Do I need ventilation in the drain pit. How do-it-yourself ventilation is built in the toilet in the country house. Cesspool ventilation in a private house. Installation of natural ventilation

In a private area with an equipped drain tank, such an unpleasant phenomenon as stench is often observed. Properly equipped ventilation cesspool will completely solve the problem bad smell from the drain and accumulation of gases in the tank.

Any ventilation is of two types:

Natural ventilation is the most simple option arrangement of removal from the pit of gases. But, at the same time, it is no different high efficiency. An unpleasant odor will be brought directly to the surface and spread throughout the site, which may cause some discomfort to residents.

For organization forced ventilation engineering calculations are carried out. .they take into account the required length and diameter of the air passage, as well as its distance from the exhaust pipe (if any). It is much more expensive than natural (pipes, fans, engineering services), but it is more efficient.

The design of the ventilation passage

Consider the features of forced ventilation. When it is set up plain cap replaced by a viewing hatch. In such a hatch it is possible to equip an air window. This hole not only acts as a vent for the exhaust gas, but also ensures constant circulation fresh air. This is extremely important for the normal course of fermentation processes.

An additional hole is arranged to the top of the cesspool for ventilation pipe. Experts recommend choosing communications made of plastic - they are more resistant to constant exposure to aggressive environment and have a long service life.

A fan is connected to the base of the pipe in the pit. You can use a conventional deflector with protective caps or buy a special device for a cesspool. To connect to the network, an additional electrical wire, which is directly connected to the fan contacts.

At natural ventilation pipes are used that are installed directly on the lid of the cesspool. The length of such a pipe can be different - it depends on the desired efficiency of the system. But the depth is strictly normalized - the pipe is installed in the drain 20 cm above the maximum level of the tank.

Choosing a pipe for ventilation

Ventilation of the cesspool is easily done by hand. The first thing to do is calculate desired diameter air window or ventilation pipe. According to sanitary standards, the air exchange rate in the cesspool should be at least 80 m 3 / h. To ensure the required level of exchange, it is recommended to use pipes with a diameter of at least 110 mm. To check the correctness of the selected diameter, you can use the formula:

The formula for calculating the required air exchange

Please note that all figures obtained must be rounded up. The required length is selected according to the table and individual needs.

When choosing the height of the ventilation pipe, consider the following:


How to ventilate a cesspool

Natural ventilation does not require a special approach. For its arrangement, an additional hole is made in the inspection hatch for the fan pipe. A pipe of the required diameter is inserted into it. Its upper and lower parts are protected by crates and special cone covers. The higher the pipe, the more intensive the air exchange will occur.

To carry out the installation of the ventilation system of the cesspool with your own hands, you will need special tools and materials for the construction of the system. These are fasteners (steel screws right size), a knife for cutting a pipe or a grinder with a special disk, a puncher for making a hole in a cesspool, a level, a construction tape measure.

Step-by-step instructions on how to independently ventilate the cesspool:


Twice a year, the ventilation system is cleaned of debris and inspected for damage. The fan needs to be checked very carefully. Small particles of solid waste can collect on its blades, which will reduce the efficiency of the entire air exhaust system.

Video: an example of ventilation in a country toilet

Let's talk about the significant moments of the right country toilet, the most important thing, in which is the most effective ventilation. A toilet on the territory of a private house, as you know, is not a luxury, but a direct necessity. When building a toilet on your site outside the city, do not miss the moment when you need to ventilate the cesspool and the toilet cabin itself. True, if you still forgot about it, this oversight can be corrected if you make several holes yourself, providing at least minimal ventilation to the country toilet.

Country toilet: ventilation in the pit

in the house with autonomous system sewers, as a rule, both cesspool ventilation and septic tank ventilation should be arranged. Moreover, the ventilation pipe should be inserted into the drive in such a way that its lower end is 20-30 cm higher than its filling level. If the issue of ventilation of the pit is resolved, it can still accumulate in the cabin bad smell due to the fact that the room is not airtight, the lid does not close tightly or for other reasons. This often happens if the toilet is built unprofessionally. To get rid of the bad smell, there is a backup ventilation option made directly in the toilet cabin.

Country toilet: cabin ventilation

Ventilation of the toilet in the country will require sewer pipes made of plastic with a length of about three meters and a diameter of 110 mm, a connecting angle of 90 degrees, a rain umbrella, a ventilation grill and clamps. A hole is drilled in the wall of the toilet with a metal cutting crown large diameter(120-130 mm), then a place for the hood is marked in the upper part of the cabin, a crown is attached to the drill and a second hole is drilled.

