As a leading manufacturer with over 25 years of experience in the filtration industry, Anping County Boli Hardware Wiremesh Products Factory is proud to introduce our Compact 13-Inch Pool Sand Filter for Above-Ground Pools, complete with a 1 HP pump and 20 GPM flow rate. This system is engineered to deliver crystal-clear water with minimal maintenance, making it the ideal solution for residential above-ground pools up to 15,000 gallons.

Below we break down the key features, specifications, and benefits of this complete filtration package.
Key Features & Benefits
- Compact Design – The 13-inch tank occupies minimal space, making it perfect for smaller backyards or above-ground pool setups. Despite its size, it provides efficient filtration for pools up to 15,000 gallons.
- High-Performance 1 HP Pump – The pump is self-priming and features a strainer basket to trap large debris before it reaches the filter. It operates quietly and delivers consistent water flow (20 GPM) for optimal turnover.
- Durable Construction – Tank is made from heavy-duty, UV-resistant engineering plastic (or optional stainless steel) to withstand outdoor conditions. The pump housing is reinforced thermoplastic for long life.
- Easy Maintenance – Sand filtration requires only backwashing every 2-4 weeks, depending on usage. No cartridges to replace – just rinse and reuse the sand for years.
- Universal Compatibility – Standard 1.5-inch inlet/outlet connections fit most above-ground pool plumbing kits. Includes all necessary hoses, valves, and mounting hardware.
- Energy Efficiency – The 1 HP motor is designed to maximize flow while minimizing electricity consumption, helping you save on utility bills.

Frequently Asked Questions
Q1: What type of sand should I use in this filter?
A: We recommend #20 silica sand (0.45–0.55 mm). You can also use alternative media like glass filter media or zeolite, which are compatible with the system.
Q2: How often do I need to backwash the filter?
A: Backwashing is typically needed every 2–4 weeks, depending on pool usage and debris load. When the pressure gauge reads 8–10 psi above the starting pressure, it's time to backwash.
Q3: Can this filter be used for in-ground pools?
A: This model is specifically designed for above-ground pools. For in-ground pools, we recommend our larger filter systems (e.g., 18-inch or 24-inch tank). Please contact us for recommendations.
Q4: Does the pump come with a cord and plug?
A: Yes, the pump is equipped with a 6-foot power cord with a standard 3-prong plug (115V). For 230V versions, a plug may be provided upon request. Please confirm voltage requirements when ordering.
Q5: What is the maximum head height of the pump?
A: The 1 HP pump can deliver up to 20 GPM at a head of approximately 25 feet (7.6 m). For higher lifts, a larger pump may be required.
Q6: Is the filter tank compatible with saltwater pools?
A: The standard plastic tank is resistant to low-level salt; however, for high-salt environments (e.g., salt chlorine generators), we recommend our upgraded stainless steel tank model. Please inquire about the saltwater version.
Q7: How long does the sand last before replacement?
A: With proper maintenance, #20 silica sand can last 3–5 years. Replace the sand when you notice reduced filtration efficiency or channeling.
Q8: What is the warranty and after-sales service?
A: We offer a 1-year warranty on the pump and a 2-year warranty on the filter tank against manufacturing defects. Our technical support team is available via email or chat to assist with installation and troubleshooting.
