Coordinated control is the key idea here. When a tank feeds more than one urinal, automatic operation is used so the flushes can be triggered without someone having to manually operate each valve. An automatic system—often sensor-activated or centrally controlled—ensures all connected urinals flush in a predictable, timely way, improves hygiene, and helps manage water use efficiently. Manual operation would require a person to press or activate each urinal’s flush, which is impractical for multiple fixtures and loses consistency in a busy restroom. Semi-automatic would still involve some user action, defeating the goal of hands-free coordination. Hydraulic refers to a fluid-power concept and isn’t the standard method used to control multiple flushes in this context. Automatic operation is the appropriate choice for multi-urinal tank configurations.
