Intex Krystal Clear Sand Filter Pump for Above-Ground Pools — 925 GPH, 6-Function Valve & 24-Hour Timer

The Intex Krystal Clear 925 GPH Sand Filter Pump is a compact sand-filtration system that circulates and cleans above-ground pool water with a 6-function valve, 24-hour timer, and HydroAERATION technology.

Designed for above-ground pools, this Intex sand filter pump combines a high-capacity 925 gallons-per-hour motor rating with sand media for long-lasting, low-maintenance filtration. The unit includes a multiport valve for easy mode switching, a built-in 24-hour timer for automated operation, and HydroAERATION technology intended to enhance circulation and surface water quality. Its durable construction and simple controls make it a practical choice for pool owners who want clear water with minimal daily attention.

How does the 6-function valve simplify pool maintenance?

The six-position multiport valve lets you select the right function quickly without disconnecting hoses or tools. Switching among modes is a single-handle action that streamlines common tasks like cleaning and winterizing.

• Filter: normal operation for water cleaning.
• Backwash: reverses flow to clean the sand bed.
• Rinse: clears debris after backwashing.
• Recirculate: bypasses the sand for fast mixing.
• Drain: removes water from the system for servicing.
• Close: isolates the pump for storage or repairs.

What performance can I expect from the 925 GPH rating?

The pump is rated at 925 gallons per hour (gph) at the pump port and an in-pool flow of approximately 550 gph, suitable for small- to medium-sized above-ground pools. Actual circulation depends on hose length, fittings, and pool resistance, but the pump balances strong throughput with energy-efficient operation.

• Rated flow: 925 gph motor capacity (3,501 L/h).
• Typical in-pool circulation: around 550 gph (2,081 L/h).
• Sand media: long-life filtration, usually up to five years between sand replacements with proper backwashing.

How does HydroAERATION technology affect water quality?

HydroAERATION by Intex introduces surface agitation and increased gas exchange to help improve clarity and perceived freshness. It encourages better circulation of oxygen at the water surface, which can complement filtration to produce clearer-looking water.

• Enhances surface circulation for improved skimming action.
• Promotes gas exchange and a cleaner surface film.
• Works alongside sand filtration for clearer water appearance.

How easy is routine upkeep and what is the expected maintenance schedule?

The sand system is low-maintenance compared with cartridge filters: sand typically lasts up to five years and cleaning is mainly backwashing. The built-in 24-hour timer simplifies run cycles, reducing guesswork and helping maintain consistent filtration without daily intervention.

• Backwash when pressure rises or every few weeks during heavy use.
• Replace sand approximately every 3–5 years depending on pool use.
• Use the 2–12 hour timer settings to automate daily filtration cycles.

Who is this for?

This Intex Krystal Clear sand filter pump is aimed at above-ground pool owners seeking a reliable, low-fuss filtration solution. It suits families, seasonal homeowners, or renters with medium-sized pools who want improved circulation, easy-to-use controls, and fewer routine interventions than cartridge systems. Choose this model if you value automated scheduling, simplified maintenance, and equipment designed specifically for above-ground installations.
