Main Line Rodding: What It Is and When You Need It

Main line rodding is a maintenance and repair method used to clear obstructions in the main drain line—the pipe that carries wastewater away from sinks, showers, toilets, and appliances toward the sewer or septic system.

Rather than working on a single fixture (like a clogged bathroom sink), rodding targets the shared “main” section of plumbing that serves the entire home’s waste disposal route.
