CMP 25141-440-000 Spring-Lock Skimmer Weir Door (8-3/8″)
The CMP 25141-440-000 is a replacement spring-lock weir door designed to fit many common pool skimmers, including models like the SwimQuip U-3 and Hayward SP1070 series. It helps maintain proper skimming action by allowing surface water and debris to flow into the skimmer basket while preventing return flow — essential for keeping pools clean and circulation efficient.
Key Features
- Spring-loaded weir door — opens automatically when water flows into the skimmer and closes when flow stops, preventing debris from floating back out.
- 8-3/8″ width — fits standard skimmer openings that accept this size.
- Durable, chemical- and UV-resistant construction — designed for long-term use in pool environments.
- Direct replacement part — ready to install in compatible skimmer housings without modification.

When to Use / Replace
Install this weir door when the existing skimmer door is cracked, warped, missing, or fails to close properly — conditions which reduce skimmer efficiency or allow debris to escape. A properly functioning weir ensures consistent surface skimming, improving pool cleanliness and reducing load on the filtration system.
Installation & Maintenance Tips
- Turn off the pump before servicing the skimmer. Remove the old weir and clean the mounting area thoroughly.
- Snap the new spring-loaded weir door into the skimmer pivot slots — the spring-lock design ensures secure placement without extra hardware.
- Check that the weir opens and closes smoothly and seals tightly when water flow stops.
- Inspect annually for wear, cracking, or stiffness — replace if the weir no longer moves freely or fails to seal properly.