Pipes must be connected by a transitional corner. The design is inserted into the hole, and everything superfluous is cut off from a short piece of pipe. Further assembled structure ventilation of the toilet in the country is attached to the wall with connecting clamps, an umbrella is put on to protect against precipitation. You can control the vertical of the resulting ventilation system for the country toilet using building level. As a completion of the work, two self-tapping screws are screwed to install the ventilation grill inside the room. If there is such a problem as a gap between the pipe and the wall, then fill it mounting foam or cover with sealant.

Pit ventilation device necessary element normal operation sewer system private house, dacha. The accumulation of gases in the cesspool (especially methane) can lead to poisoning, and sometimes to a fire. In addition, ventilation is necessary to establish normal pressure in the system, primarily in pipes.

Ventilation Device Methods

There are two types of cesspools:

  • Autonomous building - septic tank. If the cesspool is located on the site next to the house, the unpleasant smell from the drains will certainly spread throughout the site. How to remove the smell from the cesspool? During construction treatment plant it is necessary to leave a hole in the lid for the ventilation pipe. The cross-sectional diameter of the pipe is from 10 cm. Most often, plastic pipes are used for arranging ventilation - they are light and easy to install. Insert a second pipe with a diameter of 5 cm into a pipe with a diameter of 10 cm.

The pipe is inserted into the septic tank, its lower end must be 30 cm higher than the maximum filling level of the pit. The height of the pipe must be higher than human height so that unpleasant odors go up. The upper end of the pipe must be protected from water, snow, for example, with a special cap.

Such a simple structure effectively eliminates odor. The higher the pipe, the higher the smell goes. It is not necessary to place the pit very far from the house, and the land next to the pit and above it can be used like any other: for beds or a lawn.

  • Cesspool under the toilet. outdoor toilet- frequent construction summer cottages or in private homes. Even if there is a bathroom in the house, the owners often arrange a toilet outside in case of problems with the sewer.

Usually, an outdoor toilet is presented as a place with an unpleasant smell, located far from home. Why is there an odor? Waste accumulates in the pit under the toilet, which releases methane gas. The gas rises. This is what creates the characteristic smell. Cases of methane poisoning and fires have been reported. In addition, under the influence of methane, wood, the main material for the construction of outdoor toilets, is destroyed faster.

Today there is a way to turn the usual view. An outdoor toilet can be located close to the house and not be a source of stench. When building a toilet, it is imperative to take care of ventilation, otherwise the smell will spread both in the toilet cubicle and around it.

There are two ways to ventilate an outdoor toilet:

1. Natural. Based on the natural laws of air movement.

2. Forced. Accelerates the process of removing polluted air with a fan, so it is more efficient. The air in the cabin will be perfectly clean. But for its device, electricity is needed, it must first be brought to the booth in order to connect the fan. In addition, the organization of forced ventilation requires additional material costs - the purchase of a fan.

Both systems involve the construction of an air inlet, exhaust duct, hood located above the cesspool
The easiest way to install ventilation is to install a pipe. The length of the pipe is about 3 meters, the diameter is from 11 cm. A hole needs to be made in the lid above the pit behind the toilet.

The lower end of the pipe is inserted into this hole. If there is a space between the cover and the pipe, it must be covered with sealant or filled with foam. The pipe is set vertically, fastened with clamps to back wall toilet. A protective cap-umbrella is put on the upper end of the pipe. The pipe must be at least 70 cm above the roof of the toilet.

There are two openings in the toilet cubicle:

  • Exhaust - located closer to the ceiling. It is usually cut at the top of the door. With a natural ventilation system, it also performs a second function - a window. When installing forced ventilation in exhaust hole install an exhaust fan.
  • Supply - located in the lower part opposite the exhaust. To prevent mice from entering the booth, for example, a grill is installed on the air inlet.

Ventilation of a cesspool in a private house is a fairly simple matter, it does not require much time and high material costs. At the same time, ventilation effectively eliminates odors and prevents premature destruction of the toilet cubicle.

