Waterway 550-9950 Renegade Skimmer Weir Door Assembly (White)

The Waterway 550-9950 is a replacement weir door (flapper) for select Waterway Renegade in-ground (gunite) pool skimmers. The weir door helps maintain proper surface skimming by creating a controlled “floating” barrier at the skimmer opening—allowing debris to enter while helping reduce backflow when the pump shuts off.

Key Functions

  • Improves surface skimming by stabilizing flow into the skimmer
  • Helps keep leaves and debris from drifting back into the pool when circulation stops
  • Assists with consistent skimmer performance across normal water-level changes

Compatibility

  • Designed for select Waterway Renegade in-ground (gunite) skimmers
  • Always compare dimensions and hinge/pin spacing to your existing weir before ordering (Renegade skimmers can vary)

Specifications

  • Part Number: 550-9950
  • Color: White
  • Approx. Door Size: ~5.5" W x 8.125" H
  • Overall Approx. Size: ~8.75" L x 5.4" W x 1" D
  • Approx. Pin-to-Pin Spacing: ~8.6875" (8 11/16")
  • Replaces Older Part Numbers: 542-6300, 519-9560

Signs You Need a New Weir Door

  • Weir is warped, cracked, or missing
  • Door sticks, won’t float freely, or doesn’t return to center
  • Debris washes back out of the skimmer when the pump turns off
  • Reduced skimming action or erratic surface draw

Maintenance Tips

  • Rinse the skimmer basket regularly—restricted flow can cause the weir to chatter or stick.
  • Keep the hinge/pivot area free of grit and calcium buildup so the door swings freely.
  • If the weir sticks, inspect for warping or swelling and confirm the pin spacing matches your skimmer body.
  • Maintain the pool water level near mid-skimmer opening for best surface skimming performance.
