How to make ventilation in the toilet

A few more dozen years ago there were no toilets in private houses. To satisfy your natural needs, people had to cope in the street toilet. It was a small structure in which it always badly smelled. Now, in the world of modern technologies, toilets began to be equipped in homes. It is very comfortable, because in the cold time you do not need to run out several times a day into the toilet. Naturally, in a private house or apartment, the bathroom should be equipped with everything necessary to eliminate the spread of the smell throughout the house and prevent the formation of mold. Therefore, each modern toilet must be equipped with a ventilation system.

Regardless of where the toilet is located (in a private house or multi-unit), ventilation must be present in this room.

Types of ventilation in the toilet:

1. Natural.
2. Forced.

The first option suggests that air circulates by indoors. Such ventilation is placed immediately during the construction of the house, and consists of several air ducts and mines located vertically between the walls. The mines lead not only to the toilet, but also in the bathroom, as well as to the kitchen. Holes or inputs in the ventilation shaft are protected by lattice panels, and the air flow into the kitchen and the bathroom is carried out through the holes located in the house, as well as through open windows and doors. Natural ventilation in the toilet of a frequent house does not always cope with the tasks, as the size of the house and the layout may not comply with the established standards. It happens that on the project there is no bathroom in the house (old houses "Khrushchev" and "Stalinki") and sewage is not provided. Therefore, the tenants independently equip one of the rooms under the toilet and the bathroom: they are paving the sewer pipe, they think over, where it is better to make a cesspool (or connected to centralized sewage), installed plumbing and conduct water pipes. It seems to be done, but as a result, the smell is constantly present not only in the toilet, but also quickly spreads throughout the house. To prevent this, you can install forced ventilation. But before you find out the benefits of forced ventilation in the bathroom and how to organize it properly, let's find out whether the ventilation is well functioning in your toilet.

How to check the ventilation in the bathroom

To find out if ventilation works in such facilities, like a bathroom, kitchen and toilet, you can do the following:

1. Open the door to the toilet.
2. Open the window to the ventilation or swipe the window.
3. Take a paper napkin and attach it to the ventilation channel hole.
4. If ventilation is functioning normally, the napkin snaps tightly to the lattice hole. If this did not happen, then the ventilation channel is clogged or not at all (the ventilation shaft is closed).
5. You can instead of a napkin to light the match or turn on the lighter and immediately bring to the ventilation hole. If the flame remains without movement, it means that ventilation in the bathroom does not work.

If you see that the flame lighter or candles deviates towards the mine and even flies, it indicates that ventilation is normal. By the way, in the summer, when it is very hot on the street, the air in the ventilation canal remains fixed, it will make it difficult to check.

Now you need to close the window or the window, as well as the door and check the craving in the ventilation channel again. So you can understand the need to install additional ventilation. According to experts, in any case, it is necessary in the toilet and the bathroom (especially if the bathroom is combined) to establish forced ventilation. Then the room will always remain dry, it not only creates comfortable conditions in residential rooms, but also retains pluck and furniture in the toilet and bathroom.

Forced ventilation in the toilet

This type of air inflows in the toilet is more suitable for multi-storey houses. If you establish a forced ventilation system, you can solve such a problem as a heavy unpleasant air indoor. It is especially important to establish the ventiometer and in the case when the natural channel of the air flow system in the bathroom is connected to the common. To exclude the spread of odors from neighboring apartments, you need to install a fan having a check valve. Such a scheme will help to cope with unpleasant flavors, if the toilet and the bathroom are combined.

How to make ventilation in the toilet

First you need to go to a specialized store and purchase a fan, as well as related elements. It is not easy, as it is necessary to understand what the power of the device should be. To do this, you need to multiply the area of \u200b\u200bthe toilet to the height of the ceiling. The resulting digit is the amount of your room in which you need to establish forced ventilation. Now this figure must be multiplied by the multiplicity of the air exchange, the productivity of the device is obtained in 1 hour. For the toilet there are certain norms, it is 25 m ³ in hour. Depending on the room area, this figure may be greater.

How to choose the right fan:

• silent device. Choose models with up to 40 dcs, since such noise level does not affect human hearing and does not interfere with the normal rhythm of life;
• buy a ball bearing fan, it works silently and last long time;
• note the following: the level of humidity in the room, is it combined with the bathroom, is there a shower in the bathroom.

It is important and the presence of additional functions in the device, for example, time delay timer. It is very convenient - no need to turn on the fan every time you enter the toilet, just open the door and the fan will turn on yourself when a person leaves the room, the fan still works for several minutes, and then automatically turns off. You can program the device and set the desired time. Suppose, after you leave the restroom, the fan will work for another 5 minutes, and then it will turn off.

There are such models of fans that can be connected directly to the switch. When the light is turned on in the restroom, the air ventilation device is started. Once the light is turned off, the fan also stops working. If there is no natural ventilation mine in your bathroom, you can connect the fan to the mine in the kitchen, only then you need to buy and install the lattice with the valve, so that the fan will stick the air where necessary. Check valve will not allow air from entering the kitchen.

