What It Means
Pump Won't Prime
Likely Causes
- Clogged strainer basket
- Air leak at pump lid O-ring or suction fittings
- Suction valve partially or fully closed
Next Checks
- Remove and clean strainer basket
- Inspect pump lid O-ring — lubricate with Teflon-compatible silicone lube (never petroleum-based)
- Fill pump basket manually with water before restarting to assist initial prime
- Check all suction-side fittings and unions for air leaks
