Leak Detection Techniques Definitions
Drop Test: This method involves shutting off the water supply and observing the pressure drop in the system. If the pressure drops significantly, it indicates the presence of a leak within the system.
Visual Inspection: A thorough examination of all accessible pipes, fixtures, and fittings is conducted to identify visible signs of leaks, such as wet spots, corrosion, or dripping water.
Acoustic Sounding (Listening Stick): This technique detects leaks on pressurized water pipes by using a listening stick. The engineer listens for noise vibrations caused by water escaping from the pipe to locate the leak within the water network.
Acoustic Sounding (Ground Mic): A ground microphone is used to detect leaks in underground pipes. The device amplifies the sound of water escaping from the pipe, enabling the engineer to accurately locate the leak by listening for distinct sounds on the ground surface.
Pipe Correlation: A leak noise correlator, an electronic device, is utilized to identify leaks on pressurized water pipes. Acoustic sound sensors are placed at multiple points along the pipe, and the data collected is processed through an algorithm to determine the time difference of noise traveling from the leak site, pinpointing its exact location.
