Hayward CX5030C Top Manifold Assembly for C5030/C7030 SwimClear Cartridge Filter — OEM Replacement, Leak-Resistant Seal

The Hayward CX5030C top manifold assembly is the exact OEM replacement piece that restores correct water flow and cartridge alignment in Hayward C5030 and C7030 SwimClear in-ground filters.

If your SwimClear cartridge filter is leaking, not seating properly, or showing poor circulation, the top manifold is often the cause. This precision-molded Hayward component secures the filter cartridge(s), routes water evenly through the pleats, and seals against the tank to maintain filtration efficiency. Installing a correct OEM manifold avoids fit issues seen with generic parts and helps preserve the original performance of your filtration system.

What does the CX5030C top manifold do inside my SwimClear filter?

The top manifold centers and seals the cartridge element while channeling water into and out of the filter assembly. It also supports the cartridge under pressure and aligns ports with the filter housing so the internal plumbing works as designed.

• Provides a pressure-resistant seal against the filter tank.
• Aligns cartridge pleats to ensure even flow and filtration.
• Integrates inlet/outlet ports that match Hayward plumbing tolerances.
• Transfers mechanical load away from the cartridge to the housing.

How will replacing the top manifold affect pool performance?

Swapping a worn or cracked manifold restores proper circulation and reduces bypass or uneven filtration that can cloud water. A correct manifold keeps pressure readings stable and helps the cartridge trap debris more efficiently, which can extend cartridge life.

• Reduces risk of leaks at the tank top seal.
• Improves debris capture and water clarity by preventing flow short-circuits.
• Helps maintain consistent filter pressure and pump load.

Is this Hayward part easy to install and does it fit my model?

The CX5030C is manufactured to fit Hayward C5030 and C7030 SwimClear in-ground cartridge filters without modification. Basic hand tools and a few minutes are typically all that’s needed for removal of the old top and installation of the new manifold, provided the rest of the housing is intact.

• Direct OEM fit for C5030 and C7030 models — no trimming required.
• Installation usually requires only common tools and a safe depressurization of the system.
• Replace the O-ring or gasket during installation for best sealing performance.

What should I inspect before and after replacing the manifold?

Before you install, confirm the filter body and cartridge are free from large cracks or warping; a new manifold cannot compensate for a damaged tank. After replacement, run the system and check for leaks, pressure stability, and improved clarity as signs of successful installation.

• Inspect housing flange and threads for damage or corrosion.
• Replace any worn O-rings and clean seating surfaces thoroughly.
• Start pump gradually and monitor for leaks and steady pressure gauge readings.

Who is this for: The Hayward CX5030C top manifold is intended for pool owners, service technicians, and dealers maintaining Hayward SwimClear in-ground cartridge filters C5030 and C7030. Choose this genuine Hayward replacement when your existing manifold shows cracks, warped fittings, or leak paths, or whenever you want an OEM-fit part to restore original filtration performance and avoid compatibility issues with aftermarket alternatives.
