Not a drop of problems
Ajax stops leaks before they cause damage — whether in a small apartment or a multi-story retail center. Leak detectors instantly respond to pooling water and trigger shutoff valves that automatically stop the water supply within 7 seconds. Users learn about the issue as it unfolds: Ajax apps deliver real-time notifications with the exact leak location and allow users to control the system from anywhere in the world.
Complete solution for preventing water damage
Ajax WaterStop Jeweller
Wireless shutoff valve with an electric actuator for remote water supply control. Available with three valve options: ½” (DN 15), ¾” (DN 20), or 1” (DN 25).
Built to stand out
Set-and-forget setup
All devices are compact, neat, and fully wireless. They require no tricky installation and fit easily even in tight spaces. Once set up, the system runs for years on batteries or external power1 with minimal maintenance.
Advanced response within the ecosystem
With Ajax, leak detection is just the starting point. The system can trigger automation scenarios to shut off the water supply, cut power, or perform other first-response actions. Visual verification from cameras or motion detectors helps assess the situation firsthand.
In-app monitoring and configuration
No need to check pipes on-site: essential water supply information is available in Ajax apps. Users can view device states, receive instant, detailed leak notifications, manage the water supply, and adjust settings — all from one interface, even away from the property.
Designed for any scale
From small residential spaces to large commercial projects, a single Ajax system covers it all. With robust radio coverage and support for up to 250 devices, it can protect every spot where leaks may occur.
Advanced automation for greater safety
As part of the Ajax ecosystem, devices interact through automation scenarios. These scenarios help stop a leak immediately after detection, before technicians arrive. Beyond responding to alarms, devices can run on schedules, respond to arming and disarming, and automate regular servicing. Working like clockwork, automation helps keep the property safe and simplifies routines.

Automatic water shutoff
Ajax WaterStop Jeweller automatically shuts off the water supply within 7 seconds after a leak is detected. It works with both LeaksProtect Jeweller and third-party detectors connected via an Ajax integration module.

Water supply synchronized with security modes
The water supply can be automatically shut off when the system is armed and restored once it is disarmed. This ensures protection while the facility is unoccupied and automates an otherwise tedious, repetitive task.

Scheduled water supply
Ajax WaterStop Jeweller can follow a defined schedule, turning the water supply on and off at set times. Align it with working hours or daily routines to use water only when needed, thus reducing the risk of leaks when no one is around.
Schedule

Preventive maintenance
To prevent sticking due to inactivity, Ajax WaterStop Jeweller can perform automatic servicing at set intervals — every 7, 30, or 90 days. During this process, the valve opens and closes automatically, with no actions required from users or maintenance teams.
