Protection against water leakage "Neptune. Water leakage protection systems

At the moment is topical issue protection of the apartment from domestic floods. In the event of such local disasters, their consequences can be irreversible and bring some harm not only to the property located in the apartment, but also to the health of the people living there. How can flood protection be provided?

You can eliminate the likelihood of leaks if you use special systems that negate the likelihood of a flood. In the event of an emergency, they cut off the water supply in a city apartment. Therefore, using them in your home, you can forget about repairs damaged by water.

Types of protection systems

The market currently offers leakage protection systems from several manufacturers.

• "Neptune" - it is offered by the company "Special Engineering Systems".
• "Gidrolok" - this product is produced by the company "Gidroresurs".
• Aquaguard - it is a product of the Supersystem company.

Design

All devices listed above are three main elements:

Principle of operation

If we talk about the principle of operation of such installations, we note that it is quite simple: when water gets on the sensor, the device transmits a signal to the controller. And that, in turn, shuts off the taps and all the water supply in the apartment.

Now it is worth considering in more detail the main leakage protection systems for a number of parameters. Comparison of their capabilities will allow you to find out the features of their device and functioning.

This product is manufactured by Special Systems and Technologies. This company has been engaged in the production of such products since 2002. The company is located in the suburban city of Mytishchi.

System Security

The Neptun Base version of this system can operate stably with a 220 volt power supply. Such voltage is unsafe for human health. Electric shock can be received when an accident occurs when the owner comes into contact with water. However, the next version of this Neptun Prow protection unit is powered by a 12V supply. However, it also cannot be called absolutely safe, especially for people who use pacemakers.

Reliability

One of the indicators that determine the effectiveness of protecting the system from water leaks is the speed at which the taps are closed in the event of an accident. If we talk about this in relation to the model under consideration, then in the event of an accident, the taps overlap within 21 seconds. One of the elements of this model is a power source powered by 4 CR123 batteries. You can buy such batteries without any problems in any store.

Therefore, when it becomes necessary to replace the power source, the owner will not have any difficulties with this. In addition to an autonomous power supply, an uninterruptible power supply was integrated into the design by the manufacturer. Its presence allows the water leakage protection system to work even in cases where electricity is cut off in the apartment.

The controller software has a self-cleaning function. It is launched once a month. Thanks to it, the opening and closing of the ball valve is ensured. And this makes it possible to clean this element of the system from deposits, as a result of which souring is excluded.

System Convenience

This leak protection system comes with two sensors. It should be said right away that this amount is not enough to protect the apartment from floods. According to the manufacturer himself, in order to ensure absolute protection of the apartment from leaks, it is necessary to use 35 sensors when installing this design.

Each sensor must be purchased separately. Their minimum number to provide reliable protection against the flood is 20. They are installed in places of possible leaks. If the length of the cable from the sensors is not enough, then by calling a specialist, it can be increased. The standard wire length with a tap is 1 m.

Guarantee

If the Neptune version was purchased from an authorized dealer, then the owner of the apartment can count on a 3-year warranty.

Gidrolock anti-leakage system

This protective device is a product manufactured by Hydroresurs. The set includes ball actuators of various standard sizes.

Safety

During the operation of this leakage protection system, a voltage of 12V is applied to the ball actuator. When the Gidrolock is in normal operation, the battery is charged with a low current, which ensures long term services. When the power is turned off, the system continues to operate on battery power. As for the speed of closing the taps during a leak, it is rather slow. It takes up to 30 seconds to transfer valves to the closed state, depending on the model of valves.

Reliability

The Gidrolock anti-leakage system is equipped with motorized valves, which are made of stainless steel as a material. They withstand working pressure up to 64 atmospheres. Seals for such taps are made of polytetrafluoroethylene. In contact with a stainless steel ball, they practically do not wear out. More than 10 thousand opening/closing cycles make up the resource of a ball valve. If we talk about the temperature resistance of products, then they can withstand temperatures up to 220 degrees Celsius.

