Prevent Pool Flow Issues With This Simple Pool Pump Repair
If your pool pump is running but the water flow is weak or completely blocked, there’s a high chance your pool pump impeller is clogged. A dirty or blocked impeller can significantly reduce your pool’s circulation, making your filtration system inefficient and risking damage to your swimming pool equipment.
In this guide, we’ll show you how to clean your pool pump impeller safely and effectively—plus when to call in a pro for more advanced pool pump repairs or system installations in Cape Town and surrounding areas.
What Is a Pool Pump Impeller?
The impeller is a small, fan-like component inside your pool pump housing that pulls water through the system. Over time, debris like leaves, hair, or dirt can get lodged in the impeller vanes, reducing or completely stopping water flow.
Symptoms of a clogged impeller include:
- Weak water return to the pool
- Unusual pump noise (like grinding or humming)
- Pump motor overheating or shutting off
- Pool vacuum not working properly
Regular cleaning is essential to maintain optimal pump performance and extend the life of your pool system.
What You’ll Need
- Flat-head screwdriver
- Needle-nose pliers or tweezers
- Garden hose or soft-bristle brush
- Insulated gloves (for safety)
- Silicone lubricant (optional)
Step-by-Step: How to Clean a Pool Pump Impeller
Step 1: Turn Off All Power
Safety first. Shut off power at the circuit breaker to avoid electric shock. Never open your pump housing while the system is powered.
Step 2: Remove Pump Lid and Basket
Unscrew the pump lid and take out the pump strainer basket. Clean the basket thoroughly and check for large debris. Sometimes, a clogged basket may cause similar symptoms as a clogged impeller.
Step 3: Access the Impeller
With the basket out, reach your fingers or use pliers through the inlet port behind the basket. Gently feel for debris inside the impeller vanes. If you encounter resistance or feel something soft or stringy, you’ve likely found the blockage.
Step 4: Remove the Debris
Use needle-nose pliers or tweezers to gently pull out debris like leaves, hair, or string. Avoid forcing it—you don’t want to damage the impeller blades.
You can also flush the impeller using a garden hose or carefully scrub it using a soft brush. For stubborn build-up, apply a small amount of silicone lubricant to help release grime.
Step 5: Reassemble and Test
Once clean, reinsert the pump basket, screw the lid back on, and restore power. Watch your water flow return to normal!
