Proper ventilation in the bathroom and toilet in a private house. Installing ventilation in the bathroom and toilet with your own hands Natural exhaust in the bathroom

Designing a private house without taking into account the ventilation system is considered incorrect. For a toilet, bathroom, air change improves its composition, prevents mold from appearing on wall surfaces and ceilings, and is flexible. Air exchange improves the microclimate in the premises, protects structures from destruction.

Air exchange options for bath and toilet

Ventilation in the bathroom and toilet in a private house is carried out mainly natural and forced. The first option is more economical and easier to implement. Does not require electricity costs. A gap between the door and the floor is enough for fresh air to enter through it. Sometimes for these purposes, a ventilation grill is equipped at the bottom of the door. But the effectiveness of this method is low. The required air exchange is not performed, so mechanical devices are installed.

Forced air change does not depend on external conditions. The flow is supplied and removed in the specified mode. Energy dependence is the main disadvantage, because the fan is powered by electricity.

Features of ventilation of the bathroom and bathroom

Ventilation in the bathroom and toilet in a private house can be installed by hand. At the same time, there are no significant differences between devices and installation technologies. Difficulty can be caused by the fact that the main ventilation duct is located at some distance from the bathroom. To ensure the required and high-quality air exchange, it is necessary to organize an inflow fresh air. For this, a separate ventilation sleeve is assembled specifically for the bathroom. It should be oriented to a common (stationary) duct.

When the main channel is located in the bathroom through the wall with the toilet, it is allowed to install ventilation grilles in both rooms. In this case, the exhaust shaft should be located directly behind the wall of the toilet room, but not behind the door.

Attention! Mechanical air exchange is universal. It is suitable for combined and non-combined bathroom and bathroom ventilation systems.

With a small room size and a closely passing main channel, an overhead fan model is mounted. It is quite powerful, does not create noise in operation (up to 40 dB), consumes a small amount of electricity, fits into any room design.

Fan performance selection

The efficiency of air exchange depends on the correctly selected power of the equipment. Approximately its calculation is carried out according to the scheme.

  • The area of ​​​​the bathroom (bathroom) is calculated.
  • The result obtained is multiplied by a factor of 6 (when using the premises up to three people) or by 8 (with a visit of 3 or more people).
  • The resulting product of numbers is the required fan performance.

In an example, it looks like this. Bathroom with an area of ​​15 sq.m. used by 4 people. For calculations, a correction factor of 8 is taken. Then the required fan performance will be: 15 * 8 = 120 cubic meters / h.

Attention! If it is necessary to ensure air exchange in a room with an area of ​​​​more than 15 sq.m., the overhead fan model will be ineffective. Centrifugal duct blowers are better suited here.

Installation procedure

  • At self-assembly ventilation, the ventilation duct is preliminarily cleaned. For this, a brush or a load suspended on a rope is used. It descends several times into the channel in a rotational motion. The channel is cleaned if the indicator - a sheet of paper brought to the ventilation shaft - deviates towards the room or is not held by gravity on the grate.
  • All work is carried out with the electricity meter turned off at a height. To do this, you need to provide a stepladder.
  • Installation of the unit is carried out under the ceiling itself in the zone of maximum humidity, opposite the source of air intake.
  • Given the size of the fan and the location of the power supply, the position of the wiring and the installation itself is marked.
  • Installation work is carried out in the presence of a grate, glue for fixing it, a screwdriver, dowels. You may also need a piece of hose for the duct, as well as a drywall box to mask the pipe and unit.
  • The fan is installed in the air duct. If the model is of an overhead type, the box is first strengthened.
  • The terminals on it are connected to a two-core cable line section 0.2 cm.
  • The fan housing is mounted directly. For this purpose, latches are provided in most models. Otherwise, dowels are used for these purposes.
  • If it is impossible to directly connect the installation, the air duct is built up. It is disguised in a box or decorated. In this capacity, a flexible, semi-rigid or rigid hose is used.
  • For economical use of electricity and rational use of equipment, it is convenient to start the fan in operation along with turning on the light: you need to run a cable from the fan to the switch.
  • After installation and connection, voltage is applied to the network, the operation of the forced ventilation system is checked.

Before assembling the fan into the duct, the power supply is also turned off, but the procedure is somewhat different.

