Buying Guide: Key Purchase Considerations
- Pool size and water volume: Match the filter rating with your inground pool’s gallons and turnover rate to maintain clear water efficiently.
- Valve type and compatibility: Ensure the 6-way or 7-way valve (Filter, Backwash, Rinse, Waste, Recirculate, Closed, etc.) aligns with your existing pump and plumbing.
- Filter diameter and sand capacity: Larger diameters (24–30 inches) offer higher filtration area, improving flow and backwashing effectiveness for big pools.
- Material durability: Look for corrosion-resistant components and sturdy bases for long-term operation in outdoor environments.
- Installation footprint: Confirm space, piping connections (1.5″ or other), and mounting orientation (top-mount vs side-mount) fit your setup.
- Control features: Timers and automatic features can reduce maintenance and energy use, especially for large or busy pools.
- Maintenance and serviceability: Access to replacement sand, top valves, and service manuals influences long-term costs and downtime.
- Warranty and support: A strong warranty and accessible customer support help address issues quickly.
Overall, the best pick depends on your pool size, existing equipment, and preferred maintenance workflow.
