When a sewer line is completely blocked, using mechanical rodding or jetting equipment is the most effective approach. These methods are designed to physically remove the obstruction. Mechanical rodding involves using a flexible rod to dislodge blockages, such as grease, tree roots, or debris, enabling the free flow of wastewater. Jetting equipment, on the other hand, utilizes high-pressure water jets to clear clogs and clean the inner walls of the sewer line.

These techniques not only address the immediate blockage but also help maintain the line’s overall integrity and functionality. Unlike other approaches that might only offer temporary relief or fail to effectively resolve the issue, mechanical rodding and jetting are proactive measures that can prevent more serious problems in the future, such as backups or overflows, making this the preferred course of action in the scenario of a complete blockage.
