John Remstedt, co-owner of Grease Masters in St. Charles, Missouri, takes us along on a project cleaning out a city sewer main, located near a movie theater that contributes to a lot of debris in the line. When his operators use a combination sewer cleaner on jobs like these, they use Sonetics headsets. The headsets make a huge difference working around the front of these machines, Remstedt says. See why in this video.
