• Single-speed pumps run at one constant speed and are often the least energy-efficient.
• Dual-speed pumps offer a high and low setting, allowing some energy savings.
• Variable-speed pumps allow full control of flow rate and are ENERGY STAR® rated, making them the most efficient and quietest option.

If you're looking to reduce energy bills and extend pump life, a is usually the best investment—and often qualifies for utility rebates.

Pump size is based on your pool or spa volume (in gallons) and the flow rate needed to turn over that volume in 8–10 hours. You'll also need to consider pipe size, filter type, and head pressure (the resistance in your plumbing system).

Oversizing can waste energy, while undersizing can lead to poor circulation and damage. If unsure, consult a pool professional or use a pump sizing calculator to determine the ideal fit.

In general, your pump should run 8–12 hours per day to ensure full water turnover and effective filtration. Variable-speed pumps can run longer at lower speeds, which improves efficiency and reduces noise while maintaining clean, balanced water.

Seasonal factors like water temperature, usage, and debris levels may require adjusting runtime accordingly.

Most pool and spa pumps last 5 to 7 years with proper maintenance. Signs it may be time to replace include:

• Loud or unusual noises
• Decreased water circulation
• Frequent motor failures
• High energy bills

If you're upgrading from a single-speed to a variable-speed model, you’ll likely see significant energy savings and better overall performance right away.