  • The unit in the channel is placed strictly vertically, as deep as possible. This position is securely fixed so that during operation it does not fall from the generated vibrations.
  • The supply cable must be new, without kinks and damage to the insulating winding, designed for "zero" and phase. It connects to the fan.
  • In a convenient place, a switch is installed to start the equipment in operation.
  • Voltage is applied to the network and the correct connection is checked, as well as the operation of the equipment.

Attention! The main link of forced air exchange is the ventilation unit. You need to buy it according to the calculated parameters with a passport and a manufacturer's warranty.

Check valve in the ventilation system

With incorrectly selected equipment or inaccurate calculations, the ventilation system does not work efficiently enough. As a result, the effect of reverse ventilation is observed. The exhaust air is blown back into the bathroom or toilet. Installation check valve solves this problem by blocking the reverse flow.

The choice of device depends on the type of ventilation system. With a vertical arrangement of the channel, air flows move along it. To block them, a horizontal valve is installed. In the case of longitudinal installation of the air duct, the cut-off piece is mounted vertically.

Some notes on the arrangement of ventilation in the bathroom and bathroom

  • The fan is bought according to the estimated performance. Its increased power "eats" expensive electricity without increasing the efficiency of the process.
  • You can automate air exchange in a bathroom or bathroom using a timer. Regardless of the presence or absence of the owners in the house, it will maintain the specified mode, periodically turning the system on and off.

Thus, in a private house, ventilation in rooms with high air humidity, the release of unpleasant odors is definitely needed. Another thing is how it will be organized. Often, along with forced air exchange, natural aeration is used (open window, door, etc.). From the existing methods, you can always choose best option and do it with your own hands to create comfortable living conditions.

How to make ventilation in the bathroom is a really serious question. He does not stand in front of a resident of city apartments, because natural ventilation has already been installed in the bathroom in an apartment building. But in many private houses built 30-50 years ago, this problem is acute. Because in those days, few people cared about ventilation in general, and even more so in the bathroom.

The importance of ventilation in the bathroom

Ventilation in the bathroom - a system at the level of plumbing and sewerage. I mean, it's also important. After all, this room belongs to the category of wet, here the humidity is often almost one hundred percent. And this is condensate, which negatively affects the condition of surfaces, plumbing and furniture. So, humidity must be understood. Which way? Only ventilation.

Slots and leaks in the door and windows solve this problem inefficiently. Smudges on the walls and drops on the ceiling, a misted mirror, wet towels are not the only negative factors no ventilation system. Humidity is the cause of the appearance of mold and fungi, which in turn will adversely affect the health of the residents of the house. The appearance of a musty smell is also the reason for the lack of an extract.

Therefore, ventilation in the bathroom must be equipped without fail, even if the house has already been built and is in operation. At the same time, it is necessary to install a better forced system in the rooms with a maximum outflow of moist air. Today, a combination of two systems is increasingly being used, when the fan turns on during the use of the bathroom, and when the room is idle, natural ventilation functions.

Norms and requirements

In principle, the main requirement for a bathroom is an air exchange in it, equal to 25 m³ / h. It doesn't matter what size it is. And if in other service premises (except for the toilet and kitchen) the air mass exchange rate is taken, then a standard value is required here. It is under it that the ventilation in the bathroom is equipped.

It is important to adhere to one strict requirement - the volume of supply air must be the same or more than the exhaust air.

Types of ventilation in the bathroom

As in other areas of the house, the bathroom can use either natural ventilation or forced ventilation.

Natural

Equipping natural ventilation in the bathroom, it is necessary to strictly take into account the norms of air exchange. Indeed, in such a system there are no devices and devices that forcibly (forcedly) removed the exhaust air. Therefore, it is important to choose the right section of the ventilation duct, which is equipped in this room.

For example, a square shaft with sides equal to 10 cm, or a pipe round section with a diameter of 150 mm pass through themselves 30 m³ / h. That is, the installed ventilation shaft with such dimensional parameters will be sufficient to provide the required air exchange. But, as mentioned in the previous section, another important component of the air flow is the flow of air into the room. Therefore, it must be organized.

For example, they do this.

  1. Leave a gap between door leaf and floor, through which the air flow penetrates into the bathroom. In this case, the air flow is organized through the living quarters.
  2. Make holes in the bottom of the door.
  3. Do through hole in the wall closer to the floor, where the air supply valve is inserted.

The first option is used most often.

Forced

This option is considered optimal, because it becomes possible to create all conditions for the most efficient air outflow. To do this, you will have to correctly calculate the performance of the fan. In principle, it should be no less than air exchange, that is, no less than 25 m³ / h.


