Single Speed vs Variable Speed Pool Pumps: What’s Best?
When it comes to choosing a pool pump, one of the biggest decisions is whether to go with a single speed or variable speed model. Both have their place in modern pool setups, but they serve different needs. This guide breaks down the pros and cons of each type and highlights the best models available today.

Which Type of Pool Pump Is Right for You?
Single-speed pumps are a simple and affordable option if you just want a reliable, plug-and-play setup. However, if you're looking for long-term energy savings, lower noise, and customizable performance, a variable speed pump is worth the investment. Consider your pool size, local energy rates, and how much control you want over your system.