The absence of a fan pipe and other devices will sooner or later lead to the fact that the ventilation of the sewer will be disturbed and the unpleasant smell will quickly spread throughout all the premises of the house. Regardless of the presence of a centralized or autonomous system, ventilation problems must be solved as quickly as possible. But if the incoming master successfully copes with this in an apartment, the care of a private house falls on the shoulders of the owner. And it is about how to arrange the ventilation of a private house or fix problems with your own hands, it is worth talking in more detail.

The presence in the house of risers with a cross section of more than 50 mm, two or more floors and a large number of plumbing fixtures dictates the need to install a ventilation system. A sharp volley discharge of a large volume of water forms a vacuum in the pipes, as a result of which the siphons are emptied. And it is the absence of a water seal that allows odors to freely enter the room.

Even in the case of equipping the house with pipes big size and a minimal threat of blocking the section with a drain flow, air from the sewer can still appear in the room. The reason is the small size of the siphons. If the sewerage is not used for 3-5 days, the water dries up and a void forms, the water seal valve does not work again and the aromas spread into the house. Troubles can be avoided if there is sewer ventilation in a private house, which is quite easy to do with your own hands. The system may consist of a conventional downpipe or use a vacuum valve. Both options are good, they are used not only in private houses, but also in apartments, and the most effective is the scheme where there is both a fan pipe and a valve that plays the role of the desired addition.

sewerage pipe

The device represents a sequel sewer riser brought out. The principle of operation is simple: warm air always rises up and out, as a result of which a small type of vacuum is created in the pipe system (like draft in a stove) and air is pushed out of the rooms of the house into the sewer, and not vice versa.

Important! The outlet of the fan pipe is carried out through a special shaft, provided for even at the stage of laying the house. But if the device did not work out, then you can bring the pipe system horizontally through the wall on the side.

But to arrange ventilation riser with a do-it-yourself fan pipe correctly, take note of the following recommendations:

  1. The height of the fan pipe cannot be less than 0.5 m from the roof level. In the case of an attic, the length increases to 3-3.5 meters;
  2. The cross section of the hood diameter must be equal to the diameter of the riser pipeline;
  3. If there are a lot of sewer risers, it is allowed to connect the elements in the upper part and equip the system with one fan pipe;
  4. Ventilation cannot be connected sewer type with stove or exhaust general house ventilation;
  5. The best place for pipes is a blank wall of the house. If displayed next to window openings or balcony, the smell can seep into the house. In the absence of a blank wall, the distance between the windows and the outlet of the sewerage pipeline must be at least 4 meters;
  6. If the roof of the house is multi-pitched, the fan pipe should not be led out under the overhang of the slope, the structure can easily break from snow melting;
  7. Equip the top of the hood with a deflector - it is guaranteed to block the ventilation in winter period. Condensation forms on the deflector, which, when frozen, will tightly clog the outlet and the air will go into the rooms.

The hood is made from a pipe from which a common riser is made and is a continuation of the pipeline, bringing it out. The use of cast iron is not desirable, since the material is susceptible to corrosion and there is a risk of complete rusting and falling of the pipe, it is best to make the outlet plastic.

Advice! The fan pipe needs to be insulated. Of course, it all depends on the region and temperature differences. However, even with mild winter frosts, insulation will not interfere in summer cottages, where sewage is used only in the warm season.

Arrangement of sewerage with a vacuum valve

The use of a valve is necessary if it is not possible to install a vent pipe. The system works like this:

  • inside the case there is a spring and a rubber seal;
  • when a vacuum is formed inside the riser (volley discharge of a large volume of water), the spring opens the seal, and air enters the system, equalizing the required pressure;
  • after the spring returns to its place, as a result of which the air from the sewer does not enter the rooms.

The vacuum valve is not an equivalent replacement fan pipe, but copes well with its functions, however, when the water in the siphon dries up, the valve will not prevent the spread of unpleasant odors.

Important! The vacuum valve is always mounted at the top of the riser and only in a heated room.

If it is impossible to install the element on the riser, the installation is made on a pipe running horizontally. Installation rules:

  1. the element is mounted above the point of connection of pipes to the sewerage system of the high drain plumbing fixture;
  2. if the drain is at floor level, the valve is installed at a distance of 35 cm from the height of the floor covering;
  3. it is necessary to ensure free air intake into the vacuum device, as well as access for repair and manual opening (if necessary).

