Read the user manual and reviews about Water Leak Protection System.

Water leakage protection systems are functional solutions that help prevent emergency situations in the water supply system, which often entail serious financial costs, litigation with neighbors. The most relevant is the use of such devices in an apartment of a multi-storey building, where there is a risk of flooding several floors at once.

Components

The protection complex consists of the following elements:

Controller (control unit);
Sensors;
Automatic shut-off valves.

The detectors are located in risk areas - under sinks, bathtubs, plumbing fixtures, electrical appliances that use water, such as washing machines and dishwashers. Upon receipt of a moisture ingress signal from the sensor, a signal is sent to the controller, which instructs the shut-off valve to stop the water supply.

Such equipment is not a luxury, and its price is fully justified by the potential consequences of even a small flood. You can regard leak protection systems as part of an advanced "smart home" complex, but at the same time, this is a reasonable necessity that should be in every apartment.

A rare apartment owner does not know how much misfortune the flooding of the apartment brings due to an open tap in the kitchen or in the bathroom, as well as water leaks in the water supply and heating systems. A flood in an apartment entails colossal material losses and unpleasant proceedings with neighbors living on the floor below. Walls of an apartment flooded with water can cause failure of hidden electrical wiring and electric shock. Developed and implemented mass production of flood protection kits will allow you to avoid and forget all the problems associated with it. Next, we will look at how water leakage protection works in an apartment, as well as provide an overview and comparison of the most popular systems today.

Principle of operation and constituent elements

The protection system kit consists of the following elements:

Control block.
Water leakage sensors.
Taps for automatic shutoff of the water supply in the water supply and heating system of the apartment.

Understanding how protection works is not difficult. Sensors are installed in places where leaks are most likely to occur. As a rule, they are installed under bathtubs and washbasins, washing machines and water heating appliances, as shown in the diagram below:

Upon contact with water, a signal is removed from them and fed to the control module (controller), which performs the functions of a dispatcher. Having received a signal about the presence of water in the controlled area of the leakage protection system, the controller sends a command to the electric drive of the ball valve or to the electromagnetic quick-closing valve, which emergency shut off the water in the water supply or heating system of the apartment.

Overview of modern flood protection systems

The possibility of arranging an apartment with flood protection is not a prospect for the distant future. This is one of the real steps that can be taken today towards the introduction of high technologies of the “smart home” system into your home. Today, the market is dominated by several complexes that protect the apartment from leaks. Ready-made kits of the following types are in deserved demand:

"Neptune"
Hydrolok
"Stop the flood "Rainbow"

Often, an ordinary consumer, faced with a choice of protection, finds himself in a difficult situation and simply does not know which one is best suited to ensure the safety of his apartment from leaks and prevent a flood. The analysis of the working technical capabilities and characteristics of the listed devices will make it possible to compare their advantages and disadvantages, on the basis of which to select the necessary protection device.

Neptune

A product of Russian development, which first appeared on the Russian market back in 2000. The Neptune brand, according to the Moscow Business Times, is the most popular water leakage control system on the Russian market. The company's product range has a solution for any budget - from an affordable kit costing less than 10,000 rubles to an ultra-modern one controlled by a smartphone. Neptune water leakage protection can be installed not only on water pipes, but also on heating and water heated towel rails, which also pose a risk of water leakage.

The product line includes ready-made kits for an apartment, as well as individual components, which will allow you to assemble a complete set specifically for your tasks. In addition, Neptune leakage sensors work not only on wires, but also via radio, which allows you to install protection against water leaks at facilities with completed repairs, where it is no longer possible to hide the wires.

The warranty for Neptune water leakage control systems is up to 6 years for all elements of the system.

It is worth noting that the Neptune water leakage protection has been equipped with world-famous Bugatti ball valves, which are made in Italy, for many years. The peculiarity of these taps, in addition to a strong brand in the world of plumbing, premium sealing materials, and electric motor power, is that the electric drive has manual emergency control, that is, the tap can be opened / closed without electricity.

