Size
The size of the overhead shower head supplied in the set (see "Complete set"). For round watering cans, this paragraph indicates the size, for other shapes - the length (the largest of the two main sizes).
The larger the overhead shower - the more space it covers, the easier it is to "fit entirely" under the jets and the higher the throughput can be (see "Water consumption overhead shower"). On the other hand, the cost of a watering can directly depends on the dimensions. As for specific figures, the size
up to 20 cm is relatively small, although such watering cans are very popular due to their availability and low consumption. Models
21 - 25 cm can be classified as medium,
26 - 30 cm - relatively large, and the largest watering cans for the overhead shower have dimensions
of more than 30 cm.
Water flow
Water consumption during operation of the upper shower (cf. «Equipment»). Indicates the amount of water passing through the watering can with the tap fully open and the water pressure 3 bar (standard household water pressure).
The higher the bandwidth of the watering can be - the more powerful and intense the shower becomes. On the other hand, high water consumption is undesirable if you want to save water - for example, if you have meters installed or if water is supplied from a boiler with a small volume. In addition, it is worth remembering that the watering can have different settings and features of water supply. So, by selecting the lake with the right parameters, you can get a nice and effective top shower even when
low water flow. Actually, a low value in this case is considered to be up to 10 l /min; the average is 10 - 20 l/min, and in the most productive watering can be up to 30 l/min and even more.
Tilt angle
The top shower angle is tilted in both directions. Not all models have adjustment, and even those in which it is constructively laid have different angles. By itself
the ability to adjust the inclination angle of the upper shower allows you to adjust the flow of water to the desired side for the needs of a particular user.
Size
The size of the manual or hygienic shower head can be found (cf. «Complete»), which is equipped with a shower system. In fact, it implies the size of the working area - the area on which the nozzles for water supply are located. If this area is round or square, its size is indicated by diameter or width, for other shapes - by length.
Big size allows to cover more space at once; on the other hand, more compact models are more efficient, and cheaper, all other things being equal. And hygienic watering cans, taking into account the specifics of their use, by definition are made
small.
Jet settings
The number of
jet settings provided in the complete manual or hygienic watering can (see "Complete set"). However, hygienic leukemias are usually made
single-mode - this is quite enough considering the application. But in conventional manual waterjets can be several, which allows you to change the characteristics of the jet at the request of the user - for example, instead of the usual thin jets, turn on a hard jet from a single large nozzle or a solid «soft» Flow from water filled with air bubbles. The specific set of settings can be different, it is worth to refine separately. However, in any case, the more options - the wider the choice of the user and the more complicated and more expensive the watering box itself.
Water consumption
The throughput capacity of a manual shower watering agent, in other words, the amount of water it gives out per minute when the faucets are fully open. Since the capacity is not only related to the design of the watering box, but also to the pressure in the water supply, it is customary to specify an average value - at a standard pressure of 3 bar.
The higher this parameter - the more intense the impact on the body can have a shower. At the same time, high water consumption can become a problem when there are water meters or when there are limited supplies - for example, if hot water is supplied by a boiler. Also note that
, low throughput can be compensated by certain jet settings.
Check valve
Check valve prevents the water from moving through the mixer to the opposite direction - for example, when there is a large pressure difference between hot and cold water. This feature will be relevant for those who are going to install water meters: the presence of non-return valves on mixers is often a prerequisite for fulfilling the installation request.
