Frequently Asked Questions (FAQ)
Q1: What size pool is this filter suitable for?
A: With a 20 GPM flow rate and 1.5 HP pump, this system is ideal for in-ground pools up to 15,000 gallons (approx. 30' x 15' pool). For larger pools, multiple units or a higher flow model may be required.
Q2: How often should I backwash the filter?
A: Backwash when the pressure gauge reading increases 8-10 PSI above the clean starting pressure. Typically, this occurs every 1-2 weeks depending on pool usage and debris load.
Q3: Can I use this filter with a saltwater pool?
A: Yes, the tank is made of corrosion-resistant thermoplastic. However, for saltwater pools, we recommend upgrading to a salt-resistant valve kit (available upon request) for maximum longevity.
Q4: What type of sand should I use, and how much?
A: Use #20 grade silica sand (0.45-0.55 mm). The tank requires approximately 150 lbs (68 kg). Do not use play sand or other types as they may damage the filter.
Q5: Does the pump come with a pre-filter strainer?
A: Yes, the pump includes a transparent strainer basket with a clear lid, allowing you to easily see and clean large debris before it reaches the filter.
Q6: Can I install this filter myself, or do I need a professional?
A: The top-mount design simplifies installation. With basic plumbing skills and tools, most homeowners can set it up. However, for complex plumbing or electrical connections, we recommend consulting a qualified pool technician.
Q7: What is the warranty period?
A: Our standard warranty covers the filter tank for 1 year against defects in materials and workmanship. Pump motor warranty is also 1 year. Extended warranty options are available upon request.
Q8: Do you offer custom voltage or plug types?
A: Yes, we can customize the motor for 220V/60Hz, 230V/50Hz, or other configurations. Please specify your requirements when ordering, and we will provide a suitable solution.
