Fan pipes what it is

Many had to hear from friends familiar to the installation scheme in a private house. It is connected with high-quality toilet ventilation, bathroom, kitchen, whole home, which can be built using a fan pipe.

What is this fan tube, what it can be, how to mount it?

The fan tube is connected to sewage, designed to perform a ventilation, hydraulic function, followed by a roof output. During the operation of the sewer pipeline, gas is accumulated in it. If you do not put the hydraulic barrier, they will penetrate the living room that is dangerous for the life of the inhabitants of the apartment. In addition, the unpleasant odor will spread throughout the house.

It can be arbitrary length, form, depending on the place of installation, the size of the sewage highway. This part of the exhaust system can be straight, angular, placed in horizontal, vertical directions.

In order to avoid embossing odors in the home, it is necessary to make high-quality. In such cases, it helps for the manufacture of which plastic is most often used. However, no elements of metallic origin were completely outlined. Today, many in their homes use cast-iron, less often. Metal does not want to give up its positions.

Possible schemes

The gasket, the replacement of sewage risers does not allow errors in the process of planning, installation of the system, otherwise the residential premises will be filled with an unpleasant odor. So that this does not happen, in a private house you need to choose the right tube scheme.

There are 2 installation schemes of exhaust systems:

  1. Horizontal.
    Accordingly, this scheme, the output of the fan tube must be carried out through the hole in the wall, and not through the roof. Such a scheme can be used in private construction, if it is impossible to make out the roof. The final outlet is closed with a grid, not a deflector.
  2. Vertical.
    With this scheme of the fan pipe in a private house, the riser comes out through the roof.

There are three types of vertical yield in the atmosphere:

  • the output at an angle of 90⁰. It is necessary to make two taps at the angles of 90⁰, after which it will be released vertically through the roof;
  • conclusion under the slope of 45⁰. For the direct yield of the riser through the roof, it is necessary to make a branch from the main riser first at first 45 degrees, and then - by 135 degrees;
  • the usual output of the vertical type, which immediately continues to the roof and will come out through it.

Important! The installation diagram of the ventilation in a private house must be correct, that is, in accordance with the appropriate diameter and in the right place, to anticipate the presence of a reverse, overlapping overflow of feces.

Use cast iron elements

For several decades, the arrangement of exhaust channels occurred using cast iron risers. Today you can meet cast-iron fan pipes. And in vain, because using risers from this material, you can be confident as exhaust and ventilation channels. Possess a number of advantages.

They differ:

  • strength. The rigidity, the alloy density contributes to the safe functioning that you can buy in a construction store. They are used in the construction of private, multi-storey houses;
  • long service life. This is due to high wear resistance that helps for many years to maintain excellent specifications;
  • resistant to the effects of mechanical type. They are not afraid of random blows, damage, large loads.

Minuses:

  • propensity to corrosion processes;
  • the complexity of transportation;
  • high weight;
  • high price.

Replacing, replacing old cast iron risers, you need to dismantle the current system. It is difficult to do this if the sewage, exhaust highway is placed in a hard-to-reach place. How to disassemble the fan cast iron pipe for the toilet? It is difficult to implement this procedure if there is a pass with cement, aluminum or sulfur to connect the risers.

First, it is necessary to dismantle the details that are located on the riser. To do this, stock chisel, a hammer with a plastic or rubber head. When you hit the chisel with iron hammer, the pieces of metal are sharply bouncing from the pipe, they can fall into the riser, as the cast iron is a very fragile alloy.

After performing all the preparatory work, proceed with the removal of a cast-iron fan or sewer riser:

  1. After the destruction of this element of the system, gradually approach the cross, leaving 30-35 cm almost broken part.
  2. Using the left piece smoothly loosen it. If it does not help, then the chisel start to delete the package, it is again overwhelming, after which to get the remaining fragment.
  3. If the system is sealing gray, then it is necessary to take a soldering lamp or gas burner and start heating the package. Before that, it is necessary to cover the furniture, the walls to cover the furniture, the walls to damage them. It is desirable to perform this work together, since one must remove the heated viscous sulfur.
  4. After removing a certain amount of preheated mass, get the residue of an unnecessary part of the part.

A variant is possible when you can cut off the rest of the highway to the terminal itself. Such a procedure will provide not only a neat cut, and a quick, comfortable docking new with an old cast iron riser.

Important! The cast-iron fan tube can be used in any extreme situations. This means that such a system will function normally in conditions of a wide temperature range at elevated pressure.

