A plumber's snake, also known as a drain snake or auger, is a tool used to clear clogs in plumbing systems. It consists of a long, flexible metal cable with a coiled end that can navigate through pipes. When inserted into a drain, it can break up or retrieve blockages caused by hair, grease, or other debris. Using a plumber's snake is often a more effective solution than chemical drain cleaners, which can damage pipes. The tool is available in various sizes, making it suitable for both residential and commercial plumbing needs. Proper use can help maintain clear and functional drainage systems.
