This model connects via Wi-Fi and can be controlled remotely through the Smart Life app, allowing you to monitor water flow, temperature, and pressure in real time from anywhere. When a leak is detected, it sends alerts via SMS, phone calls, and app notifications, then automatically shuts off the water to prevent damage.

Buying Guide for the Best Automatic Water Shutoffs

Choosing the right automatic water shutoff system is crucial for protecting your home from water damage. These devices can detect leaks and automatically shut off the water supply to prevent flooding. When selecting an automatic water shutoff, consider the following key specifications to ensure you get the best fit for your needs.
Detection MethodThe detection method refers to how the device identifies leaks. Common methods include moisture sensors, flow sensors, and pressure sensors. Moisture sensors detect water presence, flow sensors monitor water flow rates, and pressure sensors detect changes in water pressure. Choose a detection method based on your specific needs: moisture sensors are great for detecting leaks in specific areas, flow sensors are ideal for monitoring overall water usage, and pressure sensors can identify leaks in the entire system.
ConnectivityConnectivity refers to how the device communicates with you and other smart home systems. Options include Wi-Fi, Bluetooth, and Z-Wave. Wi-Fi allows for remote monitoring and control via a smartphone app, Bluetooth is suitable for short-range control, and Z-Wave integrates well with other smart home devices. If you want to monitor and control the system remotely, opt for a Wi-Fi-enabled device. For integration with existing smart home systems, consider Z-Wave.
Power SourceThe power source of an automatic water shutoff can be battery-operated, plug-in, or hardwired. Battery-operated devices offer flexibility in installation but require regular battery changes. Plug-in devices need a nearby power outlet, while hardwired systems are more permanent and reliable but require professional installation. Choose a power source based on your installation preferences and the availability of power outlets near the installation site.
Valve SizeValve size refers to the diameter of the shutoff valve and should match the size of your home's main water line. Common sizes include 1/2 inch, 3/4 inch, and 1 inch. It's important to select a valve size that matches your plumbing to ensure proper installation and functionality. Check your home's main water line size before purchasing to ensure compatibility.
Installation TypeInstallation type can be DIY or professional. DIY systems are designed for easy installation by homeowners, often with step-by-step instructions. Professional installation may be required for more complex systems or if you prefer not to handle the installation yourself. Consider your comfort level with plumbing tasks and the complexity of the system when deciding on the installation type.
Smart Home IntegrationSmart home integration refers to the device's ability to connect with other smart home systems like Amazon Alexa, Google Home, or Apple HomeKit. This feature allows you to control the water shutoff system using voice commands and integrate it with other smart home routines. If you have a smart home ecosystem, choose a device that is compatible with your existing setup for seamless integration.
Alerts and NotificationsAlerts and notifications are how the device informs you of a leak or shutoff event. These can be sent via text message, email, or push notifications through a smartphone app. Having timely alerts is crucial for quick response to potential water damage. Choose a system that offers reliable and customizable alert options to ensure you are promptly informed of any issues.