Works with cast-iron fans or sewage pipes, including their drilling, you need to be carried out as carefully. This is due to the increased fragility of the metal.

For a long period of operation, as a result of corrosion processes, cast-iron sewage risers become unattractive. Therefore, they need to be refreed. Cast-iron pipe in the toilet?

For painting use acrylic, water-dispersion paint. The shade may be the most diverse.

Some owners refresh the cast-iron risers with oil paints. Before painting, you need to get rid of rust, old exfoliating paint, unnecessary garbage, dirt. Only after such preparation can be stacked. Painted, renovated sewage highway will serve not yet one year.

Application of plastic structures

In private houses, with the system of systems on the removal of air and various kinds of odors, they use predominantly plastic fan pipes. They can be round or.

Rims used as fan are produced different sizes. When adjusting the system of exhaust or supply ventilation, fan plastic pipes with a diameter of 50 to 110 mm and a length of 3-4 meters are in demand.

If a plastic fadah tube cracked in the overlap, then you need to replace it. Repair of this detail of the exhaust or ventilation highway will not bring the desired result.

When implementing such a procedure, a sequence of work should be followed:

  • using the perforator around the rising, expand the diameter of the hole (at least 2 times);
  • bulgarian cut the cracked element of the system around the middle of the height to make it convenient to extract both pieces;
  • get the cracked items and put a new riser in their place;
  • close the hole around the installed element of exhaust ventilation as below in the ceiling and in the upper plane of the overlap.

It must be said about the presence of flexible plastic fan pipes. To connect them with a solid area of \u200b\u200bthe system, it is recommended to use rubber rings for sealing. For better entry into the socket, complete tightness before mounting, they need to be covered with silicone. When attaching such a plot to the wall, clamps from metal, characterized by increased reliability, are used.

Important! Although for high-quality sealing silicone - the perfect substance, it should be remembered that with the next dismantling to remove it will have to make a lot of effort.

Today, plastic risers can be purchased in any construction market or shop.

Dimensions

A separate part called Fan pipe regardless of the size - does not exist.

This design includes:

  • ordinary tee;
  • lid or grille;
  • one or more pipes;
  • protective valve.

The dimensions of the fan pipes for sewerage, as well as for the toilet bowl, depend on the specific conditions for their operation.

The rules should be followed:

  • you can use parts from any materials;
  • pipe size for exhaust riser including length can be different.

Today, plastic fan pipes are most popular with diameters from 110 to 50 mm, regardless of other linear dimensions (length).

With the help of a fan tube 110x45 Ani Plast W4220, which can be of different sizes, conveniently connect the sewer with the release of the toilet. Such a detail seems to gluit the toilet with the sewage rummer, which will ensure the absence of the leakage of the bathroom. The size of the fan tube for the toilet depends on the diameters of the drain, sewer riser, from the distance of these elements to the wall or ceiling.

The diameter of the part should be such that the maximum possible sewage streams do not interfere with its normal functioning. Sometimes ventilation and sewage are constructed from risers of different diameters. Then it is necessary to enjoy a special adapter.

There is a directory where you can select the necessary parameters of parts to arrange an exhaust system.

Important! The ideal option for hooding is a place where the internal and external sewage is connected.

Ventilation of the fan pipe

The current construction regulations say that in one-story houses it is not necessary to install ventilation, because in such dwellings one-time settlements are small. Buildings in two or more floors should be equipped with such systems. This is due to the fact that with the help of such risers, communication with the environment is due, and therefore ventilation processes occur.

Many are asked: "Is it possible to bring a fan pipe to ventilation? And if so, how to connect the fan tube to ventilation? " We will give these and other questions a detailed answer.

When installing the fan pipe, it can be simply necessary to withdraw it, which is most often done. To carry out such a procedure, you must first build the ventilation channel.

It is necessary to foresee the setting of the check valve.

His appointment:

  • prevents reverse return of drain flows;
  • prevents rodents in the sewer and room;
  • adjusts the variant of the sewer pipe with an incorrectly mounted slope;
  • restrictions in the toilet of mechanical impurities.

The principle of operation of the device is simple: after water comes out of the drain tank, it works and the liquid enters the sewer system. With the valve closed, unpleasant odors are not applied from the toilet and sewage, since the device is fully hermetically.

Important! Install the check valve immediately after the toilet.

Although everyone is trying to correctly mount the exhaust system, yet in our homes and apartments you can feel the unpleasant odor from the sewer system.

