A booster pump is one of the most misunderstood components of a pool system. Many homeowners ask, “Do I really need one?” The answer depends on your pool’s design, features, and cleaning system. In this guide, we break down everything you need to know about pool booster pumps—especially for pools in Cape Town’s diverse residential setups.
What Is a Booster Pump for a Pool?
A booster pump is an auxiliary pump installed alongside your primary pool pump. Its main role is to deliver extra water pressure for specific pool equipment—most commonly pressure-side pool cleaners like the Polaris 280 or 3900.
Unlike your main pump that circulates and filters water, a booster pump gives an added “boost” to power high-pressure pool cleaners or water features.
When Do You Need a Booster Pump?
You may need a booster pump if:
- You use a pressure-side pool cleaner (e.g., Polaris or Pentair).
- You’ve installed high-head water features, fountains, or spa jets.
- Your pool design includes long plumbing runs or elevation changes.
Cape Town Use Case:
In sloped suburbs like Durbanville or Constantia, a booster pump may help overcome elevation and deliver consistent pressure.
Benefits of a Booster Pump
- Improved Cleaning Performance: Ensures your pressure-side cleaner works at optimal power.
- Efficiency: Lets the main pump focus on filtration while the booster pump handles cleaning.
- Longer Equipment Life: Reduces strain on your main pool pump.
How Booster Pumps Work
Booster pumps are typically installed on a dedicated pressure line. They run in tandem with your main pool pump and require a timer or manual switch to operate.
For energy efficiency, many pool owners use variable-speed models or install timers to run the booster pump only during cleaning cycles.
