Emergency water shutoff valve in case of leakage. Protection against water leakage "Neptune

17.06.2019

Anyone who has had to deal with a situation of emergency water leakage knows how many problems an unclosed tap, leaks in the water supply and heating system can bring. Water leakage causes major financial problems, conflicts with neighbors and the need to make repairs. In addition, the wiring can fail, shorting out all electrical appliances, electric shock and serious injury can occur. But the engineering inventions of flood protection devices perform the functions of protection against leaks and avoid such unpleasant situations. Leak protection complexes have been developed, which, having similar functions, are in different demand. Let's consider in detail each of the systems most in demand today.

The principle of operation of the leakage protection system

The protective mechanism consists of the following main parts:

Control block;
water flow sensors;
taps that automatically shut off the flow of water in the water supply system and the heating system.

The principle of operation of protective equipment is simple. Signal sensors are located in places of possible leakage. Most often, this place is under the bathtub and sinks, washing machines and water heating complexes. When in contact with water, in case of leakage, a signal is sent to the central unit, which acts as a controller. In this case, the controller gives a signal about emergency and a quick shut-off valve prevents water from entering the system.

Installing a leak protection system

A mechanism based on only three important element: sensors, controller and pilot valve, easy to mount, with standard mounting procedure.

Before starting the installation, you must carefully read the instructions for the mechanism, learn the features of installation and use of the device. The layout of the device and its components should be placed taking into account the characteristics of the dwelling and the location of places with a likely leak. The elements should be arranged taking into account the permissible length of the wires; if the length is insufficient, the wire elements can be increased. Among the two options location of the mechanism, underground location is recommended. This will not affect the aesthetic beauty of the room, and it will also exclude false positives and mechanical damage to parts of the system protection. So the installation of a protective device is recommended during the repair work. Wires are hidden in the joints of tiles or other material.

The installation technology of the system against depressurization and leakage is quite simple.

To install a leakage protection system, it is necessary to carry out a number of such actions:

install alarm sensors in the required places;
install a controlled valve;
connect the controller;
test the entire security system.

The installation of signal sensors occurs in two possible schemes installations: outdoor and indoor. Installation of sensors according to the second type is preferable.

The outdoor installation option has its pros and cons. The sensor is installed on the floor, electrodes down, if there is a breakthrough in the water supply system, water, when it gets under the sensor, starts the protective mechanism and the controller will turn off the valve. The imperfection of the method is that false positives occur, but the advantage is that it is possible to install a protective system even after installing plumbing and flooring. That is, to install protection, there is no need to violate the integrity of systems and objects.

The internal installation of the protective system implies the installation of sensors under the floor layer and the removal of electrodes to the outer surface of the floor. To prevent the protection from triggering when simply washing the floor, the electrodes are installed a few millimeters above the floor level.

Installation of the valve does not require any effort: just screw the nipple or branch pipe into the end of the installation valve. The joints are tightened with a locknut. Then the line is drawn junction box supplying the locking unit. The power consumption of the valve is very small: in idle mode it consumes about three watts, in working mode - about twelve watts.

Connecting the controller begins with the fact that the system case is attached to the wall surface near the shut-off motor. It can be carried to any convenient place. After that, wires are laid, which requires additional time, money and effort, so sensors that transmit radio signals are installed much faster than wired systems. The controller must be installed in a dry place, which does not allow water to enter the device or permanent moisture in the room. During the installation of the device, the electricity is turned off, following safety precautions will eliminate the risk of electric shock.

After this stage, the assembly stage of the device begins. If all assembly work successful, the message after the diagnosis will appear as a lit indicator. Green color will signal a job well done. The color of the indicator will change to red in the event of a leak. You can test this by dropping water on the sensor. The controller will operate and the valve will be closed. It will be possible to resume the water supply after pressing a special toggle switch on the controller panel.

Usage defense mechanisms is a 100% guarantee against development unusual situation.

The installation instructions give a detailed description of the process and the sequence of actions. Anyone can handle the installation process House master However, it is still better to entrust this task to a professional.

