A drain auger is a plumbing tool used to clear clogs in pipes and drains. It consists of a long, flexible metal cable with a coiled end that can break up or retrieve blockages. When inserted into a drain, the auger can reach deep into pipes to dislodge debris, hair, or other obstructions. There are different types of drain augers, including manual and powered versions. The manual auger is operated by hand, while a powered auger uses electricity for more challenging clogs. Both types are effective for maintaining clear drainage in sinks, toilets, and other plumbing fixtures.