From the wide variety of offered fans, the one that seems more acceptable to you for the bathroom is selected. Namely, whether it matches the design with the finish. And will it fit in the size of the hole in the ventilation duct.

The last requirement requires clarification.

  1. If this is a wall fan, then it should close the hole in the wall or stream, but the blades of the device itself should not be much larger than the diameter of the hole.
  2. If it's a channel instance, then it just needs to fit snugly into the channel.

In some cases, it is necessary to widen the hole in order to install the device. It requires certain victims if, for example, ceramic tile already laid. Around the hole, it will have to be dismantled or cut off. But in any case, with the help of a fan, the exhaust system will work better.

How to understand that it is necessary to improve the ventilation system

The first sign is the appearance of mold in the corners of the room. This indicates that the humidity is high and constant. That is, ventilation does not have time to remove air outside the room. Here she is deposited in the corners. And heat creates additional conditions for the appearance of microorganisms.

How to improve ventilation in the bathroom

Everything will depend on what is causing the poorly functioning ventilation. If the bathroom uses a natural system, then there are two reasons:

  1. Insufficient air supply. It can be increased by increasing the gap between the floor and the door leaf.
  2. The ventilation shaft is blocked. This is a more serious problem that requires a serious approach to its solution. The channel must be cleaned, which is not always possible with independent approach. If this is ventilation in a private house in which a conventional riser is installed through the floors and the roof, then you can try to lower the load from above so that it pushes the garbage inside. And already from the inside of the room to get the last one.

If the bathroom is used forced system, then you need to check whether the installed fan is suitable for performance. It may also turn out that he simply cannot cope with air exchange.

These are the three reasons you need to address in order to improve the ventilation in the bathroom.

How to make ventilation in the bathroom with your own hands

In principle, ventilation in the bathroom is not a problem. The main thing is to accurately set a goal - it will be natural or forced.

Natural

To do this, make a hole in the wall for a pipe with a diameter of 110-150 mm. It is done under the ceiling in the wall, which will separate the room from the street. Inserted into this hole air valve, which is closed on both sides with decorative grilles. It is better to choose a valve with a regulator in the form of a handle and a valve, with which you can close the hole and open or leave a small gap.

Forced

Instead of a valve, a fan must be installed in the same hole made in the wall.

  • If this is a wall model, then you need to insert it into the wall plastic pipe, which is closed from the outside with a lattice.
  • If this is a channel option, then the device itself is installed in the wall and closed with bars on both sides.

The most difficult thing in this business is to make a through hole, which will require a puncher and a diamond crown of the required diameter. Installing and fixing the fan is simple. The wall-mounted one is attached to the wall with four self-tapping screws on plastic dowels, the channel one is simply inserted into the hole without any fasteners. If necessary, the gap between the device and the wall is filled with mounting foam.

Installing ventilation in the bathroom and toilet will help prevent the appearance of dampness, mold and fungus. This must be foreseen before the start of a major overhaul. In these rooms, there are constant temperature changes and increased air humidity, which over time will certainly affect the condition of the walls and ceiling, where pathogenic flora will begin to develop. To carry out the work, you can invite the master or do it yourself.

Types of ventilation systems

Ventilation in the bathroom of a private house or cottage is quite simple: the air duct is located under the ceiling and is brought out to the roof or to a common hood. When the door is opened, the air flow enters the room and exits through the pipe, creating natural circulation.

IN apartment buildings the situation is a little more complicated: the entire entrance is connected to one ventilation duct. In apartments located on the lower floors, the risk of clogging the air exchange system is much higher.

Forced ventilation in the bathroom.

The main types of ventilation include:

  • natural;
  • forced;
  • combined.

The choice depends on the place of residence and condition. In multi-storey buildings, forced ventilation is preferable.

How does natural air exchange work?

A properly installed extractor hood works very simply: air enters the bathroom or toilet, and then exits through the ventilation shaft. The temperature difference between indoors and outdoors creates a draft, with the help of which air flows are constantly moving.

When air leaves the hygienic room, a low pressure zone is created, the difference is compensated by the inflow from the street, which enters through the open window during ventilation. Thus, natural ventilation occurs, which is called forced ventilation.

Natural ventilation cannot take place if the door to the bathroom or toilet is hermetically sealed. For normal circulation of air flows, it is necessary to provide a gap between the door and the floor, through which fresh air will constantly flow.

