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.
Spout
— Cascade. In such vents, water is fed through an outlet in the form of a thin horizontal slit, or a wide trench (depending on the model). Due to this, the output achieves a large width of the jet at a low thickness, which provides a good throughput, as well as the original look, imitating the waterfall (hence the name). On the other hand, this form is less universal than the classical one, and it is much more expensive, and therefore is used quite rarely.
— Classic. Models in which the spout is made in the form of a tube. Such flows may have different shapes in length (straight, curved, with an angle) and cross-section (round, triangular, square, etc.), but they are all tubes.
In most cases, there is simply no drain for shower systems.
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.
