Abstract: A device for removing and installing a plunger in a well head has a elongate rigid tube with a magnetic connector mechanism at it distal end for engaging the plunger during removal and installation of the plunger. A longitudinal opening or passage can be provided extending the entire longitudinal length of the rigid tube and magnetic connector mechanism. An elongate rod is positioned in the opening or passage so that the upper end of the rod can be moved downwardly to eject the lower end of the rod from the magnetic connector mechanism to thereby disconnect an attached plunger from the magnetic connector mechanism.

Abstract: A method of cleaning a linear discharge pipe that extends from a tank to a valve comprises attaching a cleaning apparatus to the discharge side of the valve on the discharge pipe. The valve is then opened and a rotating cutter head on the cleaning apparatus is advanced through the open valve and the discharge pipe until the cutter head has traversed the entire length of the discharge pipe. The rotating cutter head is then withdrawn back through the discharge pipe and the open valve. The valve is then closed and the cleaning apparatus is removed from the discharge side of the valve. Any portion of downstream piping that had been removed to allow access to the valve is then reinstalled to the discharge side of the valve.
