Hayward SPX1089K Weir Assembly
Part Number: SPX1089K
Description
This weir assembly is designed for the Hayward Dyna-Skim series above-ground skimmers. It acts as the floating flap that regulates surface water flow into the skimmer while helping prevent debris bypass.
Compatibility & Fitment
- Fits Hayward Dyna-Skim skimmer model SP1089 (and variants) where the original weir has worn, cracked or stuck.
- Dimensions approximately 7-7/16″ width × 5-3/8″ height—verify fitment with existing skimmer.
- Ideal for above-ground pools using the SP1089 skimmer body requiring a direct weir replacement.
Features & Specifications
- Includes the snap-in flap with bumper pad to help absorb impact and allow proper seating.
- Precise dimensions: ~7.5″ × 5.3″ × 1″ deep (approximate flange depth) for correct housing fit.
- Color: White (standard finish) unless a specialty-color variant is noted.
Installation Notes
Turn off circulation and reduce water flow so the skimmer is not generating suction. Remove the old weir by pulling straight out of the skimmer throat. Clean the cavity and check for warping of skimmer sidewalls, which may cause the flap to bind. Insert the new weir, ensuring the pins engage smoothly and that the flap moves freely without sticking. Resume flow and observe for proper skimming action without debris bypass.
Maintenance Tip
Inspect the weir each service visit. Replace if the flap is cracked, stained severely, or no longer floats well. Proper weir action helps maintain optimal skimming efficiency and reduces strain on the pool pump system.