Types of water leakage protection systems

It is very important to take the issue of protecting homes from water leaks responsibly. After all, the consequence of the flood can be not only large material costs, but also a threat to human health and life. You can protect yourself from water leakage with the help of protective systems that reliably prevent the release a large number water. In this case, you do not have to worry about damaged flooring and furniture.

Stores offer various systems leakage protection from different manufacturers:

"Neptune";
"Hydroloc";
"stop-flood Rainbow";
"Aquastop";
"Aquaguard".

The structure of the protective complexes is completely identical. They consist of:

alarm sensors reporting an emergency;
taps that shut off pipes in case of a flood;
controller, which give a command about the lack of water.

Device for monitoring water leakage "Neptune"

For more than five years, the organization "Special Systems and Technologies" has been practicing in the production of protective systems. "Neptune" is the result of the work of this company. Among the main advantages of the protective system are the following:

technology safety;
reliability;
convenience of the device;
manufacturer's warranty.

Many protective devices operate at a voltage of two hundred and twenty volts. An electric shock of such strength is extremely dangerous for human health and life. In the event of an accident from a leak, a person comes into contact with water and an electric shock becomes even more dangerous. The company took this moment into account and the new manufactured mechanisms of protective devices against leaks work with a voltage of twelve volts.

"Neptune" is an extremely reliable protective system, as the flow of water in the pipes stops within twenty seconds. The system is equipped with an autonomous and uninterruptible power supply. This allows you to protect your home from water leaks even in the absence of electricity in the house. The program of the system includes monthly automatic self-cleaning of the ball valve. This allows you to clean the system of oxidation and limescale.

The system is very convenient, two sensors are included, although this is not enough to protect the apartment, additional elements should be purchased. About thirty sensors are needed for a medium-sized apartment. Installation in places of probable leaks will protect the room from the flood.

A manufacturer's warranty is given for the device that was purchased from an authorized representative for a period of three years.

A variety of protective systems "Neptune"

Protective systems are designed to identify and stop the consequences of inharmoniousness in water supply and heating systems. Changing the color of the indicator from green to red and a sound alert indicate an unusual situation. Neptune systems are represented by the following types of equipment:

"Neptune" Mini 2N;
"Neptune" BASE;
"Neptune" ProW.

1. Device for monitoring water leakage "Neptune" Mini 2N.

The device includes a standard set of a water leakage controller, a ball valve and a sensor that monitors leakage.

The functions performed by the device are as follows:

control of leaks in the system and water leakage;
automatic blocking of water inflow when the sensor reacts;
sound and light emergency notification;
the ability to perform tasks in the absence of voltage in the network.

"Neptune" Mini 2N is used in private homes, offices, shops, warehouses.

2. The device for monitoring water leakage "Neptune" BASE has a basic package: sensors (2 pieces), ball valve, controller.

The system performs the following functions:

controls the flow of water;
automatically blocks the water supply in case of an emergency;
produces light and sound notification;
performs automatic rotation of cranes on a monthly basis.

It is applied in private dwellings and public organizations.

3. The device for monitoring water leakage "Neptune" ProW is represented by a basic set of a controller, a ball valve and a sensor that controls water leakage.

Among the main functions performed by the protective system are:

water flow control;
automatic blocking of water supply in case of emergency operation of the sensor;
the ability to control and prevent leakage when the electricity is turned off;
targeting allows for indication in four directions;
notification with the help of sound messages and light notifications about an emergency;
automatic rotation of cranes once a month;
made for professional installation;
auto-closing of taps in case of voltage drop in an alternative power source.

Like other types of mechanisms that control emergency water leakage, they are used in private homes and public places.

The additional module has the function of sending SMS - emergency messages to the owner of the apartment, provided that the leak occurred during his absence.

Comparison of existing protection systems

There are many mechanisms from different manufacturers that serve as protection against depressurization of the water supply or heating system. But the most popular are the mechanisms of the following brand names: "Neptune", "Aquastorage", "Hydrolock".

A number of mechanisms of the brand name "Neptune" is represented by nine types of protection systems: five wired and four wireless devices.

"Hydrolock" and "Aquastorage" have a similar principle of control. Each of the systems is a reliable device and performs the functions of shutting off the water source and notifying of an emergency.

