Many of the inhabitants of the upper floors of high spirits were asked why the sewage riser is needed where no one, in theory, does not live? All of them attend thoughts to remove it and to arrange a liquid, for example, shelves or mount installation in it. And the truth is why the useful area disappears that you can use for your needs? We will deal with this question in this article, in which we will find out with the site with the site, why do you need a fanker, what does his disassembly threaten and is there an alternative that is able to replace it?

Fan stand: appointment and consequences of his absence

If you speak short, then the fan is nothing like ventilation. Its main task is to ensure air inflows inside the sewer system, which ensures its ability to quickly cope with the transport of a large volume of water and removing unpleasant odors. Let's say directly - the relevant services of the housing service negatively refer to the issue of removing this part of the riser, even if it is replaced by its air valve. Why? Everything is simple - his absence entails a lot of problems that begin to pour one after another on their head. And although these troubles can be counted on the fingers, they can make the lives of residents of the altitude house unbearable. These problems include the following.

Now decide whether a fanker is needed in your apartment or can better accept it with his presence? By the way, if you are a resident of a private house, then you should not think that you will not have such problems. It should be understood that any sizes of the sewage system and how correctly it is assembled, the fanner is its integral part, and it simply does not exist with a full replacement. Think about it at your leisure, and I will still tell you about one alternative, which allegedly allows you to remove the sewer system.

Features of the device of the fan riser and the nuances of its installation, see the video.

Air valve: all for and against such a replacement of fan riser

What is an air valve for sewage? This is a small device made on the basis of the end-stub. Two valves are embedded in it, which at a certain effort are imparted into the air inside the sewage system, and back it is not released. In principle, this is what you need to get rid of the consequences of the absence of a fan pipe if there are not a few "but".

1. In fact, the diameter of the inlets of the air valve times in five, if not ten less than the diameter of the riser. Immediately grant suspicions. Does this device cope with your tasks? Practice has shown that in apartment buildings (with their sewer loads) of this device is not enough. Now think how much the places need to place at least the heels of such devices in your niche? Everything is right, nothing will remain from it - it can be said that you will change the sewer on the soap.
2. The design of this valve is not perfect - it is able to work exclusively when its gasket is located strictly in the plane of the horizon. The slightest skew, and the valve clinics in a closed or open position. And in that and in another case there will be trouble.

Replacing the fan riser: air valve

In truth, replacing the fan riser on the air valve can be made exclusively in private houses equipped with one bathroom. If we talk about more impressive buildings, then without a fan pipe can not do.

Since we are speeching about the private sector, in which the draining of the waste water is produced into a septic tank or a drain pit, it should be mentioned about the effect of ventilation of the fan riser to work these devices. No, globally, it, of course, will not affect the work of the same septic, but some of the disadvantages are lack of ventilation sewage can bring, for example, an unpleasant smell spreading throughout the local area and beyond its limits. Want to get rid of it? Then make a fan pipe in the house and release over the roof of the house - in this case, all souls will be disappeared into the atmosphere and scatter in the wind.

Sewerage in a house with a fan tube

How to make a sewage riser: a brief instruction

In principle, the installation of fan ventilation does not constitute any difficulties, unless, of course, the system is mounted from zero. If we are talking about coming sewage, then here you have to work a little bit - in particular, it is possible to cut the fastest sunbathing sunbathing, insert a bias tee into it and remove the pipe of the same diameter as a sun bed first on the attic, and from there to the roof. Do not forget to put an umbrella on it to block the path of rainwater.

Here, in principle, all that you need to know about the ventilation of the sewage. No matter how cool, and the fans are needed, and it is not worth getting rid of it. In addition to trouble, this step will not lead to anything else.

In any private house, it is simply necessary to equip the system that is responsible for high-quality ventilation of the premises. To improve these structures, fan elements that prevent air discharge in the ventilation system are considered the most suitable. Siphons, also used in the process of adjusting ventilation, differ in small size and low water reserve. But with a prolonged simple system, water from the siphon evaporates, which allows strangers to penetrate the ventilation system at home without any problems.

The use of fan pipes allows to avoid pressure drops inside the system, ensures the operation of the system with a lack of or completely absent water in the siphon. This problem is especially relevant for country houses, often used for temporary accommodation. A bad ventilation system that transmits sewage smells inside the house becomes the cause of unpleasant odors inside the whole house.

Even not used long enough, the sewage can accumulate volatile gases, which at the first opportunity rise through the ventilation channels. With a lack of fluid in a siphon, a warmer sewer air is capable of penetrating the room.

