What should be the ventilation in the toilet

In the toilet, it is difficult to overestimate the importance of the ventilation system, the specific purpose of the room makes particularly stringent requirements for ventilation. In addition to aesthetic considerations, a well-designed ventilation system will make it impossible to develop mold in the toilet. That is why ventilation in the toilet of a private house, as well as in the bathroom of a city apartment, requires a serious approach.

Regulatory requirements

The main indicator of the operation of any ventilation system can be considered the volume of air passing through the pipe section per unit of time. It is on this indicator that you will need to focus on the design of air ducts in the bathroom.

In one way or another, ventilation systems are mentioned in many regulations.

In relation to latrines, attention should be paid to the following standards:

• SNiP 2.09.04-87 - it clearly states that a separate hood should be provided for latrines;
• SNiP 41-01-2003 - this document can be used when designing an air duct with your own hands. In particular, this standard prohibits laying of air ducts from latrines through other premises;
• SNiP 2.08.02-89 - useful when designing air ducts in public buildings and structures.

As for the ventilation power, it all depends on the number and type of plumbing fixtures. You need to focus on the following values: for the 1st urinal the norm is 25 m³/ hour, for a toilet bowl - 50 m³/hour. When ventilation is arranged in a private house for the bathroom, you can take the minimum value of 50 m³/hour.

Choose the type of ventilation

In the bathroom can be used either natural or forced ventilation. In the first case, the air moves due to the temperature difference at the inlet and outlet of the duct, and in the second - the fan installed directly in the duct, provides movement of air masses.

Supply and exhaust ventilation is found in bathrooms most often. In some apartments, the layout is designed so that the ventilation box is located directly in the toilet or bathroom, in such cases, even fiddling with the laying of horizontal ducts is not necessary.

Note! In the toilet, there may be difficulties with the supply of fresh air, so that you do not have to lay the intake duct, you can cheat a little and leave a gap between the door and the floor. The width of 2-3 cm will be quite enough, in this case, fresh air will flow into the toilet from the apartment.

In private homes in the summer due to the fact that the temperature outside is almost equal to the temperature inside the house, there may be problems with the burden. In this case, the installation of the fan in the duct is a necessary measure. In this case, the price of ventilation will increase slightly.

The simplest version of ventilation

Avid gardeners often have to deal with the fact that the ventilation in the dacha toilet is either absent or does not work satisfactorily. Of course, you can get used to the smell, but it is much easier to restore the system to work.

A classic summer lavatory is a lonely brick or wooden house located in a secluded place on a garden plot. The entire ventilation system in this case is reduced to the installation of several pipes.

Installation instructions for air ducts include the following items:

• be sure to ensure the flow of fresh air into the cesspool under the toilet. To do this, use the usual sewer PVC pipe 110 mm, one end is located directly in the cesspool, and the other rises above the roof of the toilet;

Note! If this is not done, then, firstly, the process of recycling will go slower (because bacteria also need air), and secondly, the unpleasant smell will leak into the booth.

• sometimes the ventilation of the sump is not enough, in which case you will have to install a simple supply and exhaust ventilation system of a pair of pipes;
• at the bottom of the toilet will be located inlet pipe. In order not to disfigure the appearance of the building, instead of a pipe, you can install an intake valve in the wall;
• in the upper part will be located the exhaust pipe, it will need to be brought out and raised above the roof.

Note! In the warm season, natural craving can be quite weak. Help in such a situation can install a vent on the duct, the efficiency of the system will increase by about 20%.

For convenience, the pipes can be laid along the back wall of the toilet, and fasten them with ordinary clamps. Everyone can cope with such ventilation of the toilet in the country with their own hands.

Ventilation of the toilet in the house

We have already decided on a source of fresh air - it will be a small gap left between the door and the floor. All that is left to do is to organize a normal air vent.

When it comes to how to make ventilation in the toilet at home, we can distinguish 2 cases:

• the ventilation box is located directly in the bathroom;
• he is in another room.

If the box is in the toilet - this can be considered good luck (although some of the free space is lost). In the section it can be seen that any box has 3 channels - 1 large section (common) and 2 smaller ones (separately for a toilet, kitchen). Due to this, the air from the toilet gets into its canal, rises about 3 meters upwards and only there it enters the mine, where it mixes with the air from other apartments.

Due to this, with normally functioning ventilation, the air from the toilet or from the kitchen will never get into another room. The ventilating box in a toilet allows to do without horizontal air ducts.

In private homes with toilet ventilation, things are much easier. Nobody bothers if you want to organize a separate hood specifically for the bathroom and bathroom and bring it to the roof. With this approach, even if the system fails, polluted air will not get into the apartment.

As for the general recommendations, you can advise, perhaps, not to use pipes of small diameter. Profile pipes are often used for air ducts; in this case, a 14x14 cm section can be considered the minimum recommended.

Verification and Troubleshooting

The efficiency of the ventilation system is checked by conventional means at hand. It is enough to bring a burning match to the exhaust pipe and observe how the flame behaves. It should deviate towards the lattice by about 45 ?, if it only slightly fluctuates, then the ventilation does not work at full strength.

For the purpose of testing, it is possible to attach an ordinary paper napkin to the lattice; it should be held on it by thrust. If you have the right equipment at hand, you can measure the force of thrust.

The most common problem with the operation of air ducts is observed in the case when the air does not start being pulled into the pipe, but vice versa. That is, the exhaust air duct begins to work as a supply air; this, to put it mildly, creates discomfort.

Remedies for this malfunction depend on the cause of the occurrence:

1. Too powerful hood - it is able to let the main part of the air in the apartment through the ventilation in a short time. Because of this, a small vacuum is created in the rooms and the air duct in the toilet starts to work as a supply air. To eliminate this problem, it is enough just to open windows in the apartment for the duration of the hood.

1. Neighbors could simply demolish the ventilation box, as a result of which there are problems with ventilation from the residents below.. Here you can only advise to contact law enforcement officers.

1. In frost, often icy air blows from the ventilation in the toilet.. The reason for this is the lack of influx in the apartment, with such a problem often faced after installing new glass. The only solution to the problem is the installation of inlet valves.

Note! Since in this case cold air will flow through the valves, you need to think about heating it. If there are no problems with heating, you can place the valve behind the battery, the air will rise along the radiator and heat up from it.

In conclusion

In the toilet, the importance of proper ventilation is beyond doubt. It is unlikely that someone will like it if very specific smells penetrate all the rooms in the house. In order to avoid the most common mistakes when constructing a ventilation system, simply follow the tips suggested in this article.
