Keep Your Above‑Ground Pool Pristine with the Intex SX1500 Sand Filter Pump
If you’re tired of constantly swapping out cartridge filters or watching debris swirl around in your pool, the Intex SX1500 Sand Filter Pump is here to revolutionize your maintenance routine. Engineered for above‑ground pools up to roughly 8,400 gallons, this compact yet powerful system delivers crystal‑clear water with minimal fuss. Below, we’ll dive into why sand filtration is superior, unpack the SX1500’s key features, walk you through installation, and share pro tips to keep your pool sparkling all season long.
Why Sand Filtration Beats Cartridge Systems
While cartridge filters trap particles in replaceable pleated media, sand filters use a bed of specially graded silica (or optional glass) to capture debris. Here’s why sand beats cartridges:
Less Frequent Maintenance: Backwash once every 1–2 weeks versus weekly cartridge cleanings.
Long‑Lasting Media: Filter sand typically lasts 3–5 years before replacement.
Fine‑Particle Removal: Captures dirt down to 20–40 microns for noticeably clearer water.
Eco‑Friendly Operation: No disposable cartridges—just rinse and reuse the same sand.

Installation Made Simple
Position the Unit:
Place on a flat, stable surface within 5 ft of pool fittings.
Ensure the pump is level to prevent air leaks.
Add Filter Media:
Remove the multiport valve assembly.
Carefully pour in 26 lb of no.20 silica sand (sold separately).
(Optional) Substitute up to 18.5 lb of glass bead media for finer filtration.
Reattach the valve, checking that the O‑ring is clean and lubricated.
Connect Hoses:
Attach one hose from the pool’s drain port to the pump INLET.
Attach the other from the pump OUTLET to the pool return.
Tighten clamps securely to avoid leaks.
Prime the Pump:
Fill the strainer basket with water, then seal the lid.
Open the air relief valve on top of the filter tank briefly to bleed out trapped air.
Initial Backwash & Rinse:
Set the valve to BACKWASH and run until discharge water is clear.
Switch to RINSE for 30 seconds to resettle the sand bed.
Finally, turn to FILTER to begin normal operation.
Power Up:
Plug into a GFCI‑protected outlet.
Use the built‑in 24‑hour timer to schedule 2–12 hour filtration cycles automatically.
Operation & Maintenance Tips
Daily Run Time: Aim for 6–8 hours during peak usage or hot weather.
Monitor Pressure Gauge: Backwash whenever pressure rises 8–10 psi above starting level.
Regular Backwashing: Every 1–2 weeks keeps the sand bed free of compacted debris.
Sand Replacement: Plan to swap out media every 3–5 years, or sooner if flow visibly declines.
Winterizing: Drain all water from the pump, hoses, and tank before freezing weather.
Pros & Cons
Pros:
Efficient Fine Filtration: Removes particles down to 20 microns for clear water.
Low‑Maintenance Media: Sand lasts multiple seasons with simple backwashing.
Versatile Valve Settings: Six‑function valve handles all filter tasks.
Programmable Timer: Automates cycles so you can “set and forget.”
Compact Footprint: Ideal for most above‑ground pool setups.
Cons:
Upfront Media Cost: Requires purchase of sand or glass beads (sold separately).
Heavier Setup: Sand adds weight, making relocation more involved.
Space Requirement: Needs a stable, level area near your pool equipment.
Periodic Deep Cleaning: Occasional manual sand replacement required.
Pro Tips for Peak Performance
Balance Chemicals First: Proper pH (7.2–7.6) and sanitizer levels reduce strain on the filter.
Use a Skimmer Sock: Captures leaves and large debris before they reach the pump.
Inspect Seals & Hoses: Replace worn O‑rings and cracked hoses to maintain suction.
Check Timer Settings: Align filtration cycles with cooler off‑peak electricity rates if possible.
