Connecting plumbing in the bathroom (washbasin and bath) to sewage is not difficult. But that these devices work correctly, it is necessary to take into account several common important points.
Connecting the sink drain pipes and baths to sewage must be performed with the device of the corresponding hydraulic assets.

That is, both for the sink, and for this purpose, you should connect devices for this purpose, which, creating inside a water plug, will prevent the appearance of unpleasant smell from the sewage. Such devices are called siphons. Currently, siphones for plumbing The existing market offers a great set. But, as a rule, siphons made of plastic are most in demand. They are inexpensive and durable. Also, arranging the connection of water drain pipes to sewer for the sink and bathroom, many face the specific features of these connections, the specificity of which is that the main thing is that the sink is correctly selecting the siphon, given its configuration and sizes, as well as the possible need to connect through it Siphon draining water from a washing machine. Connecting a bathtub to sewage is carried out using appropriate devices, taking into account its location and existing sewer pipes.

The connection of the sinks of the sink to sewer is simply carried out: through a rubber coupling 50/40, in the case of plastic sewage pipes by 50 mm or via the 73/40 transition clutch - in the case of cast-iron sewer pipes. The size of 40 mm is indicated because it is such a diameter, as a rule, a drain pipe has a drain pipe in siphones. To connect the drain reinforcement to sewage, when the diameter of the tube is 40 mm, the sealing gasket is used, which is worn on the tube. The same gasket can be used if the diameter of the input pipe is 50 mm, and the transition tube 40/50 is used in the drain. To facilitate the organization of the joint of the specified pipes, the applied sealing gasket is recommended to be deceived from above soap or gel for washing dishes.

The situation is somewhat different when the bath is connected.
How to connect a bath for sewage?
After the bath has been purchased and delivered to the bathroom room intended for it, it must be properly installed, taking into account the configuration of the room, existing pipes, engineering communications and design solutions.

Deciding with its overall location, which will subsequently be due to the connection of water and sewage pipes, it is necessary to adjust its stability, height and tilt.
Baths can be installed on legs, stands or other supports. At the same time, they must withstand the mechanical load of at least 100 kg applied to the long side of the bath anywhere vertically down, and be stable.
In addition, at least 145 mm from the floor from the floor to the outlet of the bowl in the height of the bath. This is done so that you can create a necessary height difference in the zone between the drain hole and the dial of connecting to the sewage. If the height drop will not or it is insufficient, water from the bowl will be bad and may be stamped. In addition, the obtained space between the floor and the bottom of the bowl will allow you to organize relatively free access to the plum for a possible revision or replacement of the siphon.
After installing the bath on the above supports or stands, they make test measurements of the heights obtained: a) from clean floor to release, b) from pure floor to top of the bowl of the bowl at four points at its corners. The latest data should not differ from each other more than 4 mm.
Next, the bias of the bath bottom in the direction of the outlet through which the bathing is connected to the sewage. This bias is set at the rate of 2 cm per 1 m tub.
After the work is completed on its installation and adjustment and the cup is finally fixed by vertical and horizontally, you can start connecting it drain to sewage.

Selecting a siphon for connecting a drain bath to sewage
Siphon scheme.
The bath connection to the sewage pipe is recommended using the corresponding siphon - special fittings, which has an in its composition nodes that connect to the drain hole and overflow hole (photo 1).
When choosing a siphon, it is recommended not to acquire models with corrugated plum tubes, as they have the following significant disadvantages:
- possess large hydraulic resistance;
- quickly clogged with mud;
- poorly cleaned.
The best choice will be a drain device, constructively consisting of a rigid or flexible, but smooth plastic pipe. If the configuration of existing sewer pipes allows you to apply a drainage device consisting of two rigid pipes, with the required turns, it will be the best solution.
But if the situation does not allow to apply none of the recommended options, then it remains to use the design of corrugated plastic pipes.
Assembly and connecting the drain bath to sewage
Assembly and installation of the siphon.
Siphon mounting scheme.
When the drain device is purchased in accordance with the recommendations on the selection, it is possible to start it. Collecting and installing the device according to the instructions attached to it, some order should be observed. First, it is assembled into one whole system of the hydraulic assembly consisting of parts of the drain and overflow, since it goes in the form of individual fragments. At the same time, it is necessary to pay attention to the availability, quality and condition of the gaskets, as well as fixative nuts of the system.
When installing the nut, the nuts should be passed carefully and without skew and tighten with hands without applying the tool force so as not to damage the material of the design and do not thread the thread when tightening. On the bath is mounted overflow by fixing it in the holes of the bowl using the decorative lining and the screw. After that, the plastic tube is fixed on overflow, the free end of which will be attached to the appropriate drain dive.

Next, in the case of the bowl, there is a sealing ring on a drain hole, a metal drain neck is installed on top of it. From the bottom to the neck, the assembled drain is supplied and connected by the fastening screw. The next step is to dock overflow and drain by means of a plastic tube from overflow, which joins and attached to the plum. When performing these works, you should pay attention to how each sealing gasket is located on the holes of the drain and overflow of the bowl. In addition, it is necessary to carefully check the correctness of all compounds performed in order to avoid possible leaks.

After plumbing plumbers mounted and checked, it can be connected to the sewer network by cutting with a rigid or flexible smooth plastic tube (if it is impossible to perform such a compound, the corrugation is used). If the sewage system is arranged using pig-iron pipes, then a transitional rubber clutch 73/40 should be applied to the dusting with it and seal the plum input.
If in the building the sewage is made by plastic pipes with a diameter of 50 mm, the discharge of a drain is recommended via a transitional rubber clutch 50/40 or using the corresponding adapter from 40 by 50 mm. In the latter case, to seal the joint on the drain pipe introduced into the sewer, it is recommended to wear a 1,5 mm thick sealing gasket so that the upper part of the input is additionally embedded with a water-resistant sealant. Similarly, it is recommended to perform a plum input if the diameter of the sewage pipe is 40 mm.
In order to ensure normal operation of the mounted drain and overflow of the bowl, you need to fill it with water to the level of overflow and, merging the water, check all loaded connections on the leakage. If the siphon connections remain dry, then it can be concluded that the work is done well.