As practice shows, it is more expedient to purchase high-quality and reliable equipment for protection against emergency depressurization of water supply and heating systems than to go through extremely unpleasant moments later on resolving conflicts with neighbors, spending large sums of money on repairing and restoring things damaged by water.

If you still have questions about the principles of operation of protective systems against water leakage, about the rules for installation and operation, watch the video, which answers all questions that arise and describes in detail the main nuances of the mechanism.

Have you had the unpleasant experience of a water pipe burst? Do you want to protect yourself from possible damage to property and from conflicts with neighbors caused by the flood? Then you need reliable leak protection.

It is known that in big cities 9 out of 10 major utility accidents occur precisely in the water supply. And every day there are about 30-40 such problems in the water supply system, which is quite a lot even for a million-plus city. In most cases, special water leakage sensors help to save the situation, which are triggered if liquid gets on the floor.

Important: the system does not respond to simple wet cleaning in the room. The reaction of the system against leaks occurs at the moment when a sufficient amount of water touches the surface of the sensors.

In order to understand exactly how this works, it is necessary to have an idea of how the leak protection system works. A special smart device consists of several elements:

Electromagnetic (solenoid) valves for installation on a pipe.
Sensors (alarm devices) of contact with water (wire/wireless).
The control panel for the leakage protection system, which is also called the controller. It is a kind of control panel that can not only receive sensor readings, but also generate light and sound signals.

The principle of operation of the home "protector" is as follows:

First you need to install solenoid valves on the pipe after the coarse filter. In this case, it is desirable that the control part of such valves is located exclusively on top of the pipeline.

Important: some private craftsmen neglect the installation conditions of the system and install valves instead of a valve. This is absolutely impossible to do. Otherwise, there is a risk of leaving the entire riser without water in the event of an accident.

Water leakage sensor Mounted either on the floor or buried in the floor using silicone sealant. It is worth noting here that professionally installed control alarms should respond to a certain amount of water on the floor, and not to a simple floor cleaning.
So, when a large volume of liquid hits the floor, the sensors are triggered by the closure of the contact plates and send a signal to the control panel. This, in turn, gives a signal to turn off the water in the system. solenoid valves. The water is blocked until the arrival of the owners of the apartment. And now, in principle, an accident appears before you, but not on such a scale as it could be if the water poured incessantly.

Example: the included washing machine works independently without the presence of the owners in the house. In the absence of the owner of the apartment breaks drain hose, and water does not enter the sewer, but on the floor. Moreover, the washing assistant continues the cycle. And this means that about 90 liters of water will pour out onto the floor (this is how much the average machine takes for one wash). So, if the house has a water leakage protection system, then the sensors will block the access of water to the machine and it will stop its work. As a result, the accident will be eliminated in the bud. The owners will only have to collect spilled water and restart the car after repair. But if there is no protection against leakage, the water will flow smoothly until the caring hand of a person blocks it.

Important: if the house has several floors and each of them has a water supply system, then leakage protection must be installed on each floor.

It is worth remembering that reliable performance protection against water leakage in the apartment requires preventive care. So, once every 3-4 months, it is necessary to clean the contacts of the sensors from dust, grease and soot, so that the control signaling devices always fully respond to water. Cleaning is carried out using a soft cloth dipped in a light solvent. In addition, you should always monitor the condition of the mesh in the coarse filter housing. It must always be cleaned of accumulated sand and rye from the water supply.

Water leakage protection: types

All leakage protection for an apartment and office can be divided into wired and wireless. That is, the sensors of the system can be connected to the controller, or they can contact it remotely. Let's take a closer look at both types.

Wired elements. This type of control signaling devices is considered more reliable, however, it is not always convenient for installation in hard-to-reach places. Data transmission from such sensors to the controller occurs via wires. However, this e is a minus - it is not always possible to hide the wiring on the floor in the room. And it ruins the interior. A wired sensor has a lower price than a wireless element. At the same time, such a control signaling device consumes only 8 V. It is recommended to install wired sensors in close proximity to the control panel.
Wireless sensors. These elements work with the help of radio waves. This is how they send signals to the controller. But, despite the wireless design, the elements still need a separate power supply. In addition, wireless sensors are many times more expensive. Installation of such elements can be carried out at any distance from the control panel and in any, even the most inaccessible place.

