The device and the appointment of an internal drainage system

Species drainage systems

Conditionally drains can be divided into two types, each of which is used, depending on the design features of the roof and the type of construction:

• Outer;
• Inner.

external drain

device of this design enough simple, does not require special knowledge and skills.Mounting it made both during the construction phase and afterwards.The principle of operation of the sewage system is as follows: precipitation flowing down the roof to fall in the gutter, placed around the perimeter of the house at a slight slant.Going through these troughs, the water flows into the gutters and, passing through it, falls into drainage.

Internal drain

internal gutter is different from the external fact that the downspouts are located within the walls of the house.Waste water flows into these pipes at special funnels and, passing through it, running down the drain.Arrange a drainage system is much more difficult and sometimes even impossible, especially if the building is already constructed.The project is necessary to make such a structure so that the flowing water does not get on the wall.After prolonged exposure to moisture invariably lead to the formation of mold, and subsequently to their destruction.

device domestic waterflow

drainage system comprises many different components, each of which performs a specific task and is an integral part of the design:

• rainwater funnel, which is mounted in the lowest point of the roof;
• outlet pipe, which are intermediate between the funnel and riser;
• Risers, receiving wastewater;
• Underground pipelines transporting wastewater out of the house.

Gutters funnels consist of a body, grill and cover with holes.

By types are divided into:

• Bell, mostly iron - used for pitched roofs;
• Flat - horizontal tile or asphalt roofs;

outlet pipe and risers assembled from conventional plastic sewer pipes that connect to each other cement or asbestos-cement screed.Less commonly used steel and asbestos cement pipes.

Underground pipelines are constructed of reinforced concrete, asbestos-cement or ceramic pipes, but for apartment buildings often use cast iron pipes.

diameter craters, which discharge pipes and risers decision should be about 100-110 mm, which will ensure the free cross-flow of water at high intensity.

How to assemble gutter system - expert advice

following some basic rules and recommendations, installation of domestic waterflow did not take long:

• Try positioning funnel evenly over the entire surface of the roof;
• sure to provide a draft angle to the side of the funnel at least 2 degrees;
• 20 m- maximum distance between the craters;
• Places funnel and roof joints should be carefully sealed;
• return pipes must be installed through the premises, in which there is heating.

The main advantage of the internal gutter system is a lack of icing on the walls of the pipes in the winter, which may cause damage to the pipe.

to perform the installation of such a system is difficult, because such work requires a certain skill, because any error in the calculation or improper installation process can lead to leakage of water inside the building.

Today, such activities involved a lot of companies that have sufficient skills to perform such work.
