Plumbers are skilled tradespeople who install and maintain water supply, drainage, and sanitation systems in residential, commercial, and industrial buildings. They work with pipes, fixtures, valves, and appliances such as water heaters, sinks, toilets, and showers, ensuring clean water delivery and safe waste removal. Plumbers interpret blueprints, diagnose leaks or blockages, and use specialized tools to cut, join, and test piping systems. They must understand local building codes and environmental regulations to ensure systems function efficiently and safely. Many plumbers undergo apprenticeships and earn certifications to demonstrate expertise. Their work is essential for public health, preventing contamination and promoting hygiene. Whether repairing a burst pipe or installing a new bathroom, plumbers provide critical services that support daily living and comfort in homes and workplaces.
