Water flow
The maximum water flow during the operation of the tap, in other words, the maximum amount of water that it can pass through in a minute. This characteristic is important, foremost, for models designed for baths (see "Suitable for"): the greater the throughput, the faster the bath will fill. However, the meaning of this paragraph is not limited to this. First, flow information can be useful in certain calculations related to water supply — for example, to calculate the required pump capacity. Secondly, high-end taps can be equipped with aerators to achieve a powerful and efficient jet with low water consumption; the consumption indicated in the characteristics allows you to evaluate the efficiency of such devices in comparison with analogues.
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.
Shower set
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.
