Hydro jetting. also called hydro flushing, is the process of using high pressure streams of water to blast clear debris in pipes and sewer systems. Hydro jetting is a chemical free process which is more effective than snaking out pipes, as the jets are able to clear the full diameter of the pipe. LoJac not only offers hydro jetting services for commercial plumbing, we also have hydro flushing services available for residential use.
