Sonic uses HD Ultrasonic technology to detect flow of water and identify appliances connected to the plumbing network. Inbuilt temperature sensor can alert you to a potential frozen or freezing pipe, helping prevent bursts from occurring in the first place. Thanks to an integrated pressure sensor, Sonic performs a scheduled pressure check on the plumbing system, alerting you to even the smallest of leaks. The user-configurable integrated smart shut-off valve can isolate the incoming water supply in seconds, containing a problem before it can get any worse.
