Clogged pipes occur when debris, grease, or foreign objects block the flow of water in plumbing systems. This blockage can lead to slow drainage, backups, and even water damage if not addressed promptly. Common causes include hair, soap scum, food particles, and tree roots infiltrating underground pipes. To prevent clogged pipes, regular maintenance is essential. Homeowners can use drain screens to catch debris and avoid pouring grease down sinks. If a clog does occur, methods like using a plunger or a plumbing snake can help clear the blockage. In severe cases, professional plumbers may be needed to resolve the issue.
