Scheme of sewerage ventilation in a private house

For any scheme of sewerage ventilation in a private house, the main task is to protect the home from penetration into it of unpleasant odors, which can greatly spoil the life of all residents.

As you know, outdoor temperature rise, strong wind, and many other factors lead to the fact that the organic begins to decompose actively, resulting in a rather unpleasant smell, which becomes a serious problem if the private house is not equipped with an effective sewage system.

In addition, the sewage system is specially intertwined with water supply and heating systems, which in turn also in some individual cases lead to the formation of all kinds of stench.

The installation of the riser, other elements of the sewerage system, as well as of the heating and water supply systems, even at the design stage, should provide for the equipment in the private house of certain systems that will be responsible for removing all the stench into the atmosphere.

In any case, the ventilation of the sewage system in a private house must be equipped according to all rules and in accordance with generally accepted norms.

Of course, the scheme and devices of the ventilation system in a private house have their own specifics, but with the right approach, they can be equipped in short time periods with their own hands.

ventilation systems The installation and installation of sewer ventilation is a prerequisite for any private home.

It becomes the barrier to the spread of all kinds of unpleasant smells coming from the risers of sewerage, water supply, and also heating.

For each riser in a private house, ventilation should be provided, in addition, in this case, a scheme may be provided in which all the risers will be combined into a common ventilation system. Sewerage scheme

At present, in order to equip in a private house the ventilation system of the sewer pipe, it is necessary to adhere to certain rules.

First of all, the pipe from the hood should be raised above the roof of the building no less than one meter.

In the case where the sewage, water supply and heating systems have one common ventilation, pipes of the same diameter should be used.

In addition, on the outlet part of the ventilation pipe, do not install the hood, since in winter the accumulated condensate on it can lead to the formation of a cork of ice.

It should be remembered that the sewage ventilation in a private house should in no case be combined with a chimney or with a common ventilation system.

It is not recommended to place the ventilation outlet from the riser a distance closer than four meters from the windows and balconies of the apartment building.

It is also not advisable to install the ventilation outlet in the immediate vicinity of the overhang of the roof, as it may be damaged if snow and ice falls in winter.

In order to ensure that the ventilation of the sewerage, as well as the heating and water supply systems could provide a comfortable living in the house, it is necessary not only to make it properly installed by one's own hands, but also at the design stage to provide all the subtleties and nuances of its work.

In any case, its installation should be carried out only after the exact number of risers and the location of all sewage elements are determined.

Nuances of designing

When designing sewage ventilation, special attention must be paid to the height of its output element.

It should be located as high as possible from the ground level and only then it will be possible to prevent water leakage from the hydraulic gates, to avoid the formation of air bubbles in the system, and also to eliminate the possible spread of unpleasant odors in the interior of the house.

The sewage system in a private house is best made using plastic pipes.

This is due to the fact that these pipes have a relatively small weight, their installation is simple and fast, in addition, they are equipped with all the necessary connectors.

Even at the design stage of the house, it is mandatory to provide in its design a special ventilation duct through which the sewer system will pull the pipes out.

In the event that in the sewer system of a private house, for any reason, during the design, the installation of the ventilation pipe was not envisaged, its output can be carried out on the external wall, while covering it with a special decorative socket.

If the construction of the house is conducted in areas with sufficiently severe climatic conditions, the sewage ventilation scheme must necessarily provide for the possibility of insulation of the pipe in order to avoid icing.

Very often it happens that it is not possible to equip quality ventilation of sewerage, heating, and water supply systems for any reasons, in this case, the installation of a special vacuum-type valve can become a way out.

Vacuum valve arrangement

Vacuum valves enable quick and efficient installation of ventilation for sewerage, heating, and water supply systems.

Their installation is carried out directly at the very end of the sewer riser, coming from the house.

This element is a certain size device, inside of which is a spring with a small resistance.

This valve has a rigid hermetic seal, which prevents air penetration.

In the event that the discharge of gases occurs in the risers of the sewage system, this device operates and opens, thereby allowing airflow from the relevant room directly into the system itself.

Then the pressure in the system begins to gradually equalize, which leads to the reverse operation of the spring and, accordingly, the closing of the valve itself, which in this way prevents unpleasant smells from entering the interior space of the house from the risers.

Of course, such vacuum valves can not fully replace the full ventilation of the sewer.

The fact is that over time they are clogged, which is the main reason for their failure.

It should be noted that such devices can not prevent the spread of an unpleasant odor if there are no water in the siphons that are installed on the various plumbing fixtures.

Of course, such valves in some individual cases help to eliminate unpleasant smells from the sewer, however, in order to completely get rid of this problem, still need a full sewage ventilation.

The design and installation of such a ventilation system should be approached with full responsibility, using only quality components and materials.

Features of the ventilation system

In order for the ventilation of the sewerage to work properly, it is absolutely necessary to use the risers.

It should be noted that if there are several separate risers in the house, their ventilation scheme is best combined into one.

The normal functioning of the sewage system in a house depends largely on its connection to the atmosphere.

Only if the sewer pipes have the correct ventilation connection with the outside airspace, they will not form air bubbles and there will be a depressing that interferes with the normal functioning of the entire system.

It should be remembered that the diameter of the pipe from which the sewage ventilation is collected should not be less than the diameter of the pipe from which the sewer riser itself was assembled.

The most optimal option to equip sewer ventilation in the house with their own hands is to supply each individual riser with its own pipe and a special deflector.

However, this option is quite expensive, and therefore not always available, so the most common sewer ventilation is common, combining in one single system several risers at once, which has one outlet to the ventilation pipe.

For this purpose, take a pipe with an increased diameter, which will be able to effectively cope with its task and prevent the ingress of odors into the interior of the house.
