What material is commonly used for piping within water treatment systems?

In water treatment systems, PVC (polyvinyl chloride) is widely used for piping due to its numerous advantageous properties. PVC is lightweight, which makes it easier to handle and install compared to heavier materials. It is also resistant to corrosion and chemical damage, which is particularly important in a water treatment environment where the pipes may carry various substances and be exposed to harsh chemicals.

Additionally, PVC has excellent durability and can withstand significant pressure, making it suitable for various applications within water treatment systems. It is also cost-effective, further contributing to its widespread use in both residential and industrial water systems.

While other materials like stainless steel and polyethylene are also utilized for specific applications, PVC's balance of performance, cost, and versatility makes it a common choice for piping in these systems. Rubber, while useful in specific scenarios, is not typically used as a primary piping material due to limitations in pressure resistance and durability compared to PVC.
