Plumbing work encompasses the installation, repair, and maintenance of plumbing systems that convey water, gas, and waste in residential, commercial, and industrial buildings. This includes installing and repairing pipes, fixtures (e.g., sinks, toilets, showers), and appliances (e.g., water heaters, dishwashers). Plumbers also address issues like leaks, clogs, and low water pressure. They use specialized tools and equipment to diagnose problems and perform repairs efficiently. 

Proper plumbing is essential for health, sanitation, and comfort, making professional plumbing services crucial. Plumbers ensure systems meet building codes and regulations, ensuring safety and efficiency in water distribution and waste disposal.