To choose the right Neptune leak protection kit, there are three main points to consider:

Are the renovations completed at your facility? If the repair is just starting, then you can choose any Neptune kit, since all control modules support wired sensors. At the stage of repairing a room, they are usually used, since they are cheaper than wireless sensors and you don’t need to change batteries from time to time. Bugatti ProW+ WiFi
The diameter of the pipes for water supply, heating or a water heated towel rail. Ready kits Neptune are equipped with ball valves of a certain diameter. For example, the most common faucet size for an apartment is ½ inch. Check with your facility or with your craftsman.
The budget allocated for the purchase of the Neptune water leakage control system. The set of options that the consumer will receive depends on the budget.

Neptune Aquacontrol- the most affordable leakage protection system, since the cost is less than 10,000 rubles per set for an apartment (control module, two taps and two sensors). This kit is completed with the Neptun Base module - this is a very simple and reliable control module that will shut off the water in case of a leak and once a month will automatically turn the taps against souring.

Neptune Bugatti Base- it's excellent value for money. As in the previous set, a simple Base module is used, however, ball valves are already made in Italy by Bugatti with a large margin of safety. The Neptun Base module does not have a backup power supply - if this function is important to you, then pay attention to the modules of the ProW series.

Neptune Bugatti ProW is a kit with extended functionality that works on wired sensors. Additional features of the ProW module:

Protection of taps from souring (automatic turning of the tap 2 times a month).
Supply voltage on taps –12 V DC
Built-in backup power supply.
Targeting - the ability to indicate leaks in 4 lines.
The ability to connect warning systems, security systems and integration with a "smart home" (the presence of a low-current relay).
Ball valve status indication (open/closed).
Backup power status indication.
Possibility of opening and closing the ball valve manually (button on the module).

Neptune Bugatti ProW+ similar to the ProW module, but has the ability to work not only with wired, but also with radio sensors - this is an ideal choice for those who have already completed home renovations.

Neptune Bugatti ProW+ WiFi- This is the most modern and functional interesting control module. Here's what he can do:

Security system control via smartphone. To do this, just install a free application and synchronize your mobile phone.
Timely notification of an accident. In addition to the fact that the module emits sound and light notifications on the front panel, additional information about the occurrence of a leak is sent to the screen of your mobile phone. A very important function, especially if no one is at home at this time.
Monitoring of hot and cold water consumption. Now it is not at all necessary to manually take readings every month by opening the cabinet with counters, which is located in the bathroom or in the kitchen. It is enough to open the mobile application and view the readings in it. This is a very handy feature for those who rent an apartment.
Backup power supply of the protection system. Even if the power supply to the apartment or house is turned off for a long time (up to 36 hours), the Neptun ProW + Wi-Fi module will work. The developers have introduced batteries into the design, which will be the source of backup power. By the way, the application will notify you in advance of the need to replace these batteries.
Indication of the position of ball valves. You can not only remotely monitor the taps, but also, if desired, automatically control them (close and open). If, having gone on vacation, you forgot to play it safe and turn off the water, this can always be done through the application.
Function of automatic turning of cranes. It is a self-cleaning mode of ball valves, which prevents the "souring" of valves. Automatic rotation is carried out every 15 days.
The Neptun ProW+Wi-Fi control module can be connected to the Smart Home system and the security alarm system of a residential building. There is a special exit for this.

The table below compares the Neptune models.

Gidrolock

Products of the Russian company "Gidroresurs". If we compare it with the Neptune device, it can be noted that the principle of its operation is the same, the package includes water sensors, a controller and electric ball valves. The company has developed and put into production several models of leakage protection systems, the basic version of which is Gidroloсk Standard.

