Built for compatible Jandy filtration equipment, the CS100/CS150 Tank Lid Assy is a focused replacement part for restoring the filter housing, internal water path, or service connection without replacing the full filter system. Filter components can become stressed by pressure cycles, chemical exposure, UV, and repeated cleaning, so using the right replacement helps preserve flow, sealing, and serviceability. This part is especially useful when the original piece is cracked, warped, missing, or difficult to reseat after maintenance. Confirm the filter series, square-foot rating, and part number R0461900 before ordering. This listing is best used for an exact-match replacement, not as a universal substitute. Review the product name, manufacturer, and part number R0461900 against the existing component before purchase.
