Types of application provided by the design of the tap.

Modern taps can be designed for bath, shower, washbasin, bidet, kitchen, drinking water filter only and with the possibility of connecting to a filter. At the same time, many models are designed for several application formats at the same time — for example, functioning with a bathtub and a washbasin at the same time; and there are models without mixing water at all (with one connection pipe) — only for cold or only for already mixed water. More details in the separate paragraphs below.

— For bathtub. Taps used to fill the bathtub. Traditionally provided for wall mounting (see "Installation"), although there are exceptions in some specific models. In addition to a bathtub, such a tap can be used for a shower and/or a washbasin; in the first case, the design provides for the connection of a shower set, in the second, a long swivel spout that can be turned from the bathroom to the sink of the nearby washbasin.

— For shower. This option means that a shower set can be connected to the tap; sometimes such units are even supplied as a set (see "Spout design"). Specialized shower taps are exclusively wall-mounted or built-in (see "Install...ation"). At the same time, in addition to “shower-only” models, there are also “multi-purpose” products designed to be used simultaneously with a bathtub, and sometimes also with a washbasin (see “For bathtub” above).

— For washbasin. Specialized taps designed only for washbasins and have a relatively short spout, usually fixed, and can be installed in almost any way (except that floor models are a rather exotic option that has not gained distribution). Due to the similarity of washbasins with kitchen sinks, some models of a similar design can also be used as kitchen taps. Another, quite common, option is a hygienic shower for use with a bidet. Also note that the “washbasin” assignment can also be provided as an additional function in taps originally designed for bathtubs (see above).

— For kitchen. Taps for this purpose can be both highly specialized and provide other applications — for a washbasin (see above) or for a drinking water filter (see below). Anyway, such products are mounted mainly on a wall or tabletop, and the spout can be made quite high so that a pan or other large dish can be placed under. Also, in kitchen taps an interesting feature as a spring spout can be found (see "Spout design").

— For bidet. A bidet is a device in the form of a hygienic bath for washing the external genitalia and anus after going to the toilet. The classic bidet tap is installed directly on such a bath in a horizontal way (see "Installation"); the shape and design of the spout in such models is selected in such a way as to ensure effective ablution. However, in addition to this, the “bidet” category also includes specialized taps for a hygienic shower — a similar procedure carried out using a separate shower set. Such taps are built into the wall and do not require a separate bidet — a hygienic shower can also be used with a conventional toilet.

— For drinking water filter. Taps designed to supply drinking water from a tap filter, usually located under the kitchen sink. They are installed exclusively on the tabletop (see "Installation"), most often on the sink itself. Specialized models with only this equipment are distinguished by their small size and single-valve design (see "Tap type"). In addition, the possibility of connecting a drinking water filter can be provided as an additional feature in kitchen taps (see above). In such models, the spout has two holes — for "common kitchen" and for drinking water; each flow is controlled separately by its own valve (set of valves) or by a joystick.

— No water mixing. Taps that are designed to supply water at the still temperature. Outwardly, such models are no different from the classic ones: some are made with levers, others with a cross handle. But the key to them is the presence of only one pipe for supplying water. Accordingly, you can connect only cold, only hot or already mixed water.

Jet depth

Distance from the fixing point (for vertically mounted taps) or from the centre of the mounting hole (for horizontally mounted taps) to the middle of the spout. It is a characteristic that determines the "reach zone" of the tap.

Jet height

The jet height is usually specified for taps with horizontal installation (see "Type of installation"). It is measured from the base of the tap to the spout outlet. The large height of the spout is important primarily for kitchen models (see "Suitable for"), because it allows you to place large dishes in the sink. This parameter is directly related to the height of the spout (see above): the height of the jet cannot be greater than the height of the spout. Thus, in fact, one has to find a compromise between the height of the jet and the dimensions of the tap, especially if there is little space for its installation.

