The top elbow and diffuser assembly helps guide incoming water into the sand filter tank so it can spread across the media bed instead of channeling in one concentrated area. This Hayward replacement assembly is designed for compatible S311SX sand filters. A cracked elbow, missing diffuser, or worn internal connection can reduce filtration quality and put stress on other components. Replacing the assembly helps preserve proper flow distribution and supports more even use of the sand bed.
