Sewerage and its connection to the housing plan
To date, sewage is an integral part of a comfortable stay. But what if the apartment or house you bought does not have a sanitary sewer? In this case, it is necessary or hired a specialist to solve this problem, or solve it yourself. On the second option and will be discussed.
The sewerage system is closely tied to the layout of housing, so the first step is to draw up a scheme. It must be taken into account that all plumbing fixtures must be connected to a single pipeline. On it, the water will fall into the central sewer or cesspool. If the house or apartment is two-level, it will be necessary to make the risers.
Important! The layout of the sewerage system is the most important part of the work. In this connection it is better to entrust it to the engineer-designer.
When designing the wiring, the following points should be considered:
- Number of plumbing fixtures;
- Ways of water supply;
- Depth of ground freezing;
- Diagram of wiring in the apartment, house.
Calculating the slope angle of
The main problem of wiring is to make the pipes straight and arrange them with a slope. This bias is necessary for the fluid to flow in the desired direction. Also, the slope angle plays an important role in the self-cleaning of pipes. The slope of the pipes is calculated according to the following standards:
- Pipe diameter 40-50 millimeters - slope 3%;
- The pipe diameter is 85-100 millimeters - the slope is 2%.
So, for example, if the drain hole is located two meters from the point of entry into the riser, the sewage pipe for draining the water must be at a height of six centimeters with respect to the opposite end. The angle of inclination must be taken into account when installing each individual device. In this case it is necessary to take into account that, the further it is located from the central riser, the greater the slope.
Note! At the furthest points, it is recommended to install a washing machine and dishwasher.
Sewer installation
Having figured out how to draw up a scheme, it is necessary to consider how to make the sewerage layout and what materials to use for this. For these purposes, polyvinylchloride, polyethylene and polypropylene pipes are most often used. Cast iron pipes are rarely used, because plastic pipes are more durable and convenient to install.
The sewerage system is self-made simply. To do this, each piece of pipe from one end has a coupling. The other end of the pipe can be cut to the required length. Then the prepared segment is inserted into the sleeve of the other segment and tightly connected. Making corners in the system, it is better to use connectors at 45 degrees, and not at 90 degrees. This is due to the fact that at a direct angle the liquid can stagnate, while with a gradual rotation it will freely flow.
Sewerage in a private house with several floors and in apartment buildings consists of such elements: risers, collectors, exhaust pipes, a network inside the house and drain pipes from bathtubs, toilets, sinks. The layout for almost all buildings is the same: it starts from the kitchen, runs through the bathroom and toilet and connects to the common riser of the house.
Note! Over time, the pipeline from the impact of accumulation of dirt will decrease in diameter and possibly clog. In this regard, it is necessary to do the installation in such a way that it is possible to easily repair or replace the pipes.
