No, it is absolutely not a fantastic insulator - it is a conductor. Pure water is not a good conductor, which is not quite the same thing. It becomes much more conductive, its resistance decreases, if salts are added.
As said, a flood warning unit using probes and the conduction through water is ideal for a situation which is normally dry, but becomes wet when there is a flood, such as under a washing machine. In a frequently wet Rover 75 plenum it will suffer constant false alarms.
