A rodding set typically refers to a collection of tools used for clearing blockages or obstructions in drainage and sewer pipes. These sets commonly include rods, sometimes known as drain rods or sewer rods, along with various attachments and accessories. The rods are usually made of sturdy materials like fiberglass or metal and come in sections that can be connected together to form a longer rod. The attachments may include items such as plunger ends, worm screw attachments, and chimney brushes, each serving a specific purpose in clearing different types of blockages.
