Tracking down the source of a leak in water pipes can be a tricky business. Current techniques rely on acoustic sensing with microphones often used to identify noise resulting from pressurized water escaping the pipe. In plastic pipes in particular, that noise can fall away quickly, making leak detection difficult and time consuming. Researchers at the University of Sheffield claim to have developed a much more accurate system that locates leaks by sending a pressure wave along the pipe that sends back a signal if it passes any anomalies in the pipe’s surface.
