Instant Peace of Mind: Remotely Control Your Water Supply
Introducing the AJAX WaterStop, a smart, wireless water shutoff valve designed to provide ultimate protection against water damage. This essential smart home device combines a high-quality brass valve with a powerful electric actuator, allowing you to shut off your water supply in just 5 seconds from anywhere in the world using the AJAX app. Whether you're at home or away, the WaterStop offers immediate control and monitoring, ensuring your property is safe from leaks and floods.
Automated Protection & Smart Scenarios
The WaterStop seamlessly integrates into the AJAX security ecosystem. It can automatically shut off the water when a LeaksProtect sensor or a third-party detector is triggered. Create intelligent automation scenarios through the app: shut off the water when you arm your security system, set a schedule for water flow, or prevent the valve from seizing with a weekly automated cycle. These customizable scenarios provide an unparalleled level of automated protection, tailored to your lifestyle.
Robust Engineering for Maximum Reliability
Engineered for durability, the WaterStop features a powerful electric actuator with up to 8.5 N·m of torque, capable of closing even a stuck valve without risk of damage. The device is compatible with both hot and cold water pipes and can operate for up to 3 years on its pre-installed batteries. For added flexibility, it can also be connected to an external 9-12 V⎓ power supply. Its proprietary Jeweller wireless technology ensures a secure, encrypted, and long-range connection to your AJAX hub up to 1,100 meters away in open space.
Simple Installation & Manual Override
The AJAX WaterStop is designed for straightforward installation without the need for complex tools or disassembling the enclosure. The electric actuator can be mounted in four possible positions, making it adaptable to tight spaces. In case of emergency or power loss, a manual lever and a control button on the actuator housing provide immediate, tool-free water shutoff.
