Professional drain rodding is what plumbers use when a clog is too stubborn for a plunger or chemical cleaner. They insert flexible rods down the drain, twisting and pushing to break through or retrieve blockages deep in the pipes. It's messy, hands-on work that requires a feel for the rod's resistance, often used for main sewer lines where roots or solid debris have built up. This method avoids digging up your yard, saving time and money while restoring water flow.
