Overview
A motorised valve that fits onto the main water supply. Pairs with NOA Leak Sensors to shut off water automatically when a leak is detected, and can be manually toggled from the NOA app when leaving the house.
Problem it solves
Detection alone doesn't stop water damage — someone still has to act. The Smart Water Valve closes the main line automatically the moment a paired Leak Sensor senses moisture.
Recommended installation area
On the main water supply line where accessible. Professional plumber installation recommended.
NOA app connection
Pairs to the NOA app during setup. Manual open / close controls are available in-app, with a physical override on the unit.
Hub requirement
No dedicated hub required. Uses your home Wi-Fi.
Warranty
24-month limited manufacturer warranty. Professional plumbing installation is required to maintain warranty coverage.
Supported alerts and automations
- Auto-close on paired leak sensor trigger
- 'Away mode' — auto-close the main line when the last device in the home goes idle
- Scheduled close (e.g., overnight or during holidays)
