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.
Min water pressure
The lowest inlet pressure at which the tap is able to fully perform its functions of unhindered water supply.
Max water pressure
The highest inlet pressure at which the tap is able to operate in a trouble-free mode with minimal risk of premature failure. In other words, this is the ultimate strength of the tap. Note that for normal east european use, it can be assumed that the maximum pressure in the water supply is 6 bar. One should focus on that value and choose a model with a small margin of max pressure in order to avoid leaks in the tap nodes during pressure surges in excess of the norm. Note that in plumbing with a centralized water supply, the pressure can reach 10 bar. Therefore, for expensive taps that make high demands on the inlet pressure, it is necessary to buy special reduction gears.
Installation
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.Inlet communication
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.
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).
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.