Sometimes smells with a fan pipe pool into ventilation, as these two channels are located nearby. To get rid of unpleasant flavors, it is necessary to put the aerator on the upper end. Thanks to this vacuum valve, the system will function perfectly.

Conclusion to the roof

Do not everyone know how to bring ventilation to the roof. It is necessary to do this, because the ventilation system will end in the attic can not. Fan tube must have a roof exit, so that there is a connection with the street, the atmosphere. If the sewer collector is led into the attic, then all unpleasant odors will be concentrated there. When the hood does not go on the roof, the mold will begin to appear in the attic as a result of increasing humidity in the attic room, which will bring a lot of harm to whole dwelling. The fan tube is mounted both on the roof of a multi-storey house and one-storey.

What to do when the fan pipe on the roof freezes? So that it does not froze on the roof, it is necessary to make insulation around. The cause of freezing is the formation of condensate, since warm air has a property to climb up. As a result, the frost of the walls of the ice, which can lead to the overlapping of the exhaust lumen and stop the functioning of the whole system.

Warm rolled heat insulators or "shell" that should be securely secured.

In some cases, it is impossible to derive the fan pipe to the roof. This is not a problem because you can use a horizontal mounting scheme of the exhaust system. The end of the ventilation system will be not on the roof, and will be removed through the wall to the air.

You can buy a fan pipe on the roof in a construction supermarket.

Important! Regardless of how the fan tube is derived - on the roof or through the wall, the system requires a check valve.

In order for ventilation systems to function for a long time and efficiently, during the installation of highways, you need to adhere to the aforementioned norms and rules. Only then your home will not fill unpleasant odors, and the sailing of fresh air will constantly be felt.

On the ventilation of concrete septic

For sewage effluents on its territory, each owner tries to make 2 chamber concrete septic. These containers should be ventilated not only to eliminate unpleasant odors. If we correctly design and make the ventilation system in the septic, then you will make your family living, residents of neighboring homes safe, comfortable, pleasant. You need to take care not only about yourself, but also respect the neighbors.

Such a structure is the habitat of bacteria that are able to quickly recycle waste of organic origin coming from the sewer system. As a result, dirty estates turn into clean water and Il. Such a biologically-chemical process is accompanied by the release of a large amount of gas, which not only smells unpleasant, but may cause an explosion in the event of a sparks on him. Conclusion: High-quality ventilation of a two-chamber concrete septica without a fan pipe is impossible. For the full functioning of the usual Septic, it is also necessary to make ventilation.

Before talking about the fan pipes, you need to know if a fan pipe is needed in a private house. The appointment of fan pipes is simply needed - they are needed to connect the sewage to the atmosphere, due to which the ventilation of the system is ensured. In addition, the fan tube levels the pressure in the sewage pipeline, so the resulting vacuum does not lead to the emptying of the siphones.

The need to install fan pipes directly depends on the volume of the simultaneous drain into the sewer - if it is large enough, then the pipe is uniquely needed. However, this item will be considered further. In this article, we will talk about what a fan tube is needed in the sewering of a private house.

Functions of the fan pipe

In any sewer pipeline, there is always air, but during plum it begins to go into the atmosphere and pulls water from the hydraulic assets. The absence of a water shutter always causes the characteristic sealing smell into the room.

Fan tube in a private house at the same time serves three goals:

  • Gas output from the pipes of the sewer system;
  • Maintaining the necessary pressure in the pipes, which allows you to simultaneously merge a large amount of drainage without risk to run an unpleasant smell into the house;
  • Forms the required vacation vacation.


Mount the fan tube is required if the following conditions are followed:

  • The diameter of the sewering riser is less than 50 mm;
  • Each floor has a separate bathroom connected to a single sewer system;
  • In the sewer, water is drained from the connected pool;
  • Right near the building is an autonomous sewer system (for example, a cleansing septic).

Device of fan sewage pipes

By installing the fan tube in a private house, you need to ensure that the following rules were followed:

  • The diameter of the fan pipe should always coincide with the sizes of the riser;
  • Fan tube and ventilation from sewage pipes are excreted on the roof so that it is located at maximum distance from the windows and balconies;
  • It is best to have a fan pipe at a distance of 30-50 cm from the skate - as practice shows, such a height is enough for a normal air removal from the system;
  • Fan pipes are set to compensate for one-time drains, so their magnitude needs to be accurate even before commissioning the system;
  • For the bathroom, 110 mm riser is used, so the pipe diameter cannot be less than 110 mm;
  • For runoff from the bath, 50 mm pipes are usually used, and the fan tube must have the same bandwidth.