Important: all sensors must be installed only in possible places of water leakage in the apartment. As a rule, these are the bathroom, kitchen and the location of household appliances powered by water and installed in utility rooms.

Benefits of a smart system

The system has an uninterruptible power supply. Thus, the leakage protection is completely non-volatile and can work even if the lights are turned off at home. At the time of turning on the electricity in the apartment, the battery of the device constantly works in the "charging" mode.
Ball valves provide reliable protection against leakage at any time of the day or night.
All working nodes of the system consume from 5 to 12 V, which does not pose a threat to humans. In addition, current is supplied to the system periodically when the signal is turned on.
Self-cleaning of ball valves from salt and lime deposits occurs due to the periodic closing of the elements.
Saving family budget on the power consumption of the system. Only 5-12 V and then only at the moment of opening / closing the taps.
All metal elements of the device are made of anti-corrosion alloy, which increases the service life of the devices.

Mounting smart protection from leakage must be carried out strictly according to the following scheme:

Installation of the controller at the selected location;
Installation of shut-off ball valves (valves);
Installation of leakage protection sensors (alarms) on the intended zones and their connection to the control unit;
Connecting the electrical wires of ball valves (valves) to the power supply;
Testing the connected device.

Well-known manufacturers of water leakage protection

The modern market offers a lot of smart systems aimed at protecting an apartment or house from water leakage. Let's take a look at the more popular ones:

Aquaguard protection

The system has many advantages:

So, the uninterruptible power supply built into the controller controls not only the operation of the system, but also the level of battery charge.
Leakage protection "Aquastorage" is designed to work simultaneously with six taps.
Installation of the system does not require special skills.
The sensitivity of the sensors is subject to regulation.
The device is equipped with a modern Japanese electronics system.
In addition, the system can be mounted with the possibility of decorating wires in the wall.

Important: in addition, the device is equipped with systems for self-cleaning valves, temporary shutdown of control signaling devices and auto-wake up from sleep mode.

Neptune system

Ideal protection against leakage for an apartment. The device can be mounted on metal pipes, and on pipes made of plastic or polypropylene. Protection can simultaneously serve up to 8 ball valves (valves) with 20 sensors connected to the system. At the same time, the response time of the system in the event of a water leak is no more than 2 seconds. In addition, the system is mounted in a canopy, which simplifies its installation.

Hydrolock protection

This system is able to work in temperature regime from -20 to +60 degrees Celsius. Wherein Maximum temperature water, to which the sensors respond, is +60 degrees. The defense has two alternative sources power supply - batteries and a battery that consumes only 1.5 V when the taps are turned on. Shut-off valves (taps) in the Hydrolock system are equipped with a self-rotating function, which allows them to be cleaned of limescale.

System "Rainbow"

This system has more modest working dimensions, but it does an excellent job of receiving signals from sensors. The response time of the system is up to 10 seconds, which are allotted for filtering out a false signal when wet cleaning etc. The controller can simultaneously contact with 9 sensors located in all water supply places. At the same time, in open areas, the maximum location of the control signaling device from the controller can be 100 meters, and if the sensors are installed in the apartment panel house- 20 meters. The weight of the entire system with all accessories is about 500 g.

Important: even if you are confident in your plumbing abilities, still, trust the professionals to deal with an electrician. In this case, you will be provided with a guarantee from the installer for the operation of the controller and signaling devices.

Many happy owners of comfortable housing often forget about extremely unpleasant problems that tend to appear where they are not expected. We are talking about elementary leaks. Their appearance, most often, is associated with unpleasant proceedings with neighbors, damage to property and, accordingly, serious unplanned expenses. In addition, there is also the risk of defeat electric shock when moisture enters the electrical network. The only way The solution to all these problems is a well-installed water leakage sensor. Rather, a whole system assembled from these devices.

How does such a system work?

Modern industry produces two types of such sensors. These are wired devices that connect to the controller using a wire, and wireless devices that send a radio signal. Regardless of the type of device, they are equipped with two electrodes. If the sensor is immersed in water, its poles close and the device sends a signal to the controller. That, in turn, redirects it to the shutoff valves and immediately blocks the water supply. The whole procedure takes no more than 15 seconds.

