What tool do you use to clear pipe?

The closet auger is specifically designed for your intended purpose of clearing clogs from toilets and other fixtures. This tool features a long, flexible shaft with a crank handle and a curved end that effectively navigates the bends within plumbing systems, allowing it to reach obstructions and clear them away. Unlike other tools, the closet auger is specifically tailored for use in restroom environments where clogs commonly occur.

For further context, hickeys are typically used for bending pipes, unions connect two segments of pipe, and fish tape is utilized for pulling wires through conduits. While all of these tools have their respective uses in plumbing and electrical work, they are not suited for clearing blockages in toilets or similar fixtures, which makes the closet auger the correct choice for this task.
