Replacement of sewerage in the apartment

As is known, the sewerage network is designed for drainage of water used for domestic purposes. Internal sewerage is a network of pipelines that are connected to sinks, toilets, baths and other equipment. For the organization of such networks, it is customary to use cast-iron or plastic pipes, as well as their combinations. Next, the replacement of sewerage using PVC pipes will be considered. The draining pipes from the shells have a diameter of 50 millimeters, and from the toilet bowls 100 millimeters.

It is worth saying that if the plastic sewerage began to leak after 5, rather than 50 years, it is due solely to errors when replacing it.

If it so happens that the plastic sewage system did not leak after 50 years, but only after 5, then it is usually not the pipes that are to blame, but the errors associated with the installation process. Since the installation technology assumes the observance of very specific rules, pipelines assembled with errors can not last for a long time. Before installing the pipes, they should be rinsed from the applied dirt and dust, then seal the seal with petrolatum, and then remove a small chamfer on the pipe that is inserted.

So, the replacement of sewerage requires compliance with very specific rules. Usually polymer pipes are made of polyethylene, polypropylene or PVC. The most common are the second and third species. In this case, for each material there are certain standards, since they have different characteristics, and here the thickness of the walls acts as the main parameter. In most cases, water enters the sewer system, the temperature of which does not exceed 95 degrees, so the pipes should be designed for use in this mode. While polypropylene is very resistant to temperature effects, they have a higher rate of linear expansion, which is not very good for sewer pipes.

Replacement of sewerage begins only after all the necessary fences have been made, depressions in walls and ceilings, holes have been made, and works connected with open fire have been completed. Installation usually starts from the outlet, after which a riser is assembled from the bottom upwards and the bends are installed. The sockets are usually directed towards the flow, while the slopes must be kept as precisely as possible.

Replacement of sewage pipes should be done with special attention to the supports and fastening of PVC pipes. On open pipes should be supported as often as possible, for example, on horizontal - through 40 centimeters, and on vertical - through 100 (they are usually placed under the base of the bell). A prerequisite is the use of plastic or rubber gaskets between the pipe and the metal yokes of the supports. Replacement of the sewage riser also requires special attention, as well as compliance with established norms and rules that do not allow the entire structure to deform due to temperature differences.

In places where pipes penetrate various building structures, they need to be wrapped in two or three layers of tulle or parchment, and the entire depth of the hole should be cemented. After finishing works, you can install plumbing equipment.

Now you know how the sewage system is being replaced.