The Gidrolock system has a self-cleaning function. With prolonged use of the equipment, problems may arise due to the deposition of salt and dirt on the walls of the pipes. This can lead to souring of the equipment. Therefore, once every two weeks, a command is given from the main unit of the system to temporarily close / open the electric drive. The ball valve rotates 5 degrees to prevent souring.

Ease of use

This system comes with 3 sensors. Although this is more than that of the Neptune system, but in order to provide full protection apartments from leaks, this is not enough.

It is worth saying that you can connect to this system:

• up to 20 sensors;
• 20 ball valves with electric drive;
• up to 100 radio sensors;
• gsm alarm.

The standard kit includes sensors supplied with a 3 meter cable. If this length is not enough, then it can be increased to 100 m.

Guarantee

By purchasing this protection system from an authorized dealer, you can count on a 3-year warranty. The main condition for the warranty repair by the seller or replacement is the absence of mechanical damage to the equipment.

Aquaguard protection system

The company "Supersystem" is the manufacturer of this protective system. It has been produced since 2006. The kit includes faucets of various sizes.

Safety

The main difference between this protective system and the previous two is the safe voltage, which is only 5V. Such tension will not harm a person. In addition, the manufacturer took care of the chemical safety of the equipment. It consists of nickel-plated brass taps. They prevent the formation of impurities in the water that can become a threat to human health.

Reliability

In its composition, the manufacturer used an electric crane of his own design. The faucets use two Teflon gaskets and one silicone-based springy gasket. Due to their presence, minimal friction is created when using cranes, as a result, power losses in the gearbox are also minimal. Reliable operation of the cranes is ensured even with a 5V power supply. Overlapping of water occurs within 3 seconds.

The “Expert” variant of this system uses “smart cranes” technology. Its main advantage is that it analyzes and controls the open circuit of connected taps, as well as the occurrence of malfunctions and their souring. This makes it possible for the owner to control the performance of the system, which reduces the influence of the human factor to zero.

Convenience

The installation kit includes four sensors. A feature of this model, providing convenience in its use, is an easy possibility for modernization. Due to the connectivity of the modular chassis design, it is easy to convert from a wired version to a wireless version.

If desired, it can be easily integrated into the "smart home" system, and also connected to the GSM system. It is convenient to use it to connect pumping equipment, cranes, as well as other devices whose power varies from 2 to 4 kW.

Guarantee

4 years is the warranty provided by the manufacturer for this protective installation. The manufacturer provides a lifetime warranty for wired sensors. We also note that such a guarantee applies to all sensors of the Aquaguard system, regardless of where they were purchased.

Conclusion

Protecting your home from leaks important problem for many people. In order not to encounter damaged repairs or furniture due to the flood, care should be taken to install special systems. Thanks to them, the water will be blocked in the event of an emergency. Thus, it will be possible to avoid the flood and all the consequences associated with this disaster.

Available on the market several similar installations. For good choice before buying, you need to familiarize yourself with their advantages and features of operation. In this case, you can ensure reliable protection of your apartment from the flood and avoid unexpected expenses.

Today, there are many technologies that can protect your home from all sorts of troubles. One of them is the Aquastop system. Protection against water leakage is carried out by means of automation. Such a device is able to save the repair of both the owners of the apartment and their neighbors who live below. The device includes several elements, the installation of which can be done independently. Today, the consumer is presented with several systems of this type. User reviews will help you choose the best one. Protecting your home from a flood is quite simple. The use of "Aquastop" can save significant funds family budget.

general characteristics

Many manufacturers household appliances associated with plumbing, equip their products with built-in leakage protection. However, this applies only to top models, and from a flood due to a breakdown, for example, of a mixer, they will not be able to help in any way.

To protect yourself from trouble, it is necessary to provide protection globally, and not only from the side of a possible breakdown of the washing machine. Here it would be more correct to block the water supply to the apartment. This is the meaning of the smart Aquastop system. Protection against water leaks is carried out by it on a scale of the entire apartment. The elements included in its composition, due to their well-coordinated work, block the flow on the common line of its supply to the apartment. This guarantees one hundred percent prevention of damage to property from the water supply.

