Introduction
A fully functioning pool pump is the heart of your swimming pool’s circulation system. Without it, your pool water turns cloudy, algae blooms take hold, and chemical balance suffers. Whether you’re in Cape Town or the surrounding Western Cape areas, understanding common pool pump issues and how to fix them will save you time, money, and frustration.
At Pools Reno, we specialise in swimming pool repairs, installations, and maintenance, including fast, affordable pool pump services.

FAQ – Pool Pump Problems
Q: How long does a pool pump last?
A: On average, 6–10 years depending on maintenance and water chemistry.
Q: Is it safe to run a noisy pump?
A: No. A grinding or screeching noise can mean worn bearings, which can cause overheating or pump failure.
Q: Can I fix a leaking pump myself?
A: Minor leaks from o-rings can be DIY repairs, but seal or motor issues should be left to pros.
