Comparison taps

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.

The tap type is indicated by the type of controls installed in it. A number of features of both management and application in general depend on this. Nowadays, on the market you can find single cross handle, two cross handle, single lever (including those with additional touch control), non-contact and thermostatic taps, as well as push button models, which include both self-closing and thermostatic with a button. Here are the main features of these options:

— Single handle. Taps controlled by a single rotary handle (or a lever that moves in only one plane). In fact, they are not even "taps" as such, since they cannot mix hot and cold water and only regulate the pressure of the water supplied to them. It makes sense to use single handle models where the water temperature is constant and/or it makes no sense to regulate it — for example, in models for a kitchen filter (see "Suitable for"), for a washbasin where only cold water is used, or for an English-style washbasin, where hot and cold water is supplied from separate taps and mixed in the sink.

— Double handle. The classic design of taps, which does not lose popularity nowadays: two rotary handles responsible for...hot and cold water, respectively. This design is simple and inexpensive, while being reliable, moreover, it is convenient for precise temperature control. In addition, two handle taps are not afraid of the difference in the pressure of hot and cold water, and therefore it is recommended to use them with boilers. The disadvantage of this option is the impossibility of changing the pressure separately from the temperature and vice versa — any change requires turning both valves, while the pressure and temperature can fluctuate.

— Single lever. Taps where the flow of water is controlled by a single lever. Most often, turning the joystick from side to side in such models regulates the temperature, and tilting relative to the axis of rotation controls the pressure. This allows you to adjust the temperature without changing the pressure (and vice versa) and even “remember” the selected temperature option (just lower the lever to close without turning it sideways). At the same time, such devices are less accurate in adjustment than double cross handle ones.
Occasionally, you can also find a more specific variety — single-lever taps, supplemented by a separate temperature control lever (see below). In such models, the main joystick controls only the pressure.

— Push button. Models of mixers in which the control of turning the water supply on and off is assigned to a button. The first press turns on the water flow, the second turns it off. The button can be either an auxiliary means for conveniently turning on/off the water, or the main control element for the tap. In the latter option, to adjust the water supply pressure, the button is often made rotary.

— Self-closing. A variety of taps with button activation. However, here the button works on the principle of a timer: when you press it, water flows, and then a special mechanism gradually returns the button back, blocking the flow. Closing time is selected in such a way that one press allows you to more or less effectively wash your hands. Such devices are especially popular in public places, such as toilets of cafés, shopping centres, cinemas, etc.: there is no need to worry that an inattentive visitor will forget to turn off the tap. Most often, these taps are single-temperature, but there are also models with a temperature adjustment lever (see below).

— Thermostatic. Taps that have a thermostat function — that is, capable of automatically maintaining the temperature set by the user. Such models are extremely convenient: when the pressure or temperature of the water in the pipes fluctuates, you do not need to fiddle with the settings — the device will independently select the operating mode so that the outlet temperature does not change (or at least these changes are minimal). The main disadvantage of thermostatic models is the complexity of the design and, as a result, the high cost. In addition, many of them require an electrical connection. For control, models may include rotary controls or a button (see above).

— Non-contact. Models operated in a non-contact way — without the need to touch the device. This format of operation is most popular in washbasin taps (see "Suitable for"): in such models, a sensor is used that reacts to the presence of the user's hands under the spout. This is especially convenient in common areas where it is undesirable to touch the tap once again. There are other types of non-contact models — in particular, devices for the kitchen or shower. In the first case, it can be inconvenient to open an ordinary tap with dirty hands after kitchen work. At the same time, the control may not be completely contactless — there are devices with valves or other equipment for pre-setting the temperature, while the sensor in them works only as a water flow switch. And touchless shower taps necessarily have an additional control for setting the temperature; the sensor in them reacts not just to the hands, but to the whole person.

— Single-lever + touch. A variety of single-lever mixers (see above), equipped with an additional switch. As in conventional single-lever models, the joystick in such devices is used to adjust the pressure and temperature; the difference lies in the fact that the water is opened not by a lever, but by the mentioned switch. In other words, it is enough to set the optimal pressure and temperature once using the joystick — and then you can turn on the water by simply touching the switch. The device of the switch itself can be different: in some models, the entire tap's body plays its role, in others a special button or even a foot pedal is provided. The exception is the non-contact models described above — they may be similar in design and method of use, but all the same, these taps are classified into a separate category.

