What type of tubing is suggested for refrigerator feeds to ensure optimal performance?

The suggestion for using opaque tubing for refrigerator feeds relates to the need for minimizing light exposure. In many water systems, particularly those used for food and drink applications, exposure to light can promote algae growth, which can contaminate the water supply and affect the performance of the refrigerator. Opaque tubing provides the benefit of blocking light, thus reducing the potential for biological contamination and ensuring cleaner water flows to the refrigerator.

The other types of tubing, while useful for various applications, may not offer the same level of protection against contamination. Standard PVC tubing can break down over time and might not withstand certain temperatures. Clear polycarbonate tubing, although durable, would allow light to penetrate, making it less ideal for preventing algae growth. Rubber tubing can be suitable for some applications but may degrade or leach chemicals into the water over time, potentially affecting water quality. Therefore, opaque tubing is particularly recommended to maintain water quality and optimize the performance of refrigerator feeds.
