Product Overview and Function
Pentair Sta-Rite 08650-0022 is replacement skimmer weir for SwimQuip U-3 skimmers. Weir is hinged gate that floats on water surface allowing debris to enter skimmer while preventing debris from floating back out when pump stops. Weir costs $15-$30 providing essential skimmer function.
Worn weir doesn't close properly allowing debris to escape back into pool. Broken hinge prevents weir from operating. Cracked weir sinks instead of floating. Weir replacement restores proper skimmer operation improving pool cleanliness.
The pool parts and accessories collection offers skimmer parts and replacement components.
Tools Required
No tools required for basic weir replacement. Weir installs by hand on hinge pins. Optional: flashlight for inspecting skimmer, towel for wiping hands. Simple installation requires no special tools or skills.
Removing Old Weir
Turn off pump preventing water flow during installation. Pump off makes installation safer and easier. Water flow can make weir difficult to handle.
Remove skimmer basket lifting straight up. Basket removal provides access to weir. Set basket aside in clean location. Clean basket while removed if needed.
Locate weir at back of skimmer throat. Weir is hinged gate between skimmer opening and basket area. Weir floats on water surface when pump is running. Identify weir before attempting removal.
Lift weir off hinge pins. Weir slides up and off pins. Gentle upward pressure removes weir from pins. Avoid forcing weir. Stuck weir may require wiggling to release from pins.
Inspect old weir for damage. Look for cracks, broken hinge, or warping. Understanding old weir condition confirms replacement necessity. Damaged weir validates replacement decision.
Installing New Weir
Inspect new weir verifying no shipping damage. Check hinge for cracks. Verify weir is correct model for your skimmer. Damaged or wrong weir requires exchange before installation.
Position new weir over hinge pins in skimmer throat. Align weir hinge holes with pins. Weir should be oriented with smooth side facing pool. Textured side faces basket area.
Lower weir onto hinge pins. Weir slides down onto pins. Push weir down until fully seated on pins. Proper seating ensures weir operates correctly. Verify weir moves freely on pins.
Test weir movement by hand. Weir should swing freely on hinge. Stiff movement indicates improper installation or defective weir. Free movement is essential for proper operation.
Reinstall skimmer basket. Basket should not interfere with weir operation. Verify basket sits properly in skimmer. Improper basket installation can prevent weir from closing.
The pool cleaners collection offers equipment for maintaining clean pool.
The pool chemicals collection provides water treatment products.
Testing Weir Operation
Start pump and observe weir operation. Weir should float open allowing water to flow into skimmer. Floating weir indicates proper installation and operation. Sinking weir indicates defective weir or improper installation.
Stop pump and observe weir closure. Weir should swing closed preventing debris from floating back out. Closing weir confirms proper operation. Weir that doesn't close indicates problem requiring correction.
Add debris to pool near skimmer testing debris capture. Debris should enter skimmer and remain trapped when pump stops. Proper weir operation keeps debris in skimmer. Debris escaping indicates weir problem.
Verify basket doesn't interfere with weir. Remove basket and check weir operation. If weir works without basket but not with basket, basket is interfering. Adjust basket position or replace damaged basket.
Troubleshooting Common Problems
Weir doesn't float: indicates weir is waterlogged or defective. Weir should be buoyant floating on water surface. Sinking weir requires replacement. Verify weir is correct model for skimmer.
Weir doesn't close: indicates broken hinge, improper installation, or basket interference. Check hinge for damage. Verify weir is properly seated on pins. Remove basket testing weir operation. Address identified problem.
Weir sticks open or closed: indicates debris on hinge pins or bent pins. Remove weir and clean hinge pins. Inspect pins for bending. Clean pins restore smooth operation. Bent pins require professional skimmer repair.
Debris escapes skimmer: indicates weir not closing properly or gaps around weir. Verify weir closes completely. Check for damage preventing full closure. Gaps around weir indicate wrong weir model or damaged skimmer throat.

Weir Maintenance
Clean weir monthly removing accumulated oils and debris. Oils from sunscreen and lotions coat weir affecting buoyancy. Rinse weir with hose. Scrub with soft brush if needed. Clean weir maintains proper operation.
Inspect weir quarterly for cracks or damage. Cracked weir loses buoyancy requiring replacement. Early damage detection allows planned replacement. Quarterly inspection prevents unexpected weir failure.
Lubricate hinge pins annually using silicone spray. Lubrication ensures smooth weir movement. Spray pins with weir removed. Wipe excess lubricant. Annual lubrication extends weir life.
Replace weir every 3-5 years preventively. Weir degrades from UV exposure and chemicals. Preventive replacement ensures reliable operation. Weir replacement is inexpensive maintenance preventing skimmer problems.