In case of violation of the natural or mine), problems instantly arise: humidity rises, unpleasant odors appear, condensate can accumulate on smooth surfaces and heating pipes.

Determination of blockage in a pipe or shaft

The working condition of natural ventilation is best checked in the cold season. For this you need:

  • open a window in a house or apartment for cool air to enter;
  • close by attaching a sheet of paper;
  • if the sheet is not pressed tightly by the air flow, then the ventilation is clogged.

The degree of blockage can be determined by the behavior of the paper. If it is held weakly, then the air passes, but not in full. If the sheet does not hold at all, then the channel is completely clogged. In both cases, cleaning or installation of a device for forced ventilation is required.


Forced ventilation

Unlike natural ventilation, forced ventilation in the toilet and bathroom is provided by a fan built into the air exchange system. When choosing it, you need to take into account that it will consume electricity and work at high humidity.

Installation of ventilation in the bathroom and toilet, its cost, durability, performance and noise level depend on. It is of three types:

  • diametrical;
  • axial;
  • radial.

The first device is not suitable, it is designed to work in air conditioning systems and heat guns. You need to choose between two other types of devices.

The axial model differs from the radial one in lower cost and more power, but at the same time it produces more noise. The impeller of the axial fan is driven by an electric motor, the air flow goes along the axis of the motor, it is installed directly on the exhaust hole.

Radial fans rely on centrifugal force to work, so power consumption and noise levels can be reduced by changing the pitch of the blades. Install such a device in the ventilation pipe, at some distance from the grate.

How to choose a fan

Buying the right fan is hampered by a large assortment of various models, so it’s better to use a hint. When choosing an exhaust device, several factors are taken into account at once:

These indicators will help you make your choice. You can calculate the required performance as follows:

  • determine the area of ​​the room;
  • multiply it by 5;
  • add 20% to the resulting number.

This will be the choice of device performance with a small margin. The expected change of air in the room is at least 5-8 times a day.

Installing a fume hood

You can install a fan in the toilet with your own hands, as in the bathroom, if there are already ready-made air ducts. Before starting installation, it is necessary to check them for blockages, and if necessary, clean the channels with a special brush. If you cannot restore air exchange on your own, then it is better to call a specialist who will do it professionally.

With a separate location of the bathroom and toilet, it is enough to put a fan in one of the rooms, provided that they are connected by a vent in a common wall and air circulates freely between them.

With a wall-mounted axial fan, everything is simple - it is installed on top of the ventilation hole:

  1. 1. The wall around the entrance to the mine is coated with polymer glue, silicone or liquid nails.
  2. 2. The working part of the fan is completely recessed in the hole, and the outer part is pressed tightly against the wall.
  3. 3. Install the grid and fix the front cover with self-tapping screws or dowels. They usually come with the device.
  4. 4. Lay the cable and connect it to the mains.
The stages of installation work are performed in the following sequence:
  1. 1. The cover of the terminal box is unscrewed.
  2. 2. The electrical wires are inserted into the latch, which is located on the cover.
  3. 3. The wires are connected to the terminals labeled "linear phase" and "zero".
  4. 4. The cover is put in place.
  5. 5. The device is plugged into the socket to check the correct connection.
  6. 6. The diameter of the air duct is adjusted in accordance with the dimensions of the fan. If necessary, use an additional plastic pipe.
  7. 7. The device is mounted in an air duct at a certain distance from the grate. To do this, use detachable clamps with rubber seals or special flange connections with adapters (for square section). When fastening, use at least 4 bolts.

The ventilation grill is put in place, and the wires are covered with a special box to protect them from moisture.


Some people, in order to save energy, prefer to turn on the fan automatically when the light in the bathroom or toilet is turned on. The operation of the device in this mode may not be enough to maintain an optimal microclimate. This must be taken into account when connecting wires to the switch.

In the absence of confidence in own forces it is better to turn to specialists. They will quickly solve the problem of ventilation and carefully perform all work in compliance with the rules and regulations.

When installing a mixed system (natural and forced), it is necessary to have two exhaust openings. One of them will have a fan installed. A mixed supply and exhaust system is used in large rooms, with high humidity, where the usual supply ventilation not enough.

Hello dear friends. Today we will talk about very important, although, at times, not conspicuous things. When planning the design or renovation of bathrooms, the ventilation system should always be considered. The problem of air exchange is a serious and very important stage of repair. In SNIPs and regulations regarding ventilation, the standard of air exchange norms in rooms in which there is an abundant release of water vapor is always prescribed in separate paragraphs.

