Plumbing repair involves fixing issues related to water supply and drainage systems in homes and buildings. Common problems include leaky faucets, clogged drains, and broken pipes. These repairs can help prevent water damage and ensure that plumbing systems function properly. To perform plumbing repairs, tools like wrenches, plungers, and pipe cutters are often used. Homeowners can tackle minor issues themselves, but more complex problems may require the expertise of a professional plumber. Regular maintenance can also help avoid costly repairs in the future.
