Comparison Jacob Delafon Kumin E99465 vs Ferro Ibiza BIB2

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.

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.

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.

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 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 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.
