How to make the ventilation in the toilet

A few decades ago, in private homes had no latrines.To meet the needs of nature, people had to relieve themselves in the outside toilet.It was a small building, which always smelled bad.Now, in the world of modern technology, steel equip toilets in their homes.It is very comfortable, because in the cold is not necessary several times a day to run out into the toilet.Naturally, in a private home or apartment bathroom it should be equipped with everything necessary to prevent the spread of odors around the house and to prevent the formation of mold.Therefore, every modern toilet must be equipped with a ventilation system.

ventilation in the toilet.Types

Regardless of where the toilet (in a private house or apartment) in this room ventilation must be present.

Types of ventilation in the toilet:

1. Natural.
2. Force.

The first version says that the air is circulated around the room on their own.Such ventilation settling once during the construction of the house, and consists of a number of air ducts and shafts arranged vertically between the walls.Mines are not only in the toilet, but the bathroom and the kitchen.The openings or entrances to the mine ventilation protected latticed panels and air flow in the kitchen and the bathroom is through the holes located in the house, as well as through open windows and doors.Natural ventilation in the bathroom part of a house is not always cope with the tasks, since the size of the house and layout may not meet the established standards.It happens that the project in the house there is a bathroom (old buildings "Khrushchev" and "Stalinka") and drainage is not provided.Therefore, tenants self-equip one of the rooms for toilet and bathroom: lay a sewer pipe, think over where to make a cesspool (or connected to a centralized sewerage) install plumbing and carry out water pipes.It seems to be done, but as a result of the smell is always present, not only in the toilet, but quickly spread throughout the house.To avoid this, it is possible to install forced ventilation.But before you learn the advantages of mechanical ventilation in the bathroom and how to organize it, let's find out if the ventilation is functioning well in your closet.

How to check ventilation in the bathroom

To see if ventilation works in areas such as the bathroom, kitchen and toilet, you can do the following:

1. Open the door to the toilet.
2. Open to airing or Open your window.
3. Take a paper towel and apply it to the opening of the ventilation channel.
4. If ventilation is functioning normally, the napkin tightly pressed against the grate opening.If this does not happen, then it is possible, the ventilation channel is blocked or not available (ventilation shaft bricked up).
5. can swipe instead light a match or turn on the lighter and immediately bring to the vent.If the flame remains motionless, then ventilation in the bathroom does not work.

If you see that the flame lighters or candles deflected toward the direction of the mine, and even goes out, it indicates that ventilation is normal.Incidentally, in the summer, when the weather is very hot, the air in the duct is fixed, it can make the check.

Now you need to close the window or the window, and doors and check draft in the duct again.So you can understand the need for extra ventilation.According to experts, in any case, must be in the toilet and the bathroom (especially if the bathroom and toilet), install forced ventilation.Then the room will always remain dry, it not only creates a comfortable environment in living rooms, but also keeps in good order and the plumbing in the bathroom furniture and bathroom.

Forced ventilation in the toilet

This type of air flow in the toilet is more suitable for high-rise buildings.If you install a forced ventilation system, it is possible to solve such a problem as severe bad air in the room.It is particularly important to establish ventilation systems and in the case where the natural flow of air in the channel system is connected to the bathroom common.In order to eliminate the spread of odors from the neighboring apartment, you must install a fan having a non-return valve.This scheme allows to cope with the unpleasant odor, if the toilet and bathroom combined.

How to make the ventilation in the toilet

first need to go to a specialty store and buy a fan, as well as related items.It is not easy, because you need to understand what should be the capacity of the device.To do this, multiply the toilet area and ceiling height.The resulting figure - is the amount of your room where you want to install forced ventilation.Now, this figure should be multiplied by the number of air, turn the device performance for 1 hour.For the toilet, there are certain rules, is 25 m3 per hour.Depending on the area of ​​the room, this figure may be higher.

How to choose the fan:

• unit silent.Choose a model with output of up to 40 DCB, since such noise does not affect the human ear and does not interfere with the normal rhythm of life;
• buy ball-bearing fan, it runs silently and will last a long time;
• note the following: the level of humidity in the room, combined bathroom there, whether in the bathroom shower.

is important and the presence of additional functions in the device, for example, a timer delay.It is very convenient - no need each time you enter the bathroom include a fan, just enough to open the door and turn on the fan alone, when a person leaves the room, the fan is still running a few minutes, and then turn off automatically.You can program the device and set the desired time.For example, after you leave the bathroom, the fan will run for 5 minutes, and then turn off on their own.

There are some models of fans that can be connected directly to the switch.When switched on the light in the bathroom, started the work and the unit for ventilation.As soon as the light is switched off, the fan also stops.If your bathroom has no natural ventilation shafts, it is possible to connect the fan to the shaft in the kitchen, only if you need to buy and install a grate with a valve, the fan pushes air where needed.Check valve will not allow air to enter the dressing room to the kitchen.