Additional options for Hydrolock water leakage protection models:

Gidrolock is equipped with three sensors, the technical capabilities of this water leakage protection device include the connection of 20 wired and up to 100 wireless sensors. Time of the emergency termination of water to 30 seconds. The manufacturer guarantees 10 thousand working cycles and a general guarantee of the protection complex for 3 years.

An overview of the Hydrolock kit is shown on the video:

Russian development from the Supersystem company. The principle of operation and equipment are the same as those of the two previous analogues. Thanks to the introduction of innovative materials into the design of taps, efforts to overcome friction are significantly reduced, emergency closing of taps when a leak is detected in the apartment occurs in 3 seconds with minimal power consumption.

Compared to other systems, "Aquastorage" operates at an operating voltage of only 5 volts. The degree of automation of the control system does not require human intervention. It is completed with four sensors, both wired and wireless options are available. 4 year manufacturer's warranty.

Overview of the "Aquaguard" kit:

Stop flood "Rainbow"

A characteristic feature of this protection system is that all sensors are wireless and operate in the mode of supplying radio signals, the power of which allows them to remain operational at a distance of 20 meters from the controller in an apartment building. The product set includes 1 solenoid valve, 4 sensors. The control unit is designed to connect 9 sensors.

Compared to protection systems, Aquastop is just a mechanical device developed by Russian and Italian specialists. Prevents flooding of the room with water in the event of a rupture in the filling hose of the washing machine. Installed in front of the hose with a threaded connection, as shown in the diagram below:

In the event of a leak in the hose and a decrease in pressure in the system, Aquastop will shut off the water in a matter of seconds, which will stop further leakage. The principle of operation of the aquastop is demonstrated in the video:

Comparison of the cost of kits

Finally, we bring to your attention a comparison of the cost of the provided apartment flood protection systems:

This is where our review ends. We hope that now it has become clear to you how protection against water leaks in an apartment works and which systems are popular today. Price comparison and video reviews give a clear understanding of which kit is better to choose in order to protect your home from flooding!

In-house engineering systems can cause unpleasant problems for both the owner of the dwelling and neighboring apartments. The water in the plumbing or heating system is under pressure. Any malfunction of plumbing fixtures, blockages in the sewerage system, carelessness of residents can lead to flooding of several apartments along the riser of a multi-storey building. An automatic water leakage protection system will help prevent flooding of an apartment or house in a timely manner. It can be one of the elements of the smart home control unit, where all systems are controlled automatically using special sensors, control and actuators.

How it works

The principle of operation of automatic leakage protection is as follows. When water gets on special sensors, the electrodes short circuit. The sensor sends a signal to the control controller, which sends a control command to the locking equipment. Electric ball valves shut off the water flowing through the intra-apartment highway. The total time from the beginning of the moment of flooding (water hitting the sensor) to the complete shutdown of the internal pipelines is up to 15 seconds. Some systems notify the owner of the dwelling about the leakage that has occurred.

Device

The protection system consists of three main components.

There are two types: wired and wireless, sending a signal via radio waves. The task of the sensors is to control the humidity of the floor, and to work in the presence of a large amount of moisture (water). The sensitivity of the sensors is such that they do not react and do not send signals to turn off the water supply when it slightly hits the sensor. From simple splashes when bathing or washing, the sensor will not work, there will be no constant false positives. Shutting off the water due to splashing while taking a shower will be at least an unpleasant moment.

With a real threat of flooding, the sensors will definitely work. The installation locations of the sensors are chosen in places where water is likely to accumulate. As a rule, these places are located at potential sources of water: toilet, under the sink, bathroom, next to the washing machine, pipelines. The sensors give a signal only after the electrodes are closed. They are available in both wired and wireless models. Each has its own advantages and disadvantages. To install a wireless sensor, there is no need to think about where and how to lay the wires. Batteries are responsible for the functioning, the charge of which must be monitored. If they are discharged, then at the time of leakage they will not work. The reliability of wired sensors for these parameters is higher.

