I would like to note right away that the very idea of such equipment has been known to the world for a long time. You have probably come across similar developments somewhere in public toilets (at large airports, in the toilets of hotels and inns, cinemas, shopping centers, etc.). They know exactly how to save on water.
The bottom line is simple: I put my hands under the tap - the water ran, removed it - the water stopped running.
Now, you can implement this idea in your home without having to buy expensive plumbing fixtures and completely change all the plumbing in your home. It is enough to purchase a compact and convenient “Vodoeconom”.
It is not expensive compared to special faucets and faucets in which a photocell is built in and which you could observe in the public places listed above, but it performs the same functions.
In addition, this touch nozzle will fit almost any faucet and faucet located in your home.
Let's take a closer look at it...
Here's what's included in the package:
In addition to the device itself, a special adapter is included in the kit, with the help of which this water-saving nozzle fits absolutely on any faucet. This nozzle is double-sided, has an internal and external thread. It is inserted instead of the standard aerator mesh, which is located on the spout of almost any mixer.
ATTENTION! If your faucet does not have an aerator mesh and a thread on the end of the gooseneck, then this water saver sensor nozzle will not work for you!
The scheme for mounting the nozzle on the faucet is as follows:
- You unscrew the aerator mesh from the gander of your mixer
- Then, instead of the mesh-aerator, you screw in the adapter that comes with the sensor nozzle
- After that, the sensor nozzle Water Saver (Water Saver) is screwed to the adapter

What does this sensory attachment do?
This device is powered by 4 AAA batteries. One set of batteries is enough for 6-12 months of continuous operation. The cost of one set of batteries in the M.video online store is only 91 rubles.
Even if you spend two sets of batteries in a year, that is, 182 rubles, we dare to assure you that the cost of them will be recouped in just a month. More detailed calculations of the payback of the device and batteries will be below.
Now let's look at how and where the batteries are inserted:
Batteries are inserted into a special battery compartment, which is attached to the back of the nozzle. The compartment is held securely inside the nozzle, but at the same time it is quite easy to remove from there. The compartment has a special ledge, which you need to take with your fingers and drag it towards you.

How does this device work?
This device has a touch sensor that responds to movement.
This sensor is adjustable. You can set the sensor to trigger at a distance of 7 cm to 25 cm.
Two operating modes
The water-saving sensor nozzle works in two modes: manual mode and automatic mode.
- Manual mode necessary in cases where you pour water into a kettle, or a pot, a bucket. That is, when you need a continuous flow of water, turned on and off manually through a tap.
- Auto mode works when you need water supply only when your hands or objects that you need to wash are under the tap.
Turning the modes on and off is done through this button:
By the way, the same button will tell you if your batteries are low.
Subtleties of operation of the sensor nozzle Water saver
Before you make a purchase decision, we must warn you about some subtleties that may not seem very convenient to you.
For the most efficient operation of this device, it is necessary to install water return valves in the event that you have different water pressure in the pipes.
And now let's try to explain it in simple and accessible words. The fact is that in most pipelines throughout Russia, water is supplied with different pressures, with different pressures. Hot water with one pressure, and cold with another.
As a result, if you use the sensor head without water return valves, you may experience a "water squeezing effect". Let's say you put the sensor nozzle on the faucet, set a comfortable water temperature and went somewhere for a minute. At the same time, the mixer valves did not close, but the water does not flow, as it is held by the sensor nozzle. At this point, a confrontation between hot and cold water will begin inside the tap.
The water that comes with more pressure will begin to squeeze out the one that is supplied with less pressure. As a result, when you come to the faucet after a while, water will not run at the temperature that you set, but either boiling water or cold water, depending on which pipe the pressure is stronger. This will continue until the squeezed out water exits the system and only after that you will get water from the tap at the temperature that you set up earlier.
You will also see the pressure difference in the pipes on your counters. At the moment when the tap is idle, when again the valves are open, but the water is retained by the nozzle, one of the counters will rotate clockwise, and the second counterclockwise, as if rewinding.
This problem can be solved with the help of water return valves. They are also called check valves. The essence of their work is simple: they allow water to pass in the right direction, but do not allow it to go out in the opposite direction, that is, to be squeezed back into the pipeline. They are not expensive. One valve in our online store costs 150 rubles.
Installing the valve can be easy or complicated depending on where you will have the sensor head:
- If the water-saving sensor nozzle will stand in the kitchen, then installing a check valve here will be simple. Under the sink from the faucet you have two flexible hoses that connect to pipes with hot and cold water. The valve is placed between the hose and the pipe. That is, you need to first block the risers, unscrew the flexible hose from the pipe, then screw the valve to the pipe with one end, and attach the flexible hose to the other end.
- If you are going to install a water-saving sensor nozzle in the bathroom and at the same time you have a faucet connected to pipes that are "hidden" in the wall, then installing valves will be more difficult here. It makes no sense to screw the valve between the mixer and the pipe hidden in the wall, as this will not be aesthetically pleasing. Therefore, in such cases, the valve is placed immediately after the counter. If in the first option you can handle the installation of the valve yourself, then in this case you will have to call a plumber.
In any case, the cost of installing water return valves, as well as the sensory nozzle, will be beaten off from you in the first year of using this economical device.
