Total Control Over Your Water Supply, Instantly.

Protect your property from the devastating effects of water damage with the AJAX WaterStop, a smart, wireless water shutoff valve. Integrated into your AJAX security system, the WaterStop gives you the power to shut off your water supply remotely from anywhere in the world using the Ajax app. In the event of a leak detected by an AJAX LeaksProtect sensor, the WaterStop can react automatically in as little as 5 seconds, minimizing potential damage and giving you ultimate peace of mind.

Key Features:

  • Rapid Emergency Shutoff: The powerful electric actuator can shut off the water flow in just 5-7 seconds, whether commanded manually or triggered by an automated scenario.
  • Powerful & Reliable: With a torque of up to 8.5 N·m, the WaterStop can turn even a stuck valve, ensuring reliable operation when you need it most.
  • Remote & Automated Control: Use the Ajax app to check the status and control the valve from anywhere. Create scenarios that automatically shut off the water when a LeaksProtect sensor or a third-party detector is triggered.
  • Long-Range & Secure Communication: Featuring Jeweller radio technology, the WaterStop maintains a secure, encrypted connection with the Ajax hub at a distance of up to 1,100 meters.
  • Long Battery Life: Operates for up to 3 years on its pre-installed batteries, ensuring continuous protection even during power outages.
  • Easy Installation: The electric actuator can be mounted onto the included high-quality RuB valve without any special tools, in one of four possible positions.
  • Manual Override: A built-in lever allows for manual water shutoff in emergencies, providing a failsafe option that doesn't require power or a hub connection.

Advanced Automation for Complete Protection

The true power of the WaterStop is realized when it's part of a comprehensive Ajax security system. Configure simple automation scenarios that link the WaterStop to one or more LeaksProtect sensors. The moment moisture is detected, a command is sent to the WaterStop to immediately cut off the water supply, preventing a minor leak from becoming a major disaster. The system keeps you informed with instant, informative notifications directly to your smartphone.

Great privacy option for townhome deck!
Color: White, Size: 6 Panel, Color: White, Size: 6 Panel
Deck privacy! I wanted a way to add some privacy to my second floor townhome deck. It’s been holding up well and doesn’t look junky! I used zip ties on one end so I can open and close it as I wish. Great solution to living in close quarters to your neighbors! I purchased the six panel and it’s a perfect size

Reliable product made with care
quality has been consistently excellent every single time. It’s reliable, tastes great, and you can tell it’s made with care. What really stands out is how it makes me feel afterward. Even after working a 12-hour overtime shift, I don’t feel as exhausted. It genuinely helps me keep my energy up. Highly recommend if you’re looking for something dependable and effective. I’ll definitely keep ordering.

Look nice.
These were really nice for canned oysters, way better than what we can get in the stores in our area. Perfect for milk based oyster soup! the ratio is one can of cream of mushroom, one can full of milk, one can of oysters. Add butter, salt, pepper, and bring to a boil.

Does the job
Tastes like boiled oysters, so it has that nailed down. I use it in my shrimp ramen noodles sometimes, sometimes I use it to flavor garnish dishes. Best price I could find, but apparently it is a specialty product.
