Buying Guide
What to consider when choosing a sand filter pump for an above-ground pool:
- Pool size and desired turnover: Larger pools benefit from higher GPH and a powerful motor; smaller pools can run effectively with 1,500–2,100 GPH models.
- Valve versatility: A 6-way or 7-way valve simplifies maintenance, allowing Backwash, Rinse, and Waste functions without extra equipment.
- Timer features: A built-in programmable timer supports energy savings and consistent filtration cycles.
- Durability and materials: Look for corrosion-resistant tanks and motors designed for outdoor use; copper motors tend to be robust, but ensure warranty and compatibility.
- Installation and compatibility: Verify hose sizes and pool compatibility; some models are optimized for Intex systems, others are universal.
- Maintenance needs: Consider how easy it is to replace sand, backwash debris, and service the unit without specialized tools.