External type ventilation: system arrangement

When equipping the house with an autonomous sewerage system, it is possible to use external ventilation. There are two possible locations:

  • exhaust outlet along wall panels Houses. In practice, this looks like a drain with the end of the pipe above the roof level. The scheme provides for the withdrawal of the structure from the house and fastening to the wall element by means of clamps;
  • installation of pipes on a septic tank - convenient option, since the pipe is located far from the house and completely minimizes the possibility of smell entering the rooms.

External sewer ventilation in a private house is equipped in the absence of a sewer riser, which happens in small buildings or seasonal residences. The use of this method involves the arrangement of a vacuum valve to improve the ventilation system.

Cesspool ventilation: purpose and types

Ventilation pipes are necessary not only to prevent the appearance of smell in the house, but also to balance the pressure within the entire system. However, there is another reason for the mandatory arrangement of ventilation: in the process of decomposition of organic waste, combustible gas is formed and a fire is possible with a large accumulation of matter. To prevent this from happening, ventilation of the cesspool is necessary. The device does not require high costs, but you can do it yourself.

The hood circuit can be equipped extremely simply:

  1. install normal sewer PVC pipe with a cross section of 100 mm;
  2. attach the pipe to the wall at the back;
  3. bring the upper end over the roof of the septic tank to a height of approximately 20 cm;
  4. insulate the pipe from below with tow soaked in bitumen;
  5. cover the exit from debris with a sheet of tin;
  6. concrete the exit shaft.

Advice! For the formation of powerful traction, the top of the pipe is equipped with a deflector.

If cesspool ventilation without a toilet is installed, installation also does not take much time:

  • install a pipe system next to the hatch, the size of which is calculated by the immersion depth and output height;
  • equip the top of the output with a motor to increase traction;
  • cover the exit with a tin sheet.

The sewer hood is ready, and thanks to the presence of a motor, the stench will not be on the site even in the hottest summer days. In addition, there will be no unpleasant odors in the toilet, decomposition vapors will no longer affect the wood, which means that the toilet will last longer.

When building a toilet with a drain pit, it is better to build a toilet away from the pit. It is not difficult to connect structures using a conventional sewer pipeline with a cross section of 100 mm or more. And if you mount a tee, it will be easy to attach a ventilation pipe, which guarantees good ventilation. In any case, the ventilation device is possible in two ways:

  1. a natural variant occurs when pressure increases in drain pit;
  2. forced - air moves through the operation of fans connected to the power supply.

natural ventilation

A vertical pipe is installed, which is needed to remove odors, and the installation is carried out not below the level of filling the pit with sewage, and the top goes beyond the roof.

The cross section of the outlet must be more than 100 mm, the upper end must be at least 70 cm from the roof level. Sealing the pipe and fastening with clamps is mandatory - so you don’t have to worry that the pipe will be blown away during a strong wind.

Forced ventilation

Most effective method but requires electricity. Making a hood with your own hands is easy:

  1. bring electricity to the toilet;
  2. pick up a medium power fan (300 watts is enough);
  3. form a hole for the device, and the fan should work for distillation so that the air does not stagnate in the toilet room;
  4. equip several openings for the influx of fresh air (this can be a regular slot at the threshold).

In this case, the scheme does not provide for the installation of ventilation pipes in the drain pit itself, a fan is enough, which will perfectly expel the air and, along with it, all the unpleasant odors.

Well, to avoid the appearance strong odor in the drain pit, it is enough to purchase biological means for cleaning. These can be powders, tablets or liquids for sewer pits. As you can see, the ventilation device is quite affordable for any owner, and the choice of systems is quite diverse.

Comfort in the country begins with elementary things - plumbing and sewage systems. But for very small areas, it is customary to install a toilet directly connected to the cesspool.

In this case, there is a high probability of an unpleasant odor. In order to get rid of it, a number of measures should be taken.

A typical country toilet design is a small building made of wood or brick. It is located directly above.

During operation, an unpleasant odor is inevitable, since anaerobic processes occur in the cesspool - the decomposition of organic elements under the influence of natural bacteria.

As a result, methane is released, which is the main source of unpleasant odor. Typical circuit organization of a country toilet is shown in the figure.

Photo: design diagram of a country toilet

This is one of best options, since its actual implementation provides the following advantages:

  • waste is removed through a special hole behind the structure;
  • the floor in the room has a solid base - the absence of direct exposure to waste evaporation will significantly increase its service life;
  • the design provides one of the types of natural ventilation.

