Hayward SPX1070KHR Weir Assembly Kit

Part # SPX1070KHR — a replacement weir flap assembly kit designed for the Hayward SP1070/1071 series Skim-Master® in-ground pool skimmers. Includes the hinged flapper door, spring, and adhesive bumper pad to restore proper skimmer operation.

Key Features

• Complete replacement weir assembly for Hayward SP1070/1071 series skimmers.
• Spring-loaded hinged flap ensures proper skimming bladder position and improves surface debris capture.
• Includes adhesive rubber bumper pad to minimize noise and prevent direct plastic-to-plastic contact when flap closes.
• High-quality corrosion-resistant ABS plastic construction for pool environment durability.
• Simple drop-in installation with standard mounting screw; no heavy plumbing changes required.

Typical Applications

This weir assembly kit is ideal when the skimmer flapper is cracked, broken, stuck open or closed, or when the skimmer is allowing debris to pass over the flap or drawing air. Replacing the weir restores proper water skim and helps maintain debris capture at the waterline.

Installation & Compatibility Notes

Turn off pump circulation and relieve system suction before servicing the skimmer. Remove the old weir flap by unscrewing the hinge screw, clean the area around the hinge and mounting surface, and install the new weir assembly kit. Ensure the flap opens and closes freely, the adhesive bumper pad is firmly attached, and there is no metal, concrete or debris interference. Verify proper operation once the system is restarted.

Why Choose This Kit?

Using the Hayward SPX1070KHR ensures you restore the original manufacturer’s design for the skimmer weir function. Correct weir operation helps maintain surface skimming efficiency, prevents air draw into the system, and supports cleaner pool water by improving debris removal at the waterline.

Maintenance Tips

• Inspect the weir flap monthly for cracking, warping or hinge corrosion and replace sooner if damage is evident.
• Ensure the moutning screw remains tight and the bumper pad still adheres firmly—looseness or pad loss can lead to flap slamming or debris bypass.
• During renovation or resurfacing, check that the skimmer throat height and waterline have not changed and the weir flap still aligns correctly.
• In colder climates, ensure the flap is free to move and not frozen in place during seasonal start-up.
