Plumbing is a system of pipes, fixtures, and fittings designed to convey water, waste, and heating fluids within a building. It includes the installation, repair, and maintenance of pipes, valves, faucets, and fixtures. Plumbing systems ensure the efficient distribution of clean water for drinking, cooking, and sanitation, while also handling waste and sewage disposal. Proper plumbing is crucial for maintaining hygiene, preventing leaks, and avoiding water damage. It involves a range of tasks from designing and installing new systems to troubleshooting and repairing existing ones, often requiring specialized knowledge and skills to address complex issues and ensure system reliability.
