Which factors are critical to consider when selecting plumbing materials?

When selecting plumbing materials, several critical factors ensure the system's function, safety, and longevity. Durability is essential because plumbing materials must resist corrosion, temperature changes, pressure fluctuations, and potential impacts from other elements. This ensures that the plumbing system will last over time without significant failures or the need for frequent replacements.

Compatibility is also vital. Different materials may react adversely when in contact, leading to leaks or material degradation. Understanding which materials work well together helps create a cohesive and functional plumbing system that minimizes risks and maintains integrity.

Local code requirements are equally important. Plumbing codes dictate the standards and regulations for materials used in specific areas. Compliance with these codes is crucial to ensure safety, legality, and adherence to installation best practices. Choosing materials that meet or exceed local codes helps to avoid legal issues and ensures that plumbing installations are safe and reliable.

Considering these factors strengthens the plumbing system's design and functionality, making option B the most comprehensive and appropriate choice.
