Household drains are systems designed to carry wastewater away from sinks, showers, toilets, and other plumbing fixtures. They help prevent flooding and maintain hygiene by directing used water to the sewer system or a septic tank. Proper drainage is essential for a clean and functional home. Drains typically consist of pipes that slope downward to facilitate the flow of water. They can become clogged with debris, grease, or hair, leading to slow drainage or backups. Regular maintenance, such as using a drain snake or plumber's cleaner, can help keep household drains clear and functioning properly.
