The point to understand
Escaping pressurised water may produce useful sound through a pipe or surrounding ground. Equipment helps assess that sound at suitable locations.
Put it into practice
Route information and accessible fittings can make the test more useful. Traffic, other running services and pipe construction affect interpretation.
Keep the limits in view
A quiet reading does not rule out every leak. The investigation may need a different method when conditions do not support useful listening.
