Ventilation in the bathroom and toilet: how to make your own hands?

To maintain human health, it is not enough to monitor the quality of food and liquids consumed by it. Great attention should be paid also to the air in our premises. Unfortunately, few people think about the fact that it is as important as good food and water.

That ecological situation, which is formed in the gassed large cities, does not allow their residents to banal airing the premises. The most acceptable solution to this problem is the installation of ventilation. The influx of clean air will reduce the likelihood of headaches, dizziness, drowsiness, and also serve as a prevention of allergies.

The need for ventilation in the bathroom

In the construction of residential buildings, ventilation in the bathroom and toilet is usually installed as natural. However, it is clearly not enough to constantly ensure a normal level of freshness and cleanliness of air in these rooms. So, when taking a shower, the bathroom immediately becomes filled with steam. Due to the lack of a normal air exchange, moisture settles on the ceiling and walls. In the future, this factor will affect the appearance of black spots and mold. And this is very harmful to health.

Mold spores in the air of the bathroom can settle in the human lungs and cause diseases such as allergies, asthma, etc. In addition, black spots gradually destroy the finishing materials, reaching the very concrete. That's why you need to install a normally functioning ventilation system in your home to everyone.

Check of serviceability

It also happens that the natural ventilation in the bathroom and toilet works quite normal. That is why before installing a new system, it is necessary to check the serviceability of an existing one. It is not difficult to do this. In addition, no additional tools are needed for this. It is enough to bring a scrap of paper directly to the grille. The sheet must adhere to it under the action of moving air. If this does not happen, then we can say that the hood does not work. Sometimes the reason for this condition may be too dense door to the bathroom or toilet. In this case, the flow of air into the bathroom is not ensured in the required volume. This also requires verification. If the hood works when the door is closed, but when it is not open, you can simply make a gap between the floor and the door leaf.

The principle of the ventilation system

Air exchange in private cottages and apartment buildings is carried out according to different schemes. In small residential buildings, separate ventilation ducts are removed to the roof from the kitchen, toilet and bathroom. Another scheme is designed in homes. Here the air is collected in one common channel, which is output to the roof. If the house provides forced ventilation, the builders install special systems equipped with sensitive elements. Such equipment closes or opens the shutters when it becomes necessary.

When should I install artificial ventilation?

The operation of air-exchange systems installed in the house can fail if:

- errors in the design or installation;
- accumulation of debris in ventilation ducts;
- damage to the system during repairs, etc.

Fan selection

Before installing a forced air exchange system, the required device must be purchased. He is an electric fan. When choosing this device, pay attention to:

• Noise level during power-on (it should not be above 30 dB);
• The power of the device (selected depending on the area of the room).

It is necessary to determine and with the place where it will be installed. It should be away from any electric heaters. The ventilation system of the bathroom is equipped with high-quality insulation of used electrical wires. This caution is caused by the increased humidity level in the room.

Types of fans

These devices can be of the following types:

• Connecting to switches (their work is carried out only when the room lights up);
• The sensors are equipped with sensors (they are switched on automatically if the humidity is exceeded);
• With a timer that sets the time for their work.

Forced ventilation in the bathroom and toilet is arranged using various models of appliances. And each of them has its own design features. So, fans are:

1. Axial (propeller). This is the simplest model.

2. Radial. This type of device is able to provide high pressure in the room.

3. The diagonal. This model combines the functions of the two previous ones.

4. The diametric. These fans are able to work with a large volume of air due to the passage of air flows along the perimeter of their wheels.

The device of the new system

Forced ventilation in the bathroom can be done by yourself. And the work of special complexity does not represent. First of all, it is necessary to check the air vent and clean it, if necessary, from debris. For someone who can not install a new fan, another option is recommended. You can simply remove a few meters of the new channel from the old canal, by purchasing appropriate materials in the building store.

When installing an electric fan, you should determine the place where it is best to install it. Ideally, it should be a wall facing the door.

The fan is mounted directly into the opening of the exhaust duct. If your device has a larger diameter, then the opening will have to be slightly expanded. After this, all electrical wires must be carefully connected. They should be placed in a dry place (so that they are not visible). At the next stage of work the device is connected to the switch and fastened together with the grate to self-tapping screws or liquid nails.

Exhaust system options

As a rule, the channel through which ventilation is provided is located in the toilet. The scheme of air exchange between this room and the bathroom can be carried out in two ways. The first of these involves laying a separate vent pipe. It should be located in the ceiling area and go from the bathroom to the air vent. The second option involves the installation of two separate fans.

One of them should be located on the air channel, and the second - in the wall between the toilet and the bathroom.

Most often, ventilation in the bathroom of the "Stalin" is arranged according to the first option. The height of ceilings in such apartments, which is 3-3.5 m, contributes to this decision. Forced ventilation in the bathroom is carried out by laying an additional air duct. This construction is fixed under the ceiling and is closed with plasterboard. In this case, ventilation in the bathroom is carried out using a flexible, rigid or semi-rigid duct.

Ventilation in the toilet

Quality air exchange is important not only in the bathroom. Normal circulation of air is necessary and in the toilet. It will allow not to feel discomfort from the sewer system and prevent the appearance of fungus, reducing the humidity in the room. It often requires artificial ventilation in the toilet of a private home. This need arises if there is no natural air circulation due to the lack of sufficient wind speed in the area where the dwelling is located, high ambient temperature and some other factors.

How to make ventilation in the toilet (forced type)? For this, it is necessary to study the scheme of the device of the existing air duct. Sometimes he can have an exit directly to the toilet. But often the ventilation in the bathroom and toilet comes from a single box in the bathroom. In this case, between these two rooms there must be a hole enclosed by a grate.

In the first case, it is possible to install the fan directly on the box. In the second version of the exhaust system, an additional air duct will be required.