Features

The functions of the tap are mainly design features, among which the are check valve, bottom valve, cold start, LED backlight, temperature adjustment lever, display, auto-drain (hygienic flush), washer/dishwasher switch< /a>, shelves for accessories. In more detail:

— Check valve. The non-return valve prevents the flow of water through the tap in the opposite direction — for example, when there is a large pressure difference between hot and cold water. This function will be relevant for those who are going to install water metres: the presence of check valves on mixers is often a prerequisite for fulfilling an application for installation, because such valves prevent counters from spinning in the opposite direction. In addition, you should pay attention to the presence of a check valve in the tap (especially a single-lever tap, see "Tap type"), if there are interruptions in the water supply of your house — such taps behave much better in case of pressure surges in the water supply.

— Drain valve. A device that allows you to close the drain hole in the sink, kitchen sink or bidet (depending on the purpose of the tap). There are two types:

— Lever drain valve....To control the operation of such a valve, a small lever is used, located behind the tap, on the side of it or in front of the body. Raising and lowering it opens and closes the drain plug in the sink.

— Pressing drain valve. Valves of this type are locked and unlocked by pressing the drain plug, for which you need to wet your hand.

— Cold start. A feature found exclusively in single-lever models. The general principle of operation of the “cold start” is as follows: if you open the tap with the initial position of the joystick, it will not bring out mixed warm water (as in more traditional single-lever devices), but only cold water. To add hot water and raise the temperature, you need to deflect the lever from its initial position. Such a format of work can provide significant savings: by default, cold water comes out of the tap, and hot water is added to it only if necessary.

— LED light. Lighting system based on LEDs — an efficient and economical source of illumination. The purpose and functionality of such a backlight may be different. So, in some models, it is installed on the spout and directed downwards, which allows you to clearly see the space under the spout even in low ambient light. Sometimes such illumination also illuminates the stream of water, giving it an unusual appearance. There are also quite original systems — for example, with a transparent spout and LEDs at its base, which creates the effect of a tap glowing from the inside; and in some models, the lighting also changes color depending on the temperature of the water. However, anyway, this feature significantly affects the cost, so it is typical mainly for premium products.

— Autodrain (hygienic flush). Such a system is equipped with taps with additional electronics — mostly contactless models, as well as products with a thermostat or a button switch. The autodrain works as follows: at a certain rate (for example, once every 12 hours or once a day), the automation briefly turns on the water. Due to this, harmful bacteria are washed out of the device, which tend to multiply on the inner surfaces of the spout and in “stagnant” water inside the tap itself. At the same time, the consumption of water for hygienic washing is small, usually it is practically not noticeable against the background of general consumption.

— Temperature adjustment lever. A function found in taps, which design initially does not imply a temperature controller — primarily non-contact models, as well as in products with one main lever or with button activation (see "Tap type"). As the name implies, the temperature control lever allows you to use such a tap not only to control the pressure, but also to change the temperature of the water.

– Display. Taps that display temperature and/or current water flow. The display provides a clear visualization of the settings and allows you to see what kind of water and how much is flowing from the tap. However, the presence of the screen significantly affects the cost of the tap.

— Washer/dishwasher switch. A function that can significantly facilitate the connection of a washing machine or dishwasher to the water supply system. Taps with a washer/dishwasher switch have a separate pipe for connecting the dishwasher, as well as the switch itself, which allows you to open and close the water supply to this pipe. Thus, to connect a washing machine or dishwasher, you do not need to install additional bushings, splitters, etc. — just connect the device to an existing output. And you can control the water supply directly from the tap body, for this you do not need to get 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 found mainly in bath and/or shower taps (see “Suitable for”): it is convenient to keep shampoos, gels, soaps and other cosmetic/hygiene products on the shelf.

Note that this function is rare — mainly in high-end taps (in particular, thermostatic ones), which initially have large body sizes. In more traditional models, it makes no sense to include this design element — it is wiser to purchase a shelf as a separate accessory for the bathroom.
