Abstract

Method of confirming the presence or absence of leaks in a liquid storage container (10), particularly in partially filled underground storage tanks, subjected to partial vacuum for the purpose of testing the tank (10) for the presence of a leak (18) in the area above the liquid using a hydrophone (41) or microphone (100) either positioned in or attached to the container (10) to detect the sound produced by the ingress of fluid into the container (10) as a result of the vacuum.
The ingress of fluid is confirmed by recording and observing the vacuum pump (38) on/off cycles, the on/off cycles for a leaking container being distinguishable from the on/off cycles for a non-leaking container.
