Heise's Plumbing recently completed a professional sewer line hydro jetting and high-definition sewer camera inspection in the Westborough neighborhood of South San Francisco, California. The property manager reported slow drains and persistent sewage backups in the main drain line. Our technicians performed a detailed diagnosis, running a camera line 160 feet into the sewer lateral. We discovered a heavy accumulation of grease blockages restricting the waste flow. Using high-pressure hydro jetting equipment, we thoroughly jetted the lateral line to scour away the grease and clear the piping in compliance with local plumbing guidelines. We then ran water while inspecting with the camera to verify that the sewer line is completely clear, free-flowing, and restored to safe, reliable operation.
