Several decades ago private houses did not have toilets. To meet their natural needs, people had to cope with the need for a street toilet. It was a small building, which always smelled bad. Now, in the world of modern technology, toilets began to equip in homes. It is very comfortable, because in the cold weather you do not need to run to the toilet several times a day. Naturally, in a private house or apartment, the bathroom should be equipped with everything necessary to prevent the spread of smell throughout the house and prevent the formation of mold. Therefore, every modern toilet must be equipped with a ventilation system.

Ventilation in the toilet. Types of

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

Types of ventilation in the toilet:

  1. Natural.
  2. Forced.

The first option says that air circulates through the room on its own. Such ventilation is installed immediately during the construction of the house, and consists of several air ducts and shafts, located vertically between the walls. Mines lead not only to the toilet, but also to the bathroom, and also to the kitchen. Holes or entrances to the ventilation shaft are protected by lattice panels, and airflow into the kitchen and bathroom is through the openings located in the house, and through open windows and doors. Natural ventilation in the toilet of a frequent home does not always cope with the tasks, as the size of the house and the layout may not meet the established standards. It happens that there is no bathroom in the house( old houses of "Khrushchev" and "stalinka") and there is no sewerage. Therefore, tenants independently equip one of the rooms for a toilet and a bathroom: lay a sewer pipe, think out where it is better to make a cesspool( or connected to a central sewage system), install 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 spreads quickly throughout the house. To prevent this, you can install forced ventilation. But before you know the benefits of forced ventilation in the bathroom and how to organize it correctly, let's find out if the ventilation in your toilet works well.

How to check the ventilation in the bathroom

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

  1. Open the toilet door.
  2. Open the window for ventilation or open the window.
  3. Take a paper towel and attach it to the vent hole.
  4. If the ventilation functions normally, the napkin will be pressed firmly against the grating hole. If this does not happen, it is possible that the ventilation duct is clogged or there is none at all( the ventilation shaft is immured).
  5. You can light a match instead of a napkin or turn on the lighter and immediately bring it to the vent. If the flame does not move, then the ventilation in the bathroom does not work.

If you see that the flame of a lighter or a candle is deflected towards the shaft and even fades, this indicates that the ventilation is normal. By the way, in summer, when it's very hot in the street, the air in the ventilation duct remains stationary, this will make checking difficult.

Now you need to close the window or window, as well as the doors and check the draft in the ventilation duct again. So you can understand the need for additional ventilation. According to experts, in any case, it is necessary to install compulsory ventilation in the toilet and bathroom( especially if the bathroom is combined).Then the room will always remain dry, it not only creates comfortable conditions in the living rooms, but also keeps in proper order the plumbing and furniture in the toilet and bathroom.

Forced ventilation in toilet

This type of air intake in the toilet is more suitable for multi-storey buildings. If you install a forced ventilation system, you can solve a problem such as severe unpleasant air in the room. It is especially important to install the ventilation system in the case when the natural channel of the air intake system in the bathroom is connected to the common one. To prevent the spread of odors from neighboring apartments, it is necessary to install a fan that has a non-return valve. This scheme will also cope with unpleasant flavors, if the toilet and 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 items. This is not easy, since it is necessary to understand what the power of the device should be. To do this, multiply the area of ​​the toilet by the height of the ceiling. The figure is the volume of your room, in which you must install forced ventilation. Now this figure needs to be multiplied by the rate of air exchange, the productivity of the device will be 1 hour. For the toilet there are certain norms, this is 25 m3 per hour. Depending on the area of ​​the room, this figure may be greater.

How to choose the right fan:

  • noiselessness of the device. Choose models with output up to 40 db, as this noise level does not affect human hearing and does not interfere with the normal rhythm of life;
  • buy 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 in the bathroom.

Another important thing is the availability of additional functions in the device, for example, the 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 turns on automatically, when the person leaves the room, the fan still 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 5 more minutes, and then it will turn itself off.

There are such models of fans that can be connected directly to the switch. When the light in the lavatory is turned on, the device for air ventilation is also started. Once the light is turned off, the fan also stops working. If there is no natural ventilation shaft in your bathroom, you can connect the fan to the mine in the kitchen, only then you need to buy and install a grate with a valve so that the fan pumps up the air where necessary. A non-return valve will prevent 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 in the room. If you went to take a shower in a shared bathroom, then such a fan will turn on independently, as the humidity in the room will rise.

