Smart WiFi Water Valve, APP Remote Control, Compatible with Alexa and Google Assistant, iOS/Android Apps, for Kitchen Gas Shutoff Valve, Farm Irrigation

3.9 173 reviews · $33.99

The title sells it as a "Kitchen Gas Shutoff Valve," but the listing names no gas safety certification.

Why we'd skip it

  • "Kitchen Gas Shutoff Valve" is in the title, and no UL, CSA, or other gas-appliance certification appears in the listing.
  • The bullets tell you to confirm your valve type and size yourself before buying.
  • 3.9 stars, the lowest of the valve robots here.

Buyer's guide

Do I need a plumber?

Not for valve robots and actuators, which clamp onto your existing quarter-turn main valve. Inline valves and whole-home flow monitors like Moen Flo are installed into the pipe and usually need a plumber.

How does it know to shut off?

Pair it with leak sensors, or pick a flow monitor that spots unusual water use. When a sensor gets wet, the valve closes the main line in seconds.

Will it work with my valve?

Robots fit most quarter-turn ball valves, but not gate valves with round handles. Check your main valve and pipe size before ordering.
