Toilet sink: how to pick up and repair the most important
None of the sanitary appliances in the toilet can function without water, which accumulates in a special container, and after activating the drain fittings, it enters the bowl, where it washes away biological waste. Comfort and hygiene in the restroom depends on how efficiently this happens. In order to choose the optimal model with your own hands, you need to know what toilet bowls are by the type of drain and the location of the outlet.
Let us dwell on this in more detail.

Toilet Selection
According to the location of the drain pipe
As you know, sewage in the bowl of sanitary equipment, washed with water coming from the tank, then get into the sewage system. And on how the toilet pipe is located for the toilet bowl, you must select the appropriate device.
There are three varieties:
- Horizontal drain - These models are suitable for installation in latrines, where sewage pipes are located along the walls (or embedded in them). At the same time, the neck of the sewer system itself should be located at a height of 10-15 cm from the floor surface.
If during installation it is found that the diameter of the toilet bowl and the pipe dimensions (or their placement relative to each other) do not coincide a bit, eccentric cuffs of different diameters can be used for docking.

- Floor drain - the toilet of such a system has a vertical location of the pipe. For obvious reasons, the sewage system should be located in the floor (floor). In this case, installation is greatly facilitated: it is enough to install a special sealant, then insert the nozzle into the hole intended for this and fix the device on the floor.
Note! A toilet with a sink in the floor can be installed not only on any of the walls, but also anywhere in the toilet room (even in the middle). It is only necessary when installing the waste disposal system to take care of the presence of a drain mouth there.

- Oblique plums. The drain pipe for the toilet, as the name implies, is angled. This is the most versatile system that can be used regardless of the characteristics of sewer pipes.
The instructions for connecting the described sanitary device with the drain system include the use of special cuffs or flexible corrugated pipes. Their price is low, but they make it possible to make a tight and reliable joint even in the most difficult conditions.

By type of drain fittings
As you know, there are several ways to locate the drain tank. It can be an integral part of the toilet, mounted on a special shelf in the back, installed hidden in a wall or hung over the toilet.
Note! Suspended tanks, although they can get rid of sewage most effectively due to the strong flow of water, have a significant drawback: the loud sound of the toilet bowl drain. Therefore, installing such a system, you should weigh the pros and cons of the solution several times.
But the most careful should not select the tank itself or its location, but the devices that provide the drain: for the toilet bowl there are 3 of the most common types of valves:
- Bell. An obsolete system, which is gradually being discarded, replacing it with more economical and simple mechanisms. Externally, it is a lever, one end of which goes out and serves to initiate the descent of water, and the other is connected to a cast-iron bell that covers the outlet.

Tightness is ensured by a special rubber gasket, which must be replaced from time to time.
The disadvantages of such a system include its cumbersomeness, as well as the need to clean the surface of cast iron from rust and mineral deposits every few years. The advantages - a very long service life.
- Corrugated. The scheme of work of the drain fittings is similar to the previous one, but here a plastic corrugation is attached to the second end of the lever, which regulates both the flush of water into the toilet bowl and the subsequent filling of the container.
The main problem in this case is frequent wear of the plastic part. Although the process of replacing it is simple, not every home artist is ready to perform this operation every 12-18 months.

- Pear. The modern scheme of management of water discharge, which in one or another modification is used in the overwhelming majority of tanks.
The principle of operation is simple: the hole through which the liquid from the tank enters the bowl of the toilet bowl is closed with a rubber bulb. To bring the mechanism into action you need to raise it using a lever or a button.
Tip! The use of fittings with a pear allows you to decide how to reduce the drainage of water in the toilet. No need to reinvent the wheel. It is enough to buy a model equipped with two buttons, by clicking on which you can drain either all the accumulated water, or only a part of its volume.

Despite all the advantages, there are disadvantages:
- A rubber bulb (or a pad on it) after several years of operation loses its qualities and does not form a tight joint. Exit - replacement of worn parts.
- The plummer hole sealant with which the pear touches can also become clogged, resulting in water leaks. A simple cleaning or replacement of the gasket will help solve the problem.
Solving problems with the discharge of water
Many novice home craftsmen wonder why water in the toilet does not drain well. The reasons for this may be many. In this case, the problem does not always lie in your plumbing fixture, possibly a fault in the sewer pipe. Therefore, below we will focus not only on the methods of troubleshooting, but also on the rules for their diagnosis.
Tip! The resulting trouble must be addressed as quickly as possible, not postponing. Especially if you have a washing machine in the toilet. A powerful stream of water coming from the hose during the spin cycle can cause a flood that will cause trouble not only for you, but also for the neighbors below.

There are two most common problems associated with the discharge of water:
- the liquid slowly goes to the drain;
- the flow from the tank is too weak and cannot remove the waste in the bowl.
Consider how to repair the toilet sink in either case:
- A bad drainage from the bowl of the sanitary device is hampered by the resulting blockage. Before undertaking elimination, it is necessary to localize the place of its formation.
To do this, you need to check the quality of the work of the sinks in other places: sink, bathroom and so on. If the water goes slowly and there, the blockage is in the sewer pipe and you need to invite a plumber or use a special cable to eliminate it.
When the water in the kitchen or bathroom is drained quickly, and the toilet does not want to work, with high probability we can say that the problem was formed in the toilet drain pipe.

Get rid of the cork is easy. To do this, you can use soda with vinegar. Drain the liquid from the bowl, pour half a pack of soda inside, and then gently pour it all with a glass of vinegar. After the reaction, flush the waste with a bucket of hot water.
Another effective option - plunger. Everyone can use it. Attach the rubber part to the plum and make several intense movements with the handle up and down. This will help break the cork out of the trash.

- The reasons for the slow discharge of water from the tank most often are problems with drain fittings or drain holes blocked by mineral deposits under the rim.
In the first case it is necessary to replace the spoiled gaskets. Their wide range is presented in hardware stores. During the purchase, do not forget to make sure that they fit your device specifically in size.

Tip! If you do not want to bother with the replacement of individual parts, buy and change the drain valve as a whole. Its cost is low, but you will save a huge amount of time and nerve cells.
In the second case, you will have to wash the bezel. For this purpose, special potent compounds are used. During the procedure, do not be lazy to take care of your own safety by protecting the skin and respiratory organs and eyes.
