Potable water pressure on the A320 is provided by which combination?

Explanation:
Potable water pressure on the A320 is generated by air pressure, not by electrical or hydraulic pumps. The air supply boost system uses bleed air from the engines to pressurize the potable water lines, providing a steady pressure to galley taps and lavatories throughout the flight. Electrical pumps alone wouldn’t guarantee the same regulated pressure, ground power isn’t used for in-flight pressurization, and hydraulic pressure isn’t used for the potable water system.
