Switcher cleaning heads from StoneAge eliminate extra runs by switching between pulling and descaling jets. Technicians can use the same tool to quickly run down the line, then engage full cutting force to clear obstructions, and switch again to move debris. Every time the pump is idled down and brought back to pressure, the tool alternates function between two different sets of jets. Field use of the WGR Magnum with Switcher head versus the traditional method of using two tools (rotational and fixed nozzle) demonstrates up to 35 percent less water usage and job times close to 50 percent faster. 866/795-1586; www.sewernozzles.com.
