Mixers with replaceable cartridges today have become a permanent attribute of the kitchen. The cartridge must be properly selected and installed, providing for its subsequent replacement. Natural wit, human curiosity and stinginess make compatriots dismantle replacement cartridges in order to replace the element. The fact that in European countries is subject to a fundamental replacement or simply a release, by the hands of our artisans acquires a second life.

Mixer element
The main functional element of the mixer is a replaceable cartridge that mixes water and regulates the intensity of its supply.
Daily loads from water and pressure in the water system affect the state of the cartridge, the mixer starts leaking and digging. Replace the cartridge should be made according to the installed model and the recommendations of the manufacturer of plumbing fixtures.
The basis for choosing a cartridge are:
• valve manufacturing material
• Typical body diameter (from 35 to 40 mm)
• the length of the working rod and the configuration feature of the seat.
Replaceable cartridges are distinguished by their performance. Types of cartridges for mixers: ball or plate, which in turn are divided into demountable and non-separable models.
Helpful Tips
The principle of operation of ball and plate (disk) cartridges is identical. The difference lies in the design: the ball cartridge in the base of the device has a ball with holes for the flow of water, and the plate-type ceramic discs.
Closure of the water flow near the ceramic plate cartridges is carried out due to the tight connection of the protrusions of the holes of the plates. Naturally, the difference in price: cartridges made of cermets with a brass stem are cheaper than a cartridge thermoregulator.
Units cartridges, unlike the dismountable model, are not subject to repair. They are completely replaced by a knot.
Mixer Cartridge Assembly
The demountable design of the cartridge for the single-lever mixer consists of the elements:
• plastic housing
• the bottom cover
• two ceramic plates
• the stem
• silicone gaskets.
The density of the assembly of two polished mobile ceramic plates and the mechanical forces are calculated for a certain work cycle. Cartridge for single lever mixer Grohe is designed for 200 thousand cycles of work, and the cartridge Sedal for 150 thousand cycles.
The long operating life of disk ceramic cartridges and the exact degree of interfacing of the elements are achieved by grinding the plates on ultrasonic devices.
Choose a cartridge for the mixer, how to do it correctly
Select the used element will have after disassembling the design, because the mixer is supposed to use a native cartridge. This is due to the technical parameters and the possibility of design.
For example, a cartridge for a 35 mm mixer on a SEDAL leg will sit at a height of 4 mm at a center-to-center distance of 24 mm with a housing height of 42 mm and a stem of 65 mm. No more, no less! Models of the cartridge on the legs (orientation peg) require special attention. Therefore, to select a cartridge for the forthcoming replacement, just take an old cartridge with you.
Select the cartridge is also recommended for the following parameters:
• the presence or absence of an ISO 9001: 2000 certificate, confirming the quality and manufacturability of production for assembly units of products of enterprises
• An act or a guarantee that this batch of cartridges has been tested at a working pressure of 3.5 atm, which the cartridge is capable of withstanding.
If these documents are not available, then before you an ordinary "Chinese", no one will be responsible for a substandard product.
In the meantime, to dismantle the old product, you should perform such actions.
Replacing the cartridge in the mixer, step by step
Mounted on a sink or wall mixer, attached to water pipes, when replacing the cartridge does not need to be dismantled. It is better not to touch it at all.
Replacement of the cartridge begins with the overlapping of cold and hot water supply.
After making sure that there is no water supply, remove the plug of the mixer handle (checkbox). Under the plug is a screw M5x6, which fastens the handle to the rod. The screw must be loosened using a screwdriver or a hex wrench. Then we release the protective cover 48x42x1 / 19 "in the form of a nickelated hemisphere.
Under the casing is located the regulator nut 42x1 / 19 ", which should be unscrewed to gain access to the cartridge. The cartridge is easily removed from the mixer socket.
Theoretically, dismantling looks beautiful and simple. But in practice, you will have to face the immobility of the protective housing or mixer nuts, which should be treated with a liquid WD-40.
Experts recommend not to exert considerable effort in dismantling the cartridge, using a special agent to dissolve the salts of the calcareous plaque.
Remove the cartridge from the mixer if necessary, you can disassemble it.
disassemble the cartridge
To disassemble the cartridge, use a long screwdriver, with which the body is separated from the lid by snapping the case near the latches. Then remove rubber or silicone gaskets, and the mechanism leaves freely from the housing.
The mechanism consists of two plates, one of which (with a hole) is fixedly fixed to the rod, and the second one can be moved in the plane of the first. The plate is freely separated from each other.
A quality cartridge serves a long time, so when selecting it is necessary to clarify what material the valve is made from.
Thus, the conclusion suggests that replacement of the replacement cartridge in any modification of the mixer can be done by hand, it is sufficient to select the correct element.
