Ajax WaterStop Jeweller 1" (DN25) in Black

The Ajax WaterStop 1" (DN25) water shut-off valve automates the water supply shut-off to help minimise damage caused by leaks. It can operate automatically following a flood alarm or be controlled remotely through Ajax apps, making it a practical solution for homes, businesses and other premises where rapid action against water leaks is essential.

This model combines an electric actuator with a Bonomi DN25 (1") ball valve, suitable for hot and cold water pipes. It can work together with an Ajax flood detector, such as LeaksProtect, to automatically shut off the water when a leak is detected. WaterStop can also operate through scheduled scenarios or when the Ajax system is armed or disarmed. 

WaterStop operates as part of the Ajax Jeweller wireless system and requires a compatible Ajax hub. Installation and commissioning are particularly straightforward for professional installers: simply open the Ajax app, scan the QR code and add the device to the system. In addition to remote control from a smartphone, it features a physical button on the enclosure and a mechanical lever for local valve operation without using the app.

This is not a replacement part; it is designed for new installations or extensions of compatible Ajax systems. It operates using four pre-installed CR123A batteries, providing up to 3 years of battery life, and also supports an external power supply. Combined with an Ajax alarm hub, it provides remote monitoring, automation and convenient control of the property's water supply.

Practical applications of Ajax Water Shut-Off Valve 1" (DN25) in Black

Example 1. Protecting an industrial facility against failures in the fire protection system water tank:

In an industrial facility already equipped with an Ajax alarm system, recurring failures in the cistern controlling the filling of the fire protection system's water tank caused significant water leaks over weekends. As the premises remained closed, the problem often went unnoticed until Monday, by which time water had already reached the warehouse and office areas. Installing an Ajax flood detector together with WaterStop allows the system to detect the presence of water and automatically shut off the supply whenever another failure occurs. This prevents large amounts of water from being wasted, reduces cleaning costs and, importantly, helps protect stock, furniture and other materials stored at floor level from potential flood damage.

Example 2. Preventive water shut-off when leaving the property:

In a second home or property that remains unoccupied for certain periods, the installer can configure WaterStop to close the water supply automatically when the Ajax system is armed. This allows the Ajax automatic water shut-off valve to become part of the security routine without requiring the user to manually close the main water valve whenever the property is left unattended.