The water leakage sensor is triggered when moisture enters it. The signal is transmitted to the controller, which shuts off the water supply. All operations take no more than 15 seconds

The water will be turned off until the emergency is corrected. After that, it is enough to perform a few simple operations and the device is ready for use. A properly connected and properly functioning system fully guarantees reliable protection against sudden water or heating leaks.

To save money, some craftsmen recommend assembling a water leakage sensor with their own hands. Unfortunately, this is practically impossible. The device itself is quite simple, but it is difficult to make it absolutely safe. homemade device threatens with electric shock to everyone who lives in the house.

What is included in a leak protection system?

There are many variations of housing protection systems from leaks. The most common are Neptune, Aquaguard and Gidrolock (you can see more details at the end of the article). The principles of their work are similar. They are designed to work with motorized ball valves with a diameter of 1”, ½” or ¾”. Devices can not only block water, but also give a light or sound signal. They are also easily compatible with smart home systems and can be integrated into them.

Any water leakage protection system includes a leakage sensor, a control device controller and an electric ball valve

Let's talk in more detail about one of these devices, the Neptune devices. They are available in different variations, but all are present:

Controller. Designed to process the signal coming from the sensors and supply control voltage to the ball valves with electric drive. In addition, the device is responsible for powering all sensors, as well as sound or light warning of an accident. The controller can be mounted in any place convenient for the user, with the exception of those where water can get on it. Available in various designs.
Water leakage sensor. When moisture gets in, the device sends a signal to the controller. Connects only to a safe power source, so if you accidentally touch the plates, it is safe for others. Installed in places where leaks are most likely: approx. washing machines, bathtubs, shower cabins, sinks, etc. The manufacturer usually recommends wiping the sensor plates with a damp sponge at least once every 3 months. This operation is carried out for prevention and in order to check the performance of the entire system.
Ball valve with electric drive. The unit is designed to block heating or water supply in case of leakage. The device reliably holds water until the accident is eliminated. The device is installed immediately after the inlet valves in the drawer. For its installation, it is best to involve a plumber, since the connection is made only power cable PVA 3x0.5 or its equivalent through a junction box.

The number of elements of the system may vary depending on the characteristics of the place of its installation.

Rules for competent installation

Before proceeding with the installation of the system, you must create detailed diagram placement of all its elements, on which it will be necessary to mark the location of each device. In accordance with it, it is checked once again whether the length of the connecting wires included in the kit is sufficient for installation, if they are provided for by the design of the devices. The actual installation is carried out in the following sequence:

We mark the areas for installing sensors, cranes and the controller.
According to the connection diagram, we lay the installation wires.
We cut ball valves.
Installing sensors.
We mount the controller.
We connect the system.

Let's take a closer look at the most important stages.

Stage #1 - tapping the ball valve

As already noted, the installation of an electric ball valve is best left to a specialist. The device is mounted after the manual valves at the inlet of the pipeline. It is strictly forbidden to install structures instead of cranes at the input.

Before the node, it is recommended to put filters on the pipeline that purify the water. So the devices will last longer. It is also necessary to provide them with uninterrupted power supply. In operating mode, the device consumes about 3 W, at the time of opening / closing the valve - about 12 W.

Stage #2 - sensor installation

The device can be installed in two ways:

Floor installation. This method is recommended by the manufacturer. It involves inserting the device into a tile or floor covering in areas where water is likely to accumulate in case of a possible leak. In this case, the contact plates of the sensor are brought to the floor surface so that they are raised to a height of about 3-4 mm. This setting eliminates false positives. The wire to the device is supplied in a special corrugated pipe.
Floor surface installation. In this case, the device is placed directly on the surface. floor covering contact plates down.

Installing a water leak sensor with your own hands is quite simple, especially if the second method is used.

