How to do ventilation in the toilet

A few decades ago, there were no toilets in private houses. To satisfy their natural needs, people had to celebrate the need for a street toilet. It was a small structure in which it always smelled bad. Now, in the world of modern technologies, toilets began to equip in houses. This is very comfortable, since in the cold one you do not need to run out into the toilet several times a day. Naturally, in a private house or apartment, the bathroom must be equipped with everything necessary in order to exclude the spread of the smell throughout the house and prevent the formation of mold. Therefore, each modern toilet should be equipped with a ventilation system.

Ventilation in the toilet. Types

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

Types of ventilation in the toilet:

1. Natural.
2. Forced.

The first option suggests that the air circulates the room on its own. Such ventilation is equipped immediately during the construction of the house, and consists of several air ducts and mines located vertically between the walls. Mine leads not only to the toilet, but also to the bathroom, as well as to the kitchen. The holes or entrances to the ventilation shaft are protected by lattice panels, and the air flow into the kitchen and 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, since the size of the house and the layout may not meet the established standards. It happens that there is no bathroom in the house in the house (the old houses of Khrushchev and Stalin) and the sewage system is not provided. Therefore, the residents independently equip one of the rooms for the toilet and the bathroom: they lay a sewer pipe, think about where it is better to make a cesspool (or connect to a centralized sewage system), install a plumbing and conduct water pipes. Everything 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 advantages of forced ventilation in the bathroom and how to organize it correctly, let's find out if ventilation is functioning in your toilet.

How to check ventilation in the bathroom

To find out if ventilation works in rooms such as a bathroom, a kitchen and a toilet, you can make the following:

1. Open the door in the toilet.
2. Open the window to ventilate or open the window.
3. Take a paper towel and attach it to the opening of the ventilation channel.
4. If the ventilation functions normally, then the napkin sniffs tightly to the lattice hole. If this does not happen, then perhaps the ventilation channel is clogged or it is not at all (the ventilation shaft is walled up).
5. Instead of a napkin, you can light a match or turn on the lighter and immediately bring it to the ventilation hole. If the flame is left without movement, then the ventilation in the bathroom does not work.

If you see that the flame of a lighter or candle deviates to the side of the mine and even goes out, this indicates that ventilation is normal. By the way, in the summer, when it is very hot on the street, the air in the ventilation channel remains motionless, this will make it difficult to check.

Now you need to close the window or window, as well as the doors and check the traction 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 bathroom (especially if the bathroom is combined) to establish forced ventilation. Then the room will always remain dry, this not only creates comfortable conditions in living rooms, but also retains plumbing and furniture in the toilet and bathroom properly.

Forced ventilation in the toilet

This type of air flow in the toilet is more suitable for multi -storey buildings. If you install a forced ventilation system, you can solve such a problem as heavy unpleasant air in the room. It is especially important to establish a ventsistem and when the natural channel of the air supply system in the bathroom is connected to the common one. To exclude the spread of odors from neighboring apartments, it is necessary to install a fan that has a check valve. Such a scheme will allow you to cope with unpleasant aromas if the toilet and the bathroom are combined.

How to do ventilation in the toilet

First you need to go to a specialized store and purchase a fan, as well as related elements. This is not easy, as you need to understand what the power of the device should be. To do this, multiply the area of \u200b\u200bthe toilet by the height of the ceiling. The resulting figure is the volume of your premises in which it is necessary to establish forced ventilation. Now this figure needs to be multiplied by the frequency of air exchange, the productivity of the device in 1 hour will turn out. There are certain norms for the toilet, it is 25 m ³ per hour. Depending on the area of \u200b\u200bthe room, this figure can be larger.

How to choose the right fan:

• the noiselessness of the device. Choose models with a production of up to 40 DCB, since such a 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 will last a long time;
• consider the following: the level of humidity in the room, whether the bathroom is combined, whether there is a shower cabin in the bathroom.

