The present invention discloses a device for delivering an agent, comprising: a source of agent; a body having an agent inlet for receiving agent from the source of agent and a fluid inlet for receiving fluid from a source of fluid; a mixing chamber for receiving the fluid and the agent; an outlet in fluid communication with the mixing chamber to deliver the fluid and the agent; a valve positioned between the outlet and the source of agent and configured for controlling a flow of the fluid through the fluid inlet and a flow of the agent through the agent inlet; and an actuator operatively connected to the valve and configured to: 1.) move the valve to a first configuration to deliver a first flow of the fluid substantially free from the agent through the outlet; 2.) after delivering the first flow, move the valve to a second configuration to deliver a second flow of the fluid and the agent through the outlet; and 3.) after delivering the second flow, move the valve to a third configuration to deliver a third flow of the fluid substantially free from the agent through the outlet.
