A sidespray for use with a water faucet unit includes a trigger valve and a volume control valve. The trigger valve is configured to define a full-ON water flow condition and a full-OFF water flow condition for the sidespray. A diverter actuator is coupled to the trigger valve to select between the full-ON water flow condition and the full-OFF water flow condition for the sidespray. The volume control valve is configured to define a volume-variable water passageway to limit a water flow volume through the sidespray when the trigger valve has set the sidespray to the full-ON water flow condition. A volume control actuator is coupled to the volume control valve to selectively adjust the water flow volume through the sidespray.
