# Pool Pumps: Everything You Need to Know

Your pool pump is the most critical piece of equipment. Choosing the right one impacts energy costs, water quality, and noise levels.

## Single-Speed Pumps

The oldest and cheapest option ($200-$500) but the most expensive to operate. Running a single-speed pump costs $60-$120/month in electricity. Many states are phasing them out under energy efficiency regulations.

## Variable-Speed Pumps

Variable-speed pumps ($800-$2,000) adjust motor speed based on need. Running at low speed for filtration uses 80% less energy than single-speed. Most homeowners save $500-$1,200/year on electricity - the pump pays for itself in 1-3 years.

Pro Tip

Variable-speed pumps are now required by law in many states for new installations and replacements. Check your local regulations.

## Sizing Your Pump

A pump must turn over your pool's entire volume in 6-8 hours. For a 15,000-gallon pool, you need a minimum flow rate of about 31 GPM. Oversized pumps waste energy; undersized pumps can't maintain water quality.

## Top Brands

Pentair IntelliFlo, Hayward TriStar VS, Jandy VS FloPro, and Sta-Rite IntelliPro are the market leaders. All offer excellent reliability and similar energy savings. Choose based on your existing equipment ecosystem for easiest integration.