Rules for installing fan pipes

When adjusting the system with the connection of the fan tube, such rules must be followed:

  • Selecting the material for the fan tube, you need to ensure that the diameter of the selected pipes coincides with the riser diameter;
  • The top edge of the fan tube must be at such a point where the air will be faster to mix with the atmosphere (for example, the attic room for this is not suitable);
  • The first segments of the sewer system must be in the heated part of the room;
  • The last section of the pipeline is installed where there is no heating - the movement of contaminated air masses is provided by temperature differences and pressure changes.


There is another moment, which is worth considering separately, since it has no direct relationship to fan pipes, but directly refers to the operation of the sewage. When installing various plumbing devices, the following situation arises - the volume of siffones does not correspond to the characteristics of plumbing.

All this leads to a simple result: in small siphons, water dries too fast, and the smell of nothing interferes into the room, and the plums of large siphones are inexpedient, and the fan pipes with a considerable probability simply will not be able to compensate it.

Output of ventilation pipes on the roof

The sewer system is used to lead the effluent outside the building. So that the sewage can fully function, it must be equipped with ventilation - and for this, risers with fan pipes are installed. Important moment: Fan pipes for external sewage can not be equipped with various exhaust devices, such as deflectors or flugames.

If there are several risers in the building, it will be much easier to combine them into one system and output through one ventilation channel ending with the fan tube. The design provides for a consistent installation of a skewer tee, a 45-degree knee, another knee and direct tee. Well, then the ventilation pipe is displayed on the roof, where she and place.


There are several simple rules for the output of the fan pipe to the roof:

  1. The fan tube is set to about half a meter above the roof skate - but it is relevant only for unused roofs. On the roof, where there is a summer terrace or garden, the fan tube will have to raise three meters above the roof level.
  2. The sewer system, which includes more than one riser, is usually combined by means of a single ventilation pipe.
  3. Holding a place to withdraw the fan tube into the atmosphere, it is necessary to select it in such a way that the distance from the nearest windows is at least 4 m.
  4. To remove the fan pipeline under the cornice roof is extremely undesirable - the design with very high probability will be damaged by atmospheric precipitation. See also: "".

Installation of the check valve in a private house

In order for the fanner pipeline to function efficiently, it must be additionally equipped with a check valve that allows you to solve a number of problems:

  • Compensation made by mounting errors in determining the magnitude of the liner of the pipeline, due to which the wastewater deposited into the system can be returned to plumbing devices;
  • Preventing from entering into the sewer pipeline of various foreign objects, rodents and other livelies.


The functioning of the check valve is reduced to the following points:

  • Wastewater, lowered from plumbing devices, easily enter the system through the automatically opens the valve cover;
  • The rest of the time when the descent of wastewater is not carried out into the system, the valve is closed;
  • Increased pressure in the pipeline or its clogging will not be the reason for the deposit into the room - in the opposite direction the valve does not open.

The check valve can be mounted on the outer and on the inside of the sewer system. Before installing the valve in the system you need to pre-clean and degrease the pipes so that the element is well in its place.


When the preparation is completed, the valve by the desired side is started into the system, and its petals are strung in the direction of sanitary devices. When preparing pipes to the installation of the valve, various types of lubricants cannot be used - the design at the time of installation should be dried.

Conclusion

Fan tube in a private house allows you to solve a number of problems associated with the work of the sewer system. The installation of the fan tube and the check valve is not particularly difficult, and if the sewage is equipped with their own hands, then these elements will be able to install themselves.

Creating a high-quality sewage system in a private house allows you to exclude problems with unpleasant smells accompanying the work of sanitary equipment. Therefore, the installed phase of sewage in the private house will be an integral element of the household network.

Functional features

With a sharp disclosure of a large volume of water in a small section pipeline, there is often damage to pipes, a hydraulic blow. Therefore, the fan tube for sewage in a private house is an integral element of internal engineering networks. Due to its use, the sewage in the private house has an additional air flow, and additionally design eliminates pressure drops.

The apartment building without a fan pipe is capable of functioning only with the installation of a shower cabin, where water consumption is small. The standard bathroom refers to peak expenditures, during the discharge of wastewater from a sanitary device, the pipe cross section is maximally filled, the inflow of fresh air becomes minimal.

A similar situation in homes without a fan pipe provokes flooding of the first floors of the building at the time of mass drain of water. The installation of an additional design will allow to extend the life cycle of the sewer riser, especially plastic, and also lines the work of the ventilation in the sewer pipes.

