In each bathroom there must be a mixer, through which hot and cold water is supplied with a certain pressure. There are a variety of types of mixers, which have their own characteristic differences. A few decades ago there was only one type of faucets that was mounted in the bathroom. It was a universal design, which simultaneously came to the washbasin and the bathroom.
Types and devices of mixers.
The device had a long spout that could rotate 180 ° C. Everyone knows this construction. The flow of water occurs through pipes fixed to the wall. At that time, fixing the mixer in some other place was considered impossible. I must say that the bath was also not very attractive.
Today, the modern bathtub has evolved into a design made from several different materials, in a variety of shapes and colors. For modern design developments, other technological approaches are needed, it concerns the supply and regulation of the pressure of water. This made it possible to install the mixer today in accordance with the existing design of the bathroom.
The material can be:
Drawing of a brass mixer.
The best is considered a brass mixer. This design never corrodes, is characterized by high strength, long operation.
The surface of the mixer is chromium plated, then it is covered with enamel. The price of such a device depends on the anticorrosive coating. Usually it is quite accessible to an ordinary buyer.
The cheapest designs are made of plastic. However, this does not mean that the whole construction is made only from it. From plastic make shower heads and handles.
Silver and gold are used in luxury plumbing, the finishing of the bathroom is made of natural materials:
- expensive wood species.
The appearance of such a bath is always aesthetic, and all plumbing is very functional.
Variety of species
They are divided into categories, which are also divided into several parameters:
Location. Installation is done on the walls next to the plumbing devices. The fixing of the communications is hidden behind the lining, only the couplings that match the mixer are visible. This wall structure has a very rigid installation, it has good bandwidth. Installation can be made at any height.

The device is fixed on the side of the bathroom. It is distinguished by its high compactness, fashionable design and special fastening. Such bathtub faucets are often completing additions, when the installation of elite sanitary ware. In-store mixers sold in stores may not be suitable for conventional bathtubs, so they are not very popular.
Constructive differences. Tens of years in the bathroom installed models with two cranes. This is a standard design with two handles that regulate the simultaneous supply of cold and hot water. These devices have a very simple design, are distinguished by a low price, which varies depending on the material and brand of the manufacturer.
Such a mixer is easy to repair: it is enough to replace rubber seals and the problem of percolation will be solved. This type has a high throughput. This has a positive effect when low pressure is maintained in the water supply system.
Basically there are:
Tools for mounting the mixer.
- Mixers are ball. The principle of operation of such mixers for baths is similar to the two-valve, but the locking mechanism is a hinge having several holes. When they are combined, water begins to flow through the tap. A positive property of this design is considered high patency. The device is easy to adjust, has a simple design, can work for a long time without repair.
- Single-lever. This type of mixer is a modern design, characterized by originality. The water supply, its mixing is carried out by a single lever. It mechanically includes a mixing cassette located in the tap. The principle of operation is based on plates with small channels. When the plates are displaced, water flows are dosed and mixed. It is very easy to use such a device, the water supply is adjusted very quickly, it is enough to press the lever lightly. A negative side can be called a limited flow of water due to the small diameter of the through-holes. If the system pressure is very low, the water jet is greatly reduced.
- Thermoregulated. This type represents the latest engineering designs. The temperature is maintained automatically and set to a specific mode. It should be noted that the number of modifications of such mixers is increasing every day. These devices are very expensive. For their normal operation, a constant system pressure is required. In this regard, they found application only in the bathrooms, where an automatic system for feeding and adjusting the pressure of water is equipped.

Thermostatically controlled mixers can have:
- contactless adjustment;
Some models can run from a battery or a battery, and some are supplied with a generator that supplies current after passing a stream of water.
The original design decision is a mixer, which is fixed on a shelf. Basically, this is an ordinary decoration, which helps to create a non-standard solution when finishing the bath. Such delicacies make the project more expensive, sometimes even twice. Devices that are mounted on a shelf are very expensive. They are considered things related to the most elite design.
With this method, cascade mixers are often installed. This type is mounted in a niche, sometimes it is walled up next to the embedded bathroom. Sometimes podium is made or mounted on a special shelf, covered with ceramic tiles or natural stone.
There are a lot of options. You can install the mechanism everywhere. Using flexible piping, it became possible to mount a drain, shower and valves in the most suitable place. Therefore, the installation of a bath that has a non-standard shape, does not cause any special difficulties.
Sometimes a sliding installation is carried out. Builders consider this type of attachment not very reliable. This is due to the fact that the constant extension and removal of the hose leads to a rapid wear of the mechanism.
When the bath is joined to the wall, the rod can be fastened directly to the bath.