And one more feature of the fans: you can purchase a device with a sensor that reacts to the appearance of moisture indoors. If you went to take a shower in a joint bathroom, then such a fan will turn on on your own, since the humidity in the room will increase.

Ventilation in the toilet with your own hands

The design of the fans can be different:

1. The axial - the air flow is injected by the fan blades, passing along its axis. Air pressure to the maximum - 50 Pa. Such fans can only be installed in the chamberless ventilation systems.
2. Diametrical when the main fan wheel looks like a drum. To a great regret, despite the attractive price, the performance coefficient of this type of fans is low.
3. Centrifugal fans are equipped with a spiral case. Considered the most effective and high-performance. From the shortcomings, only one can be distinguished - this is a high level of noise when working.
4. Mixed - axial with centrifugal. Such a fan is characterized by good performance, it works silently, has a small size.

Axial fan:

After you decide with the type of device for forced ventilation, you must perform the prevention of the air channel. A different debris can fall into the vent hole, for example, with a attic. In addition, it is quickly clogged by a web on which dust particles are slowly settled. All this interferes with natural air circulation.

If you live on the top floor, you can independently clean the ventilation shaft. To do this, simply omit on a strong rope any heavy item (many use weight) to clean the hole from the web. If you live on the lower floors, then invite Jeck workers or contact a special service so that the channel be free before installing the fan.

Exhaust ventilation in the toilet. Installation features

In order to make ventilation in the restroom, it is necessary not only to buy the fan itself, but also auxiliary materials. The modern market of building materials offers buyers a wide range of various boxes and pipes for ventilation systems. It can be a box of different shapes made of thin metal, plastic, flexible material (pipes with aluminum spraying, corrugated plastic, flexible air ducts).

As an air duct organization, it is best to use rectangular or round devices. By the way, the rectangular shape of the ducts can be laid right on top, if you have already repaired and the tile is laid. The box is easily placed even behind the sewer riser.

It is best to make individual ventilation channels for a kitchen and a combined bathroom. Therefore, you need to purchase more adapters and connections.

We summarize: To lay the forced ventilation system, we will need:

• propylene tube 1 pc. For a combined bathroom and 2 pcs. for separate (separate to the restroom and bathroom);
• connecting element for combining a round duct with rectangular;
• fan;
• the grill for the ventilation channel;
• a socket with moisture protection or if you connect the fan to the lighting system, then an additional several meters of the electric cord;
• instruments.

If it is impossible to install the fan into the opening of the existing air duct, then it is necessary to think over in advance how the air duct will pass. It can be hidden under hinged ceiling. The best place for mounting the fan is right on the ceiling in the center. If the room is large, then it is best to install several fans, it is desirable that they are located closer to the bathroom or toilet to provide a good air flow in this place.

Look at the photo, it looks like a ventilation channel passing in the wall of the mine:

When choosing a fan, you do not need to be guided by such a rule, the more powerful the device, the better. Do not be lazy to calculate the area of \u200b\u200bthe room and repel from this figure. If you install a powerful fan in a small restroom, you can come to the opposite - the air flow will be less than the outflow.

With the work on the ventilation device in the toilet, you can cope with yourself, if your task is not to build an additional design of the air duct or corrugation. To do this, you only need to install the fan (it is best to buy a radial type) directly in the ventilation mine. Unscrew the grille located in the exhaust mine and insert the fan into it. For reliability, it is desirable to glue the device to glue. Next, you need to lay a box for connecting the fan to the power grid. You can display a separate outlet or hold the cable and connect directly to the lamp.

Now you know how to make ventilation in the toilet alone. In order not to occur during work, we offer to see this video. Footage:

Subtleties of work. What else do you need to know

To make the efforts are not spent in vain, it is necessary not only to choose the correct fan and install it, but also adhere to some rules:

• extract must be installed opposite the door to the bathroom. If you decide to install an exhaust device next to the door, on one wall, the air circulation will become weaker;
• do not forget to pre-clean the ventilation channel to get rid of garbage that fell from the attic or stuck in the mine's mine (pieces of plaster, etc.) After the repair works of the residents of the house;
• if you see that the ventilation channel is too narrow, then it can be expanded to increase the air flow. To do this, use the perforator. If the channel is wide, then in the hood you need to install a plastic tube, and the remaining space is filled with construction foam;
• extracts need to deepen completely into the mine so that only one lattice remains on the wall;
• "To plant" the fan can be on durable glue, sealant or fasteners. By the way, it is best to use glue or sealant, these materials will additionally improve sound insulation and reduce the vibration of the device during operation;
• connecting exhaust design to the power grid, you must hide the cable in a pre-prepared box. This is possible if the ventilation in the toilet is equipped at the initial stage during repairs in the bathroom. If the repair has long been made, and in order not to break the tile, the box for the wire is descended along the wall, laying in protection from plastic.

How to care for the fan?

It is necessary to care for the forced ventilation system. From time to time it is necessary to check "craving" in the toilet and the bathroom, as well as rinse the mesh against contamination. If the mesh is broken, the fan will not be able to work and even can be broken, so it is necessary to wash the grid with warm water with any detergent. Suitable liquid soap.