Many masters advise to narrow the diameter of the pipeline, motivating the lack of costs in the attic of the house. Regulatory documents, as well as the experience of operating engineering networks in the private sector and apartment buildings, forced to abandon such manipulations.

Sewer pipelines from the sanitary node where the toilet is installed are dictating. The drain pipe of the toiletz has a cross section of 110 mm, the riser of domestic sewage is required to repeat its size or be greater. If there are two toilet and two baths on the riser, it is necessary to conduct a hydraulic calculation of the bandwidth.

Constructive location schemes

Modern solutions of the sewage network based on polymer pipes allow you to significantly extend the service life of the system and simplify installation work. Sewerage in a private house without a fan pipe remains quite working, especially in homes with a small number of instruments and people, the standard system copes with flow rate.

An unpleasant smell appears at the moments of a large load when most of the devices are triggered at one moment. In such situations, many owners establish additional aerators - ventilation valves, they compensate for the lack of air in the system. The installation of such equipment occurs at a level of 1-2.5 meters from the level of pure floor.

The installed the status complex will make a number of advantages:

  • Working and independent to remove odors from the risers.
  • Creating a qualitative limitation of water influx, with normalization of air pressure inside.
  • Providing functionality for several bathrooms located at different levels in a private house.

Such items will allow to build the required riser, taking into account high-quality ventilation and ensuring the durability of functionality. The resulting sewage will ensure the use of several full-fledged bathrooms.

This is relevant when a private house has independent and multi-level options for placing wastewater removal. The output in this situation is one - the wizard system can be mounted with one fan riser, the exhaust part of which will be combined. But the diameter of this pipeline is obliged to respond to the cross section of the working riser or be more than 50 mm.

Materials of pipes

Fan pipe for sewage in a private house in two, three or four floors, a decisive factor, in the absence of hydraulic shutters of the upper sanitary devices, it is necessary to count on additional load. With this calculation, it is necessary to take into account the second consumption from the instruments, the cross section of the pipeline, local resistance and pipe material.

Depending on the temperature of the assigned water, as well as the requirements for the working strength of pipelines, the specialists are selected and mount the following pipes:

  • Plastic, modern polymer or metal-plastic for the device of the samotane lines.
  • Plastic, metal-plastic pipes of low-suck series for pressure pipelines.

Constructive solutions for installation and output of the fan pipe on the roof

When designing a home or reconstruction, it is important to properly select the location of the system and individual sewage sites. Only in this case, the fan of the sewage in the private house will function, regardless of the weather outside the window.

If we are talking about a large temperature difference within the building and beyond, especially when the house is used all year round, and the climate has a long period of negative temperature, then the wizard install the node inside the building or connect electrical heating.

Machine installation should be inside the building, withdrawing a riser above the roofing level. This will eliminate freezing problems and will give reason to ensure the necessary functionality, regardless of weather conditions. In this case, the sewage will provide a number of regulatory requirements:

  • Removal of unpleasant odor.
  • Condensate and freezing of pipes are excluded.
  • Full functionality without hydraulic impact at the time of peak costs.

In a situation where the owners of the house do not have the necessary free space for the device of the fan node indoors, experts advise to install a node to the outer wall, sew the design, insulate the mineral wool. An additional source of heat in this design is the thermal cable.

Functional sewage system without fan nodes

The sewage in a private house without a fan pipe is performed in one-storey buildings that have an operated basement, but the installation of the toilet and the bathroom passes only on the first floor not far from the riser and release into the outer sewer network.

The flow rate of the washbasin or washing of the house system in this case is not dictating, such a number of wastewater from sanitary devices occurs irregularly and affect the operation of the system is not capable.

A private house is often supplied with grease traps, the equipment reduces the concentration of fats and organic matter in wastewater. Installing such equipment implies regular flushing of hot water pipes. Air valves will help compensate for the lack of oxygen.

The valve output is connected to the main pipeline from the sink of the shaped parts, the difference of marks protects the equipment from flooding during the washing of the pipeline.

The construction of any private house does not work out without a device of engineering communications. In particular, we are talking about the sewer system. When it is not necessary to forget about device of fan riser. Next, consider what it is and why this is needed. The article will also provide a brief instruction on the installation of the riser, recommendations of specialists, regulatory requirements, and also described an alternative and the most common errors in operation.

Purpose

Fan riser in a private house - Part of the pipe, departing from the sewer central riser. She comes out of the facilities and takes unpleasant odors from the house. The absence of this element leads to a violation of the hydraulic assembly. As a result, an unpleasant smell appears in the room. Cleaning sewage In such cases, it will not help get rid of it.

