Drain for the toilet most often comes with a bowl, despite this, you should be careful when choosing it. Familiarization with the features of installation, the principle of operation, possible malfunctions and ways to eliminate them will save time and the family budget.
Varieties
This device is sold in two versions: dual-mode and single-mode. The latter is equipped with two buttons, each of which is responsible for supplying a certain amount of liquid. Its main advantage lies in saving water resources by using the full volume only when necessary.
Single-mode toilet flush dispenses all the water from the tank at the touch of a button.
Both versions have the same principle of operation, only the method of transferring movement to the valve device differs, the functioning of which depends on the design. The valve can be mounted on tubular stems used for overflow. Also, the opening and closing of the device is possible with the help of metal orplastic chains. But this technique is characterized by frequent breakdowns.
Buttons
There are two types of buttons: some open the valve with plastic levers, others have an independent mount. The toilet flush mechanism is also divided into two types:
- Top has gained the most distribution for built-in cisterns or located at the bottom. Using the head or buttons, actuated automatically or manually, the operation of the device is carried out.
- Side is convenient for containers that are high in relation to the bowl. In this case, it is equipped with a special chain. The button is used when placed low.
What you need to know
For proper repair work, you need to know about the features of the device and structural elements. The toilet bowl consists of two main parts - a tank with water and a bowl. Under the lid of the tank is a toilet drain. It includes seals, levers and a float. The principle of operation is to collect water and then drain after pressing the button. The float provides adjustment of the degree of water intake. Depending on the brand and manufacturer, the structural elements may differ, but the principle remains the same.
The operation of the drain is affected by the functioning of its subsystems: drain and typesetting. The fittings for the toilet bowl are available in two versions:
- The bottom feed system is quite popular due to its almost silent operation.
- Reinforcement with sidefeed is fixed at the top. It is found mainly in economy class models due to the low cost of the mechanism, which makes a noticeable noise when used. Today, more and more often, it is supplemented with a special tube to supply liquid to the lower part and reduce noise.
Button functionality
Modern models are completed with a lever and a button. If the design of the tank involves a hidden installation, the button is mounted on the wall. Such toilets have not only advantages, but also disadvantages, the main of which is the difficulty of carrying out repair work due to limited access to fittings. As mentioned above, dual-mode systems are equipped with two buttons, but it is worth noting the increasing popularity of supplementing with a special key, the intensity of pressing which ensures the degree of water draining.
Installation method
There are several methods for installing the tank, each of which is suitable for certain conditions and has its own characteristics.
Fixed on a stand or the toilet itself is the most common. Rubber grommets are used to prevent leaks and improve the quality of fastening.
Mounting above the bowl is aesthetically inferior to other options, but at the same time it provides free access to internal elements in case of need for repairs. Also worth noting is the high efficiency of the drain, thanks to the natural force of attraction.
Installation in the wallrational when carrying out major repairs in the sanitary room. A special niche is made for the tank, which is subsequently closed with finishing materials, and the toilet flush button is brought to the surface. The main advantage is space saving, which is especially important in a small room.
Due to the fact that spare parts are quite in demand, finding suitable ones is not difficult. To eliminate breakdowns, in most cases, fittings for the toilet cistern, components or assemblies are replaced. These include flexible hoses, buttons, overflow, valves, as well as the tank itself, since this ceramic element is quite fragile and easily damaged by impact or any other mechanical impact.
Some problems can be solved by using special sealants, epoxy glue and other compounds. But they only delay the replacement of the node for a while.
Toilet flush: how to choose
The structural elements of the top drain can be made from different types of materials. Brass and bronze parts are the most durable, strong and resistant to harsh chemicals.
Care must be taken in choosing parts such as the toilet drain pipe, fittings and shut-off valve, as low-quality products can lead to leakage. Valve devices must respond quickly and function without sudden jerks. If jamming is noted, then such a part should be put aside.
Classicthe version of the tank has a separate mechanism for filling and draining. This greatly simplifies repairs and makes it possible to replace only one part if the other is not damaged.
If you encounter difficulties with an independent choice, you can come to the store with a damaged item and ask the consultant to pick up a high-quality analogue.
Types of issue
The oblique toilet flush is rarely used today due to the specific installation that requires fixing at an angle of 45 degrees. But the purchase of other options becomes impossible if the pipeline does not match the level of the tank.
Vertical outlet is used when sewerage passes through the floor, that is, under the floor of the room. It is gaining popularity due to its ease of installation and good drainage.
The most common is the horizontal release. This is due to the place where sewer pipes are laid in most Russian apartments. This option is installed when placing the system in the wall structure of the bathroom.
