Ajax WaterStop 3/4″ (DN20) Jeweller – Black / White

WaterStop 3/4″ (DN20) Jeweller is a smart water shut-off valve designed to help protect residential and commercial properties against water damage. When integrated with the Ajax ecosystem, it can be used to automatically isolate the water supply when a leak is detected, while also allowing remote control through the Ajax app.

The device combines an electric actuator with a compatible 3/4″ (DN20) shut-off valve, making it suitable for domestic and commercial water lines, including heating circuits, utility supplies and other plumbing applications where reliable automatic isolation is required. Its Jeweller wireless communication provides reliable connectivity with a compatible Ajax hub, enabling rapid response to leak events and system automation scenarios.

WaterStop can be controlled manually, remotely or automatically as part of an Ajax leak protection system. When paired with Ajax LeaksProtect detectors, the system can detect water, notify users and automatically close the valve to help limit further water loss and potential property damage.
