Hayward ECX5000BP Filter Head with Vent Valve (Platinum) for Perflex Extended-Cycle D.E. Filters
The Hayward ECX5000BP is an OEM filter head (top cover) with integrated vent valve for Hayward Perflex extended-cycle D.E. filters. This is the upper head that clamps to the filter body and provides the mounting point for the internal bump mechanism, while the vent valve helps bleed trapped air during startup and service.

Maintenance Tips
- Always shut the pump off and bleed pressure before opening the filter.
- Keep the clamp band and sealing surfaces clean—grit can cause leaks and uneven clamp tension.
- Lubricate large O-rings lightly with a silicone-based pool lubricant to reduce pinching and improve sealing.
- If you see D.E. returning to the pool, inspect internal gaskets/diaphragm components during your next service.
