A water aerator is a device designed to reduce water consumption in an apartment. It is available as a faucet attachment. Promotes saturation with oxygen and volatilization of chlorine from the liquid.
Let's understand the principle of operation of the device and find out if the nozzle is suitable for saving water.
What's the secret
Almost all mixers have a built-in aerator for:
- breaking the jet into small streams;
- saturating it with air;
- reduce the amount of splashes that fly around the sink.
It is a fine mesh that is wound on a faucet or mixer tube. This is the base model.
How to save
To understand how nozzles work to save water, you need to understand their structure and principle of operation. The device consists of several parts:
- cover plate - restricts the flow;
- mesh plate - saturates the jet with oxygen;
- springs designed to adjust the flow of water;
- inner and outer case;
- screws for connecting individual nodes.
The device works due to the pressure difference:
- the liquid, passing through the cover plate, creates a high pressure regulated by a mesh plate;
- under the mesh accumulates air entering through the side walls;
- flow is mixed with air.
Mixing occurs in a ratio of 1:3, which reduces fluid consumption.
Air Sellers
Let's find out if it is really beneficial to use a water aerator. The main consumption falls on the kitchen, shower and toilet. The appliance is designed for installation on a water tap only. Directly from the tap, water is needed to wash, wash hands or dishes. It accounts for about 10% of all consumption. Gathering a kettle or a pan to save money will not work, because displacement is important here.
Consider an example. The average family of four consumes about 24 cubic meters of water. In the calculation, we will proceed from the fact that for cold and hot water the indicators are equal. Let's take the average rates in Moscow:
- 130 rubles - hot water;
- 35 - cold;
- 30 - drainage.
Then it turns out:
(130 x 12) + (35 x 12) + (30 x 24) = 1560 + 420 + 720 = 2700 rubles.
10% of the total amount will be 270 rubles, taking into account the fact that the aerator saves 50% - 135 rubles. But manufacturers promise a 50% reduction in water consumption in general.
The lineup
Having decided to purchase an aerator nozzle, look at the official websites for offers from companies:
- Premium (Germany);
- Terla - Premium (Italy);
- Eco-standard (Germany);
- Tescoma and others.
These are compact aerators that turn the water jet into a soft stream.
Aerators are truly water-saving because they don't allow splashes to form. If you wash your hands or dishes, then really air-saturated water will be spent less. But saving and saving are two different things. These concepts, close in meaning, are often used not very honestly.
In some reviews, buyers write that they did not notice much difference, and if there is, then no more than 10-20%.
