Shallow Well Pump Sucking Air: Troubleshooting Guide

A 20-year-old Florida home's irrigation well pump draws air, runs for hours without watering, but holds prime when manually fed. Neighbors' wells work fine.

Likely Causes

• Worn Pump Impellers: Reduced ability to create suction.
• Suction Line Leak: A crack or hole above the water line draws air.
• Faulty Foot Valve: The check valve at the bottom of the suction line may not hold prime.

Recommended Action

Inspect the suction line for visible leaks. Pull the line to check the foot valve. Given the complexity, a professional pump service is advised. Additional resources at Irrigation Tutorials - Pumps.