It should be remembered that ventilation is not only a matter of comfort and convenience. First of all, it is very important for health. Moreover, in rooms from which water vapor is not removed in proper quantities, a fungus or mold always starts.

If the harmful flora has already begun to develop under the tiles or on the sides of the shower cabin (and it is not so easy to notice the fungus, it develops very secretly for about a year), then the lack of a ventilation system helps it grow and spread in the form of spores through the air.

Construction guides of all countries and peoples contain a number of standards that must be strictly followed in order to ventilate wet rooms.

Ventilation systems should enrich the bathroom with 25 cubic meters of air every hour. For a combined bathroom (bathroom + toilet), ventilation should bring 50 cubic meters air. Moreover, these standards are minimal.

Specialists in ventilated systems advise to ventilate the bathroom with an air exchange of 75 cubic meters per hour and 150 cubic meters for combined bathrooms.

For bathrooms, there are two types of ventilation: natural and forced. The method of application of each of them depends on the specifics of air exchange. Natural ventilation provides air exchange by sucking it from external environment, which can take place only because of the pressure difference.

Air masses can get inside through a window, a door, a ventilator and so on. It must be recognized that, in the case of a separate toilet room, natural ventilation is acceptable. However, for combined bathrooms, it is often ineffective.

Types of ventilation systems

Professionals advise using two types of ventilation systems:

  • duct ventilation system;
  • channelless ventilation;

The difference between these systems is obvious from their names - in the first design there is a ventilation duct, in the second - air flow is provided without it.

When working with bathrooms or bathrooms, it is desirable to exclude the creation of separate channels. It is customary to create an opening in the wall and remove the exhaust air into the general ventilation branch of the building. This procedure is not only more convenient and less expensive, but also more rational. Of course, this is applicable in multi-storey urban buildings. But, if we are talking about a private house, then you need to design ventilation at the stages of construction, in the process of building walls.

The air supply to the bathroom and toilet is realized, as a rule, through one channel - in the bathroom, after which an additional intermediate opening is created in the wall between the bathroom and the toilet for the passage of the exhaust air.

An exhaust fan designed for ventilation in the bathroom through the toilet can have a wide variety of appearance and size. But the most important thing is the power of the fan. It must match the current in the wiring.

Fans have the following design differences:

  • the axial model moves air parallel to the axis of the instrument. This is done thanks to special blades. These systems are designed exclusively for channelless designs;
  • diametrical models, which have a rather low productivity, have special drum-type wheels in their design;
  • a centrifugal type device with a spiral housing guarantees extremely high performance, however, during operation, the system creates quite a lot of noise;
  • the combined, centrifugal-axial device is more silent while working with the same efficiency as a simple centrifugal system.

Norms and requirements

We will study SNIPs and others regulations in order to understand how much new air should come into the bathroom or toilet during ventilation.

According to the regulatory documentation, bathrooms with dimensions of about 10 square meters and more should once receive new influxes of air masses hourly.

More than 30 cubes should leave the bathroom and toilet every hour. If the bathroom is large, then the calculation goes to the area of ​​​​a small living room and multiplies by 1.5 (due to high humidity). These are the ventilation rates, these numbers are the minimum requirements.

Criterias of choice

It should be understood that in cases where natural ventilation in the toilets through the bathrooms cannot be realized (it is not possible to guarantee the influx of even 20 cubic meters of fresh air per hour), then it is necessary to install forced ventilation systems.

There are three types of ventilation:

  • exhaust system;
  • supply system;
  • mixed.

As for the exhaust systems, we have already discussed them - the air comes from outside, and the waste masses are discharged into the ventilation ducts.

The principle of supply ventilation is different - outside the bathroom or toilet, air masses are forced in, after which they are forced out into the channels. This is the best and rational system for apartments.

When ventilating a bathroom in a private house, it is best to use mixed systems. They combine exhaust and supply systems. Air, thanks to mixed technologies, is removed and renewed with the greatest efficiency.

In order to hide the structures, decorative lattices are used. They can not only remove the technical details of ventilation from view, but also make the bathroom interior more stylish.

Household ventilation systems are:

  • channel;
  • radial.

