Currently, the cartridge for the mixer allows you to control the pressure and temperature of water in products with one lever. The ceramic device includes two washers tightly pressed against each other. They undergo special processing using ultrasound. Thanks to this, it is possible to achieve a clear interaction between the plates at the molecular level, so even a drop does not leak between them. For hoses, flexible hoses for mixers braided with metal thread are often used. Such products are very often used for water supply of plumbing and heating equipment.
You can also often see a cartridge for a
ball mixer, which got its current name due to the regulating head serving as the main structural element. It is made of stainless steel in the form of a hollow ball with a pin and certain holes. It is held tightly in the case. Cold and
hot water is delivered through pipes to
it. Inside, there is a mixing of liquids of different temperatures. When the ball is rotated using the handle, the size of the holes that control the amount of water in one direction or another changes. Therefore, already warm water flows from the tap.
Sometimes a device fails, but you should not rush to get a new product right away, since you can only replace the cartridge for the mixer. Before starting work, shut off the water supply. On the front of the product should be a decorative plug, which must be opened with a screwdriver or knife, then unscrew the locking screw. As a rule, this is done using a hexagon. Further, the crane lever is removed from the housing. Underneath it is a cartridge pressed by a wide nut. Without removing the lever, the replaceable element cannot be reached. When installing a new element, it is necessary to check the correct alignment of the holes.
Each cartridge for the mixer, although it is a collapsible design, cannot be repaired: it is very problematic to purchase individual elements. The main failure is that there is wear on the moving parts inside. As a result, ceramic inserts can no longer provide a snug fit, water penetrates outward, even if the tap is closed. In some cases, even ceramic plates wear out. It is also very common to leak due to ingress of specks between the disks.
Nowadays, electronic faucets equipped with a flow limiter and a burn protection system are increasingly entering the market. Budget models can not boast of additional features. It is not easy for an inexperienced consumer to design a fake by design, as plagiarists have learned to copy a form very well. However, attention should primarily be paid to the quality of the coating: fake products have nicks and burrs on the edges. It is also recommended to immediately check the tightness, which to some extent is the key to quality.
