Which tool is commonly used for plugging leaks in piping systems?

The tool that is commonly used for plugging leaks in piping systems is a wooden wedge or repair clamp. Wooden wedges can be driven into a leaking joint to create a seal, especially in situations where the leak is caused by a crack or gap in the pipes. This method is particularly effective for temporary fixes.

Repair clamps are also designed specifically for this purpose. They provide a sturdy and reliable way to compress the damaged area of the pipe, effectively stopping the leak until a more permanent repair can be made. Using a repair clamp can help restore the integrity of the piping system under pressure, which is essential in maintaining functionality and preventing further damage.

In contrast, tools like screwdrivers or wrenches are generally used to tighten or adjust fasteners rather than to directly address leaks. Pipe cutters or benders are designed for cutting or manipulating pipes but do not serve to plug leaks. Similarly, drills or saws are intended for creating holes or cutting through materials, rather than sealing or repairing leaks in pipes.
