Aumzong Filter Tank Bottom Assembly for Pentair Clean & Clear Plus / Quad DE CCP240-CCP520 – OE 178578, Reinforced Durable Base

The Aumzong 178578 Filter Tank Bottom Assembly is a direct-fit replacement base for Pentair Clean and Clear Plus and Quad DE filter models (CCP240/CCP320/CCP420/CCP520), engineered to support filter media and keep pool water running clean.

If your Pentair DE filter needs a reliable base after wear, corrosion, or accidental damage, this Aumzong 178578 replacement provides a rugged, OE-matched option. Built from reinforced materials, it restores the filter’s structural core so the internal elements—plates, frames, or cartridges—remain aligned and sealed properly under normal operating pressure.

How does this replacement part restore filter performance?

Replacing a compromised tank bottom returns the core support that holds filter media in position and preserves the internal flow geometry. That ensures consistent debris capture and prevents uneven pressure that can shorten other filter components’ life.

• Fits original Pentair OE number 178578 for correct alignment.
• Secures filter elements and plates to prevent sagging or shifting.
• Restores proper backwash and filtration flow paths.

Will the Aumzong 178578 fit my Pentair Clean and Clear Plus or Quad DE model?

This assembly is designed specifically to be compatible with Pentair Clean and Clear Plus and Quad DE models CCP240, CCP320, CCP420, and CCP520. Confirm the OE number and top cover reference to ensure a match before ordering.

• OE reference: 178578 for direct compatibility.
• Applicable top cover reference: 170024 for cross-checking fit.
• Works with both Clean and Clear Plus and Quad DE filter families listed.

What materials and durability features should I expect?

Aumzong manufactures this bottom assembly from reinforced, durable materials chosen to resist corrosion and mechanical stress in pool environments. The robust construction reduces the chance of deformation under pressure and extends the service life of the filter assembly.

• Rugged, long-life construction designed for pool chemical exposure.
• Reinforced mounting points to support filter media weight.
• Precision molding to match OEM sealing surfaces and bolt patterns.

How should I install and maintain the replacement tank bottom?

Installation typically involves draining the tank, removing the old base, and bolting the new assembly into place while checking gaskets and hardware for wear. Routine inspection during seasonal service helps catch leaks or loose fasteners early so the filter performs reliably.

• Drain and depressurize the filter before disassembly.
• Replace worn gaskets and inspect bolts when installing the new base.
• Perform seasonal checks for alignment, cracks, or corrosion.

Who is this for: Pool owners, service technicians, and maintenance shops that operate Pentair Clean and Clear Plus or Quad DE filters and need a dependable replacement base to restore proper support for filter media. Choose this Aumzong 178578 assembly when you require an OE-referenced, durable solution that returns your DE filter to correct mechanical condition without replacing the entire tank.
