Lever
—
Feather. Single-lever faucets, in which the joystick lever for controlling the flow of water is made in the form of a small narrow stick. It resembles a pen in shape and structurally enters directly into the cartridge (unlike conventional models, where such a lever is part of a plate that is attached to the cartridge). The pen can be placed both vertically and horizontally (depending on the design of the mixer). At a minimum, these products have an unusual appearance, and for some users, a joystick pen may be more convenient to use. On the other hand, such joysticks are found mainly among premium mixers.
—
Elbow (medical). Taps with a water regulation lever of an unusual shape, easy to use with your elbow. Such models are especially in demand in medical institutions, when the hands of a medical employee must always be clean and close the tap with them — already a violation of hygiene standards.
—
Joystick with a hole. The characteristic hole in the handle of single-lever taps plays both a decorative role and a practical one. For some models, it serves as a design element of the tap, and in general, the hole can be used to conveniently adjust the pressure and temperature of the water (by prying with a finger and then turning or raising/lowering the lever).
Features
The functions of a mixer mainly consist of design features, among which are the presence of a
check valve, a
pop-up waste,
cold start,
LED lighting, a
temperature control lever, a
display,
auto-drain (hygienic rinse), a
switch for washing machine/dishwasher, and a
shelf for accessories. More details:
— Check valve. A check valve prevents water from moving backward through the mixer, for example, when there is a significant pressure difference between hot and cold water. This feature is relevant for those planning to install water meters: the presence of check valves on mixers is often a mandatory condition for installation requests, as such valves prevent meters from running backward. Additionally, it's worth noting the presence of a check valve in the mixer (especially single-lever ones, see "Mixer Type") if your home's water supply is prone to interruptions — such mixers perform much better during pressure surges in the plumbing.
— Pop-up waste. A device that allows you to close the drain hole in a sink, kitchen sink, or bidet (depending on the purpose of the mixer). It comes in two types:
— Lever pop-up waste. This type of valve is operated by a small
...lever located behind the mixer, to the side, or at the front of the body. Raising and lowering it opens and closes the sink's drain plug.
— Push-button pop-up waste. Valves of this type are locked and unlocked by pressing the drain hole plug, which requires wetting your hand.
— Cold start. A feature found exclusively in single-lever models. The general principle of "cold start" is as follows: if you open the mixer with the joystick in the central (default) position, only cold water will flow out, not mixed warm water (as in more traditional single-lever devices). To add hot water and increase the temperature, you need to move the lever from the default position. This operation format can provide noticeable savings: by default, cold water flows from the mixer, and hot water is added only as needed.
— LED lighting. A lighting system based on LEDs — an efficient and economical light source. The purpose and functionality of such lighting can vary. In some models, it is installed on the spout and directed downward, allowing you to see the space under the mixer well even in low external lighting. Sometimes this lighting also illuminates the water stream, giving it an unusual appearance. There are also quite original systems — for example, with a transparent spout and LEDs at its base, creating the effect of a mixer glowing from within; in some models, the lighting even changes color depending on the water temperature. However, in any case, this feature significantly affects the cost, so it is mainly characteristic of premium-class products.
— Auto-drain (hygienic rinse). This system is equipped in mixers with additional electronics — mainly contactless models, as well as products with a thermostat or button activation. Auto-drain works as follows: at certain intervals (for example, once every 12 hours or once a day), the automation briefly turns on the water. This washes out harmful bacteria that tend to multiply on the internal surfaces of the spout and in the "stagnant" water inside the mixer. At the same time, the water consumption for hygienic rinsing is small, usually almost unnoticeable against the background of overall consumption.
— Temperature control lever. A feature found in mixers whose design initially does not include a temperature regulator — primarily contactless models, as well as products with one main lever or button activation (see "Mixer Type"). As the name suggests, the temperature control lever allows you to use such a mixer not only for controlling the flow but also for changing the water temperature.
— Display. Mixers that display the temperature and/or current water consumption. The display provides a clear visualization of settings and allows you to see what water and in what volume is flowing from the tap. However, the presence of a screen significantly affects the cost of the mixer.
— Switch for washing machine/dishwasher. A feature that can significantly simplify the connection of a washing machine or dishwasher to the water supply system. Mixers with a switch for a washing machine/dishwasher have a separate pipe for connecting the machine, as well as a switch that allows you to open and close the water supply to this pipe. Thus, to connect a washing machine or dishwasher, there is no need to install additional bushings, splitters, etc. — just connect the device to the existing outlet. And you can control the water supply directly from the mixer body, without having to crawl under the sink or into another hard-to-reach place.
— Shelf for accessories. Most often, the role of such a shelf is played by the upper part of the body, specially made flat. This feature is mainly found in mixers for baths and/or showers (see "Purpose"): it is convenient to keep shampoos, gels, soap, and other cosmetic/hygienic products on the shelf.
