Final answer:
The preferred tool for cutting PVC pipe is a Pipe cutter. It offers a clean and exact cut, whereas other tools like hacksaws are more labor-intensive and circular saws can be excessive for small pipes.
Step-by-step explanation:
The preferred tool for cutting PVC pipe is a Pipe cutter. Pipe cutters provide a clean and precise cut through PVC material with less effort compared to other tools. A hacksaw can also be used, but it tends to be more labor-intensive and can lead to a less smooth edge. Circular saws can be overkill for small PVC pipes and can create a mess with plastic shavings. A hammer and chisel is not recommended as it may result in a jagged cut and potential damage to the pipe.
