Water leakage sensor: for leakage, do-it-yourself, floor flooding, for signaling device, anti-flood system, for taps

Accidents when water fills the whole house can happen to everyone. Prevent flooding can special alarm. The sensor works to detect problems and block sources of water supply to the apartment or house.

The need to install a water leakage sensor

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

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

Flood reasons:

1. Leaking bath or sink drain;
2. Torn water supply pipe;
3. Clogging of the drain, which leads to obstruction of the drain and overflow of water over the edge of the plumbing;
4. A pipe breakthrough when a liquid gushes forth a fountain;
5. Breakthrough 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, stopping the hot stream is very difficult.

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

In this case, you will urgently need to shut off the coolant supply. But in order not to endanger your life, it’s easier to install a flooding sensor. He does not panic, unlike people, and regularly performs his duties.

One of the reasons for a sudden flood can be a water hammer in the pipeline. The reasons, consequences and methods of protection are described in the article: https://homeli.ru/stroitelstvo-doma/inzhenernye-sistemy/kanalizatsiya/gidroudar-v-truboprovode.

The principle of operation of the Antipotop system and its classification

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

The information on the controller is decrypted. Further, the controller signals the closure of the solenoid valve. It is installed at the entrance to the riser.

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

The inlet valve will stop working until the cause of the leak is detected. After configuring the controller, the system will return to its original form. The stationary signaling device works autonomously. Only if there is a problem will it be necessary to intervene in the system.

Antipot system classification:

• For the number of electric cranes;
• For the method of reporting a problem;
• For 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 in hot and cold water. But if desired, the number of cranes can be increased.

Water Leak Signal Diagram

You can use different versions of the system from leaks. The most popular are Neptune, Aquastorozh, Ardvino and Gidrolock. They work for a similar principle. Devices are installed on ball mixers with an electric drive. Safety elements not only block water, but also signal the user about a problem with sound or light. These mechanisms get along well with the smart home system.

Leakage Sensor Circuit Elements:

• Controller;
• Water leakage sensor;
• Electric ball valve.

The controller is used to decrypt the signal that comes from the sensors and the voltage of the electric drive. The element feeds the remaining parts of the structure and gives a signal about the problem. Installation of the controller can be done anywhere. The main thing is that water does not get on the device.

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

The operation of the sensor involves wiping the plates with a wet sponge every three months. This is a preventative measure.

Ball valves are used to block the operation of the water supply or heating system. Protective measures will be carried out until the unpleasant situation is eliminated, when the outflow of liquid is ensured. Installation of the device occurs after water valves. Installation should be carried out by professionals, since the connection involves the use of a special power cable.

Leaks in the pipeline can occur due to poor connection of PVC pipes. About how to choose glue for PVC pipes and how to use it correctly, read the article: https://homeli.ru/stroitelstvo-doma/inzhenernye-sistemy/kanalizatsiya/klej-dlya-pvkh-trub.

Installing a flooding sensor from the manufacturer

Collecting a security system is not difficult. A control unit is mounted on the wall. Then the batteries are mounted. If necessary, make a power connection.

Sensor Locations:

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

Then perform the laying of the signal cable. 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 points of entry of 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. Servos connected to the control unit. For each, they assign their number and program.

Then we go on to configure the system. It provides for the correspondence of sensors and servos, alert settings, signaling method.

This completes the installation process. You can safely go on vacation, not being afraid to flood the neighbors. The system is quite reliable, there is no doubt in 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.

Purpose of using sensors:

1. Bath flooding detection;
2. Prevention of leaks in basements where there is a high level of groundwater occurrence;
3. Kitchen Plumbing Control
4. Installation in areas where there is a high risk of flooding of houses;
5. Troubleshoot leaking 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 alarm will be activated continuously for no reason.

Small leaks at pipe joints can be fixed with special sealants. What are sealants, and how to use them, you will learn from our material: https://homeli.ru/stroitelstvo-doma/inzhenernye-sistemy/kanalizatsiya/kak-zagermetizirovat.

Do-it-yourself water leakage sensor assembly

Thanks to a simple mechanism, you can build a wired sensor yourself. The leak detector consists of simple elements that can be at hand. Maybe you have to buy something, but the cost of the device is still petty. It should be understood that a home-made system only signals a problem, it will not be able to block 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 provides step-by-step instructions. First you need to familiarize yourself with the design diagram. Further, 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 aqua watchman will only work if water gets on the case. Therefore, the battery will last long enough.

To create a case, you need a large bottle, with 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 piece are also made in the lid. We wrap the lid on the neck and check the performance of the system.

The water leakage sensor is a reliable protection against the flood in the house. By turning on and off, you can control its operation. The mechanism itself may vary depending on the manufacturer, but the basic 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.