Equipment

There are 3 main elements that are included in the Aquastop system. Protection against water leaks (photo below) is carried out using electric ball valves, a controller and sensors for increasing humidity. If water gets on the floor, it is captured by the sensor.

Sensors can be located in the kitchen, in the bathroom. They can be tied to the same controller. It is the "brain" of the entire system. It processes the signal received from the sensors and closes the electric ball valves if necessary. The latter are mounted in pipes for cold and hot water supply. Sensors can be wired or wireless. Their number in the kit varies depending on the type of system. Whatever the equipment is in this device, you can mount it yourself.

Installation of ball valves

There is a certain technology that allows you to install the Aquastop system. Protection against water leaks, the installation of which is carried out on your own, will require studying the sequence of actions. Electric ball valves must be cut into the pipes behind the manual inlet valves. In no case should they be installed before or instead of shut-off valves.

Before installation, the water supply is shut off. Further, the wiring is disconnected from the inlet valve. Then the cranes of the system are installed. If the thread is external, it is simply wound on communications. When it is internal, you will have to use the "American". The thread is wrapped with a sealant (fum-tape, tow). The tap of the system is screwed to the valve in a certain direction. It is marked with an arrow. Pipes are connected.

Controller

The control device has the main requirement in the process of installing the Aquastop system - protection against water leaks. What kind of device is it, it is easy to understand by its appearance. Photo provided below.

This is digital equipment. That's why it doesn't like high humidity. Durability will ensure its installation in a dry, splash-proof place. Humidity should not exceed 70%. Having chosen a suitable place, it is necessary to fasten the plate to the wall with self-tapping screws. It is included in the kit. When this work is completed, you need to install the controller. It is mounted on a screwed plate.

Sensors

After carrying out the above manipulations, the next stage of the installation of the Aquastop device begins. Installation of a water leakage protection system now involves the installation of sensors.

With their wireless options, everything is simple. Such sensors are installed in places of probable leakage. But with wired varieties you have to tinker. The wires can be left open or hidden behind the plinth, between the seams. The sensor is usually fixed with adhesive tape or a screw to the floor. It is closed with a decorative cap.

Connection

When all elements of the system are located in their places, they must be connected to each other. The corresponding connectors of the controller (marked with inscriptions) are connected to the control device in the required terminals. Wireless devices are already registered in the controller's memory. You don't have to connect them.

The battery pack must be connected to the board. For this, it has a special connector. The block is connected to the main part of the controller. For this, the wires are pulled through a special hole. If the system is wireless, it is necessary to connect the battery pack to the radio base. Then they are attached to the controller. All work takes from 1 to 4 hours. By following the instructions, it will be quite easy.

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 flooring, or drown in the floor with the help 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 simple washing gender.
• 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. And the cycle washing assistant continues. 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 the reliable operation of protection against water leakage in the apartment requires preventive maintenance. 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, but 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 locations. household appliances operating from 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 the family budget on the consumption of electricity by 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.

Installation of smart leakage protection 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 smart systems designed to protect 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 modern Japanese system electronics.
• 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. At the same time, the maximum water temperature, 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, on open area 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.

Leak protection system

Surely everyone who has at least once encountered modern construction and finishing materials, I heard about such a concept as a leakage protection system or an anti-flood system, however, not many people know what it is and how it works.

Let's try to scare you first. Imagine the situation: dark dark night in dark dark room a small dark spot appeared on the ceiling, which began to increase in size, crawled onto the wall. You jump out of bed in horror, turn on the light, and - a pipe breaks. Water began to appear where it should not be: on the ceiling, expensive parquet, on the wife's favorite carpet and the dog's favorite sofa. In the event that you are at home and detect these leaks in a timely manner, you will get off minimal cost. What happens in your absence - think for yourself.

Now let's try to reassure: the carpets can be dried, the parquet can be shifted, the wife can be reassured, and your plumbing and heating system can be protected from such “wet” things in the future. Fortunately, there were such people who invented a miracle device called “leak protection system”.

