What customers say
The WhisperFlo® VST Variable Speed Pool Pump by Pentair consistently garners overwhelmingly positive sentiment from its user base, establishing itself as a top-tier choice for pool owners seeking efficiency and performance. A recurring theme in customer feedback is the dramatic reduction in electricity consumption, with many users reporting significant savings on their utility bills, often justifying the initial investment within a few seasons. This energy efficiency is undoubtedly the product's most celebrated feature. Beyond the financial benefits, the pump's remarkably quiet operation is another standout attribute. Users frequently express delight at how silently the WhisperFlo® VST runs, especially at lower speeds, transforming the poolside environment into a more peaceful oasis compared to the often noisy single-speed alternatives. This quiet performance, coupled with its robust build quality, contributes significantly to overall customer satisfaction. While the initial purchase price is higher than traditional pumps, customers widely perceive the WhisperFlo® VST as an excellent long-term value due to its energy savings and extended lifespan. The ability to precisely control flow rates for various pool functions, from filtration to heating and cleaning, is also highly valued, offering a level of customization that enhances the overall pool ownership experience. Some users, particularly those less tech-savvy, occasionally mention a slight learning curve with the digital controls, but this is generally a minor point overshadowed by the pump's numerous advantages. Overall, the sentiment reflects a product that not only meets but often exceeds expectations, delivering on its promises of efficiency, quietness, and reliable performance.
Know before you buy
The WhisperFlo VST is designed as a direct drop-in replacement, which makes the physical installation straightforward if your plumbing matches the existing footprint. However, because this model involves electrical wiring and voltage configuration, we recommend hiring a licensed professional to ensure safety and code compliance.
The pump is versatile and supports a range from 115v to 230v. It will automatically adjust to the power supply provided, making it compatible with most standard pool electrical configurations.
Traditional single-speed pumps run at maximum capacity constantly, which is often more power than your pool requires. The VST allows you to program lower speeds for routine filtration, which significantly reduces energy consumption while still maintaining proper water circulation.
A TEFC motor is sealed off from the outside environment, preventing dust, moisture, and debris from entering the internal components. This design protects the motor from common causes of failure, leading to a more durable and longer-lasting pump compared to open-motor designs.
The interface is designed for simplicity, allowing you to easily set and adjust speeds based on your pool's specific needs. Once you program your preferred cycles, the pump handles the rest automatically.
