What is a common application for PEX pipe in plumbing?

PEX pipe, or cross-linked polyethylene pipe, is widely utilized for water distribution in both residential and commercial buildings due to its flexibility, resistance to scale and chlorine, and lower shipping costs. Its ability to expand allows it to withstand freeze damage better than rigid piping materials.

Additionally, PEX is easy to install and can be snaked into walls and around corners without the need for joints, which reduces the potential for leaks. This makes it especially advantageous in situations where space is confined or where extensive routing is necessary.

While other materials are employed for drainage systems, waste disposal, and ventilation, PEX is not suited for carrying waste or venting gases due to its lower resistance to temperature and chemicals found in those applications. Therefore, the primary and most common application for PEX pipe remains the distribution of potable water in various building setups.
