What customers say
Owners highly value this genuine OEM tank bottom assembly for its perfect fit and immediate restoration of optimal D.E. filter performance. The core sentiment centers on functional quality and reliability; the part seamlessly integrates, resolving issues like grid instability. While the assembly performs exactly as intended, maintaining structural integrity, customer enthusiasm is tempered by the high cost of this proprietary component. Users express mild frustration that this expensive part requires replacement after several seasons, especially given the chemical demands on plastic components. Installation is manageable for experienced users. Overall, satisfaction stems from the assembly effectively extending the life of a premium filtration system, despite the necessary expense.
