Internal sewerage. Mounting Features

The system of pipelines connected to sanitary equipment is called "internal sewerage". In each building of a modern type, the internal sewerage network is planned. The purpose of the equipment is to collect off-shore waters and divert them from the structure to a centralized or autonomous sewage system.

Internal sewerage in a private house. Furnishing

The laying of individual sewerage should begin with preparatory work:

1. Drawing up a communication scheme.

2. Preparation of marking on the walls and floors of the building.

3. Preparation of depressions and channels for concealed wiring.

Pipes for the assembly of the house network will suit cast iron or plastic. The diameter of the risers is usually 100 mm. With the same diameter of the pipes, the internal sewage system is arranged from the toilet bowl to the entrance to the riser. From the bathrooms, washrooms, shower cabins, pipes with a diameter of 50 mm are installed.

Internal sewerage. Installation

Sewage in the house is recommended to be carried out after it is arranged outside, with a factory in the house of the exhaust pipe (on the first floor or in the basement room). In this case, the risk of inconsistencies between the two networks is eliminated. In the absence of such an opportunity, the installation of the system must begin, leaving a significant area before the release is not yet ready. Although any manipulation depends on the specific conditions. Adhering to such recommendations, it will be possible without great difficulties to connect communications into one common network.

The horizontal sections of the system should be laid strictly in a straight line, avoiding distortion of the gradient. The direction of the pipeline can be changed with the help of a fashion. Vertical sections of the system are mounted without fractures in the socket. If the scheme requires the installation of a fittings, the installation of the pipe is performed with the component already inserted and fixed.

Setting the angle of the network on a horizontal surface is performed using a special tool (level).

Internal sewerage of the individual house with a turn to a right angle in the floor construction is assembled from two plastic knees with an angle of 45 degrees. It is also possible to use cast-iron bends in the number of two pieces and an angle of 135 degrees. In order to eliminate the formed clogs in the sewage network, use a plastic tee or a cast-iron tee with a 45-degree angle with a plug.

The branch pipelines of the internal network in the private house, located under the ceiling, in the basement are connected to the risers by means of crosses and slanting tees.

During the discharge of effluents, as a result of discharging in the sewage pipes, water can be sucked from the siphons of sanitary equipment into the sewage system. Such action leads to penetration into the room of unpleasant odors. In order to avoid a negative situation, you should install a fan (exhaust pipe). It is removed to a height of 70 cm through the roof.

Internal sewerage of PVC

It is worth noting that when modern sanitation is arranged, the advantage is usually given to PVC pipes. They are of good quality, resistant to aggressive environments. Wastewater contains many aggressive chemicals. Therefore, it is recommended to purchase PVC material. The quality of the pipes ensures a long service life. High physical properties are manifested in the period of sharp temperature changes. In addition to the above advantages, there are a number of positive qualities of PVC sewerage:

1. Low coefficient of thermal expansion.

2. Low flammability, propensity to self-extinguish.

3. High level of noise protection.

4. Thermal resistance.

5. Durability (up to 50 years).

6. Ease of installation.

7. Safety for human health.

To date, the use of PVC pipes is very wide. They are used both in multi-storey buildings and in private houses. Among other things, their cost is relatively small.
