A leak detection system monitors water flow through pipelines and cuts off water if abnormal behavior is detected. Leak detection systems are usually installed at the point of entry into a home. Water leaks commonly occur due to water hammer, high pressure, corrosion or aging plumbing. Leak detection systems use sensors, listening devices or imaging to detect leaks in small individual or large distribution systems. Home leak detection systems involve installing sensors on pipes and valves connected to an app to monitor flow and detect irregularities.
