Hayward DEX2420ATC Lower Filter Body with Clamp System (Tank Bottom Assembly) – Pro-Grid® DE2420
The Hayward DEX2420ATC is a genuine OEM lower filter body (tank bottom) with clamp system for the Hayward Pro-Grid vertical grid D.E. filter DE2420. This is the lower tank assembly used when the original tank bottom is cracked, warped, leaking at the seam, or damaged from freezing, overtightening, or long-term wear.

- Pool Type: In-Ground
What’s Included
- Lower filter body / tank bottom
- Clamp system to secure the upper and lower tank halves
Note: Some versions of the “with clamp system” package may be bundled as a complete clamp kit (clamp ring + metal-reinforced seal + nut/bolt hardware). Always confirm what’s included with your specific listing if you need clamp hardware and seal components.
Key Details
- Part Number: DEX2420ATC
- GTIN/UPC: 610377106917
- Replacement Part Warranty (typical): 6 months (parts only)
Common Reasons to Replace
- Cracks or leaks in the lower tank body
- Seam leaks that persist after seal replacement due to damaged tank surfaces
- Freeze damage or physical impact damage
- Warped tank flange that prevents even clamp sealing
Installation Notes
- Shut off the pump and fully relieve filter pressure at the air relief before loosening the clamp.
- Clean the tank flange and sealing surfaces thoroughly—grit is a common cause of seam leaks.
- Inspect the tank seal and replace it if flattened, nicked, or stiff; seat it evenly before clamping.
- Tighten the clamp uniformly per the filter’s instructions and re-check for seepage after restart.

Maintenance Tips
- Never loosen a clamp while the filter is pressurized—always shut off the pump and bleed air first.
- Keep the clamp band and tank flanges clean; debris under the seal can cause seam leaks.
- Lightly lubricate the tank seal with silicone-based lube to help prevent pinching and improve resealing.
- In freeze-prone areas, winterize properly by draining the filter completely to help prevent tank cracking.