Yet another feature of the fan: it is possible to acquire a device with a sensor that responds to the humidity in the room.If you went to take a shower in a shared bathroom, a fan is switched on independently, as the humidity in the room rises.

ventilation in the toilet with his hands

design from fans can be different:

1. Axial - flow of air is blown fan blades, passing along its axis.The air pressure to the maximum - 50 Pa.These fans can be installed only in the channel-free ventilation systems.
2. diametral when the main fan wheel looks like a drum.Unfortunately, despite the attractive price performance ratio among fans of this type is low.
3. Centrifugal fans equipped with spiral casing.Considered the most effective and high performance.Among the shortcomings can be identified only one - a high level of noise during operation.
4. Mixed - axial centrifugal.This fan has a good performance, quiet operation, is small.

Axial fan:

Once you decide the type of device for forced ventilation, you need to prevent the vent channel.The vent can get various types of garbage, for example, from the attic.In addition, it quickly becomes clogged with cobwebs, which gradually accumulate dust particles.All this hinders the natural air circulation.

If you live on the top floor, you can manually clean the ventilation shaft.To do this, simply lower on a strong rope of any heavy object (many use the weight) to clean the hole from the web.If you live on the lower floors, then invite the workers housing department or contact a special service that the channel was free in front of the fan unit.

Exhaust ventilation in the toilet.Special features

To make the ventilation in the bathroom, you need to not only buy the fan itself, but also auxiliary materials.Modern building materials market offers buyers a wide range of different boxes and pipes for ventilation systems.This duct may be of various shapes, made of thin metal, plastic, flexible material (an aluminum pipe coated, corrugated plastic, flexible airway channels).

as the organization of the duct is better to use rectangular or circular device.Incidentally, rectangular ducts can be laid directly on top, if you have already done repairs and laid tile.The box fits easily even in the sewer standpipe.

It is best to do some ventilation channels for the kitchen and combined bathroom.Therefore it is necessary to buy another adapter and connection.

Summing up: for the construction of a forced ventilation system, we need:

• propylene tube 1 pc.for a combined bathroom and 2 pcs.for separate (separate for lavatory and bathroom);
• connecting element for combining a round duct with rectangular;
• fan;
• grille for ventilation duct;
• socket with protection from moisture, or if you connect the fan to the lighting system, then the extra few meters electrical cord;
• tools.

If you can not install a fan in the hole of the existing duct, then you need to think in advance how it will pass duct.It can be hidden under the false ceiling.The best place for a fan installation - directly to the ceiling in the middle.If a large room, then it is best to install a few fans, it is desirable that they are located closer to the bathroom or toilet, to ensure a good flow of air in this place.

Look at the photo, so it looks like a vent, extending in the wall of the mine:

When choosing a fan does not need to be guided by such a rule, the more powerful device, the better.Take the time to calculate the area of ​​the premises and to build on this figure.If you set a small restroom powerful fan, then you can come to the back - flow of air will be smaller than the outflow.

can handle yourself if your job with the work on the ventilation unit in the toilet - not to build an additional air duct design of plastic or corrugated pipe.To do this, you only need to install the fan (best buy radial type) directly into the ventilation shaft.Remove the grille located in the exhaust shaft and insert the fan.To secure the device, it is desirable to glue on the glue.Next, you need to build a box to connect the fan to the mains.You can display a separate electrical outlet, or to hold the cable and connect directly to the lamp.

Now you know how to make the ventilation in the toilet independently.In order to avoid problems during operation, we offer to watch this video:

fine workmanship.What else you need to know to

efforts were not wasted, it is necessary not only to choose the right fan and install it, but still adhere to some rules:

• hood should be installed in front of the door to the bathroom.If you decide to install the exhaust device near the door, on the same wall, the airflow becomes weaker;
• not forget to clean the ventilation duct to get rid of debris that fell from the attic or stuck in the shaft hole (plaster, etc.). After repairs tenants of the house;
• if you see that the duct opening is too narrow, then it can be expanded to increase the air flow.To do this, you must use the hammer.If the channel is wide, the hood must be installed plastic pipe, and the remaining space is filled with construction foam;
• hood need to fully deepen the shaft so that the wall was only one grating;
• «plant a" fan can be a lasting glue, sealant or fasteners.By the way, it is best to use an adhesive or sealant, these materials further improve sound insulation and reduce the vibration of the device during operation;
• connecting exhaust design to power, you must hide the cable in a prepared box.This is possible if the ventilation in the bathroom is equipped initially during repairs in the bathroom.If the repair is done for a long time, and not to break the tile, box for a wire is run along the wall, putting in favor of plastic.

How to care for a fan?

Caring for forced ventilation system a must.From time to time it is necessary to check the "traction" in the toilet and the bathroom and wash the mesh from contamination.If the mesh is clogged, the fan will not work and may even go wrong, so it is necessary to wash the grid with warm water and any detergent.Suitable ordinary liquid soap.
