Comparison Ferro Vasto BVA2A vs Ferro Vasto BVA2

— Straight. Spout that have straight or almost straight shape and directed almost horizontally (other arrangements are highlighted in a separate paragraph — see “At right angle”). Generally, such a spout combines simplicity, practicality, and versatility. In particular, it can be of any length, and can also be rotary (see “Spout”), while being inexpensive to manufacture. Nowadays, straight spouts are extremely popular, and in almost all types of taps (see “Suitable for”). The exception is perhaps the kitchen application: this form is inconvenient for washing dishes by itself and leaves less space for dishes in the sink than other shapes (for example, angled or gooseneck spouts).

— Gooseneck. Taps with a spout in the shape of an arc, usually semicircular and rather steep. This design is most popular in kitchen taps, as it provides the necessary space for washing large dishes. Many models with such a spout are designed for washbasins — they also use a vertical installation, for which the arc is very convenient. And gooseneck bath taps are most often original premium models installed directly on the side of the bath (also horizontally).

— L-shaped. Spout in the shape of the letter “L” — with a vertical base and a horizontal “crossbar” extending from it. Thanks to this shape, the spout can be positioned at a sufficiently high height, which is especially conveni...ent when used in the kitchen or with a washbasin. Most of the L-shaped models refer to these specialization options (see “Suitable for”). According to the type of the tap (see the corresponding list), they are usually single-lever, while the joystick is located on the side; however, there are other options — both in the location of the joystick, and in the type of control.

— U-shaped. Spouts of this category resemble L-shaped models (see the relevant paragraph), in which the end of the spout is noticeably bent downwards. This gives them an original shape, as well as some resemblance to gooseneck models. U-shaped spouts are typically taller and are intended for use in kitchens or washbasins. At the same time, they are not as popular as the mentioned L-shaped ones, and even more so the gooseneck ones. In particular, because of the higher cost with no obvious practical advantages (although this form may well be optimal in terms of design).

— S-shaped. A variant that is predominantly found in bath models (including bath and washbasin solutions) as well as in some kitchen taps. The spout in this arrangement has the shape of the letter “S”, laid “on its side”. This design is well suited for wall-mounted models, where the spout outlet must be placed noticeably below the tap itself.

— At right angle. A straight spout located at a right angle relative to the tap body — directed from the base of the body up or down. This shape is especially suitable for washbasins and kitchens, and it is mainly found in taps of those specializations (see “Suitable for”). Most models with a similar spout have a fairly modern appearance, thanks to that they fit well into modern, high-tech interiors, etc.

— Curved at an angle. A spout that leans upward from the base of the tap and curves slightly downward at the end. The shape is in many ways reminiscent of the “at right angle” option, but it has its own characteristics. Firstly, such a spout can be made somewhat longer, which is convenient for kitchen use: the outlet is at a sufficiently high height and there is enough space under it to wash even large dishes without any problems. Most of the models in this category are just made for the kitchen. Secondly, for some users, this form is preferable from an aesthetic point of view (although, of course, this is a matter of personal taste). These spouts look more “cheap” compared to the products of the “at right angle” form factor and are extremely rare among top plumbing brands.

— Vertical jet. This type of spout is found among bidet taps. It involves vertical spraying of a water jet for taking a hygienic shower after visiting the toilet. The mortise vertical spray module is installed separately from the tap. Usually, the design also assumes a water return valve.

— Connected to overflow. Taps with a spout in the form of a flexible hose that connects to the overflow of the bathtub, and the water is poured through it. Thanks to such taps, minimalism is ensured in the appearance of the bathtub, which is caused by the absence of a classic spout. In addition, there is no need to make extra holes in the side of the bathtub to install the tap.

Possibility to turn spout from side to side. In this way, you can change the location of the water jet, which can be useful in a variety of cases. This feature of the swivel spout is most popular in two varieties. The first is bath and washbasin devices, where one spout serves both the bathtub and the washbasin. The second is kitchen taps: the ability to rotate the spout is important in order to place large dishes in the sink.

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 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.

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).
