A method for identifying a leak in a pressure system. The method includes receiving, from a pressure sensor, pressure data of a fluid contained in the pressure system, determining a slope and curvature of the pressure data, determining a ratio of the curvature to the slope of the pressure data, and monitoring the ratio over a period of time. The method also includes, as a result of a non-constant component of the ratio exceeding a predetermined threshold, generating an indication that a leak may be present in the pressure system, or as a result of the ratio including no non-constant component or a non-constant component below the predetermined threshold, generating an indication that no leak is present in the pressure system.