What are fan pipes made

Elements of sewage structures have no longer enough from asbestos, ceramics or cast iron. Modern material is considered inexpensive, lightweight and convenient plastic in mounting. Most often, PVC elements in combination with rubber seals are used to arrange hermetic sewer systems. In this case, it must be remembered that each type of pipes must be used, taking into account the subsequent operating conditions and operating temperatures. To connect dishwashers and washing machines that use water with high temperatures for their work, it is necessary to use special pipes provided for these tasks.

But considering this issue in more detail, it can be concluded that it is almost impossible. Most often, the diameter of the pipe connected to the plum of the bath and the toilet, does not exceed 110 mm, and the diameter of the tank bundle does not have more than 70mm, the diameter of the siphon is set not more than 50 mm. Another plumbing equipment used in a modern house or apartment is designed to use small drains that do not strongly affect the overall situation.

If there is a task to equip a few bathrooms, the use of fan tubes is justified and necessary.

Fan pipes are used in the following situations:

• if the cottage provides for several toilet bowls or baths, placing them on different floors of the house;
• if the sewer risers will have a cross-section of 50 mm;
• the common sewage system includes pools affecting the total amount of sewage drain;
• the site provides for the use of septic plates capable of causing indous smells.

Installation rules

When installing exhaust pipes, two basic rules should be followed:

1. The diameter of the exhaust pipe should be equal to or exceed the sewage section cross section.
2. When the final exhaust section is located, it is necessary to find a place with a good influx of fresh air.

When erecting fan pipes, the same methods and technologies are used as in the process of mounting the risers. If you figure it out, the exhaust system can be called a finite sewage element installed in a pre-designed ventilation channel.

It is often quite possible if the required number of exits for ventilation is not provided, you can spend exhaust structures through the walls of the room. On the holes that appeared after this, the decorative elements, lattices can be installed on the outer part of the wall.

Fan tube for sewage in a private house will help get rid of unpleasant odors even in rooms with a properly equipped with an exhaust and ventilation system.

The siphons used in sanitary equipment and trapshine are distinguished by small size and are not able to accommodate a large amount of water. This leads to the fact that with not regular use of moisture, it is capable of completely evaporated and open the air from the sewage system.

When installing fan pipes, the problem with the penetration of unpleasant odors from the sewer system is almost completely solved, warm air from all SanPrieborov without problems is output into the atmosphere.

Video - Features of the mounting of the fan riser

If there are one or two sewage risers, the fan pipes can easily be removed to the roof of the cottage or private house. With an increase in the number of risers, the appearance of the building will be spoiled due to a large number of hopping on the roof.

If there are more than three sewer risers, it is possible to install one fan design and equipment of other risers with valves consisting of a spring and rubber seal. This vacuum valve is designed to supply air to the pipeline when the discharged volume occurs when the water is designed in the system. After leveling pressure, the valve is reliably locked, not missing smells into the system.

It is believed that vacuum valves are able to successfully replace the fan pipes. But if the selection of wastewater treatment facilities is assumed on the site, the sewage extractor is simply necessary for the removal of sewage evaporation.

Construction standards and norms based on theoretical calculations, laws of physics and many years of installation of these systems, suggesting exhaust communications and ventilation systems along the contour of heated areas. In this case, the final section should be located in the area of \u200b\u200bthe location of colder air.

Installation of fan pipes is invalid into indoors of the attic. This is due to the fact that in the predatory space it will constantly accumulate an unpleasant smell, then penetrated into other premises of the upper floors of the building.

The installation of sewage extracts near the outer walls of the structure can significantly spoil the appearance of the building. Moving upwards from evil spirits are capable of a relatively small amount of time to leave an unpleasant raid on the roof and upper elements of the house.

An important component of the sewage system in a country house is a fan tube. In essence, this exhaust ventilation pipe, built into the sewage riser and derived through the roof, and thereby connecting the riser with the atmosphere (outer air). The fan tube has several functions. First, it prevents the vacuum of gas formations after passing through it. The vacuum is the reason that water leaves the shells or toilet bowls with a characteristic squall sound.

Why do I need a fan tube?

The use of the fan pipe allows you to avoid this problem.

Secondly, such a pipe removes unpleasant smells from the rapid to the atmosphere from uncleanness, not allowing air pollution indoors. It must be said that in the receiver of wastewater from the plumbing device, as a rule, hydroplate is provided (less often a dry shutter).

