Pump will not prime; pump pot does not fill with water

Safety: Turn off power before opening the pump lid or adjusting valves.

• Fill pump with water: Remove the Sta‑Rite pump lid and fill the strainer housing completely with water. Lubricate the lid o‑ring with silicone lube and reinstall the lid tightly.
• Inspect lid o‑ring: Check for cracks, flattening, or dirt on the o‑ring. Clean or replace if needed.
• Check drain plugs: Verify that the winterizing drain plugs on the pump housing are installed with intact o‑rings and are snug.
• Tighten suction unions: Hand‑tighten unions on the suction side. Do not overtighten to the point of cracking.
• Look for visible leaks: With the pump running, observe the suction plumbing for air being drawn in (bubbles in lid, water drips when off). Repair cracked fittings or re‑seal threaded joints with appropriate thread sealant.
• Verify water level and valves: Ensure pool water level is high enough and that suction valves (skimmer/main drain) are open.
