Hayward CX1750B Filter Head with Directional Vent Valve
Part # CX1750B — a genuine replacement filter head designed for the Hayward Star-Clear Plus C1750 and C1900 cartridge filters. This assembly includes the lid and built-in directional air-vent to provide proper cartridge filtration and safe maintenance access.
Key Features
- Designed specifically for Hayward Star-Clear Plus C1750 / C1900 models.
- Includes directional vent valve to purge trapped air safely during start-up.
- Factory original lid assembly ensures correct fit, sealing, and reliability.
- Constructed of durable thermoplastic material engineered for pool chemical environments.
- Easy to service — ideal when lid cracks, vent leaks, or vent valve fails.
Typical Applications
This filter head is used when the lid on a C1750 or C1900 cartridge filter shows signs of deterioration, damage (cracks or leaks), malfunctioning vent valve, or when you simply want to restore proper filter operation without replacing the entire tank. It’s ideal for residential in-ground pool systems using the Star-Clear Plus series.
Installation & Compatibility Notes
Before servicing, turn off the pump and relieve system pressure. Remove the clamp ring and lift the lid from the filter tank. Inspect the gasket and rim for wear. Install the CX1750B lid assembly, align the gasket and secure the clamp. Re-pressurize the system and verify no leaks occur at the seal or vent valve. Confirm proper ventilation and safe operation through one full cycle.
Why Choose This Lid Assembly?
Choosing the genuine CX1750B lid assembly ensures the correct geometry, threading, vent integration and sealing performance expected by the original manufacturer. It helps maintain filter efficiency, prevents air ingestion, reduces risk of blow-off, and extends the life of the cartridge filter system.
Maintenance Tips
- Inspect the lid coupon annually for cracks, discoloration or vent valve seepage.
- Check the O-ring sealing groove for cuts, flattening or embedded debris—replace the O-ring if damaged.
- Ensure the clamp ring is properly torqued and the lid is evenly seated to maintain a uniform seal.
- If the directional vent valve drips or fails to close, replacing the lid assembly now avoids internal damage or cartridge bypass.
