A drain auger, also known as a plumbing snake, is a tool used to clear clogs in pipes and drains. It consists of a long, flexible metal cable with a coiled end that can navigate through pipes. When inserted into a drain, the auger can break up or retrieve blockages, allowing water to flow freely again. Using a drain auger is often a more effective solution than chemical drain cleaners, which can be harsh on pipes. This tool is commonly used by both professionals and homeowners to maintain plumbing systems and prevent future clogs.
