When a sewer line gets clogged with grease, roots, or debris, water jetting sends a high-pressure stream through the pipe to blast away the blockage and clean the walls. It's like a power wash for underground drains, often done from a truck-mounted rig with a hose that snakes through manholes. This method clears slow drains and prevents backups without harsh chemicals.
