A method and apparatus for installing a cable in a tube is provided wherein the cable is installed by the combination of a pushing force and a pressurized fluid drag force. In particular, the pressurized fluid drag force is applied by alternately passing a first pressurized fluid having first hydrodynamic properties and a second pressurized fluid having second (different) hydrodynamic properties into the tube at substantially a same location.
