Automatic water shutoff
Configure a scenario responding to a compatible leak detector.
Ajax WaterStop Jeweller
Remote water supply control and automated leak response
Remote water supply control and automated leak response
Control the water supply through the Ajax app or a configured automation scenario. Combined with a compatible leak detector, WaterStop can close the valve when a leak is detected and report the resulting state in the app.
Up to 7 seconds
Specified valve shutoff time; a clogged or stuck valve can take longer.
Three valve sizes
½ inch DN 15, ¾ inch DN 20, and 1 inch DN 25.
Manual control
Use the actuator button or the lever on the mounting platform.
Battery operation
Up to 3 years on pre-installed batteries, depending on use and settings.
Flexible mounting
Four actuator mounting positions and ISO 5211 mounting platform.
Respond to leaks automatically
LeaksProtect or another supported detector can trigger a configured scenario to close the water supply. The valve state and system notifications are available in Ajax apps.
CHM selects detector positions and tests the leak-to-valve scenario with the complete system.
Choose the size for the pipework
The range includes ½ inch (DN 15), ¾ inch (DN 20), and 1 inch (DN 25) versions with a RuB shutoff valve.
The correct valve, installation point, water conditions, and accessibility are checked before installation. The product is suitable for supported cold- and hot-water applications.
Water control for everyday routines
Use schedules or system events to control the water supply. A configured valve exercise scenario can help reduce the risk of valve sticking.
Manual control remains available from the actuator button and the mounting-platform lever when physical operation is required.
Installation and maintenance
The electric actuator attaches to the mounting platform and can be secured with the anti-sabotage locker. An optional external power supply can be used as specified in the documentation.
CHM coordinates the plumbing and Ajax configuration, checks the selected valve size, and tests manual and automated operation.