Controller

This is an automatic control system that receives signals from sensors, processes them and sends commands to actuators (electrically driven locking equipment). The task of the control unit is to collect information, make timely decisions and quickly issue commands to turn off the water. The blocks can receive and process signals from several sensors, as well as control several solenoid valves.

It is a ball valve, which is driven by a solenoid valve. The task of the tap is to shut off the water when a signal is given from the controller. The system has at least two valves that are installed after the shut-off valves for the intra-apartment distribution of hot and cold water supply pipelines. The system can be equipped with a large number of sensors, if it is necessary to control several risers, as well as the heating system. The design of shut-off valves with an electric or electromagnetic drive may be different.

System installation

Read the installation and operating instructions carefully before installing the leak protection system. The layout of all elements must be designed in detail, taking into account the characteristics of the room in which it will be installed and the pipelines. The placement of the elements should be at a distance from each other, depending on the length of the connecting wires available. If the length of the wires is not enough, then they must be increased. It is advisable to install the system during repairs in the room where all the elements will be located. The wires laid on top of the flooring will not look aesthetically pleasing, they can be subjected to mechanical stress up to a rush. Wires are recommended to be hidden between the seams of ceramic tiles.

Shut-off valves should be located immediately behind the shut-off valves that shut off the water from the intra-house risers.

Note! It is desirable to have a coarse filter in front of the solenoid valves.

Having marked the locations of the sensors, the controller, and the shut-off valves, wires are laid for all components of the system. Ball valves with an electric drive are cut in, sensors are installed, a controller is mounted. All elements of the system are connected and the performance is checked.

Sensors can be installed in two ways:

Floor installation. The sensor is supposed to be inserted into the floor covering. The contact plates should protrude 3–4 mm above the floor surface. This eliminates false positives. The wire is laid in a special protective corrugated pipe. This method is recommended by system manufacturers.
Floor surface mounting. It is used when it is impossible to install sensors in the floor. In this case, the sensors are turned over and laid with the plates down to shut off the water. The protrusions on the sensor body do not allow them to close when they touch the floor, which protects the system from false positives.

Any option for installing the sensor should allow it to be dismantled together with the wire, in case of its failure and prompt replacement.

The controller is installed in a dry, moisture-proof location. The power supply is hidden in the wall. Holes are drilled at the location for mounting the cabinet to accommodate the controller. After mounting the box, we connect all the wires to the controller, according to the diagram, and install it in the box. When connecting the control unit, do not forget about safety precautions and turn off the power supply to the wires leading to the controller. After connecting all the elements, we check the operation of the system.

System Comparison

In the domestic market, water leakage systems are represented by Russian and foreign manufacturers, with the leading positions of the brands Neptun, Akvastor, Gidrolock.

Systems "Neptun" from the company "Special Systems and Technologies" allow solving the problems of protection against leaks for one room, residential buildings, office buildings. The kit includes an electronic control unit, sensors with special contact plates and motorized ball valves. Neptune systems can be supplied with wireless sensors. The water supply stop time is 5-7 seconds from the moment the sensor is triggered, after which there is an audible and alarm notification of an accident. An additional GSM module allows you to send SMS messages to the homeowner if an accident occurs in his absence.

Note! The systems have a number of additional service functions: monthly automatic rotation of ball valves to prevent souring, recognition of a loss of communication with sensors, the availability of an uninterruptible power supply in the event of a power outage.

The line of models allows you to choose 5 wired and 4 wireless control modules, with wired and wireless sensors. The total number of connected sensors is 10.

"Gidrolock" are produced by the company "Gidroresurs". The line is represented by 4 models. The kit includes ball valves made of stainless steel with a Teflon seal and an electric drive, sensors with a wire length of 3 m, which can be extended up to 100 m. Anti-souring protection provides preventive closing and opening of taps every week.

"Aquaguard" has an identical principle of operation. Completely autonomous system, works only from replaceable batteries. On the basis of a single controller, you can choose 4 wired options and 3 wireless.

