Pentair Almond Bottom Tank Assembly Replacement Pool and Spa Filter | 178578

Pentair Almond Bottom Tank Assembly Replacement Pool and Spa Filter | 178578

The Pentair Bottom Tank Assembly (part number 178578) is an almond-colored replacement base for select Pentair pool and spa filters. This component forms the lower half of the filter body and is essential for maintaining a secure seal, housing the internal manifold and support structures. It is made for systems where the original tank base has cracked, warped, or become compromised due to age or pressure-related stress.

This tank assembly is designed for direct replacement and uses the existing clamp, top half, and internal components. The almond finish matches the original color used on compatible Pentair filter models for a consistent appearance.

Features:

• Genuine Pentair replacement bottom tank
• Almond color for original factory match
• Designed to work with existing top dome and clamp
• Supports internal filter components and plumbing connections
• Built to handle normal operating pressure in pool and spa systems
• Durable construction suited for outdoor equipment pads

Commonly Fits:

Pentair Clean & Clear Plus and similar filter systems (verify part diagrams)

Filters using split-tank design with clamp ring connection

Notes:

Always check your filter’s model number and exploded parts diagram to ensure compatibility. This part includes only the bottom tank half; upper dome, cartridge elements, clamp, and o-rings are sold separately.

Please Note: These will not work for D.E. style Filters.
