leak detection for extremely small leak?

My construction project for a commercial currently has a small leak (losing 1/3 gallon of water in 7 minutes, according to leak detection company) in the fire sprinkler line. They determined that the leak is so small that using their leak noise correlator device wouldn’t be able to pin point it either. However, is there other methods/devices to detect the location of the leak? Wouldn’t want to rip out a whole section of parking lot pavement.. submitted by /u/Luxsens [link] [comments]
