How to lay a sewer in a private house correctly

For comfort in any private home is very important is the proper operation of the sewer system, ensuring the removal of wastewater and their treatment, if necessary. Such a system is divided into internal or external parts and includes a septic tank, which is used for processing and further use of wastewater.

How to lay sewers in a private house, each owner decides for himself, the main thing in this process, to pay the closest attention to each stage of the work, and not to forget to check the tightness before starting use.

In addition, it is necessary not to forget about such a mandatory element of this system, as ventilation, located above the roof level, which will avoid unpleasant odors from plumbing fixtures.

Sewer wiring

In order for the sewage wiring in a private house to be organized correctly, it is necessary first to think over the pipeline laying scheme and calculate the required amount of materials.

For arrangement of sewage system you will need the following materials:

• Plastic drain pipes;
• Connecting fittings;
• Plumbing equipment for sewage in a private house;
• Pipe fasteners;
• Insulation;
• Adapters;
• External pipe laying;
• Septic tank;
• Filters.

Before taking up the laying of the pipeline, you need to decide where it will be led - to the septic tank or to the central sewer pipe.

Note! Of course, the central system is the most economical option, but it is not always possible to connect to it.

If there is no sewage near your site, then it will be necessary to choose a septic tank that is most suitable in terms of volume. The dimensions of such devices are selected based on the number of users of the system and the intensity of its use.

So, for example, for a family of only 3-4 people to stay in the country in the summer will be enough just a cesspool. But if we are talking about sewage for a house in which a large family will live year-round, then you have to buy a good PVC septic tank, endowed with a drainage filtration system.

From the scheme to the construction of wells

It is important to determine what type your system will be - gravity or forced. For a country house, a self-flowing type system will suffice, in which the drains move independently from the place of release to the receiver itself.

Those who ask questions about how to build sewers in a private house competently, should understand that the construction of such a system should be started from the inside.

The sequence of internal installation work is as follows:

1. The marking of installation sites of sanitary devices and points of entry of drains into the system is made;
2. The internal pipeline is laid taking into account the difference in pipe diameters and the required slope from each point of reception of effluent.

The diameter of the pipe is selected as follows:

• Diameter 5 cm, slope 0.025 - sink, sink, shower, toilet;
• Diameter 2-3 cm, slope 0.2 - washing machine, dishwasher;
• Diameter 4-5 cm, slope 0.02 - wash basin;
• Diameter 5 cm, slope 0.02 - bathroom, bidet, urinal;

1. Pipe connections are made using fittings that can be made in the form of crosses, tees or couplings. When making connections, do not forget to take into account also the magnitude of the loads that will be applied to the pipeline;

Council Pipe connection angles must not exceed 90⁰, and crosses, etc. -45⁰.

1. One of the risers of the system must be brought out, above the level of the roof:
2. Pitched roof - 0.5 m;
3. Flat unexploited roof - 0.3 m;
4. Flat operated roof - 3 m;
5. In the presence of cutting edge ventilation system - 10 cm;
6. Installation of sewage in a private house is carried out in the grooves made in the walls or in the floor.

Council It is imperative to ensure the presence of the hatches so that it is possible to monitor the state of the system and repair it, if necessary.

Installation requirements for the exterior of the system

External sewage system is a system that includes the pipeline from the house to the septic tank or central sewer network. Before undertaking the laying of an external or outdoor part of the sewer system, it is necessary to perform a schematic drawing.

In this drawing it is necessary to consider the following important points:

• The width of the pipeline trench should exceed the diameter of the laid pipe by 20 cm;
• The depth of the pipeline is selected below the level of soil freezing;
• The minimum slope of the lines to be laid should be 0.7.⁰ on 1 meter of the pipeline, and maximum makes 15⁰;
• The pipe is laid on a sand pillow consisting of sand and gravel, carefully tamped at the bottom of the dug trench;
• In order for the system to be laid correctly, close attention should be paid to thermal insulation.

In addition to the pipeline in the sewage of the house there is often such a septic tank as a cesspool. For its construction digging hole of the required size. The walls of such a pit are laid out with bricks or poured with concrete raster.

It is necessary to make a double roof for it from wooden heat-insulated shields. It is also necessary to equip sewer ventilation for this construction.

Despite the simplicity of the arrangement, the cesspool is an uneconomical design, since it requires constant emptying.

Note! The best and more profitable option for arranging an autonomous sewage system in a private house is to purchase a septic tank, even though the price of such products is rather big.

Similar designs are produced from different materials and come in various sizes. They are able to provide high-quality work, unpretentious in service, and do not create unpleasant aromas around themselves.

Pipeline arrangement

Let's take a look at how to properly equip a sewage supply to a private house with your own hands. Particular attention should be paid to sewer lines.

To organize the withdrawal and movement of effluent should take into account the following points:

• The outdoor pipe exit should be above the ground level and should be provided with proper thermal insulation;
• External laying of sewage pipes in a private house should be carried out taking into account the fact that plastic products need protection from the damaging rays of the sun. That is why experienced experts recommend the use of heat-insulating materials or metal housings.
• In some cases, they even use cast iron pipes for this section, but modern builders have abandoned this heavy material. In this regard, the installation of sewage of a private house made of plastic pipes becomes not only easier, but also much more economical.

Tests of the finished system

Before starting the operation of the created system, each experienced master performs its tests to determine its efficiency and safety.

The instruction of such tests consists of only two points:

1. The first stage of testing is carried out at the pipeline installation stage.. To do this, first all the lines fit without sealing rings. At this stage, it is necessary to ensure the correctness of the installation of the system itself and the literacy of the docking of its elements. Also at this stage is determined by the need to use when installing additional reinforced fasteners;

1. The second stage of the test occurs when the system is already fully assembled, but trenches dug for its installation have not yet been filled.. Such tests are performed under conditions of maximum load on all components of the system. As a result of such a check, problems that need to be eliminated as well as leaks of the sewer system are identified.

In addition to these tests, it is necessary to make a mandatory visual inspection, which will allow to identify the defect in the system and damage to the pipeline. If, after a detailed inspection, you are convinced that the system is working properly, then it will be possible to install the plugs and start its filling and further operation.

Finally

Sewerage, as part of the comfort of living in the house - is a complex system that requires special attention and care during the installation process. When constructing such a system, it is necessary to immediately take into account the level of load on it during operation, as well as to consider ways to drain wastewater from the building or site.
