- Always match by part number, cover/frame diameter, and screw pattern before ordering.
- If your pool uses dual drains or a specific sump, confirm the cover’s rated flow and configuration requirements for your system.
When to Replace

- Missing/damaged frame (collar) or stripped fastener points
- Loose cover, rattling, or visible damage from cleaning tools or freeze conditions
- Renovation or compliance update where a new anti-vortex cover is required
Installation Notes
- Turn the pump off before servicing any suction outlet cover.
- Clean the seating surface so the cover sits flush with no debris trapped underneath.
- Use the correct fasteners for your drain body and tighten evenly (do not overtighten).
- After installation, confirm the cover is secure and cannot be rotated/rocked by hand.

Maintenance Tip
Inspect suction outlet covers at least once per season for cracks, brittleness, or loosening fasteners. Replace immediately if the cover is damaged or no longer sits flat—small defects can worsen quickly and lead to unsafe conditions or unwanted debris entry.
