How do I change the cartridge in the faucet: the replacement of a mixer in the kitchen

When the output of the mixer down is not necessary to go in search of the new. One need only change in the faucet cartridge. Especially because the cost of this small detail is several times less than the price of a new mixer.

The operating principle of a single-lever mixer

In contrast to designs equipped with two valves (for hot and cold water) single-lever mixers have one single handle, with which the continuously adjustable not only temperature but also the power head. Such devices are often called ball, hinged or joysticks.

Mixing water in such devices is performed using cartridges or ball arrangements:

  • ceramic disc cartridges. It consists of several perfectly polished ceramic discs with three holes; one for cold, hot water for the second, and the third for the final output stream; liquid mixing is performed in the upper compartment; when turning the crane wheels shift lever, wherein the holes may be partially or fully coincide; for adjusting the pressure value on a special plate;

  • ball mixer: its interior are thoroughly polished form hollow sphere with three openings; via ball lever is displaced, wherein there is an overlapping of openings whereby water flow adjustment is made and its output power;
Internals ball cartridge

In case of failure of ball repair devices are usually not subject to. Plus, because of the mix inside the ball, he quickly becomes clogged with scale, which is the most common cause of failure. In these devices wear out quickly and the rubber gaskets, seals. Replace the disc cartridge in the faucet in the kitchen or in the bathroom is not too much trouble.

The reasons for the failure of the cartridge

Primarily for this equipment wear process is substantially affected by impurities contained in water - sand, rust, as well as dissolved salts. When they enter the friction between the disks is much more intense, ceramics gradually abraded and the ink cartridge begins to flow.

When the cartridge is clogged with rust and lime salts also can decrease the temperature and water pressure. In this case, it is sufficient cleaning. Cheap Chinese mixers often have a small inlet, and no cleaning will not help here. It helps a replacement device at a higher quality.

Low water pressure may occur when driving crane mesh filter. In this case to correct the problem is enough to remove the grid at the end of the goose and her well cleaned. Poor water flow possible during pile and water pipes. You can check this by turning off the valves of her feeding and removing the mixer, and then again slightly open them. If water enters the pipe without any problem, the problem in the mixer.

To increase the pressure only sometimes required to clean the strainer

The reason for the weak head can be covered and damaged rubber seal. Shifted from the place it is able to block the flow of water. tap noise may appear at sharp pressure drop. To eliminate it is sufficient to replace the gasket.

When purchasing poor quality tap or long-term use of the product due to cracking or offset disc cartridges are often jammed. In this case, the tap handle starts to move in spurts, or ceases to move. In this case, the repair of the cartridge can not be - it will have to change. Because of this defect is also possible water leakage from the mixer lever.

Tip! Clean and lubricate succeed only folding cartridge. If this detail is not folding, only one way out - to be replaced.

Recommendations regarding the selection of the new cartridge

Products even one manufacturer, designed for different models of mixers, may be small, do not throw directly into the eyes of the differences. Even if the wrong size cartridge you can still insert a crane will squeak, buzz, and the handle is bad turn. Yes, and will last a short time the product. Therefore, when buying necessarily specify all the parameters.

In specialty stores sellers are generally familiar with its product range and its ability to find the right product to you. For ease of comparison, the old cartridge is better to take with you. Search same cartridge for cheap Chinese mixer can be difficult. Standard cartridges to them may not be appropriate.

  2. The same must also all the grooves and ridges. Otherwise, fix the item is simply impossible;
    Form of holes in the ceramic disks and their size can vary greatly
  3. If these parameters are the same, measure the diameter of the cartridge, as well as its height with the stem (stalk) and without it. Standard diameters of 28, 32, 35 and the largest 40 mm;
  4. Should pay attention to the length or width of the rod - for certain types of mixers, this parameter can be critical.
The dimensions of the cartridge from the same manufacturer and the form may be different

  4. Some people believe that when you install the filter slows down the water pressure. However, high-quality products fine filter is not able to influence the level of pressure. When blockages is enough to open the gate, and he will take the garbage down the drain;
  5. Although modern faucets already equipped with a filtration system, additional barrier arrangement for collecting large inclusions not hurt. At the entrance to the apartment set just to be coarse filters. After all, the main cause of sanitary equipment failure is the quality of tap water.
