Modular Faucet System for Aircraft

A method of removing and replacing a modular faucet system on an aircraft, comprising:

• removing one of a faucet outlet, a flow valve, and an actuator from a lavatory on an aircraft without removing an other of the faucet outlet, flow valve, and actuator from the lavatory, wherein the faucet outlet, flow valve, and actuator are separate components of a modular faucet system, wherein the flow valve is connected to a water supply by a first water line, wherein the water supply comprises a water tank on the aircraft, wherein the flow valve is connected to the faucet outlet by a second water line, and wherein the actuator comprises a touchless sensor configured to detect a user of the modular faucet system and is configured to generate a control signal to open the flow valve to provide water from the water supply to the faucet outlet in response to detection of the user by the touchless sensor;
• and
• replacing the one of the faucet outlet, the flow valve, and the actuator removed from the lavatory without replacing an other of the faucet outlet, the flow valve, and the actuator.