It is also important the presence of additional functions in the device, for example, a time delay timer. This is very convenient - you do not need to turn on the fan every time you enter the toilet, just open the door and the fan will turn on independently when a person leaves the room, the fan works for several minutes, and then automatically turns off. You can program the device and set the required operating time. Suppose, after you leave the restroom, the fan will work for another 5 minutes, and then will turn off on its own.

There are such fan models that can be connected directly to the switch. When the light in the restroom turns on, the air ventilation device is launched. As soon as the light is turned off, the fan also stops working. If your bathroom does not have a natural ventilation shaft, then you can connect the fan to the shaft in the kitchen, only then you need to buy and install the grate with the valve so that the fan is pumped air where you need. The check valve will not allow air to enter the kitchen.

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

DIY ventilation in the toilet

The design of fans can be different:

1. Axial - air flow is pumped out with fan blades, passing along its axis. Air pressure to the maximum - 50 PA. Such fans can only be installed in non -channel ventilation systems.
2. The diameter, when the main wheel of the fan looks in the form of a drum. Unfortunately, despite the attractive price, the productivity coefficient of this type of type is low.
3. Centrifugal fans are equipped with a spiral case. They are considered the most effective and high -performance. Of the shortcomings, only one can be distinguished - this is a high level of noise during operation.
4. Mixed - axial with centrifugal. Such a fan is good, it works silently, has small sizes.

Office:

After you decide on the type of device for forced ventilation, it is necessary to prevent the air supply channel. Different garbage can fall into the ventilation hole, for example, from the attic. In addition, he quickly clogs with a web, on which particles of dust 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, just lower any heavy object on a strong rope (many use a weight) to clean the hole from the web. If you live on the lower floors, then invite the employees of the housing office or contact a special service so that the channel is free before installing the fan.

Exhaust ventilation in the toilet. Features of the installation

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

It is best to use rectangular or round devices as the organization of the duct. By the way, a rectangular shape of the air ducts can be laid directly on top if you already have repairs and tiles are laid. The box is easily fit even behind a sewer riser.

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

We summarize: for laying the forced ventilation system we need:

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

If it is not possible to install the fan in the hole of the existing duct, then you need to think over in advance how the duct will take place. It can be hidden under a 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 ensure a good air flow in this place.

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

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

You can cope with the work on the ventilation device in the toilet, if your task is not to build an additional design of the duct made of plastic or corrugated pipe. To do this, you only need to install a fan (it is best to buy a radial type) right in the ventilation shaft. Unscrew the grill located in the exhaust shaft and insert the fan into it. For reliability, it is advisable to glue the device to glue. Next, lay the box to connect the fan to the mains. You can remove a separate outlet or draw a cable and connect directly to the lamp.

Now you know how to make ventilation in the toilet yourself. So that there are no questions during work, we suggest watching this video:

Subtleties of work. What else you need to know

So that the efforts are not spent in vain, it is necessary not only to choose the right fan and install it, but also adhere to some rules:

• the hood should be installed opposite the door in the bathroom. If you decide to install an exhaust device next to the door, on one wall, then the air circulation will become weaker;
• do not forget to first clean the ventilation channel in order to get rid of garbage that fell from the attic or stuck in the opening of the mine (pieces of plaster, etc.) after repair work by residents of the house;
• if you see that the hole of the ventilation duct is too narrow, then it can be expanded to increase the flow of air. To do this, use a perforator. If the channel is wide, then you need to install a plastic pipe in the hood, and fill the remaining space with construction foam;
• the hood must be deepened completely into the mine so that only one grill remains on the wall;
• You can “plant” the fan 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;
• by connecting an exhaust design to the mains, it is necessary to hide the cable into a pre -prepared box. This is possible if ventilation in the toilet is equipped at the initial stage during the repair in the bathroom. If the repair has long been made, and in order not to break the tiles, the box for the wire is lowered along the wall, laying in protection of plastic.

How to care for a fan?

It is necessary to care for the forced ventilation system. From time to time, it is necessary to check the “traction” in the toilet and the bathroom, as well as rinse the mesh from pollution. If the mesh closes, then the fan will not be able to work and can even break, so it is necessary to rinse the net with warm water with any detergent. Ordinary liquid soap is suitable.
