The Wireless Water Immersion Automatic Shut-Off Valve 3/4" is designed to protect water installations from damage caused by unexpected leaks. When the wireless sensor detects water, it sends a signal to the valve, which automatically shuts off the water supply and helps prevent further flooding.

The system is suitable for homes, offices, commercial premises and technical areas. It can be installed near washing machines, dishwashers, sinks, water filtration equipment and other locations where a leaking connection or appliance could cause water damage.

Automatic protection against water leaks

Water leaks are not always noticed immediately. A loose connection, damaged hose, faulty appliance or other installation problem can release water for a considerable amount of time before anyone discovers it.

The automatic shut-off system provides an additional level of protection. The wireless sensor is positioned in an area where leaking water is likely to collect. Once water reaches the sensor probes, the system detects the leak and sends a signal to the control valve to shut off the water supply.

By stopping the flow of water at an early stage, the system can significantly reduce the amount of water released and help protect floors, walls, furniture, equipment and other property from damage.

Key features

Automatic water shut-off – the valve closes the water supply when a leak is detected.
Wireless water sensor – no signal cable is required between the sensor and the valve.
Expandable sensor coverage – up to 5 wireless sensors can be connected to the system; 1 sensor is included.
3/4" connection – suitable for common domestic and commercial water installations.
Ceramic valve mechanism – designed for low operating torque and minimal restriction of water flow.
Built-in rechargeable lithium battery – provides backup operation if the external power supply is interrupted.
Low power consumption – energy-efficient operation helps reduce power requirements.
Water-resistant sensor construction – helps protect the sensor's internal electronics from moisture and corrosion.

Where can the system be installed?

The shut-off valve can be used as additional protection in many areas where water leakage may occur, including:

under kitchen sinks and washbasins,
next to washing machines and dishwashers,
near boilers and other water-connected equipment,
in utility and technical rooms,
near water filters and filtration systems,
next to reverse osmosis systems,
in offices and commercial premises,
in other areas with water supply connections.

For effective leak detection, the wireless sensor should be positioned at a low point close to the potential source of leakage, where water is most likely to collect first.

How does it work?

The system combines a 3/4" automatic shut-off valve with a wireless water immersion sensor.

Under normal conditions, the valve remains open and water flows through the installation as usual. If water reaches the sensor, electrical conductivity between the detection probes activates the alarm signal. The sensor communicates wirelessly with the valve control unit, which then closes the valve and stops the incoming water supply.

This automatic response is particularly useful when nobody is present to notice the leak immediately.

Designed for reliable everyday operation

The valve uses a ceramic-core mechanism that requires relatively little force to operate. This helps reduce energy consumption while maintaining reliable opening and closing of the water supply.

The control unit also includes a rechargeable lithium battery, allowing the valve to remain operational during temporary power interruptions.

The wireless sensor uses a replaceable battery and can be positioned independently from the valve, making it easier to protect the areas most exposed to potential leaks.

Main system components

The system includes the main elements required for automatic leak detection and water shut-off:

Control valve with protective cover
Electronic valve control board
Rechargeable lithium battery
Ceramic-core shut-off valve
Stainless steel sensor electrodes
Wireless flood sensor control unit
Replaceable sensor battery
Protective sensor housing

Additional protection for your water installation

An automatic shut-off valve cannot prevent a pipe, hose or connection from developing a leak, but it can greatly reduce the consequences by stopping the water supply soon after the leak is detected.

It is a practical safety solution for installations where even a relatively small leak could cause significant damage, especially around household appliances, filtration equipment and technical installations.

With wireless detection, automatic shut-off and the possibility of connecting multiple sensors, the system provides simple and effective additional protection against accidental water damage.