Video

Watch the video about the "Aquastorage Expert" anti-leakage system:

Although heating and water supply systems bring great convenience to all of us, they can also cause accidents. So, thousands of water leaks are recorded every day, which happen for various reasons: carelessness of people, breakdowns in communications, deterioration of pipes and plumbing, poor-quality installation, etc. Whatever the reason, the consequence always remains the same - flooding not only your apartment, but also neighboring ones, and repairs then flies into a tidy sum. According to the law of meanness, at the moment when a leak occurs, people are often not at home, and therefore it is not possible to quickly eliminate it. Everything would be much more convenient if you could know exactly when a leak occurs and instantly shut off the entire water supply system at home. In the modern world, this is no longer a dream, but a reality.

In order to ensure that flooding does not occur, a water leakage control system can be installed. Its sensors instantly react to the presence of water on the floor and give a signal to shut off the water. At the same moment, the apartment owners receive a signal about what happened, and only then they can call any plumber in Kyiv or another city to eliminate the cause of the breakdown and eliminate the most minimal consequences.

But, unfortunately, the choice of such a system is not the easiest task, since on the modern market there are options with not very sensitive sensors, devices that are not protected from interference, etc. Therefore, today we will turn our attention to How to choose the right leak detection system to be completely sure of your safety.

Criterias of choice

Modern leak control system comprises sensors that are placed on the floor, a control unit that responds to the sensor readings and gives signals to the solenoid valve, and in which case it shuts off the water supply to the apartment. In parallel with this, there is an alert by SMS, e-mail, in the form of a call to the owners.

Solenoid valves

Solenoid valves cut into the water supply: pay attention to the need to install a water filter in the place where the water will pass through the valve - this will ensure that it will work smoothly and close when it is needed. Experts also recommend not to mount valves in place of a manual valve, so that you do not have to turn off the water supply to the entire riser later.

Sensors

A very important component of the whole system - the sensors themselves which are installed on the floor or mounted in it. Normally working sensors will not respond to water drops or wet cleaning, unlike many low-quality products. When the water level on the floor is fixed by the system as critical, the sensors transmit a signal to the valve, which shuts off the water. The ideal voltage for working with valves is 12 V, but the usual 220 V will also work.

Supply system

Can't do without power supply, so try to keep it in a prominent place so that it is always easy and quick to monitor the health of the system. In order for the system to work clearly, do not forget to take care of it: you need to clean the sensor contacts from dirt, dirt and grease deposits at least once a quarter and eliminate blockages in the filters located in front of the valve.

To date, water leakage control systems from companies such as Aquastorg, Neptun and Gidrolock have proven themselves very well. Therefore, if you do not want to deal with the pros and cons of all existing solutions for a long time, but want to purchase the most reliable and durable system, then pay attention to the listed manufacturers.

Company "Neptune" has been operating in this market for almost 15 years. During this time, she managed to accumulate considerable experience and can provide several interesting solutions to choose from. So, the company offers the possibility of installing a wireless controller, which is much more convenient than wired counterparts. Sensors are installed directly in those places where there is the greatest risk of leakage: under the sink, bathtub, etc. After the signals from the sensors, the water supply is shut off for 5 seconds, and after the cause of the breakdown is eliminated, it will be possible to return the water to the house by pressing one button. Also, all systems of the company are equipped with a special valve souring prevention system: once a month it automatically closes and opens, and you can set the time yourself. The controllers operate on voltages of 12 V and 220 V and are equipped with an uninterruptible power supply. The system can be used both in residential premises and in office buildings.

Leakage control systems from "Gidrolock" are characterized by similar functionality, but here they approach the prevention of valve contamination even more carefully. So, every week a command is given to quickly close and open the valve or turn it a few degrees: as a result, this does not affect the comfort of the residents, and the system cleans itself. All parts are made of high quality materials, so they can withstand more than 100,000 opening / closing cycles.

