When water refuses to drain from your sink, shower, or tub, professional drain rodding is often the solution. A technician feeds a flexible metal cable into the pipe, manually cranking it to break up clogs of soap scum, hair, and grease. Unlike harsh chemicals that can damage old plumbing, rodding physically clears the blockage without corroding pipes. It's a messy job, but effective for stubborn backups that plungers can't budge.
