WaterStop Jeweller

Remotely controlled water shutoff valve
WaterStop promptly halts water flow within 7 seconds at any facility equipped with an Ajax security system upon activation by LeaksProtect or another water leak detector. This device integrates a premium valve with a robust electric actuator. WaterStop's operation and status can be managed remotely from any location via the Internet using the Ajax application. Additionally, it allows for the creation of scenarios to schedule water shutoff at predetermined times or upon system arming.

The misconception that anti-flood systems are challenging to install has been dispelled. Ajax has streamlined the process, making it less costly, quicker, and cleaner for both clients and professionals. Thanks to sophisticated hardware and software engineering, we've introduced advanced features with considerable autonomy in a small package. Our compact Ajax water leak detectors are designed for difficult-to-access areas and require no disassembly of enclosures for installation—they simply rest on any horizontal surface. The shutoff valve integrates seamlessly with existing plumbing, and the actuator, requiring no wiring, accommodates tight spaces with four distinct installation orientations relative to the valve.

Combine your system with LeaksProtect
Combining the Ajax LeaksProtect and WaterStop devices is a smart way to enhance your water leak detection and prevention system.
The two devices together form an ideal autonomous system that automatically monitors leaks, and if something happens, it also automatically closes the valves, and you receive a notification about this on your phone. No worries!


Create your own use case
WaterStop, integrated into the Ajax ecosystem, utilizes scenarios to engage with automation devices and the MotionCam lineup's PhOD detectors. It rapidly shuts off water supply in response to any leak, from minor to severe. Concurrently, MotionCam (PhOD) transmits images to the Ajax application, pinpointing the leak's source and evaluating potential damage. Additionally, its automatic water supply control feature ensures water is turned off when not in use, providing a dependable fusion of security and automation akin to the precision of a Swiss watch.