How Anti-Flood Systems Work

If you "climb" inside, it turns out that most leakage protection systems consist of three main elements: leakage sensors, a control module and shutoff valves. The mechanism of operation is as follows: water leakage is detected by sensors located on the floor in the bathroom, kitchen or any other water-hazardous place where there are means of communication - pipes with hot and cold water, sewerage. These functional elements send a signal to the control module.

As a rule, this is a small unit that can be placed in any convenient place: with the help of this equipment, you can manually stop the water supply to the apartment or unlock the system if leakage has been prevented. After the control module receives a signal from the leakage sensors, work starts shut-off valves: water leakage is eliminated directly with the help of these elements, which cut off the water supply to the apartment, eliminating the threat of flooding and damage to property.

Leak sensors

The water leakage sensor generates a signal when water enters it and is designed to record an emergency. It connects to a safe power source and does not pose a danger when touching the contact plates. Usually it is a small sealed plastic (rarely metal) container, on one of the surfaces of which there is a simple sensitive element - two contacts with an anti-corrosion coating applied to them.

The principle of operation of the sensor is as follows. When the contacts are closed with a layer of any liquid that has electrical conductivity, for example, water (except for distilled water), the resistance between the contacts drops sharply, which is a signal of leakage. The sensors do not pay attention to small splashes falling on the floor, and only work if the contact plates are flooded. Water sensors are installed in places where water is most likely to accumulate in case of leaks (on the floor under the sink, bathtub, washing machine etc.).

If a wired system is installed, the sensors are connected to the controller with a shielded cable, which standard version has a length of 3-4 m, with the possibility of increasing it up to 100 m. A safe voltage of 5-24 V is supplied through the cable to the sensors. , which is enough for 1-2 years of continuous operation.

Advantages, as well as disadvantages, are inherent in both options - wired and wireless. The main advantage of wireless systems is their complete autonomy. Sensors can be located anywhere without being tied to the possibility of laying a cable, within a radius of 150 m (in line-of-sight conditions) from the controller. But this advantage turns into a minus - the controller, equipped only with a receiver, cannot automatically check the sensor's performance. Therefore, your hopes for the perfect operation of the leak protection system may not always come true. Some manufacturers, in particular LifeSOS, equip sensors with a battery monitoring function. A signal is sent to the controller, and if you didn’t replace the batteries on time, then with a critical charge, the sensor will give the command to turn off the water, despite the fact that you are standing in the shower.

Advantage of wired system just that the sensor is constantly energized, and the controller can always find out what state the sensor is in. by the most the best option are devices that provide two-way radio communication between the sensor and the controller, but this pleasure is offered mainly by expensive smart home systems.

Option 1

It is recommended to install sensors in the floor (cut into tiles, coating) in places where water is most likely to accumulate in case of leaks. Sensors are mounted in the floor with contact plates up. The wire is brought in a corrugated tube. The protrusion of the sensor above the floor line (3 - 4 mm) eliminates false alarms.

Option 2

If it is not possible to install the sensor into the floor, it is recommended to lay it on the floor with the contact plates down. In this case, the wire lies freely on the floor. Dot protrusions on the sensor housing prevent the contact plates from touching the floor, which prevents false triggering of the sensor. It is very important that the method of installation and fastening of the sensor allows dismantling the sensor with the cable in case of its failure.

Control block

The controller, also known as the control unit, is recommended to be installed in a place convenient for servicing and notifying the owners in the event of a water leak, and in the case of installing a wired system, close to the leakage sensors. The supply voltage to the controller and the solenoid valve must be supplied from the power cabinet and necessarily through the RCD (30 mA). The signal received from the leakage sensor is processed by the control unit and transmitted to the relay of the actuator. Do not install the controller in places where water can get on the case.

Executive devices

All types of devices that respond to an emergency can be divided into two groups - signaling devices and devices that block water. Signaling devices include devices capable of giving sound or light signals (sirens, buzzers, emergency lights, etc.) that warn of an emergency.