But the systems from Aquaguard boast the longest warranty - as much as three years, an original approach to the power system, so that all leak control elements will function for a long time.

You can never exclude the possibility of an emergency caused by flooding of the premises. The damage from a water leak can be quite significant, especially when the incident occurs in an apartment building. In such cases, the consequences of the flood are often felt by the neighbors below, which only adds to the problems. To avoid such a development of events, it is necessary to install a modern control system that implements reliable protection against water leaks in the apartment.

What can cause leaks?

To prevent a "flood" it is necessary to establish the nature of probable leaks. Consider the three most common causes of leaks:

The influence of the human factor, for example, the overflow of the bath due to the fact that the landlord forgot to turn off the water supply.
Depreciation of engineering networks of water supply systems and sanitary equipment. High-rise buildings built in the 70s - 80s of the last century make up the bulk of the housing stock. The pipes installed in the risers of such houses have long exceeded the allowable service life, or are quite close to it. During pre-sale repairs, such nuances are often not paid attention to, replacing only internal communications.
Insufficient quality of plumbing equipment (pipes, faucet fittings, etc.) or installation work. Savings on repairing an apartment, in particular when installing hot and cold water supply, can later cause an accident, in which the neighbors will also be flooded. As a result, you will have to invest again in repairs and purchase new household appliances.

Please note that only the reasons associated with the water supply system are listed above. In addition, sewer leaks are possible due to wear or clogging of pipes, as well as breakdown of plumbing equipment.

The principle of operation of water protection

To clearly explain how the protection works, we will give an example of its typical installation.

Figure 1. Typical installation of the main elements of the leakage protection system

Designations:

Controller (the main element of protection against leakage).
Ball valves equipped with an electric drive (automatically shut off the water when a signal is given or the supply voltage is turned on).
Wireless .
Wired sensors.

The system operation algorithm is as follows:

The controller (a) polls the status of the sensors (c and d) regularly.
As soon as water enters any of the sensors, its characteristics change. Please note that the detectors that monitor the leakage of water should be located at floor level.
The controller immediately detects the change in the signal and sends a command to close the ball valves (b).
Electric actuators actuate the shut-off valve mechanism to shut off the water supply.

As a rule, such protection devices are additionally supplied with autonomous power sources so as not to lose their functions, even if there is no voltage in the household power supply.

Most devices, after one of the sensors has worked, give a sound and light signal, indicating that it is necessary to eliminate the accident.

After eliminating the cause of the accident, the ball valves are transferred to the working position, this is done manually or by giving a signal from the protection controller (depending on the design features of the shutoff valves).

Composition and layout of a typical protection system

As can be seen from the above principle of operation of protection against water leaks, such a protection complex includes the following basic elements:

The electronic control unit is responsible for the functioning of the complex (and in Fig. 1).
Sensors that detect leakage and send a signal to the controller (c and d).
Electric shut-off valve, it shuts off the water supply at the command of the control unit (b).

As an example, let's take a simplified Gidrolock protection electrical circuit.

Figure 2. Simplified version of a typical scheme of protective systems

Designations:

Connection to .
Fuse on the power supply of the protection controller.
The housing of the electronic controller, as a rule, is a sealed structure that does not allow water to enter inside. The material used is plastic or other insulating material.
Shutoff valve body with electric drive.
Connecting the drive housing to the ground bus.
Electric drive windings.
Residual current device, installed on the power line of the system.
Transformer providing galvanic isolation for power supply.
Keys for controlling the electric drive of shut-off valves.

Electrical safety systems

We draw attention to such an important criterion as electrical safety standards, an example of their implementation is shown in a typical electrical circuit shown above in Figure 2. First of all, this is the connection to protective ground of the main elements of the system, the installation of an RCD on the power line and the provision of galvanic isolation. In cases where the type of power supply is only autonomous, such security measures are not necessary.

