Zusammenfassung:	A water detection apparatus includes a continuity probe, a voltage source that provides a reference voltage, and a control circuit. The control circuit provides the reference voltage to the continuity probe, measures a feedback signal corresponding to the reference voltage at a predetermined location of the fire suppression system, computes a continuity between the continuity probe and the predetermined location based on the feedback signal and the reference voltage, determines whether water is present in a low point of the piping system based on the computed continuity, and predicts whether a valve tripping event is expected to occur based on whether water is present in the low point to provide a detection signal for remedial action to mitigate false trips of the valve based on detecting the water in the low point.