Note that this feature is rare — mainly in high-end mixers (in particular, thermostatic ones) that initially have large body sizes. In more traditional models, there is no point in providing this design element — it is more reasonable to purchase a shelf as a separate accessory for the bathroom.Water flow
The maximum water flow during the operation of the tap, in other words, the maximum amount of water that it can pass through in a minute. This characteristic is important, foremost, for models designed for baths (see "Suitable for"): the greater the throughput, the faster the bath will fill. However, the meaning of this paragraph is not limited to this. First, flow information can be useful in certain calculations related to water supply — for example, to calculate the required pump capacity. Secondly, high-end taps can be equipped with aerators to achieve a powerful and efficient jet with low water consumption; the consumption indicated in the characteristics allows you to evaluate the efficiency of such devices in comparison with analogues.
Diverter
A diverter is a device that switches a water flow between spout and shower head. The design of such a device and the way it is controlled can be different, in modern taps you can mainly find the following options:
— Button. Diverters of this type have the form of a button; but its design depends on the characteristics of a particular tap. In relatively simple mechanical models (most of them), the button is also made mechanical, and to switch from spout to shower, you need to pull it up. And switching in the opposite direction — from a shower to a spout — can often be carried out not only manually, but also automatically, when the water is turned off (see "Features — Shower / bath auto switch"). In some taps, auto-switching can also be blocked by the user (usually by turning the button in the up position).
In turn, in advanced electronic devices, such a diverter is made in the form of an electric button that closes the contacts that control the valve.
— Lever. Diverter in the form of a rotary lever. Most often, this lever directly controls the valve that switches the flow of water. This design is considered somewhat less reliable than push-button, but it is much simpler and cheaper, which makes it very popular — especially in relatively inexpensive taps. But in premium devices, this type of diverter can operate according to other, more advanced principles — for example, a lever can work as an electronic switch.
— Turning the spout. A r...ather rare and specific option: the role of the lever that controls the flow of water is performed directly by the spout, to the base of which a shower hose is connected. Such a control, usually, works as follows: while the spout is perpendicular to the tap body, water flows through it, and to switch to the shower, the spout turns, being under the tap. Such devices look interesting, and are convenient to use. On the other hand, they are quite complex and expensive, and the spout itself, for a number of reasons, is typically made quite short. Therefore, this variant has not gained popularity.
— Removable. A diverter located outside the body — usually between the tap itself and the spout. Typically, on one side of such a device there is a control element (most often a small lever or a rotary tap), and on the other, a pipe for connecting a shower hose. And the name "removable" suggests that this part can be easily removed if needed — unlike, for example, push-button or lever solutions, which are usually built directly into the tap body and are very difficult to dismantle or replace. Accordingly, after removal, the diverter can either be replaced with another one, or removed altogether by connecting the spout directly to the tap. This is the main advantage of this option: in case of malfunctions in the diverter, it can be removed without any problems for repair or replacement, while the tap (with the exception of the “shower part”) remains fully operational.
Tap height
The height of the tap, measured from its base or lowest point to the highest point of the spout. The height of the spout partly determines the installation possibilities — in fact, this is the minimum vertical free space that is required for the tap. In addition, in models with horizontal installation (see "Type of installation"), the spout height is related to the jet height (see below).
Country of brand origin
Country of origin of the brand under which the tap is marketed. Usually, it is indicated by the "homeland" of the manufacturing company or by the location of its headquarters. The brands under which modern mixers are produced come mainly from the following countries (in alphabetical order):
Austria,
Belgium,
Germany,
India,
Spain,
Italy,
China,
Poland,
Russia,
Turkey,
Czech Republic,
Finland,
France,
Sweden.
There are many stereotypes associated with the “nationality” of brands and products, but most of them have no basis nowadays. First, the actual place of production is often different from the brand's country of origin. Secondly, the quality of the goods depends not so much on geography, but on the policy of a particular company and how carefully this very quality is controlled in it. Therefore, you should pay attention to the country of origin of the brand only if you fundamentally want or (do not want) to support a manufacturer from a certain state. Quality is best judged by the reputation of a particular
...brand and the overall price category of the tap.Manufacturer's warranty
The warranty period claimed by the manufacturer for a certain tap model is the period during which the manufacturer guarantees the normal operation of the device. The specific terms of the warranty may vary, however, usually, it covers factory defects and malfunctions caused by the fault of the manufacturer or seller and discovered during normal use, without violating the rules; if such defects or malfunctions appear during the warranty period, the manufacturer undertakes the obligation to correct the situation at its own expense — up to replacing the tap with a working one.
Nowadays, you can find taps with a guarantee of
4 years,
5 years,
7 years,
10 years and even
25 years. In general, the longer the warranty period, the more reliable the product is, the higher its overall quality, ceteris paribus, but the more expensive it will cost compared to analogues.
