Full Product Description +
The Pentair / Sta-Rite U-3 Skimmer Weir Assembly (08650-0022) is a replacement weir door designed for Sta-Rite U-3 pool skimmers. The weir plays a critical role in controlling water flow into the skimmer, allowing surface debris to be captured efficiently while preventing debris from washing back into the pool when the pump shuts off.
A missing, cracked, or stuck weir can significantly reduce skimmer performance and lead to floating debris remaining on the pool surface.
Why the Skimmer Weir Matters
The weir door creates a controlled “spillover” effect that pulls surface debris into the skimmer basket. When functioning properly, it improves circulation efficiency and keeps debris from escaping back into the pool.
Common signs of a failing or missing weir include:
-
Poor surface skimming
-
Debris floating past the skimmer
-
Water surging or air entering the skimmer
-
Debris returning to the pool when the pump turns off
Replacing the weir restores proper hydraulic behavior at the skimmer throat.
Designed for Sta-Rite U-3 Skimmers
This weir assembly is manufactured to match Pentair / Sta-Rite OEM specifications for the U-3 skimmer body. Proper fit ensures smooth pivoting action and consistent water flow control.
Using the correct weir is essential—improper sizing or generic substitutes may bind, stick, or fail to seal correctly.
Simple, Drop-In Replacement
The U-3 skimmer weir installs directly into the skimmer opening without tools. Replacement can typically be completed in minutes and is often performed during routine skimmer maintenance or when debris control issues arise.