— Waterfall. In such spouts, water is supplied through an outlet in the form of a thin horizontal slot, or through a wide chute (depending on the model). Due to this, a large width of the jet is achieved with its small thickness, which provides good throughput, as well as an original appearance — the waterfall tap actually imitates a waterfall (hence the name). On the other hand, this type is less universal than the classical one, and it costs significantly more, and therefore is used quite rarely. Basically, waterfall spouts are used for bathtubs (due to their high throughput), there are also models for washbasins (see "Suitable for").

— Without spout. Models of taps that do not have a spout. Foremost, this applies to models for the shower, where mixing and water supply are provided for a shower head or overhead shower.

In most cases, the spout is classic, made in the form of a tube. Such spouts can have different shapes in length (straight, curved, with an angle) and cross-section (round, triangular, square, etc.), but all of them are just tubes.

Material and design features of the valve (valves) responsible for opening and closing water in the tap.

— Rubber. Valve material for low-cost one- and two-valve mixers (see “Product type”). Rubber is inexpensive, easy to replace, and resistant to contaminated water (unlike ceramics). On the other hand, rubber valves have a relatively short service life — when they wear out, they begin to leak, and they have to be changed time to time.

— Ceramic. These valves are based on a pair of ceramic-metal plates polished for maximum contact and tightness. They can be used both in cross-handle and lever taps (see "Product type"). This material is much more durable than rubber, and in the case of a single-lever tap, it also makes adjustment easier, because the friction between the plates is low, and it is much easier to move the lever than with a ball valve. The disadvantage of ceramics is the sensitivity to water contamination by solid particles — getting between the plates, they can break the tightness of the valve. Therefore, it is recommended to install filters in front of such taps.

— Electromagnetic. A type of valve used in all non-contact mixers (see "Product type"), as well as some models of a different design — in particular, push-button and single-lever with touch. As the name implies, an electromagnet is responsible for opening and closing water i...n such models. At the same time, the valve in most models has only two positions — “open” and “closed” — and does not imply pressure adjustment. But the temperature controller can be provided — for example, in the form of an appropriate lever (see above). Electromagnetic valves are quite efficient, but expensive and require external power to operate.

— Ball valve. A type of valve originally developed for single-lever taps (from which the tendency to call such devices "ball valves" came from, which is not technically correct). At the heart of such a valve is a spherical element with a special slot through which water is supplied; when the lever moves, the slot occupies one position or another, on which the pressure and temperature of the water depend. In domestic taps, this type of valve is considered obsolete and is rarely used.

In most cases, this is not one accessory, but a whole set that allows you to use the tap for showering. A mandatory element of the shower set is a shower head, in most cases it is supplemented with its own hose. In addition, the design may provide a mount for a watering can — on the wall or directly on the tap's body (for the second option, see below). But the purpose and functionality of the shower set may be different, depending on the specialization of the tap itself (see "Suitable for"). So, in bath and shower models, water can be supplied either through a spout or through a shower set, and an appropriate switch is provided for selection (sometimes automatic, see below). Shower-only taps do not have this switch. In models for washbasins, the shower set is designed for the so-called hygienic shower — washing certain parts of the body (primarily the groin area, etc.); the watering can for such a shower is small in size and is equipped with its own button that turns the water on and off. There are even kitchen taps with this function — the shower performs the same function as the pull-out spout. And the number of modes may not be limited to one. Several hand shower modes allow you to get a shower water jet of your favour — from classic small streams to one continuous stream, with all sorts of variations. The more settings provided, the wider the choice.

The length of the hose provided in the design of the tap. This is a secondary parameter, since the hose is selected by the manufacturer in such a way that it is comfortable to use it for its main purpose — for taking a shower. But for tall people, the standard length may not be enough, so it is appropriate to know its dimensions for greater comfort and ease of use.

