The drain for the toilet most often comes complete with a bowl, despite this, it is worthwhile to be careful when choosing it. Familiarization with the installation features, the principle of operation, possible malfunctions and methods for their elimination will save time and a family budget.
Varieties
This device is implemented in two versions: dual-mode and single-mode. The latter is equipped with two buttons, each of which is responsible for supplying a certain volume of liquid. Its main advantage is the saving of water resources through the use of the full volume only when the need arises for this.
A single-mode flush for the toilet when the button is pressed gives out all the water from the tank.
Both options have a single principle of operation, only the method of transmitting movement to the valve device differs, the functioning of which depends on the design. The valve can be mounted on tubular rods used to provide overflow. Opening and closing the device is also possible with the help of metal or plastic chains. But such a technique is characterized by frequent breakdowns.
Buttons
There are two types of buttons: some open the valve with plastic levers, others have independent mounting. The toilet flush mechanism is also divided into two types:
- The upper one has gained the greatest distribution for built-in tanks or located in the lower part. Using the head or buttons, driven by an automatic or manual method, the device is operated.
- Side is convenient for containers with a high location relative to the bowl. In this case, it is equipped with a special chain. The button is used for low placement.
What you need to know
For proper repair work, you need to know about the features of the device and structural elements. The toilet consists of two main parts - a water tank and a bowl. A toilet drain is hidden under the lid of the tank. It includes seals, levers and a float. The principle of operation is to collect water and then drain after pressing a button. The float provides adjustment of the degree of water intake. Structural elements may vary depending on the brand and manufacturer, but the principle remains the same.
The operation of its subsystems affects the operation of a drain: drain and typesetting. Fittings for the toilet bowl are available in two versions:
- The system with a lower feed is quite popular due to the almost silent operation.
- Side feed fittings are 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, it is increasingly supplemented by a special tube to supply fluid to the lower part and reduce noise.
Button Functionality
Modern models are equipped 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 complexity of the repair work due to the limited access to fittings. As mentioned above, dual-mode systems are equipped with two buttons, but it is worth noting the increasing popularity of the addition of a special key, the intensity of pressing which provides the degree of water drainage.
Installation method
There are several methods for installing the tank, each of which is suitable for certain conditions and has its own characteristics.
Fixing to a stand or the toilet itself is the most common. Rubber gaskets are used to prevent leaks and improve the quality of fastening.
Mounting above the bowl in aesthetic terms loses to other options, but at the same time it provides free access to the internal elements in case of need for repair. It is also worth noting the high efficiency of the drain, due to the natural force of attraction.
Installation in the wall is rational when carrying out major repairs in the sanitary room. A special niche is made for the tank, which is subsequently covered with finishing materials, and the drain button for the toilet is brought to the surface. The main advantage is space saving, which is especially true in a small room.
Due to the fact that spare parts are quite in demand, the search for suitable ones is not difficult. To eliminate breakdowns, in most cases, fittings for the toilet tank, accessories or components are replaced. These include flexible hoses, buttons, overflow, valves, as well as the tank itself, since this ceramic element is quite fragile and is easily damaged by impact or any other mechanical impact.
Some problems can be solved by using special sealants, epoxy adhesives and other compounds. But they only temporarily delay the replacement of the assembly.
Toilet drain: how to choose
Structural elements of the upper drain can be made from materials of various kinds. Brass and bronze parts are characterized by the greatest durability, strength and resistance to aggressive chemicals.
Care should be taken when choosing parts such as a toilet drain pipe, fittings and a shut-off valve, as low-quality products can cause leakage. Valve devices must operate quickly and function without sudden jerks. If jamming is noted, then such a detail should be put aside.
The classic version of the tank has a separate mechanism for filling and draining. Thanks to this, repair is greatly simplified and it becomes possible to replace only one part if the other is not damaged.
If you have any difficulties with an independent choice, you can come to the store with a damaged element and ask the consultant to choose a high-quality analogue.
Types of release
Oblique flushing of the toilet is rarely used today due to the specific installation, requiring fixing at an angle of 45 degrees. But the acquisition of other options becomes impossible if the pipeline does not match the tank level.
The vertical outlet is used when passing the sewage system in the floor, that is, under the floor of the room. It is becoming more widespread due to the ease of installation and ensuring high-quality drain.
The most common is the release of a horizontal view. This is due to the location of the sewer pipes in most Russian apartments. This option is installed when the system is placed in the wall structure of the bathroom.
