Quick Product Summary

The Swimables SW-27-400 Hayward Style DE Manifold is an aftermarket replacement top collector manifold designed for Hayward-style DE filter applications. It is commonly listed as a replacement for Hayward DEX2400C and is used with Hayward Pro-Grid and Micro-Clear DE filters that require this manifold design. Use this part when your existing DE filter manifold is cracked, warped, leaking internally, or no longer distributing water properly through the filter grid assembly. Public product listings describe SW-27-400 as a Swimables manifold for Hayward Micro Clear and Pro-Grid DE filters with a built-in breather tube.

Best For

• Hayward-style DE filter manifold replacement
• Hayward Pro-Grid DE filters
• Hayward Micro-Clear DE filters
• Replacing Hayward DEX2400C-style top collector manifolds
• DE filters with cracked, warped, or damaged manifolds
• Pool owners matching Swimables SW-27-400 or Hayward DEX2400C

Why This Matters

• A cracked manifold can allow DE powder or debris to return to the pool
• A damaged manifold can reduce filtration performance and internal water distribution
• Proper manifold fit helps the DE grids seal and align correctly
• Replacing the correct manifold can help restore filter efficiency without replacing the full filter
• Built-in air relief helps support proper filter operation
• Matching the filter model and manifold style helps avoid wrong-part orders

Common Signs You Need This / Use This When

• Use this manifold when the original Hayward-style DE manifold is cracked or broken
• Use this replacement when DE powder is returning to the pool after startup
• Common signs may include cloudy return water, damaged internal filter parts, or poor filtration after backwashing and cleaning
• Replace the manifold when the breather tube, collector ports, or top manifold body is damaged
• Use this part when your filter parts diagram calls for Hayward DEX2400C or a verified Swimables SW-27-400 replacement
• Inspect grids, standpipe O-ring, air relief parts, and the filter tank seal at the same time

Product Specifications

Compatibility / Fitment Notes

The Swimables SW-27-400 is commonly listed as a Hayward-style DE filter manifold replacement for Hayward Pro-Grid and Micro-Clear filters. Several product references describe it as a replacement for the Hayward DEX2400C top collector manifold and note the built-in breather tube design.

Hayward’s DEX2400C top collector manifold is used with MicroClear and Pro-Grid vertical grid DE pool filters. Pool parts references commonly associate the DEX2400C manifold with Hayward DE2420, DE3620, DE4820, DE6020, and DE7220 filter models.

Before ordering, confirm your filter model number, manifold part number, grid assembly style, standpipe alignment, and air relief configuration. Do not assume this manifold fits every Hayward DE filter, cartridge filter, sand filter, or non-Hayward-style DE filter.

Installation / Use Notes

Turn off the pool pump and relieve all filter pressure before opening any DE filter tank. Follow the filter manufacturer’s service instructions and never open a pressurized filter.

When replacing the manifold, inspect the DE grids, grid frame, standpipe O-ring, air relief tube, tank O-ring, and internal support parts. A cracked manifold can cause DE bypass, but damaged grids or worn seals can also allow DE powder to return to the pool. After reassembly, recharge the filter with the proper amount of DE for your specific filter model.

Buy with Confidence

Benchmark Pool Supply helps pool owners and service professionals identify the right filter replacement parts by brand, part number, and filter model. DE filter manifolds can look similar, but port spacing, grid alignment, air relief design, and standpipe fit matter. Matching Swimables SW-27-400 to the correct Hayward-style DE filter helps avoid wrong-part orders and supports proper filtration performance.
