Abstract

The presently disclosed subject matter includes, inter alia, a method and a device for monitoring water flow. The monitored data is analyzed in order to diagnose the water flow and identify abnormal events which may indicate that a leak is occurring. If a suspected leak is identified, the water flow can be shut down. Water flow shutdown can be done automatically by automatically controlling an electric water valve on the main water line. Alternatively a warning can be sent to a user indicating that a suspected leak is occurring and advising to shut down the water immediately.
