Frequently Asked Questions
1. What size pool is this filter suitable for?
This 50 GPM sand filter with 1.5 HP pump is ideal for in-ground pools up to 20,000 gallons. For larger pools, consider a higher flow model or multiple units.
2. How often do I need to change the sand?
Silica sand typically lasts 3–5 years depending on usage and water quality. We recommend replacing it when you notice decreased filtration efficiency or after heavy algae treatment.
3. Is the pump self-priming?
Yes, the pump is self-priming up to 4 feet (1.2 m) above water level. For longer suction lines, a primed suction line is recommended.
4. Can I use this system with a saltwater pool?
Yes, the corrosion-resistant tank is suitable for saltwater pools. However, we recommend using a saltwater-compatible pump if available; our standard pump is also resistant to mild salt corrosion.
5. What does the max pressure of 40 PSI mean?
40 PSI is the maximum operating pressure the system can safely handle. Normal operating pressure is typically 15–25 PSI. If pressure exceeds 40 PSI, backwash the filter or check for blockages.
6. Do you provide installation instructions?
Yes, a detailed user manual is included with the unit. It covers setup, plumbing connections, electrical wiring, and maintenance. Video guides are also available upon request.
7. What is the warranty period?
We offer a 1-year limited warranty covering defects in materials and workmanship. Extended warranty options are available for an additional cost.
8. Can I order a sample before bulk purchase?
Absolutely. We accept sample orders for evaluation. Contact our sales team for pricing and shipping details.