As for the valve actuators, they are energized only in the event of an accident, when it is necessary to turn off the taps to turn off the supply of hot and cold water. The rest of the time, the electric drives of the ball valves are de-energized. On sensors (both in wired and wireless versions), the voltage does not add 5 volts, which does not pose a threat at all. Accordingly, even the metal case of the sensor does not need to be grounded.

Overview and comparison of popular flood protection devices

Here is a brief overview of systems that automatically shut off water to prevent leakage. The selection criterion was based on the popularity of devices on the Russian market. To assist with system selection, the specifications of the various models will be reviewed and a comparison table will be provided.

Aquastop

This device is a safety valve that shuts off the water supply in the event of a leak. The principle of operation of this completely mechanical device is based on the comparison of inlet and outlet pressure. A sharp difference between them (a characteristic sign of leakage) leads to the operation of a mechanism that shuts off the water supply through the leakage protection valve.

These devices are designed to be installed on water supply hoses to a mixer, washing machine or boiler. Despite the simplicity of the solution, one cannot fail to recognize the effectiveness and unconditional advantages of a protective valve, which include:

High response rate when a leak is detected.
Independence from the power supply.
Low cost compared to other protection systems.

In fact, Aquastop valves do not belong to the controllers under consideration, since they provide protection only for a local area and do not have the ability to connect to a common controller, which significantly limits functionality. Nevertheless, such a device is an effective means of flood prevention (by flooding an apartment), which has an affordable cost, which deserves to be mentioned in a general review.

Stop flood "Rainbow"

This leakage protection complex is a completely domestic development, in which the classical scheme of the principle of operation is used. The basic equipment of budget models includes a control unit, two wired sensors, one shut-off valve solenoid valve and installation instructions.

In top models, the system is controlled by an electronic controller capable of processing signals from 15 wireless sensors. Complete shutoff of water at the entrance to the apartment is carried out by ball valves with servo drives. The cost of such models depends on the configuration. Estimated price of a basic leak protection complex (controller, two wireless sensors, two electric taps, a set of batteries) is about $280.

Aquaguard

Protection "Aquastorage" is produced in Russia by the domestic company "Supersystem" under the license of the German developer Germany Engineering. The principle of operation of the controller is built according to the classical scheme. Below is a basic set of protection "Aquastorage Expert" ТН35.

This model comes standard with:

Control unit with radio controller.
Three batteries (batteries), 1.5 V each.
Two wired sensors.
Two wireless sensors.
Power supply from a stationary network 220 V.
Two signal wires 2 m and 4 m long.
Two cranes of the electric crane ¾.

The cost of protection in the listed configuration is $300-$310.

hydrolock

The protection manufacturer is the domestic company Hydroresurs. The development is based on the classical principle of operation. The main feature of this protection complex is high variability, which allows you to choose the optimal configuration for a house or apartment. In particular, the basic set APARTMENT 1 ULTIMATE BUGATTI, which includes: a controller, three wired sensors, two electric shut-off valves and a battery. If necessary, Gidrolocks are equipped with additional blocks that expand functionality, for example, sending SMS messages in case of an accident.

The cost of the basic set, given as an example, is about $ 260, with the addition of options, the price can increase significantly.

Neptune

At the end of the review, let's look at another Russian development of leakage protection - Neptun (Neptun), created jointly with the Italian company Bugatti. The figure below shows the basic configuration of the Neptun Bugatti Base kit (controller, 2 SHEP and 3-wire detectors).

Leak protection Neptune even in the basic version has a wide potential for expansion by increasing the number of sensors and electric cranes (up to 20 and 6 pieces, respectively). Despite the fact that this brand has the longest response time (up to 20 seconds) among the systems under consideration, its popularity does not suffer from this due to its relatively low cost ($240 for the given kit) and a long warranty (the manufacturer gives 6 years).

Final comparison table

In conclusion, we present to your attention a comparative table compiled according to the characteristics of popular models of various brands.
