Abstract : A tube blockage tester or a blockage eliminator is provided which includes a manifold which has a forward end and a rearward end. A nozzle is provided at each end of the manifold with one of the nozzles being directed forwardly and the other nozzle being directed rearwardly. The manifold is adapted to receive a fluid pressure supply line. A valve is mounted in the manifold for selectively controlling pressurized fluid to the nozzles. A reel, which has a line reeled thereon, has a plurality of vanes around its circumference. The reel is mounted on the manifold aft thereof with the vanes of the reel in the path of the rearward nozzle so that when fluid is ejected from the rearward nozzle the reel will wind the line thereon. A probe is provided which is capable of slipping into the tube and the line is connected to the probe. With this arrangement the forward nozzle can be operated by the valve to force the probe through the tube and the rearward nozzle can be operated to retract the probe by winding the line on the reel.
