Escaping water can produce useful sound
Acoustic equipment helps compare signals at suitable points on or above pipework. The engineer looks for a pattern that makes sense with the supply route and conditions.
The surroundings influence the result
Traffic, pumps and ordinary water use can complicate listening. Pipe material, depth and pressure also affect how sound travels. Some faults simply produce little useful noise at the available points.
Keep the wider investigation in view
If sound evidence is weak, another appropriate method may help. Acoustic results can support a repair location, but should be interpreted with other observations before opening a driveway or floor.
