How is the water system in the galley and LAV controlled?

The water system in the galley and lavatory is controlled from the water system control panel in the galley. This panel is specifically designed to allow flight attendants to manage the water supply for sinks, lavatories, and other water-dependent functions on the aircraft. By using this control panel, crew members can ensure that adequate water is available for passenger needs and other operations throughout the flight.

The integration of the control panel within the galley highlights the importance of having essential systems centralized in operational areas where flight attendants are stationed, allowing for quick and efficient access. Additionally, having a dedicated control panel simplifies the process, ensuring that water management can be easily handled without the need for accessing other areas of the aircraft like the cockpit or passenger cabin.
