Tuya Smart Water Valve
This smart water valve is for the homeowner who wants to prevent costly water damage while away. Instead of just a security device, it's your first line of defense against leaks and floods.
The valve automatically closes on your schedule, so you can stop worrying about burst pipes during a winter vacation. It works with Alexa for voice commands, letting you shut off water hands-free if you suspect a problem. The durable copper construction handles home water pressure reliably, giving you peace of mind that your basement stays dry.
