Hydro-Jetting is a drain cleaning service that properly releases any clogs in your drain or sewer line. Hydro-Jetting, or Water Jetting, is a process in which highly pressurized water is used to clean and maintain pipes and drains. It works by pushing debris out of pipes and pulverizing solid objects like tree roots. When it comes to grease and other slimy products, hot water hydro jetting is an effective form of plumbing maintenance and performs better than the cable-line option of sewer rodding.
