Your pool pump is the most essential equipment in your pool system. When it runs smoothly, everything else follows. But when it starts acting up, it can be a major headache if ignored. Let's break down some of the most common pool pump problems and how to tackle them.
1. No Flow
What it means: The pump is on, but no water is circulating through the system.
Likely causes:
-
Clogged pump basket or skimmer basket
-
Air leaks in the suction line
-
Closed or blocked valves
-
A dirty or clogged filter
-
Loss of prime (pump is full of air, not water)
What to do:
-
Turn off the pump and check for obstructions in the baskets.
-
Inspect and tighten fittings and o-rings on the suction side.
-
Make sure valves are open and lines are free of debris.
-
Clean or backwash the filter.
-
Re-prime the pump by filling the strainer basket with water before restarting.
2. Low Flow
What it means: Water is moving, but not as forcefully as it should.
Likely causes:
-
Partial clogs in the plumbing
-
Dirty filter or pump impeller
-
Air leaks
-
Worn-out pump components
What to do:
-
Check the filter pressure gauge. If it's high, clean the filter.
-
If the impeller is clogged, you may need to disassemble the pump to clean it.
-
Inspect for air leaks around the lid or suction fittings.
-
If your pump is aging, consider upgrading to a newer, energy-efficient model available at PoolPartsToGo.com.
3. Leaking Pump
What it means: You see water dripping or pooling under the pump.
Likely causes:
-
Worn shaft seal
-
Cracked pump housing
-
Loose fittings or unions
What to do:
-
Replace the shaft seal (a common wear item).
-
Inspect the housing for visible cracks.
-
Tighten or reseal any loose fittings.
-
If the leak is significant, it might be time for a replacement pump.
4. Noisy Operation
What it means: Your pump makes grinding, screeching, or rattling noises.
Likely causes:
-
Worn motor bearings
-
Cavitation (caused by air in the system)
-
Debris in the impeller
-
Vibrating due to poor installation or a loose base
What to do:
-
Listen closely to locate the source of the noise.
-
Check for air leaks and re-prime if necessary.
-
Clean the impeller.
-
If bearings are worn, replacing the motor or the entire pump may be cheaper.
Pro Tip:
Regular maintenance is the best way to prevent these issues. Clean baskets weekly, check water levels, and inspect fittings monthly. When in doubt, consult a pool professional or check out the helpful resources and replacement parts at PoolPartsToGo.com.
By staying ahead of common pool pump problems, you can enjoy a clean, clear pool all season long, without the headaches.