In each plumbing device, a discharge pipe with a knee is provided. In bending there is water, acting as a hydraulic assembly. It prevents the penetration of the unpleasant smell into the room. When resetting the runoff, discharge occurs. Corvented air from the street, which ensures normalization of pressure. Due to this, the smells do not penetrate the room.

Always whether you need a fanker? Without this device you can do in small structures with one bathroom. If in the house 2 toilet or 2 bathrooms needed.

Important factors

Fan riser is equipped if:

  • The building is two-story, and there is a bathroom on each floor.
  • Diameter of sewer flow 50 mm.
  • The adjacent area is equipped with a swimming pool or other object for which regular water reset in a large volume is required.
  • The house mounted hermetic septic septication.

Development of the installation plan

To fix correctly fan tube for sewageIt is necessary at the design stage to take into account the following factors:

  • The pipe should go to the side, into which evaporations are discharged due to air flows.
  • Tube removal performs to if this is not possible, installation is made through the wall.

Elements

Ventilation sewer riser includes:

  • Pipes.
  • Ventilation channels.
  • Fitting.
  • Connecting elements.

Principles of installation

How to install a loaf for home? It is worth saying that the installation planning must be carried out simultaneously with the design of internal sewage. To increase the efficiency of the riser, it is necessary to avoid a large number of angles and bends.

Perfect position fan pipe for sewage It is strictly vertical. It is displayed through the inter-storey floors on the attic and then on the roof. But in practice, unfortunately, it is not always possible to implement such a project.

Usually in private homes are used additional connecting elements. For example, an auxiliary pipe can be connected to the main fan riser, an individual pipe is output in one distance from sewage risers, etc.

The key task at the system design phase is the correct calculation of the diameter of the pipe for the discharge. It can not be more than the size of the sewer pipe (110 mm). Ideally, the diameter must correspond to the magnitude and central riser, and the nozzle connecting the inner and outer part of the system.

When designing, special attention should be paid to the placement of the riser. It should not be near the climatic equipment, as well as the removal of the burning of the heating boiler.

Installation of fan riser No special difficulties. However, some nuances should be considered.

For central sewage, it is advisable to use the pipe 110 mm. The same diameter should be at ventilation riser. Typically used plastic pipes. If the system consists of elements made from different materials (for example, a plastic riser, and the sewage is cast iron), rubber adapters should be used.

To connect several risers, angles are 45 or 135 degrees. Plots located horizontally should be laid with a slight inclination (0.02%) towards the outlet of the drain. If you need to change the angle, a special removal is used with a turn of 135 degrees.

Replacing fixture

The need to replace the fan riser or a separate part can be associated with different reasons. For example, some owners with overhaul update all engineering systems in the house.

Replacing the riser is carried out by the same principle that the repair of sewage. At the same time, a number of conditions must be observed:

  • During work in the premises should be organized
  • Replacing elements is carried out in the respirator and gloves (rubber).
  • Upon completion of the work, it is necessary to check the tightness of the compounds.

If necessary, simultaneously with the replacement of the riser can also be conducted cleaning sewage.

Regulatory requirements

There are several indicators that should be considered when installing the fan riser:

  • In the output of the pipe on the roof, the distance to the roof should be at least 30 cm.
  • If the house is provided by the attic (attic), the length of the riser is not less than 3 m.
  • There should be a distance of 4 m between the pipe and loggia or window opening.
  • The fans should be installed in a heated room. If it is difficult, the pipe must be inspired.
  • Through the chimney, it is impossible to output the riser.
  • On the top of the pipe outside the protective elements from birds, insects and precipitation are mounted.

Common mistakes

Despite the relative ease of installation of the fan system, there are a number of rules whose violation can lead to negative consequences.

For example, some owners of private houses cut a pipe on an attic room. As a result, unpleasant smells begin to fill it with (or attic), and subsequently penetrate the house. Accordingly, the system of the system loses any meaning.

Another error is the installation of the pipe along the outer wall. In this case, the likelihood of condensation is high.

Some household owners set an additional device - roofing aerator. It provides an improvement in thrust. Meanwhile, the installation of this element is not always appropriate. As a rule, the outflow of sewage evaporation slows down. As a result, again, unpleasant odors begin to penetrate the premises.

Alternative option

As a vacuum stands as it. It is mounted at the end of the riser directly in the house.

The valve is a small device made in the form of a flush. Under certain pressure, it passes the air inside the sewage, but it does not release it back. At first glance, this is a fairly effective solution to the problem. However, there are several important nuances.