This also includes all kinds of devices for sending an external signal that use means of switching - a telephone modem or GSM - a module used to transmit data and SMS - messages in the GSM 900/1800 standard (it can be equipped with a built-in telephone or connected to mobile phone). Any of the two types of modems must be equipped with an uninterruptible power supply so that it can perform its functions if the mains voltage disappears. A list of telephone numbers is stored in the device's memory. For each of them, the type and content of the message (voice or SMS) is predetermined, which the device should send to this number if a leak is detected.

It should be understood that this is just a signal, and not a solution to problems. In order for the flood not to happen, only this device will not be enough, that's where taps and valves that can independently shut off the water come in handy. These are ball valves with electric drive and solenoid valves.

Electric ball valves

Electric ball valve is designed to block water supply and heating in case of water leakage. The ball valve is installed in the water cabinet immediately after the inlet valves. The remoteness of the ball valve from the controller is allowed - no more than 100 m. Ball valves do not independently resume the water supply either when the power is turned on or when the power is turned off, since they obey only the commands of the control unit.

The bodies of these devices are made of chrome-plated brass or stainless steel, and the faucet is capable of withstanding pressures up to 16 bar. The drive is a compact brushless electric motor equipped with a gearbox that reduces the opening / closing speed. The stabilized speed of the cranes at the start prevents possible water hammer. In the standby mode, the drive does not need energy, it is turned on only by a signal from the controller. At the time of closing (opening), taps, depending on the manufacturer, consume from 4 to 12 watts.

As well as leakage sensors, there are models of ball valves powered by a 220 V network or from a built-in power source. The latter are controlled via a radio channel (“Aquaguard”, “Neptune”), it is especially convenient to operate a crane that has the “manual control” option, which makes it possible to control the crane in the event of a power outage (“Neptune”). Some models of protection systems have useful feature"technical check". With prolonged inactivity, deposits of salts and dirt may appear on the surface of the working ball - the so-called souring occurs. To prevent this process, the control unit once a week gives the drive a command to rotate the ball by 3 - 5 °. Such a function is possessed by the protection systems "Aquastorage", "Neptune", Gidrolock.

Solenoid valves

You can also turn off the water using solenoid valves. Such devices are provided in LifeSOS, H20Kontakt, Axico systems. Solenoid valves consist of a damper (gate) and an electromagnet or solenoid.

There are two types of devices: normally open and normally closed. Normally open valves are held open by a locking device. When an energy pulse is applied from the control unit to the coil, the locking device is turned off and the water flow is blocked. Normally closed valves are kept open by the operation of a solenoid coil.

When there is a power outage or a leakage sensor is triggered, the valve closes, it can only be opened when power is supplied (everything is normal with power, and the sensor shows no leakage). Both valves have one significant inconvenience - they need electricity, so experts recommend using valves operating on 12 V voltage, and equipping the system with backup source nutrition. Solenoid valves are demanding on cleanliness. A filter must be installed between the inlet valve and the valve mechanical cleaning water.

And finally

Leak protection system is an affordable device for all homeowners. Moreover, there is different variants her acquisitions. You can buy a ready-made kit, which will include leakage sensors, a controller and one or two motorized ball valves. You can also purchase all of these items separately. The main thing is to carefully consider what should be included in this set. Thus, it is possible to prevent water flooding within three seconds after its detection: with the help of a protection device, any water leakage will be detected and eliminated immediately, and the owner of the apartment will quickly find out about what happened using a convenient notification system (by phone, SMS or via the Internet). ).

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:

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

Problems with the heating system are especially dangerous when it comes to central system. Water moves through pipes 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 closure 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

You can use different versions 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 valve 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:

1. Bathroom flood detection;
2. Leak prevention in basements where high level occurrence of groundwater;
3. Control of kitchen plumbing;
4. Installation in areas where there is a high risk of flooding of houses;
5. 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 simple mechanism you can build a wired sensor with your own hands. The leak detector consists of simple elements that may 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:

1. 3 V battery - CR1632 device is used;
2. Transistor BC816 or BC517 with NPN composite;
3. 1-2 MΩ resistor;
4. Piezo emitter complete with generator;
5. 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.
