sewer ventilation

sewer ventilation-To a private house, surrounded by beautiful nature, life was comfortable and easy, recommended time to address the issue of air ventilation. Ventilation sewage – a special ventilation outlets for the air that comes from the sewer system of the house. Such a device requires sanitation, especially in order to remove from said system of unpleasant odors, and substances that contain unfavorable elements for human health.

The best option sewer ventilation for a country house can be called a device that allows you to display the ventilation outlets on the roof. However, if we are talking about air ventilation in buildings several stories high, it makes sense to install the exhaust portion of the risers, which can be placed next to the sewage internal systems.

During the installation of a ventilation device drain, which is located inside the premises, it is recommended to use a method such as the installation of exhaust pipes, which, in fact, would be a continuation of the existing sewer risers. In this case, experts advise to use the established and practiced regulations. Thus, in the case exhaust pipe mounted on flat roofs, they should be displayed above the roof level of about 30 centimeters. In that case, if the work is performed at an unfished pitched roof, the height of the pipe must exceed the distance from the surface by about 50 centimeters. In that case, if the work is done on a flat and actively maintained roof, the chimneys that remove odors, should be raised above the roof about 300 centimeters.

Sewer ventilation can also be set by using one of several basic types of ventilation outlets. The first way – is the so-called non-insulated version. In most cases, the diameter in accordance with the standards of the order of 110 millimeters. The second version of this release – insulated and insulated pipes. Inner diameter of such ventilation is also about 110 millimeters, external – about 160 millimeters. In compliance with the height of both outputs equal to 500 millimeters.

In organizing sewer ventilation specialists recommended to keep in mind that quality equipment outputs should not be used deflectors. In most cases, their use can cause condensation, that at low temperature, may cause freezing of the baffle openings. Location of sewer outlets for maximum efficiency should be carried out evenly over the riser. In the event that it becomes necessary to connect the inlet and outlet pipes, it makes sense to do this work using corrugated adapters.

Often in the kitchen, in the bathroom or in the bathroom, you may receive a characteristic odor, the cause of which lies in the fact that in the process of moving through the riser water capture air through the exhaust. However, if the supply air volume in the riser is less than that provided under the established standards, it begins to form a vacuum, which subsequently can cause the appearance of receivers sewage troubles such as the failure of the hydraulic valves. If you want to install the ventilation, and, at the same time, save money, the output – this arrangement unventilated risers. In the context of the fact that the diameter of the unventilated risers is 100 millimeters, its working height from the lower bend of the pipe to the upper part should be no more than seven meters.