The diameter of the air holes, actually several times less than the size of the riser. Immediately there are doubts about the efficiency of the device. As practice shows, in an apartment building with a sufficiently high load on the sewer system of one such device is not enough - you need at least several. Accordingly, it is necessary to highlight enough space to install at least 4-5 valves.

Another problem is hidden in the design of the device. The valve will be effective if the gasket located inside it is strictly horizontally. Even with a slight distortion, the valve is jammed in some position (closed or open). In any case, it will entail unpleasant consequences.

Principle of operation of the valve

Inside the device there is a special spring with a small resistance. Tightness provides rubber sealing gasket. The principle of operation of the vacuum valve is as follows:

  • Locks of sewage pass on the riser and provide permission in the system.
  • The valve shutter opens.
  • Air is absorbed from the siphon and passes into the sewer network. Due to this, the vacation is quenched.
  • After the pressure stabilized, the spring mechanism begins to operate. At the expense of it, the shutter overlaps, and the air does not enter the room.

What should pay attention to?

It should be said that the installation can not be called a full alternative to fan riser. The fact is that the device quickly clogs. When the siphon is dried, the efficiency of gases is significantly reduced.

If you set the return valve to the riser is not possible, it can be mounted on another horizontal part of the pipe suitable for the riser.

SNIP

The problem of unpleasant odors in the room occurs not only in the absence of a fan riser. The quality of sanitary equipment is of great importance. When choosing it, it is necessary to check the presence of a hydraulic shutter. Modern equipment in most cases is equipped with this device. However, there are models without it.

In addition, in the Russian Federation there is a special regulatory document SNiP. It contains factors, in the presence of which the installation of fan risers is required.

Consequences of lack or improper installation

If we talk like simple words, the fans are ventilation. The key task is to ensure air inflows into the sewer system. This, in turn, provides the ability of the flow to quickly cope with the movement of the volume and eliminate unpleasant odors.

In apartment buildings without a fan riser, it is impossible to do. Housing and communal services are very negative about any work affecting this part of the sewer system, even if the housing owner wants to install a vacuum valve instead of a pipe. Above, we have already considered the disadvantages of such a device. Do not insist on your own and redo the system. Otherwise, serious problems will arise. They will spoil the life of all neighbors whose apartments are located along this riser. An unpleasant smell will spread very quickly.

Especially dangerous situations when the plug is put on the fan riser. In this case, the unpleasant smell will definitely go to the apartment, because it has nowhere to go. It will penetrate into the room, it will be through the pipes and parts of the pipes, suitable for plumbing equipment, sinks.

Often the situation is aggravated by the fact that the flushing in the toilet is entails a large volume of water into the system. She, acting as a piston, pulls the air. As a result, the pressure is disturbed. To stabilize it, the suction of water shutters from siphons of shells, bathtubs, washing in the kitchen begins. In the absence of water in the knees, unpleasant smells are freely penetrated into the premises.

Another problem is to clog the sewer network. Frequent pollution becomes the result of the absence of a full air tributary. The system will stop cope with its functions, and the owner of the room will have very frequent sewage cleaning.

The owner of a private house is definitely not experiencing those restrictions that burden the tenants of apartment buildings. It can choose, install a fan tube or not, whether the vacuum valves use instead. However, not all owners of private houses have the necessary skills and have the necessary tools.

To prevent probable problems, it is advisable to entrust the setting of the riser, and the best sewage system of professionals. Specialists will develop a project taking into account the wishes of the customer and the features of the structure. In addition, they will choose the most appropriate materials for the installation of the system.

Installation, of course, can be carried out independently. In this case, it is advisable to pre-consult with acquaintances that have already mounted the system. If plastic elements are used, one person will fully cope with the installation. The weight of pipes, even long enough small. To install cast iron elements, you will have to use someone help. In this case, the installation can be carried out together.

Conclusion

The sewage system is considered one of the main engineering networks in the house. Its effective functioning provides comfortable accommodation regardless of the time of year.

It should be said that systems can be carried out using not only plastic, but also pig-iron pipes. They apply, as a rule, in areas with harsh climatic conditions. In the regions with a mild climate, it is more expedient to use plastic pipes. If necessary, they can be insulated with any suitable material. Building stores present a wide range of various insulation. The most common material for protecting pipes is the Ministry of Service. When using insulation, it is important to provide for protection against wetting.

When applying a fan riser, it is important to comply with the standards set by SNiP. It will not very aesthetically look a pipe next to the window. In addition, the further it will be located from the opening, the less likely the probability of the penetration of smells into the room.

