Which type of pipe is commonly used for water distribution in building plumbing?

The correct answer is that all of the listed pipe types—PVC, CPVC, and PEX—are commonly used for water distribution in building plumbing systems. Each of these materials has its own unique properties and applications, making them suitable for various plumbing conditions.

PVC, or polyvinyl chloride, is widely known for its durability and resistance to corrosion, making it an ideal choice for cold water supply lines. Its lightweight nature and cost-effectiveness also contribute to its popularity in residential and commercial plumbing.

CPVC, which stands for chlorinated polyvinyl chloride, is similar to PVC but has been treated to withstand higher temperatures, allowing it to be suitable for both hot and cold water distribution. Its thermoplastic properties make it flexible and easy to work with, especially in applications where hot water is needed.

PEX, or cross-linked polyethylene, has gained popularity in modern plumbing installations due to its flexibility, resistance to scale and chlorine, and ability to expand and contract without cracking. PEX can be used for both hot and cold water lines, and its ease of installation often results in reduced labor costs.

Due to the varied strengths and applications of these materials, they are all viable choices for water distribution in building plumbing systems, leading to the conclusion that all
