Sewer rodding is a process used to clear clogs, obstructions, or debris from a sewer line. It's a common method for addressing blockages that occur in residential or commercial plumbing systems. Here's a detailed description of the sewer rodding process:

1. Inspection

Initial Assessment: Before the rodding process begins, a plumber or technician usually conducts an inspection to determine the location and severity of the blockage. In many cases, a sewer camera inspection is used to identify the specific issue.

2. Preparation

Access Point: The plumber identifies the cleanout point, which is a pipe segment that provides easy access to the sewer line. This cleanout is typically located in a basement, crawlspace, or outside near the home or building.

Safety Precautions: The plumber may wear protective equipment and ensure that the rodding machine and tools are functioning correctly before starting the process.

3. Inserting the Rodding Tool

Rodding Machine: The main tool used in this process is a sewer rod or a flexible metal rod attached to a mechanical rodding machine. These rods are long, flexible, and durable, allowing them to navigate the bends and curves of the sewer line.

Insertion: The plumber slowly feeds the rod into the sewer line through the cleanout. The rod is flexible enough to move through the pipes and reach the clog, even if the pipes have twists or turns.

4. Clearing the Clog

Breaking Through the Blockage: Once the rod reaches the clogged area, the plumber will work the rod back and forth, rotating it if necessary, to break up the blockage. Some rods have rotating heads, cutting blades, or auger attachments to help break apart more stubborn clogs like tree roots, grease, or debris.

Multiple Passes: Depending on the severity of the blockage, multiple passes may be necessary to fully clear the obstruction and ensure the sewer line is flowing freely.

5. Flushing the Line

Water Flush: After the blockage has been cleared, the plumber may flush the sewer line with water to ensure that all debris has been fully removed. This flush helps verify that the line is draining correctly and no partial blockages remain.

6. Final Inspection

Post-Work Inspection: After rodding, the plumber may conduct another camera inspection to confirm that the sewer line is clean and free of debris. If any obstructions remain, they may repeat the process or use another technique, such as hydro-jetting.

7. Clean-up and Conclusion

Clean up: Once the line is cleared, the equipment is removed, the cleanout is closed, and the area is cleaned. The plumber may also provide advice on how to prevent future blockages.

When to Use Sewer Rodding: Slow drains or sewage backups in multiple fixtures. Repeated clogs that don't respond to plunging or other DIY methods. Tree roots or other large obstructions in the main sewer line. Debris build-up over time (e.g., grease, paper products, or other foreign objects).

Advantages of Sewer Rodding: Effective for removing solid blockages like roots, debris, or grease. Cost-efficient compared to other methods, such as excavation or pipe replacement. Can be used on both residential and commercial sewer systems.

Limitations: May not work for severely damaged or collapsed pipes. Some blockages (e.g., heavy root intrusion) might require more intensive methods like hydro-jetting. Sewer rodding is a key method used in routine sewer line maintenance, preventing more costly repairs or replacements by addressing blockages early on.
