Q: How long can pool pump run without water?
A: Pool pump should NEVER run without water. Damage timeline: 0-30 seconds minimal damage, 1-2 minutes seal damage begins, 2-5 minutes motor winding damage, 5+ minutes complete destruction likely. Even 30 seconds can damage seals. Water provides critical cooling and lubrication. Turn off immediately if no water flow detected.

Q: Why is my pool pump running but no water coming out?
A: Pump running without water output indicates: pump lost prime from low water level, clogged pump basket blocking flow, air leak on suction side, closed valves preventing water flow, blocked skimmer or main drain. TURN OFF PUMP IMMEDIATELY to prevent motor damage. Check water level first, then basket, then valves. Do not restart until flow restored.

Q: What causes pool pump to lose water?
A: Pump loses water from: low pool water level below skimmer, clogged pump basket restricting flow, air leaks in suction plumbing, closed or stuck valves, blocked skimmer weir or main drain, underground pipe damage. Texas heat increases evaporation to 3 inches per week. Daily water level checks essential during summer.

Q: How do I prevent my pool pump from running dry?
A: Prevent dry running: maintain water level 2/3 up skimmer opening, clean pump basket weekly, check for air leaks monthly, install automatic water leveler, add flow switch to shut off pump when no flow, monitor during high evaporation periods, fix leaks promptly, consider smart pump controls with protection.
