Which type of pipe requires little specialized training to work with?

The correct answer is polyvinylchloride (PVC) because working with PVC requires minimal specialized training compared to other types of piping. PVC is widely used in plumbing systems and construction due to its versatility, lightweight nature, and corrosion resistance. It can be cut and joined through relatively simple methods, such as using solvent cement, which does not require advanced tools or techniques. This accessibility makes it a popular choice for both professionals and DIY enthusiasts.

In contrast, working with galvanized pipe involves threading and cutting, which requires a certain level of skill and specialized tools. Soft copper requires careful handling and techniques like bending and soldering that can be more technical and require specific training to avoid leaks. Hard copper is even more complex, as it often involves welding and requires high-temperature soldering skills along with specific safety precautions to manage the heat and materials involved. Each of these other types of piping necessitates a greater understanding of techniques, safety considerations, and tools, making them less accessible for those without specialized training.