Stage # 3 - controller installation

Power to the controller must be supplied from the power cabinet. Zero and phase are connected to the device according to the connection diagram. To install the device, you need to perform the following operations:

We are preparing a hole in the wall for mounting the controller box.
We drill recesses for power wires from the installation site to the power cabinet, to each sensor and to the ball valve.
We install the mounting box on the prepared place in the wall.
We prepare the device for installation. We remove its front cover by alternately pressing on the latches on the front of the device with a thin slotted screwdriver. We remove the frame and connect all the wires in accordance with the diagram. We install the prepared controller in the mounting box and fix it with at least two screws.
We collect the device. Carefully put the frame back in place. We impose the front cover and press on it until both latches work.

If the system is assembled correctly, after pressing the power button, it starts working. This is usually indicated by a glowing indicator on the controller. When there is a leak, the indication color changes from green to red, a buzzer sounds and the tap blocks the water supply.

To eliminate the emergency, the manual valves of the pipeline are closed and the power to the controller is turned off. Then the cause of the accident is eliminated. The leakage sensors are wiped dry, the controller is powered on and the water supply is opened.

Competently installed system protection against leaks reliably protects against all sorts of troubles associated with water leakage

Video reviews of the systems "Neptune" and "Aquastorage"

The leak protection system eliminates many problems and unnecessary costs. The cost of compensation for damage is incomparable with the cost of the device. It is best to entrust the installation of devices to specialists who will competently and quickly carry out the installation.

As practice shows, self-made structures do not always fulfill their functions, moreover, they are potentially dangerous. You should not save on the safety of your loved ones, it is best to purchase and install a certified reliable device.

Emergencies, when water fills the whole house, can happen to anyone. A special alarm system can prevent flooding. The sensor works to determine the problem and block the sources of water supply to an apartment or house.

Then it can happen in any house or apartment. The reasons may be a pipe break or a drain problem. In this case, not only plumbing and furniture in the house may suffer, but also the apartment on the floor below. A water leak sensor will help prevent an unpleasant situation.

Flood alarms work much more simply than other sensors. The system is fast enough, it will help not only to identify problems, but also to shut off the water. This option is good when the owners are away from home.

Reasons for the flood:

Leaking tub or sink drain
Broken water supply pipe;
Clogged drain, which leads to obstruction of the drain and overflow of water over the edge of the plumbing;
Pipe burst when liquid spurts like a fountain;
Breakage of heating pipes.

Problems with the heating system are especially dangerous when it comes to the central system. Water moves through pipes with high pressure and has a high heating temperature. Even when the owners are at home, it is very difficult to stop the hot flow.

In just a few minutes, a house can pour 5 cubic meters of hot liquid.

In this case, it will be necessary to urgently shut off the coolant supply. But, in order not to endanger your life, it is easier to install a flood sensor. He does not panic, unlike people, and regularly performs his duties.

One of the causes of a sudden flood may be water hammer in the pipeline. The reasons, consequences and methods of protection are described in the article:.

The principle of operation of the Anti-Flood system and its classification

The operation of the system lies in the difference between the electrical conductivity of water and air. In the design of any sensor there is a pair of electrodes. When liquid enters them, the resistance decreases and the circuit closes.

Information is decoded on the controller. Next, the controller signals the closing of the solenoid valve. It is installed at the entrance to the riser.

The closing period lasts from 2 to 30 seconds. This is affected by the type of system selected.

The inlet valve will be stopped in operation until the cause of the leak is found. After setting up the controller, the system will return to its original form. The stationary signaling device works autonomously. Only if there is a problem will you need to intervene in the system.

Classification of the "Antipot" system:

Over the number of electric cranes;
Behind the method of informing about the problem;
Behind the option of data exchange between the sensor and the controller.

Normally, the number of electric cranes is at least two. This is due to the installation of sensors for hot and cold water. But if desired, the number of taps can be increased.

Water leakage alarm circuit

Can be used different variants performance of the system from leaks. The most popular are Neptune, Aquawatch, Ardvino and Gidrolock. They work on the same principle. Devices are installed on ball mixers with an electric drive. The safety elements not only shut off the water, but also signal the user that there is a problem with sound or light. These mechanisms get along well with the "smart home" system.

Leak sensor circuit elements:

Controller;
Water leakage sensor;
Ball water faucet with electric drive.

