The method includes the steps of: providing a first flexible tube; placing the tube at a first operating location with respect to the system; and directing a pressurized fluid through the tube in a manner whereby the first flexible tube is moved in a whipping action to at least one of: a) impact the surface assembly; b) direct the pressurized fluid at least one of: i) into the flowable material moving between the first and second locations; and ii) against the surface assembly; and c) move within the flowable material moving between the first and second locations, thereby to at least one of: i) break loose flowable material adhering to the surface assembly; and ii) agitate flowable material moving between the first and second locations. ## Claims ### Claim 1 A method of inducing the movement of a flowable material in a system wherein the flowable material is guided by a surface assembly between first and second locations, the method comprising the steps of: providing a first flexible tube;