This is a curved tube filled with water: when it takes place, part of the water remains in the lower bending of the pipe, overlapping the access of air from the sewage to the room. In other words, the hydraulicum serves as a barrier on the way of unpleasant odors. However, if the plumbing device does not use for a long time, water from the shutter gradually evaporates, and then the smells can freely penetrate the room.

But when the sewage system is equipped with a fan tube, this will not happen even with dried hydraulic assets. In addition, the hydroplays can be broken at the moments of maximum drainage. Fan pipe prevents such broken.

What is a fan tube and what is done?

Fan pipes are elements of the sewage system, and therefore, like other sewer pipes and fittings (tees, angular taps, etc.), they are most often made of polyvinyl chloride (PVC).

At the same time, multilayer polypropylene tubes (PP) are presented on the market (PP), which provide a higher sound insulation. The propagation of air noise is reduced due to the use of material for the manufacture of material with noise absorbing additives, increase the mass of pipe walls, as well as optimizing the design of angular taps.

Diameter and size of fan pipes for a private house

As a rule, the fan pipes have a diameter of 100 mm, which is due to the diameter of sewage pipes, summarized to the toilet and bidet, is 100 mm (which, in turn, is dictated by a stroymometric diameter of these plumbing devices).

However, in some cases, fan pipes with a diameter of 50 mm. Their amount and diameter are determined on the basis of engineering calculation, taking into account primarily the number of instruments, a sewer rim connected.

Most often, one fan tube can serve two or three bathrooms (with a washbasin, shower and toilet) connected to one riser.

At the same time, the maximum load on it will at the time when the water is at the same time in several toilets. In the cottages of a large area (usually over 400 m 2) the bathrooms are often located at different ends of the building.

Then there are several sewer rims, complementing each fan pipe (moreover, do not forget that all pipes are removed through the roof).

Installation of fan pipe

Fan pipes are installed during the installation of the sewage system. The pipeline may consist of both vertical and horizontal sites. Moreover, it is advisable to perform at an angle of 45. Pipes are connected to the socket mechanically.

In each docking node, a rubber seal is provided, providing tightness of the riser. To the walls of the pipes are fixed with clamps with vibration-insulating gaskets, their standard step is 70 cm.

In the case of stone houses, the pipes are carried out through reinforced concrete floors with the help of sleeves (cases) from a hard non-combustible material (usually - from segments of steel pipes). As a rule, the sleeves are laid during the ceiling device.

The sleeve protects the pipe from damage when the building or temperature deformation of the pipe itself is precipitated.

And therefore, the inner diameter of the sleeve must be greater than the outer diameter of the pipe (so, the terminal of the terminal is 110 mm, which means the diameter of the sleeve for it should be 120 mm).

The gap between the sleeve and the pipe is usually close to a soft waterproof material allowing some pipes along the longitudinal axis. For example, a messed or impregnated bitumen rope, silicone sealant, mounting foam, etc.

The withdrawal of the pipe through the roof is carried out in different ways. It can be performed using a specialized roofing passage element (universal or intended for a particular roofing material).

Often there are chimney, inside which fan tubes and exhaust pipes from bathrooms or kitchens pass.

It is unacceptable to combine the fan tube and the supply tube in one channel. In addition, the fan tube must be at a distance of at least 50 cm from the attic window so that unpleasant smells do not fall into the residential premises when the window is open to air.

When it is not possible to establish a fan tube, it can be replaced by a special ventilation (air) valve (usually height 15-20 cm) mounted in the upper part of the sewer rim.

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.

Internal stations from the building must be regularly transported into the external sewer system, for which it is necessary. Its work is ensured by special risers that are equipped with fan pipes. When you remove the sewer riser on the roof in no case you do not need to install additional exhaust devices by type of deflector and flugames. You will need to connect several risers through one fan pipeline. Prepare the ventilation channel in advance. First, connect the scythe tee, then the knee is 45 degrees, then the knee and next direct tee.

1. Remove the piping pipe to a height from 30 to 50 cm from the skate, if the roof is not operated constantly. If the roof is constantly used, for example, as a summer terrace, it is necessary to make an output of three meters high.
2. If two or three risers are installed in your house in the sewage system, equip them with one ventilation pipe.
3. From the windows and balconies, the distance at the installation of the ventilation pipeline must be at least 4m.

Do not assign the ventilation pine pipe under the sink of the roof, it can damage it with snow and the rain that falls on the roof and begins to slide and fall.