The controller is used to decode the signal that comes from the sensors and the drive voltage. The element feeds the rest of the structure and signals a problem. The controller can be mounted anywhere. The main thing is that water does not get on the device.

The leakage sensor reacts to moisture and sends a signal to the controller. To connect it, only safe power sources are used so that there are no emergencies when the plates are accidentally touched. It is mounted in places of probable leaks: next to plumbing.

Operation of the sensor includes wiping the plates with a damp sponge once every three months. This is a preventive measure.

Ball valves are used to block the operation of a water supply or heating system. Protective measures will be carried out until the unpleasant situation is eliminated, when the outflow of fluid is ensured. The installation of the device takes place after the water valves. Installation should be carried out by professionals, as the connection requires the use of a special power cable.

Installing a flood sensor from the manufacturer

Collecting the protection system is not difficult. The control box is mounted on the wall. Then the batteries are mounted. If necessary, make a power supply.

Sensor locations:

Under the bath or shower;
Under the sink and toilet;
Under washing machines and dishwashers;
Behind the radiators
Immediately at the point of entry and installation of the counter.

Then the signal cable is laid. Next, connect the sensors to the controller. If the system is wireless, then the action is performed with each sensor.

The ball valve is installed at the hot and cold water. It is also provided at the inlet of each riser or at the outlet of the boiler, if the system is autonomous. connected to the control unit. Everyone is given their own number and program.

This completes the installation process. You can safely go on vacation without fear of flooding your neighbors. The system is quite reliable, there is no doubt about its effectiveness.

The nuances of the location of the water sensor on the floor

There are many options for using sensors. There are many tasks that a small device can handle. But the system itself is quite simple.

Purposes of using sensors:

Bathroom flood detection;
Leak prevention in basements where high level occurrence of groundwater;
Control of kitchen plumbing;
Installation in areas where there is a high risk of flooding of houses;
Elimination of problems with leakage of the heating system.

Installation of sensors takes place in the most dangerous places. These are corners under plumbing, batteries. But at the same time, accidental ingress of water on the device should be minimized. Otherwise, the signaling device will work constantly for no reason.

Small leaks at pipe joints can be repaired with special sealants. What are the sealants, and how to use them, you will learn from our material:.

Do-it-yourself water leakage sensor assembly

Thanks to a simple mechanism, you can build a wired sensor with your own hands. The leak detector consists of simple elements that can be at hand. You may have to buy something, but the cost of the device is still petty. It should be understood that a home-made system only signals problems, it cannot shut off the water.

Necessary materials for work:

3 V battery - CR1632 device is used;
Transistor BC816 or BC517 with NPN composite;
1-2 MΩ resistor;
Piezo emitter complete with generator;
Plastic bottle.

The assembly process includes step by step instructions. First you need to familiarize yourself with the design scheme. Next, the resistor is soldered to the piezo emitter. Then the transistor is connected. The circuit is connected to the batteries using blue electrical tape.

Such an aquaguard will only work if water gets on the hull. Therefore, the battery will last a long time.

To create the case, you will need a large bottle, from which the neck is cut off. The bottom is made on one side of the bottle, which is fixed with glue. You will need to make 2 holes to insert the housing. Holes for the piezo are also made in the lid. We screw the cap on the neck and check the performance of the system.

The water leakage sensor is reliable protection from a flood in the house. By turning it on and off, you can control its operation. The mechanism itself may differ depending on the manufacturer, but the main elements remain unchanged. Interestingly, a primitive sensor can be built on its own. For this, you do not need to have special knowledge and materials.

Leakage of water supply pipes is associated with damage to floors and furniture, proceedings with residents of the lower floors. This leads to unforeseen expenditure of money and time to repair the damage. There is also the possibility of electric shock when water enters the cavities of the wires. Installing flood protection will help to avoid such troubles. The system consists of sensors, a control unit and shut-off valves. It is easy to install and does not require special care.

Water leakage protection device

In houses, emergencies often occur due to the flow of the water supply system. Mainly in older structures.

A flood damages both walls and floors, as well as furniture. AT high-rise buildings there is a threat of flooding neighbors from below. According to statistics, the damage from such a nuisance is three times greater than from a possible theft.