After installing the standing, it is necessary to periodically check its condition. As practice shows, plastic pipes serve quite a long time, but there is always a probability of clogging. Check can be carried out pretty quickly. The whole system is collapsible, you can easily disconnect the items.

Fan tube is a component of sewage, without which it is impossible to equip the bathroom. It is designed to communicate the sewage riser with the atmosphere, prevents the formation of wastewater and the appearance of an unpleasant smell in the bathroom.

A fan tube installed in the toilet room prevents the appearance of discharge in the sewer system and ensures uninterrupted operation of water shutters. In our material we will deal with what fan pipes are, as well as tell about the rules of their installation.

Fan pipes are classified according to the structural material used in the manufacture of products.

Classification divides fan tubes for 2 types:

  • metal;
  • plastic.

Metal (cast-iron) option can be mounted in the sewer system made of similar material. Plastic products can be installed both in the plastic and the cast iron pipeline.

When mounting the element from plastic, a flexible sewer fan tube is obtained, a monolithic knee or a compact adapter. Cast iron products do not have flexibility and do not differ in variety of forms.

What is the fan tube?

According to the construction regulations current today, the process of building a single-storey house sewage system can be performed without a fan pipe. This is due to a slight amount of one-time drain.

If the building consists of two or more floors or housing is equipped with several bathrooms, then in order to ensure stable pressure in the sewage system, a fan tube is required. This element binds a riser with an atmosphere, supporting stable atmospheric pressure even in the case of a volumetric emission of water from a toilet tank, which provokes a vacuum in the discharge line.

According to the accepted construction standards, in one-storey building with one bathroom, the minimum amount of effluent, so the installation of the fan tube in the bathroom is optional

If several toilet rooms are equipped in the residential room, then the situation changes dramatically and the fan tube installed on the toilet is a vital necessity.

This rule applies in the following cases:

  • the house has 2 and more levels that are equipped with a sewage system and water supply;
  • the diameter of the cross section of the sewage is 50 mm;
  • inside the building there is a swimming pool or water equipment that descends considerable amount of effluent into the sewage;
  • septic typically located to the house, which can cause a sufficiently unpleasant smell.

In the above cases, the vacuum without a fan tube can lead to a rapid emptying of siphones under a toilet or sink, which will provide direct contact "atmosphere" of septicity with a microclimate of the room.

Thus, the installation of the fan product in the sewer system provides stable pressure in the discharge pipeline and retains the integrity of water drains in siphons under special waste holes that cut off the unpleasant aroma of septic stems from home microclimate.

Construction of a system of sewage and ventilation with fan pipes is rational in the following cases:

  • when installing a sewage riser in a private house with a diameter of 50 mm;
  • if there are two or more floors in the house, each of which has a bathroom;
  • in the private house there are tap equipment, such as a pool generating powerful water drains;
  • the autonomous sewage system is located next to the residential house.

Toilet bowls with direct (vertical) release to the floor are mounted using special spare parts. The sewage isolation is usually located under the floors, and the pipes do not require the presence of walls and partitions

Installation of plumbing with horizontal release

Connecting toilet models with direct (horizontal to the floor) release is relevant for the conditions in our country. This is due to the fact that the bathroom is tied to a certain wall of the toilet room due to the specific wiring of sewage pipes in standard houses of Russia.

Since the release in these models is directed back, it is in the back of the product. The outlet is attached to the pipe using a sealing cuff.

When installing, you should pay special attention to the consolidation of sanitary equipment to the floor of the bathroom. The legs of a plumbing bowl with a horizontal release have specially done holes intended for reliable fixation of the toilet to the floor.

Connecting plumbing equipment with direct release ends with the installation process, during which screws and dowels are used. The mount must be done carefully, since in the case of strong "reaching" the screw can be damaged by the integrity of the Sanfayans surface.

Installation of sanitary equipment with oblique release

The process of installing and connecting sanitary equipment with oblique release is performed in stages:

  1. Before connecting plumbing to the sewer system, the release of the device with the grooves located inside should be lubricated with a mixture of turkey with a oliff (or sealant).
  2. From above, it is necessary to carefully wind the resin strand. The tip of the throttle with a length of 0.5 cm should remain free, since the ends of the strands can enter the hole and provoke the occurrence of clogging.
  3. The wrapped resin strand is lubricated by Surikov.

Then the installation of the toilet is performed, in the process of which the outlet process is fixed in the circular of the sewage pipe.
