摘要: An improved method for detecting small leaks in underground pressurized piping systems is disclosed and claimed herein. In particular, the comprises steps of taking pressure measurements over identical time intervals from a product line at above pump discharge while running. Thereafter, absolute value difference between successive decays calculated compared to an acceptable value. Next, latest decay unacceptable values reflecting tightness line.
