The Warthog WGR Magnum high-performance rotary nozzle from StoneAge operates for long periods between maintenance intervals. It can effectively handle recycled water, retaining jet quality under poor water conditions. Its streamlined design allows for better forward and reverse movement through pipe. Hardened steel centralizer fins can be replaced individually as wear occurs, further protecting the tool for longer operation in the field. 866/795-1586; www.sewernozzles.com.