Ventilation is needed without fail. The appearance of an unpleasant smell in the toilet cubicle is just one of the side factors of its operation. Much more dangerous for a person is the deterioration of the sanitary condition in the room.

If the gas concentration in the booth is high, slight poisoning or deterioration may occur. general condition organism.

Therefore, the ventilation system must be thought out at the stage of the construction project. Without this, it is possible to build a toilet for a summer residence with your own hands, but in the future the comfort of its operation will significantly decrease.


Photo: toilet project for a summer residence

At the same time, its future location is taken into account, the volume of the cesspool and the material for manufacturing the booth are calculated.


Photo: location

After taking into account these factors, you can proceed directly to the consideration of the types of ventilation of the country toilet.

What are the types

Important! On the initial stage design, it should be remembered that the cesspool located under the building is the cause of the smell. Of course, there are certain ways to avoid direct contact with the waste storage site.

To do this, it is enough to place the building a small distance from the pit. After installing a standard toilet with a sewer plastic pipe, it is connected to or a cesspool.


Photo: cesspool located under the building

At the same time, a ventilation pipe is connected using a tee. However, for the practical implementation of this method, it is necessary to run a water pipe to the toilet to flush waste or constantly manually replenish the toilet tank.

This is not always convenient and practical for non-permanent residence. Therefore, it is best to install standard design toilet, in which biological waste is moved into the pit under the influence of gravity without the use of additional mechanisms.

  • natural. Air exchange occurs due to the movement of masses from the toilet to the street;

A photo: forced system ventilation

Each of these methods has its own disadvantages and advantages. However, the installation of any of them is mandatory, since without this the comfort of staying in the country toilet will significantly worsen, and the building will gradually begin to collapse under the influence of methane penetrating into the pores of concrete or the fibers of wooden boards.

Choice certain way depends on financial possibilities and expediency of installation.

Forced

This type of ensuring the timely removal of sewer pit vapors from the premises is the most effective. The essence of its design is integrated approach air exchange of the toilet.

For practical implementation, the main way to prevent the occurrence of an unpleasant odor should be considered.

Cabin ventilation

Almost every toilet located on personal plot, has a small window. It can serve not only to illuminate the room, but when installing a fan, it will perform the function of ventilation.

To do this, you must perform such work.

Connect power to toilet

Often the cable is pulled hanging way. If the cabin is not far from the house, then it is best to stretch the wiring from the attic to the roof of the cabin. In this case, it should be carefully isolated from moisture.

Fan selection and installation

Since the area of ​​\u200b\u200bthe country toilet rarely exceeds 2 m², the choice can be stopped at the very low power model window fan up to 30 watts.

Photo: fan selection

If it will be installed in a window, then it is best to choose square shape devices. Dimensions should be selected according to the size of the window structure.

If for installation it is required to make a hole in the wall, then the shape of the fan will depend on the material of manufacture of the booth.

For brick toilets, a square one is chosen, while in wooden structures it is more convenient to mount round forced exhaust devices. After installation, it is connected to the mains and a test run is carried out.

To ensure the inflow of fresh air, an additional supply hole is made in the wall, the diameter of which must be at least the internal section of the fan.

Important! Installation of forced ventilation into the cesspool is prohibited. This is due to the impossibility of inflowing a large volume of fresh air into its container.

If you install a fan in a vertical pipe leading to the pit, then during its operation a rarefied atmosphere (low pressure relative to the outside pressure) will be created in the sewer pit, the compensation of which will be possible only through the booth.

But often, to prevent the ingress of an unpleasant odor from the pit, the hole in the toilet is closed with a lid, which will prevent the normalization of pressure.

Photo: toilet for a summer residence with a lid

Based on the foregoing, we can summarize the following: the installation of forced ventilation is allowed only in the toilet cubicle, and is prohibited for air exchange in the cesspool.

Natural

It is possible to ensure normal air exchange in the country toilet room in less costly ways. To do this, a natural ventilation system is installed separately for the booth and. A classic example of such a structure is shown in the figure.

Photo: drawing of an outdoor toilet with a cesspool

For the room, you can apply a technology similar to installing a fan. Only instead of forced air exchange, circulation will occur naturally between the inlet and outlet air ducts.

The ventilation of the cesspool occurs with the help of a vertical pipe. It is installed so that the lower part of the pipe is not at the maximum filling level of the pit.

