The WGR Magnum switcher from StoneAge eliminates the need to swap nozzles mid-job, meaning fewer runs as well as less time and water required. When the pump is idled down and brought back to pressure, the tool will switch the water flow between two different patterns of jets. This allows the tool to switch between pulling and cleaning without the need to remove it from the pipe. The pulling/flushing jet pattern directs maximum power to the rear jets to pull or flush debris backwards. The cleaning/descaling jet pattern directs power to the side jets for cleaning deposits and cutting roots. It navigates pipes 8 to 36 inches in diameter and handles pressures up to 5,000 psi at up to 100 gpm. 970/259-2869; www.sewernozzles.com.
