Abstract
A method for isolating a leak in a closed-volume liquid system comprises circulating a fluid through a plurality of isolatable zones and a non-isolatable zone in a closed-volume liquid system, detecting a leak in the closed-volume liquid system, isolating all of the isolatable zones from the non-isolatable zone, sequentially detecting if the leak is present in the non-isolatable zone and each of isolatable zones, and taking corrective action after the leak is detected.
