Weir Door Assembly for SwimQuip® U-3 Skimmer
Product Overview
The standard OEM replacement weir door engineered specifically to restore proper surface skimming velocity on SwimQuip® U-3 skimmers.
The Pentair 08650-0022 hinged weir assembly is the genuine factory replacement for SwimQuip® U-3 in-ground pool and spa skimmers. Molded from chemical-resistant white ABS with factory-calibrated buoyancy, it maintains the precise water flow required to trap floating debris without sticking or binding in the skimmer throat. Unlike generic tension-fit doors, this genuine assembly seats cleanly into original SwimQuip hinge points for reliable, long-term flapper action.

When To Use This
Pro Tip
Before snapping the new assembly in place, inspect the hinge receiver slots inside the skimmer throat for calcium scale or plaster rough spots. Clearing buildup with a stiff nylon brush ensures the new door pivots freely without catching at low water levels.
Common Questions & Instructions
Why is a functional weir door critical for my SwimQuip U-3 skimmer?
A weir door accelerates the surface velocity of water entering the skimmer, pulling in leaves, oils, and floating debris much faster. When the pump cycles off, the door pivots upright to lock captured debris inside the basket so it cannot float back into your pool.
How do I know if my SwimQuip U-3 weir door needs replacement?
Replace your weir door if the plastic hinge pins are snapped, the flapper binds against the skimmer throat walls, or the internal buoyancy foam is waterlogged and no longer floats at roughly a 45-degree angle during pump operation.
Will the Pentair 08650-0022 fit other skimmer models?
No, the 08650-0022 is specifically engineered with molded hinge dimensions for genuine SwimQuip U-3 skimmer bodies. For other skimmer models such as Pentair Bermuda or Hayward series, model-specific weir assemblies are required.
