Plumbers And Irrigators Plumbers and irrigators, though sometimes considered one trade, specialize in different areas. Plumbers focus on installing and repairing water, waste, and drainage systems in buildings, using various materials like copper, steel, and plastic. They also install fixtures and appliances. Irrigators specialize in outdoor systems, laying pipes for sprinklers on lawns, golf courses, and farms. Both plumbers and irrigators must follow blueprints, work efficiently, and use various construction techniques depending on the project.