Installation type for which the tap is designed. Nowadays, wall and sink taps (classic, freestanding and under the window), as well as built-in solutions, are most widely used — usually with installation in the wall, less often horizontally. Models built into the wall can be equipped with a bar(it plays the role of a kind of body and combines all the elements of the tap) or can be supplied without a bar(this option often allows you to choose the distance between the separate parts of the set). A special, rather rare and specific variety are floor taps.

Here is a more detailed description of each option:

— Wall (vertical). Models designed to mount to a vertical surface, typically a wall. This installation method is found mainly in bath and/or shower models, but can also be used in other types of taps— in particular, kitchen ones.

— Sink (horizontal). Installation on a horizontal surface such as a washbasin or kitchen sink. This method is extremely popular in models for kitchens and washbasins, it is also used in traditional bidet taps, but in other varieties, for a number of reasons, it has not gained much popularity.

— Sink (under the windo...w). A special kind of taps, which, due to their design, can be installed under the window, without preventing it from opening and closing. This is achieved in two ways. The first is the ability to tilt the spout towards the washbasin or sink, thereby hiding the tap in the sink bowl. The second method is based on a special mount of the tap body to its base, which makes it easy to pull it out of the “base” and put it next to it.

— Built in (wall). Mounting method in which most of the structure is hidden behind a wall or other vertical surface. Outside, there are only elements for which it is essential: spout, valves, shower set, etc. Recessed installation provides a neat appearance and saves space. In addition, many models of such taps allow you to choose the distance between individual external elements and their relative position. However, embedding is noticeably more difficult than usual installation, and repair/maintenance of such a tap can be quite difficult. This option is used in models for baths, showers, washbasins, as well as some types of bidet taps (see "Suitable for").

— Built in (horizontal). Another type of built-in taps, designed, in accordance with the name, for installation on a horizontal surface. They have the same main advantages and disadvantages as the in-wall taps described above, but differ in specialization: this type of installation is most popular in “washbasin only” models, it is somewhat less common in bath and shower taps.

— Floor. Installation on the floor using a special stand, thanks to which the main part of the tap is placed at the desired height. Such models are expensive, and the installation itself is quite complicated, it requires a spacious room with a specific organization of plumbing. Therefore, this option has not received much distribution: it is used mainly in designer taps made for freestanding bathtubs or washbasins.

The type of water pipes the tap is designed for.

— Hoses. With a flexible connection type, polymer tubes (hoses) are used to connect the tap to the water supply, which can bend well and are reinforced with a metal mesh for strength. This ensures ease and versatility of attachment — thanks to the flexibility of the pipe, it can be carried even in cramped places. On the other hand, such a supply is less durable and reliable than a rigid one. It is mainly used in models for kitchens and sinks (see "Suitable for"). Installation pipes may be included in the package of the tap; this point should be clarified separately.

— Rigid pipes. Such taps are designed for installing directly to metal water pipes. The advantage of this type is reliability and strength, the disadvantage is significant restrictions on the installation site: you either have to put the tap where the pipes were made during construction, or redo the communications, which is associated with great inconvenience and cost. On the other hand, such taps are usually used for bathtubs and showers, and in modern bathrooms, typically there are no problems with unsuccessful installation of pipes.

— Brass. Alloy based on copper and zinc; at a relatively low price, it has good strength and corrosion resistance, due to which it has become widespread.

— Silumin. An alloy based on a combination of aluminium and silicon; it has good hardness and oxidation resistance, but it is rather brittle, and therefore it is used mainly in inexpensive models.

— Stainless steel. The most common material for inexpensive models. Steel is inexpensive and at the same time has high strength. Its disadvantage is a certain tendency to corrosion (especially with processing defects, even small ones), which practically does not affect everyday use, but can affect the durability of the tap.

— Zinc. Zinc products are similar in their main properties to the silumin products described above: on the one hand, they are inexpensive, on the other hand, they are quite fragile and not particularly durable. In addition, zinc is believed to be prone to corrosion, which can eventually degrade the properties of the water coming from such a tap and make this material unsuitable for kitchen use. Therefore, zinc bodies are not common, mainly among inexpensive bath and shower taps.

— Plastic. The simplest material used in the manufacture of taps. Due to its weak strength, it is not durable, but it does not rust. It is appropriate to use for sinks of rare use — for example, for a country house.