Both types are intended for installation at the outlets of ventilation ducts. The duct fan, as a rule, has a rather mediocre design, because it is hidden in the duct itself. However, it is customary to equip a radial fan with an attractive housing; these systems not only provide efficient air exchange, but also fit perfectly into the design of your interior.

Diagnostics of the current system, if any

Before you begin to upgrade the ventilation system or clean its filters, it is necessary to carry out scheduled diagnostics. The condition of the ventilation device installed according to the principle “to the bath through the toilet” must be thoroughly studied. No need to be lazy to remove the grilles and clean the entrances and exits of the channels from dust.

To start, you need and . To do this, a paper sheet must be placed in front of the vent. If the paper sheet is strongly attracted to the ventilation niches, then there is a draft. If the sheet is motionless, then there is a clear lack of ventilation draft in the system.

It must be remembered that the design of the system is such that the pressure difference is due to the temperature difference, therefore, on a hot summer day, the draft is several times weaker than in winter or autumn.

However, even if the draft is present, and the exchange of air masses is excellent, it must be understood that this does not guarantee 100% complete correct operation of the ventilation systems.

It is imperative to check the status of the channel as much as the situation allows. Channels are cluttered with various objects, cobwebs, dust or fragments of concrete and brick after a global repair. After the system is clean, there are no more obstacles in the way of the air, and the ventilation devices themselves are clean, you can begin to modernize and improve the system itself.

Checking with a sheet of paper must be carried out twice: the first time with behind closed doors, the second time - with open.

Check if available open door it is also desirable to carry out twice - with open air sources (open a window or front door) and fully closed.

If, after sealing, the draft has dropped to almost zero, then you need to think about additional fans or compact devices for ventilation.

Specialized gratings are installed in the doors of bathrooms and toilets - air enters through them even when the doors are completely closed.

Do-it-yourself installation

When there is no ventilation system in the bathroom or toilet, then it's time to start designing and installing it yourself. Such work is carried out quite simply.

In apartment buildings, the systems are designed so that the ventilation ducts are located on the back of the baths and bathrooms. The whole procedure will consist in the fact that it is necessary to carefully create a hole and bring it into the ventilation channel. High-rise buildings should already have niches leading to ventilation ducts.

Niches themselves are usually equipped with radial, axial fans; devices are connected to power sources, one of the wires is connected either to a separate switch, or to the same one that opens the light circuit in the bathroom. This is quite handy, as the fan will be guaranteed to run when the lights come on in the bathroom.

Range modern systems on the market of ventilation products and services allows you to install many additional attachments - gyroscopes, temperature sensors, humidity controllers, speed controllers, timers. After that, the hole is closed with beautiful decorative gratings.

In cases where the bathroom is not combined, when the bathroom contains a ventilation duct, and the toilet does not use the same technology, only twice. The first fan is installed in a niche between the bathroom. and a channel, the second - in the second niche, between the bathroom and the bathroom.

In the case when it is necessary to install ventilation in a toilet in a private house, with your own hands you can make not only an exit to the ventilation duct, but also the ventilation duct itself. Experts advise either to take into account the channels when building walls, or competently connect to the exhaust system of the furnace (if any).

Let's move on to practical schemes and projects of ventilation systems.

System design

For the introduction of fans into wall openings, the most correct is to use not only decorative grilles, but also filtration systems. If you have to knock out an additional hole between the bathroom and the bathroom (for air wiring), then the filter between the two rooms is a very rational piece of the ventilation system. After all, polluted air from the toilet will not be able to penetrate into the bathroom.

Imagine in the figure a diagram of connecting a fan to a common wiring:

The installation scheme of the ventilation system consists of the following strategic steps:

  • mounting the air duct (it is important to choose the correct diameter and length);
  • design an optimal exhaust system for bathrooms (taking into account the power of the electrical wiring);
  • with your own hands in the toilet (you can also with the help of a master) make a neat, even hole;
  • Install ventilation in the toilet or bathroom;

When ventilation systems need to be introduced into the toilets and bathrooms of private houses, it is necessary to start by organizing the connection of the ventilation duct to a common chimney; or create a ventilation duct.

When designing a new channel, it is necessary to carefully consider all the stages of laying ventilation through the bathroom.

We advise you not to use metal boxes to create a ventilation duct of a private house. Not only that metal constructions oxidize and require dismantling and replacement every 5 years. If the exhaust air duct is used with a direct outlet to the chimney, then due to carbon dioxide, the metal surface of the box will become even more corroded.

The most rational is the installation of plastic boxes. No wonder they almost completely ousted metal from the market.

