Installation Notes
- Turn the pump off before servicing any suction outlet cover.

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.
