WaterStop allows you to remotely shut off the water at a facility with an Ajax security system. The device combines a high-quality valve and a powerful electric actuator with a control unit connected to an Ajax hub via the Jeweller encrypted radio protocol. You can control WaterStop from anywhere in the world. Check the device status and change the valve position at any moment — all you need is an Internet connection and the Ajax app.
If LeaksProtect or a third-party water leak detector is triggered, WaterStop will automatically shut off the water in 5 seconds. At the same time, all Ajax users and the security company receive a notification about the alarm and scenario activation. In addition to the water leak alarm scenario, it is possible to set the water shut-off at a specific time or when the security system is armed.

  1. David Mitchell –

    I bought this WaterStop valve to prevent flooding in my apartment. It integrates perfectly with my existing Ajax system. The 5-second shutoff feature gives me real peace of mind when I’m away. Delivery from apsardze24.lv was super quick too. Highly recommended for smart home setups!

    David Mitchell –

Can I install the WaterStop actuator on my existing water valve?

No, the product comes with a specific Bonomi Industries 1/2" (DN15) valve included. The actuator is designed to mount exclusively on this valve, requiring plumbing installation.

Is this the official EU version compatible with local app updates?

Yes, this is the official European version. It is fully compatible with the standard Ajax Security System app and receives all manufacturer firmware updates.

Is the valve suitable for hot water supply pipes?

Yes, the included Bonomi valve is rated for both hot and cold water systems. It is safe to install on standard residential hot water lines.

What is the expected battery life for the Ajax WaterStop?

The device operates on 4 pre-installed CR123A batteries with a lifespan of up to 3 years. For high-usage scenarios, it also supports an optional 9-12V DC external power supply.

Will the water shut off automatically if a leak is detected?

Yes, you can configure scenarios in the Ajax app to automatically shut off the water within 5 seconds if a LeaksProtect sensor or a third-party leak detector triggers an alarm.

Does the Ajax WaterStop (52271) work without an Ajax Hub?

No, this device is not standalone. It communicates via the Jeweller radio protocol and requires an Ajax Hub to function and connect to the internet.

How can I manually shut off the water if the system loses power?

The unit features a physical button on the enclosure and a mechanical lever on the mount. This allows you to manually open or close the valve without electricity or an internet connection.

What happens if the device malfunctions after installation?

Apsardze24.lv provides a comprehensive 2-Year Warranty for all business and private clients. Our authorized service center is located in Riga, ensuring fast local support and replacements.
