Plumbing is the system of pipes, fixtures, and other equipment used to bring clean water into buildings and remove waste water. It plays a crucial role in maintaining hygiene, comfort, and convenience in homes and businesses. Plumbers install and repair sinks, toilets, water heaters, and drainage systems. Good plumbing helps prevent water leaks, which can cause damage and increase water bills. Overall, plumbing is essential for healthy and safe living environments.