Try to avoid corrugated pipes, they are optimal only for short ventilation ducts.

The boxes must be installed during all repair work. Moreover, it is desirable to make the installation even before the process is started.

However, even after you have personally designed the entire system, made sure that it functions and complies with all standards, ventilation may fail. The problem may be with inaccuracies in the calculation of the cross sections of the ventilation ducts. Also, the most common mistakes is an incorrect installation.

If a lot of time has passed after you built the ventilation system, and after this time the system began to noticeably junk, it means that a lot of debris has most likely accumulated in the channel, which falls either from the side of the roof or from the air. If one of the neighbors did this overhaul that affected the box, the reason may be in traffic jams of construction debris located across the air passage.

  • Experts advise not to postpone the inspection of the ventilation system all the time for later, it is highly desirable to service the fans a little earlier than it starts to fail.
  • As a rule, if the inspection is constantly postponed, then flakes of dust, cobwebs or poplar fluff fall into the fan axis, block the rotor and stator motor for a long time, after which the fan simply fails.
  • Of course, buying a new motor or a whole fan is a simple solution to this issue, but you still have to clean the ventilation duct. Much easier to do this work on time.
  • Do-it-yourself fan maintenance includes cleaning the fan blades, thoroughly cleaning the ventilation grilles, and replacing all filters (if any).
  • After that, it is necessary to check the air draft using a sheet of paper or a lighter flame (we described above how this procedure is performed). If the fire from the lighter (or match) deviates at an angle of 40-50 degrees, then the operation of the fan is considered normal, if the flame does not deviate, then the ventilation duct is considered clogged and further operation of the fan is load.
  • In such cases, it is best to call a specialist, but you can also handle it yourself. If various attachments are included in the ventilation system - external interfaces, sensors, thermometers, remote controls, then it is imperative to contact a special organization.
  • Also, experts refer Special attention on the power of household wiring and mains. Fans have two parameters by which they are distinguished - the generated pressure and power. These characteristics are related, because the greater the power of the motor, the stronger the pressure. You need to be well aware of the condition of your wiring, try to avoid high-powered fans.

High-quality ventilation in the bathroom and toilet is an integral element of the comfort and cleanliness of these premises. Unlike other rooms, they put forward increased requirements for convenience and accuracy.

The intended purpose of such sanitary facilities implies the need to constantly maintain cleanliness close to ideal. The ventilation system plays one of the leading roles in this process.

Cleanliness and freshness of the air is an indisputable condition for a comfortable stay in the room. But if in living rooms this condition is quite simple to observe with the help of ventilation through the windows, then in the toilet and bathroom there are some difficulties with it. Not every bathroom in a private house can boast of having a sufficient window opening. Features of the location of the premises in the apartment rarely imply the presence of a window as such.

Typical multi-apartment buildings, as a rule, "hide" the sanitary zone in a "blind" box of a small area with a common air ventilation duct. It is implemented as a small opening under the ceiling, working according to the natural supply and exhaust principle.

Consequences of poor ventilation

Sanitary facilities in apartment buildings, equipped with windows, are mostly shared bathrooms in high-rise buildings of a non-standard type. However, even if there is window opening ventilation in the bathroom and toilet may not be intensive enough, which will certainly cause discomfort to residents and visitors.

In fact, the rooms that most of all need high-quality cleaning from odors and moisture have the most difficult mechanism for the operation of the hood. In addition, the appearance of unpleasant odors is far from the most dangerous problem of poor ventilation of the sanitary zone. The accumulated excess moisture is a favorable environment for the development of fungal mold and pathogens.

To avoid violating hygiene standards, it is recommended to choose the right type of ventilation for the bathroom and toilet in a timely manner.

It is also allowed to improve existing ventilation - this can be done independently. This measure is quite relevant for typical high-rise buildings.

Two types of ventilation systems

Approving the best way to make ventilation in the bathroom and toilet usually comes down to choosing between two main system options - natural and forced. Each of them has its own merits. Comparison of options should be based on the current need and the effectiveness of the established this moment systems.

There are practically no difficulties with how to check the ventilation in the sanitary rooms. If the room is stored for a long time bad smell, there is a feeling of stale, stale air, the level of humidity rises noticeably - this is a signal to check the condition and effectiveness of the vents. The appearance of fungus on the walls and wet plaque is a direct evidence of the need for urgent modernization of the air exchange system.
