Abstract

A leak detection and response system includes a valve assembly with a housing defining an internal passageway. The valve assembly includes an internal inlet port, an internal outlet port, a valve port assembly, an external inlet port, and an external outlet port each in fluid communication with the internal passageway. The valve assembly includes a first sensor port disposed either between the external outlet port and the internal inlet port, or between the external inlet port and the internal outlet port. The valve assembly includes a first leak sensor positioned in the first sensor port for generating a signal indicating a presence of water. The valve assembly includes a controller configured to receive the signal from the first leak sensor, and control the valve assembly to align the valve port assembly to block water flow from the external inlet port.
