clogging a street ventilation channel, the fragrance will gradually leak through the hydropitum.
Errors in the operation of siphon nodes
This is one of the frequent reasons why the toilet smells the sewer. The smell appears due to the improper installation and operation of Sifone Sinterhribors. This is the name of the node in which the water cork is formed, which prevents the penetration of sewer gases.If there is no water (a few weeks) through the siphon for a long time (several weeks), the liquid in the hydraulic manner can evaporate, and it will start skipping the smell. Therefore, it is recommended regularly (1-2 times a month) to carry out water discharges through each siphon and ladder or immediately install a node with a dry shutter. Similar models are usually several times more expensive, but they never dry.
Lamb and leaks
When the pipeline breaks, the system may not work correctly, which leads to the appearance of sinic. Another reason is to leap the effluent or the tightness of the gasket of the compounds, from where the smelling air is seeping. Recovery of normal operation is achieved by cleaning the blockage or repair of the leak place (replacement of the gasket).
How to eliminate the smell of sewage in the bathroom, kitchen, toilet
We disassemble the main reasons why smells of sewage in the bathroom and other rooms. Almost all of them can be eliminated independently. Let's talk how to do it right.Elimination of design and installation errors
If the stench appeared after major repairs or laying new communications, it should be assumed that the problem is in illiterate design. Unfortunately, the correction of errors in this case is very laborious and costly. It is necessary to dismantle the communications and lay them again, but without deferrators. Sometimes "shown" partial dismantling and alteration of individual nodes.
So, for example, in the absence of revision luchkov, through which inspection and repair of communications is carried out, they are installed in the process of partial dismantling. In more serious cases, it is necessary to redo the system. If there is no experience in conducting such work, it is better to trust their specialists.
Repair or installation of ventilation
If there is no fan riser, and it smells unpleasant in the house, it makes sense to consider the possibility of its arrangement. It is necessary in three cases: for buildings in which more than two floors, for autonomous systems in private houses, for sewer rims with a diameter of more than 50 mm. It is advisable to install the design where one-time drains of large volumes are possible, for example, in the presence of a pool or such structure.
Already installed ventilation during operation can be clogged. So, the channel-derived canal is sometimes clogged with ice, snow or leaves. Therefore, if the room is unpleasantly smelled, and after washed in the toilet, the sharp sounds of broken hydraulic spots are heard, it is worth ensuring that there is no clogging. To do this, a cable is lowered from the roof to the canal and check how free it passes. If necessary, a scored mine can be cleaned from above or through revision shells.
Liquidation of blocks and leaks
The clogging of the pipeline is the most common cause, why smells the sewage in the bathroom, we will examine how to get rid of the problem. Contamination of the outer surface of communications with poorly soluble household waste (fat, soap, food residues) leads to deposits on the walls. Gradually, their number increases. The lumen through which the fluid moves, narrows, and then clogs. Several methods are used to eliminate deposits.
- Dissolution. The industry produces special chemical drugs that dissolve clogging, such as "Mole", "Tiret Turbo", etc. They are flooded in stock, after the time specified in the instruction, the mud plug is dissolved, washed off with plenty of water.
- Pumping by Vatuzom. This is a device that creates increased pressure in the pipeline. Due to this, the clogged area is cleared or a traffic jam is moving on. Vanutuz is placed on draining sink or toilet bowl, overflow holes are closed, pumping is performed.
- Cleaning a plumbing cable. Helps break or pull out the plug out. Before you start cleaning, you need to dismantle the siphon node.
After removing the break, the system begins to work normally, there will no longer smell in the room.
Small leakage when the liquid slightly leaks or becomes a very thin flowing, also give an unpleasant fragrance. Most often, the problem is in disruption of the tightness of the compounds or in damage to the pipeline. In the latter case, "shown" replacing the defective element, but repair is possible. More often is a temporary measure. Small holes are sealed with epoxy resin or cold welding.
Cracks and larger holes are covered with piping from plastic hermetic material and glued them to the base. For reliability, it is desirable to wind up the entire defective area. For example, winding it with a bandage, to coat it with epoxy resin. You can apply a patch, on top of it put a PVC pipe fragment for amplification and fix all clamps. Such temporary repair is possible in the bathroom, bathroom or in the kitchen. Where there is relatively free access to communications.
Preventive measures
- Regularly inspect the ventilation shaft. To cover it on top of a protective grid so that the garbage does not get into the channel.
- Put mesh on plums in the bathroom and in the kitchen so that they delay the remains of food and hair. Regularly use chemical preparations for preventive purposes for washing communications.
- Once every six months inspect the available areas of the pipeline for small leaks. When detecting defects immediately correct them.
These simple events will help maintain the sewer system in health, which guarantees the lack of unpleasant flavors in the house.
