An automatic animal watering system has a manifold for transporting drinking water, a controlled volume dispenser in the manifold for receiving a volume of drinking water, an inlet valve, and an outlet valve. A plurality of drinking valve assemblies is provided in fluid communication with the manifold between the inlet and outlet valves. A fluid sensor, capable of responding to changes in one or both of the water volume and pressure, is provided in the manifold between the inlet and outlet valves. The volume of drinking water available to the drinking valve assemblies can be regulated as a function of time to limit maximum potential leakage. The system also includes a controller receiving signals from the fluid sensor and generating a response to changes in the monitored water volume or pressure, thereby limiting potential water leakage in the system.
