It is possible to change the direction of the pipeline by means of metal or plastic sewer branches. Release branches under corners in 30, 45 and 90 degrees which are also used for reduction of pipes of any diameter.
Types of sewer branches
Now it is impossible to meet metal branches. Producers have completely passed to parts from polyvinylchloride. They differ in smooth internal walls thanks to what drains well pass. Besides, they are resistant to high temperatures. In toilet bowl or sink it is possible to pour out quietly even boiled water without negative consequences for pipes.
Branches for the sewerage become under normal corner or with reduction. The first are public, they are issued any producers and are on sale in shops of the sanitary equipment. Nevertheless, there can be need for pipe under specific corner, it is necessary to collect suitable fitting independently. Such need can arise if pipes are established in owner-occupied dwelling: there when laying pipes any turns which depend on conditions of relief, arrangement of constructions and landscape are possible.
Having collected several fitting, it is possible to change turning angle. If to connect together two branches on 30 degrees, withdrawal of 60 degrees will turn out. It is possible to think out various combinations, achieving the necessary result.
It is easy to connect together two fitting, not only experts can make it. Branches do with bells on one end thanks to what it is easy to bring together them by the hands, without use of additional equipment. At the same time it is necessary to use sealant for sealing. For example, rubber two-lobe ring which provides dense accession.
Life cycle of correctly collected design makes more than 50 years without major repair. The main thing is to carry out scheduled maintenance and in time to clean pipes.
The second type – more difficult. These are adapters with reduction. They are used in household, on production, in other buildings with water supply system. In such houses the sewerage system which cannot do without normal and difficult branches is equipped. Sometimes it is required to change pipe diameter also.
In this case fitting with various turns is used: 30.45, 90 degrees. At the same time there is reduction on 50 mm. It can be located at the left, on the right, in front or behind. There are branches with reduction from several parties. Therefore it is possible to pick up suitable option.
Besides, branches on 50 mm at an angle in 45 degrees are issued. They look as short pipes 110 mm long with fitting from one or both parties. If there is need for turn on the main 110-millimeter pipe, it is necessary to cut in it necessary corner of the corresponding diameter.
By means of fitting it is possible to collect complex sewerage system with set of turns and various diameter of pipelines.
Branches in the form of T-couplers and crosspieces
Some sewerage systems differ in the increased complexity. To connect in uniform network of pipe in such configuration special branches in the form of T-couplers are used. They can settle down at the left, on the right or behind and also from two or three parties at the same time.
To find suitable 100-millimeter T-couplers with branches in 50 mm and at an angle in 45 degrees simply. If necessary corners under turn by the necessary degree crash and of 500 mm though it is a little complicates mounting.
Fitting bottles
Branches in the form of bottles it is used when there is need to change pipe diameter, but to keep corner, that is to correct it in a straight line. In shops of plumbing such fitting is on sale under the name "sewer semi-branch". On the one side of its diameter makes 100 mm. It is built in by this party pipe socket with a diameter of 110 mm. Branch since other end makes 50 mm. Thus, fitting bottles is necessary for reception of drains from sink or shower, but not branch.
To mount such systems not easy. Special difficulties arise at correction of system under the washing machine automatic machine. Polyvinylchloride branches for the internal sewerage with diameter of 32 mm are not issued. Instead of them branches on 50 mm in which 32-millimeter pipes are mounted are used. At the same time the rubber reduction is used. The same system is provided for corrugated pipe in 400 mm.
Mounting of sewer branches
Mounting of complex sewerage systems raises many questions at nonprofessionals. First of all it is important to remember that any drain (except for the washing machine automatic machine in which water supply is carried out in the compulsory way) has to have strictly certain bias. For example, pipelines with a diameter of 50 mm do under bias 2.5-3.5 cm by 1 running meter, with a diameter of 100 mm – 1.2-2.0 cm by 1 running meter, with a diameter of 150 mm – 0.7-1.0 cm by 1 running meter, and for 200 mm – 0.5-0.8 mm by 1 running meter.
To provide full sealing of the pipeline, it is necessary to condense all joints at pipes and fitting by means of special rubber two-lobe rings. When pipes and fitting are released by different producers, joining is at a loss. It will be difficult to insert fragment into bell, besides the consolidation ring can zalomatsya. To facilitate process, apply on ring liquid means for washing of ware. Thus sliding will be created, and it will become much simpler to assemble the pipeline.
For durability the sewer pipeline should be fixed by special brackets from plastic or metal. In some, exceptional cases if the pipe is closed by finishing, it is fixed, driving into the corner steel perforated tape suspension which is intended for plasterboard designs.
If the pipeline lies in places where will be exposed to low temperature impact, it needs to be warmed. For this purpose approach polyfoam, expanded polystyrene, mineral wool, penopolietilen.
For the correct creation of sewerage system in the house or at the dacha it is important to carry out correct calculations initially. It will help to buy suitable branches with the necessary angle of turning and necessary diameter at once.