The result will be the ability to take a shower while standing.
There are also mixers, the fastening of which is made on the wall. They are equipped with a rotatable spout. Thanks to such a device, it became possible to simultaneously serve a washbasin and a bath. To take a shower, a shower was made. This type of mixer remains popular due to its high convenience. They help to fill the bath quickly, it's possible to stand under the shower.
So far, not many people can afford to have a shower in the house with a separate bathtub. A mixer equipped with a spout requires only one - the correct location of the bathtub. It must dock with the wall, in extreme cases should be located very close to it, everything else does not matter. In previous years, the device was mounted over the drain. In our time, the mixer can be installed in any place you like.
Of course, a lot of installation depends on the availability of pipe routing. It is necessary to take into account the existing distance between the pipes that were installed earlier. Mount the new mixer will only succeed on the already prepared old place. When major repairs are made, when it is planned to replace the pipes, it opens up the possibility of a little fantasy and fix the mixer according to the designer's idea.
When choosing a mixer that has a wall mount, it is required to determine the length of the spout, in other words, the distance from the wall to the "spout". Usually this value is prescribed in the attached technical data sheet. Manufacturers make mixers with several types of spills:
- a long;
The most fashionable are devices that have a short nose. However, if the "spout" is very short, the water will begin to fall on the side of the bathroom, and it will begin to flow past the bathroom. This nuance must be taken into account.

A good mixer is always provided with a detailed technical description. The attached drawings show the size from the wall to the middle of the jet. This must be taken into account, since reality sometimes does not coincide with the drawing data. For example, the rim does not correspond to the standard size, it is always different. The length of the spout depends on the width of the border. A large width means a long spout. Therefore, the most convenient mixer is one that is mounted on a wall equipped with a medium sized spout.
The wall-mounted mixer is equipped with a fixed stop so that the shower can be fixed. You can also install a shower rod, it will allow you to move the shower head vertically, rotate in the desired direction.
For each individual case, the concrete attachment height of the mixer is selected. The standard distance is 10 cm, receding from the rim. This amount is quite enough. In some cases, the mixer is fixed on the edge of the tile to lay pipes. If the mixer is mounted in an unusual place and fixed to the wall, the bath gets an original and spectacular look.
The design of this device has serious differences from standard mixers. There are no cranes, no lever, regulating the strength of the water flow and its temperature. This device is equipped with a special photocell. It includes the supply of water, controls the temperature and pressure. The mixer is switched on after the hand enters the field of view of the sensor.
Power is provided by ordinary batteries, there is the possibility of connecting to stationary electricity. Such an abundance of electronics affects the reliability of the device. The cost of such a product is very high, it is several times higher than the price of classic cranes.
But the sensory device has many positive qualities. Particularly distinguished is a high degree of hygiene. To turn on the tap does not need to touch the body, then on the body there will be no trace of microorganisms. This purity has caused the use of sensor mixers in common areas.
Scheme of the sensor mixer.
Any mixer, even a very high-quality one, if not properly operated, quickly fails. This is often associated with applying a lot of effort when you need to open or close the water supply. Affects the durability and quality of tap water. When the water is very stiff and consists of small particles, the entire structure quickly wears out. To reduce the effect of water, it is necessary to use special filters.
There are several ways to connect the pipes to the mixer. The most popular and often used are:
- copper pipes;
- flexible hoses;
- metal-plastic pipes;
- wall mounted faucets.
The device can be connected to water pipes using eccentrics. For this purpose, couplings are used. The thread at the connection points must correspond to the threads of the couplings.
This type of mixer is connected simultaneously to the pipe through which hot or cold water is supplied. The gap between the pipes should correspond to the location of the mixer, approximately 150 mm. The connection of the mixer to the water pipes is carried out through the eccentric nipples. They help to compensate for the discrepancy of such dimensions.
Connecting with flexible hoses. This type of connection is considered the simplest, it is very easy to do. To do this, connect the flexible hose to the pipe using a threaded connection.
When the flexible hose has an internal thread, when connecting it is desirable to install special rubber seals in the form of a cone. This will reduce the force at the clamping of the nuts, the tightness of the connection will have high reliability.
