Intex Krystal Clear Sand Filter Pump SX2800
Intex

What we like
- Sand media lasts up to 5 years with regular backwashing
- Genuine 6-function control valve simplifies backwashing and maintenance
- 24-hour timer with 2 to 12 hour preset cycles
- Widely available Intex parts and media
Worth knowing
- Heavier and bulkier than a cartridge unit (43 lb)
- Backwashing discharges pool water
- Tops out at 17,200 gallons, so not for large pools
It covers the widest verified range of the above-ground picks (5,500 to 17,200 gallons), uses sand you clean by backwashing rather than rinsing a cartridge weekly, has a genuine 6-function valve, and the sand lasts up to five seasons. Nothing here is exotic, which is the point.
It tops out at 17,200 gallons, so a large above-ground pool needs the Hayward instead. Owner reports also flag occasional leakage or sand return on some units, and fitting it to non-Intex pools such as Bestway or Coleman can need adapters. These are owner-reported patterns, not a measured failure rate.
How this Fit Score was reached (7.9/10)
SourceManufacturer specification from the product's Amazon listing (model 26647EG / SX2800)
Input2,800 GPH pump flow, 2,150 GPH in-pool system flow, rated 46.6 GPM maximum
CalcAt the real in-pool flow of 2,150 GPH, a 15,000 gal pool turns over in 15,000 / 2,150 = 7.0 h, under 8 h, so mid-size is covered -> 8 band. Pump flow 2,800 GPH / 60 = 46.7 GPM matches the stated 46.6 GPM max.
RuleThis is a mathematical comparison using the manufacturer's rated flow, not a measured installation flow.
LimitRated flow is a manufacturer figure, not an independently measured flow rate. Real delivered flow drops with plumbing length, fitting size, elevation, and a loaded filter.
SourceManufacturer recommended pool capacity (Amazon listing)
Input5,500 to 17,200 gallons, above-ground
CalcCovers small through mid-size above-ground pools; tops out at 17,200 gal, near the top edge of the above-ground segment -> 8 band
Rule9 to 10: matches its target segment with headroom at the top of the range.
LimitFit is judged against a segment, not your exact pool. Confirm against your own gallons before buying.
SourceFilter type and manufacturer sand-life claim
InputSand media, 77 lb, cleaned by occasional backwashing via the 6-function valve; sand lasts up to 5 years
CalcSand backwash routine, low weekly effort -> 8 band
Rule8: sand, cleaned by occasional backwashing, low weekly effort.
LimitFrequency depends on bather load, debris, and climate. This is the method's typical case, not a measurement of your pool.
SourceIntex replacement parts documentation for model 26647EG
InputIntex currently lists 26647EG-specific replacement parts including the 6-way valve, O-rings, basket, and other components
CalcDocumented model-specific parts from the manufacturer -> 8 band
Rule9: major brand with wide, long-term parts support (for example Hayward).
LimitAvailability changes over time and by region. Check current stock before relying on it.
SourceCleaning method
InputSand system; backwashing discharges pool water
CalcBackwash discharges water -> 7 band
Rule9: cartridge, rinsed without discharging pool water.
LimitActual water use depends on how often and how long you backwash, and on local rules for discharge.
SourceManufacturer install description and form factor
InputCombo pump-and-filter; partial assembly, then hook up two 1.5 inch hoses and plug in
CalcNear plug-and-play combo -> 8 band
Rule8 to 9: combo unit, tool-free or near tool-free setup, easy to store off-season.
LimitSetup ease is partly subjective and depends on your experience and site.