Ventilation in the toilet with their own hands

The design of the fans can be different:

  1. Axial - the air flow is pumped by the fan blades, passing along its axis. Air pressure to a maximum of 50 Pa. Such fans can only be installed in non-ducted ventilation systems.
  2. Diametric, when the main wheel of the fan looks like a drum. Unfortunately, despite the attractive price, the performance ratio of fans of this type is not high.
  3. Centrifugal fans are equipped with a spiral housing. They are considered the most effective and high-performance. Of the shortcomings can be identified only one - this is a high level of noise when working.
  4. Mixed - axial with centrifugal. Such a fan has good performance, it works noiselessly, it has small dimensions.

Once you have determined the type of device for forced ventilation, you must perform the prevention of the vent channel. A variety of debris can enter the ventilation hole, for example, from the attic. In addition, it is quickly clogged with a web, on which particles of dust gradually settle. All this interferes with the natural circulation of air.

If you live on the last floor, you can clean the ventilation shaft yourself. To do this, simply lower on a stiff rope any heavy object( many use weight) to clear 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

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 customers a wide range of different boxes and pipes for ventilation systems. It can be boxes of different shapes made of thin metal, plastic, flexible material( pipes with aluminum sputtering, corrugated from plastic, flexible airway channels).

As the organization of the duct, it is best to use rectangular or circular devices. By the way, rectangular ducts can be laid directly on top, if you have already made repairs and laid tiles. The box easily fits even behind the sewer riser.

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

Let's sum up: for a 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 circular duct with a rectangular;
  • fan;
  • grating for ventilation duct;
  • socket with moisture protection or if you connect the fan to the lighting system, then in addition several meters of electric cord;
  • tools.

If it is not possible to install the fan in the hole of an existing duct, then it is necessary to think in advance how the duct will pass. It can be hidden under a curtain ceiling. The best place for mounting the fan is on the ceiling in the center. If the room is large, then it is best to install several fans, preferably they are located closer to the bathroom or toilet, in order to ensure a good airflow in this place.

Look at the photo, the ventilation channel that passes through the shaft wall looks like:

When choosing a fan, do not follow such a rule, the more powerful the device, the better. Do not be too lazy to calculate the area of ​​the room and start from this figure. If you install a powerful fan in a small restroom, you can come to the opposite - the airflow will be less than the outflow.

With works on the device of ventilation in the toilet, you can manage on your own, if your task is not to construct an additional duct design from plastic or corrugated tubes. To do this, you only need to install a fan( best to buy a radial type) right in the ventilation shaft. Unscrew the grille located in the exhaust shaft and insert the fan into it. For reliability, the device should be glued to the adhesive. Next, you need to lay a box to connect the fan to the mains. You can output a separate outlet or cable and connect directly to the luminaire.

Now you know how to do ventilation in the toilet yourself. That there were no questions during work, we suggest to look this video:

Subtleties of work. What else you need to know

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

  • hood must be installed opposite the door to the bathroom. If you decide to install the exhaust device next to the door, on one wall, then the air circulation becomes weaker;
  • do not forget to pre-clean the ventilation duct to get rid of debris that has fallen from the attic or stuck in the shaft hole( pieces of plaster, etc.) after repairing the tenants of the house;
  • if you see that the vent hole is too narrow, then it can be expanded to increase airflow. To do this, you need to use a puncher. If the channel is wide, then a plastic pipe should be installed in the hood, and the remaining space should be filled with construction foam;
  • the hood should be deepened completely into the shaft so that only one grate remains on the wall;
  • "plant" the fan can be on a strong adhesive, sealant or fasteners. By the way, it is best to use glue or sealant, these materials will further improve the sound insulation and reduce the vibration of the device during operation;
  • connecting the exhaust design to the mains, it is necessary to hide the cable in a prefabricated box. This is possible if the ventilation in the toilet is equipped at the initial stage during the renovation in the bathroom. If the repair has been done for a long time, and not to break the tile, the wire box is lowered along the wall, stacked in plastic protection.

How do I care for a fan?

You have to take care of the forced ventilation system. From time to time, it is necessary to check the "cravings" in the toilet and bathroom, and also to clean the mesh from contamination. If the net is clogged, the fan will not be able to work and can even break, therefore it is necessary to wash the mesh with warm water with any detergent. Suitable liquid liquid soap.