Modern appliances usually come with a leak protection system. According to the degree of protection, equipment is conditionally divided into several types:

with full protection
without protection
with partial protection.

Partial water protection - prevents water from leaking outside inner surface technology. In the devices below there is a one-piece pallet with a float with a switch. If the container fills with liquid, the equipment shutdown is triggered.

Full protection against water leaks combines the presence of a pallet and the installation of a special inlet hose.

But not all equipment provides sufficient protection against flooding. Therefore, it is necessary to install special equipment that will save your money and nerves.

Actual use of the system in places where there is a greater risk of leakage. And the estimated repair costs are many times higher than its cost. For example:

in administrative buildings
at country cottages,

in public institutions
in large scale production
in hotels and hotels,
in boiler plants.

Leak protection systems prevent emergencies. Their design involves three nodes:

compact flood control elements,
emergency water flow switches,
control box.

At a critical moment, the water supply in the water supply and heating channel is automatically turned off.

Sensors are placed under possible leak points. For example, a bathroom, a washbasin, a battery and a washing machine.

If moisture gets on the sensor, an alarm goes through the cable. And electric drives urgently shut off the water. At this time, the leakage indicator on the control unit lights up and an audible signal is emitted.

The leak protection system is easy to install. Because it does not require special intervention in the water supply system. Its installation is carried out both before and after the repair of the premises.

Protection against water leakage "Neptune"

The Neptune water leakage control system has been proving its reliability for 10 years.

The taps of the HC series are made of stainless steel, which is designed for water temperatures up to 90 C. In standby mode, the power consumption of the devices is up to 3 watts. They work in 5 - 7 s after moisture hits the sensor. A number of models involve manual control.

ZONAFAR zone actuators are made of brass. Respond to an emergency situation within 10-20 s. They are not manually adjustable; when the power is turned off, they remain in the same position. Faucets withstand water up to 100 °C. And at the same time, they assume continuous operation 24/7.

Electromagnetic analogs of "DANFOSS" are distinguished by ultra-high-speed overlapping of water. Not even a second will pass emergency situation will be warned. The faucet body is made of brass. Designed for water temperatures up to 90°C. In standby mode, the device does not use electricity, but when activated, it consumes 5 watts.

The Neptune system uses two types of control sensors: wired and radio.

The usual mechanism is connected by a 3-meter cable to the controller.

It works when moisture gets on its plates, which changes the resistance on them. The small dimensions of the sensor (46x12 mm) make it possible to place it in any required place.

Remote sensors are used in the Neptun XP system. The alarm signal is transmitted by radio signal to the control module.

Depending on the number of options, Neptune controllers are divided into mini, standard and DIN models. Additional functionality includes connecting an additional alarm or integration with security systems or smart home.

The first two options are wall-mounted, the SKPV220V-DIN controller is placed in the power cabinet.

"Neptune" automatically turns off the water supply. After eliminating the cause of the breakdown, resume the water supply by switching the button on the controller.

Installing the Neptune system involves a series of sequential steps:

marking the location of the elements of the system,
laying the corresponding wires,
valve installation,
placement of sensors around the room,
installation of the control unit,
connection and system check.

The Neptune system will cost 350 - 400 USD.

"AQUASTOP" - protection against water leaks

"Aquastop" is a unique device developed jointly by Italian and Russian scientists. The use of the Aquastop system for dishwashers or household washing machines is relevant. It protects against flooding when a hose breaks, shutting off the water supply in a few seconds.

The equipment is used at water temperatures up to 95 °C. For its performance, a pressure in the water supply system of 2 atm is sufficient. Moreover, as usual, analogues require 4 - 5 atm. The maximum working pressure is 10 units.

The device is fixed between the water supply tap and the conductive hose. In this case, the direction of the water flow is observed. Mounting is carried out from internal to external thread.

When a hose breaks, the pressure drops. The Aquastop system, under water pressure, instantly closes the flow of water.

"Aquastop" does not require complex installation or connection to the mains. And does not affect the operation of the washing machine or dishwasher. Most Bosch appliances are initially equipped with the AquaStop system.

The body is made of durable nickel-plated brass. outer diameter and internal thread is ¾ inch.