Air flows result from the formation of draft between the opening in the toilet and the pipe. To increase the air exchange rate, it must be at least 110 mm, and its top part rises above the cabin roof by at least 700 mm.

In this case, the formation of normal draft and the timely removal of methane from the pit capacity are guaranteed.

It is best to choose a polymer pipe (PVC), since this material is inert to most aggressive environments.

In addition, it is easy to install and will be able to perform its functions, both in summer and in winter. To prevent a decrease in the inner diameter of the pipe, a deflector is installed on its outer end.

Photo: deflector installation

At negative temperatures moisture may appear on the surface of the pipe, which then freezes. The gradual build-up of ice will lead to a decrease in diameter, which will significantly reduce the volume of passing air.

The design of the deflector will prevent this phenomenon. It is best to choose a model with a weather vane function - this will increase the speed of the air flow due to a decrease in wind pressure in the area of ​​​​the pipe outlet.

What tools and materials do you need to prepare?

Before starting installation ventilation systems an analysis of the state of the toilet should be carried out - the material of its manufacture, the thickness of the walls and the location relative to the cesspool.

After that, you can start the selection necessary tools and accessories for installation.

Forced cabin ventilation

The choice of the description of this method of air exchange is due to its greatest complexity. If you plan to install natural ventilation, then it is enough to select some components from the list of materials and tools.

Materials:

  • plastic pipe with a diameter of 110 mm - 1 r.m.;
  • internal crate for the pipe, which prevents debris from entering the room - 1 pc. Required for air inlet only;
  • steel protective shell, 110 mm inner diameter - 1 pc. Protects the pipe surface from mechanical impact walls during shrinkage of the building;
  • fan - 1 pc;
  • electric wire and switch.

Instruments:

  • perforator ( Brick wall) or drill (wooden wall);
  • fastening material - self-tapping screws, sealant;
  • hacksaw for metal;
  • measuring tool - tape measure, level;
  • insulating tape and pliers - for mounting the fan and connecting it.

This is the best kit with which you can quickly install the ventilation of the toilet.

Natural ventilation of the cesspool

Materials required pvc pipe with a diameter of 110 m. Its height is selected according to the current dimensions of the toilet and the maximum filling level of the cesspool.

In addition to it, it is necessary to purchase a deflector, the mounting diameter of which must match the dimensions of the pipe.

Instruments:

  • bayonet shovel;
  • fastening material - clamps with dowels for fastening the pipe to outer wall toilet.

After selecting all of the above materials and tools, you can proceed with the installation work.

Do-it-yourself step-by-step ventilation device

First, ventilation is installed in the cabin. To do this, the premises are removed foreign objects, if natural light not enough for comfortable work, a temporary lamp is installed.

Cabin ventilation

The exhaust channel should be located in close proximity to the hole leading to the cesspool. The installation height is maximum, but at the same time from the ceiling level to the upper edge of the pipe must be at least 15 mm.

The channel for fresh air is located at the bottom of the wall. For more effective work system, it must be at a minimum height from the floor level.

Important! It is necessary that the distance between the holes be maximum - for this they are placed on opposite walls of the toilet.

Regardless of the material of the wall for fast manufacturing holes, you can first outline its contours, and then, according to the markings obtained, perform drilling.


Photo: marking for drilling

Then, with a little effort, the resulting part is knocked out of the wall. Further, a protective shell is installed in the supply part, inside which a plastic pipe is mounted. A crate is inserted inside it. The edges are treated with a sealant.

Upper air vent made using the same technology. If the fan will be mounted in a window, then its dimensions must match the dimensions of the frame.

With smaller linear parameters of the fan housing, an intermediate mounting housing is made from wooden planks.

After installing the fan, it is connected to the power supply and the switch.

Pit pipe installation

The required length of the ventilation pipe is determined, if necessary, it is cut to the required size with a hacksaw. With the help of a shovel, a small hole is dug in the ground before the start of the cesspool.

Location - behind the back wall of the toilet. Mounting holes for dowels are made on it. Clamps are dismantled, parts with a screw are mounted on the rear wall of the toilet.

Photo: collar

Then the deflector is put on the pipe, which is installed in the hole leading to the cesspool, and fixed with clamps on the walls of the toilet.

The place of its entry into the ground is covered with sand and rammed. This completes the installation of the ventilation of the country toilet.

It will prevent unpleasant odors in the toilet and protect the building from exposure to biowaste gases.
