Key takeaways
- The Fleck 5600SXT comes in five sizes from 24,000 to 64,000 grains; GE's current GXSH45W is a single 45,000-grain unit (GE product page).
- Fleck: 5 years on the control valve and 10 on the tanks. GE: 1 year on the entire appliance, 3 on the electronic monitor, 10 on the resin tank.
- GE publishes 5,090 grains removed per lb of salt, above the 3,350 benchmark in the EPA WaterSense guide; QWT publishes no grains-per-lb figure for the 5600SXT.
- QWT states the 5600SXT uses about 12 gallons per regeneration; the EPA says a typical softener uses 20 to 70.
- GE rates the GXSH45W to 165 gpg of hardness and 3 ppm of clear-water iron; QWT lists no hardness or iron ceiling for the 5600SXT.
- Pentair's SXT manual gives the valve a minimum 48-hour clock backup during outages (Pentair Fleck SXT manual).
Fleck vs GE: which water softener is the better buy?
For a home that will keep its softener ten years or more, we favor the Fleck 5600SXT. It is a named, model-numbered Pentair Fleck control valve on a standard mineral-tank-plus-brine-tank layout, sold by Quality Water Treatment in five sizes, and its valve warranty runs five years against GE's one-year whole-unit term.
GE wins on upfront cost and features. The GXSH45W is $390 less than the smallest Fleck size as of October 2026, publishes detailed performance limits, and connects to the SmartHQ app for leak and low-salt alerts. For a small household on a tight budget, that is a fair trade.

How do Fleck and GE softeners compare side by side?
The table uses only figures each seller publishes: Quality Water Treatment for the Fleck system, GE Appliances for the GE. Blank specs say "not published" rather than a guess.

Which has more capacity, the Fleck or the GE?
The Fleck, because it is sold in five sizes up to 64,000 grains. At 10 gpg, a household of five or six can step up to the 48,000 or 64,000-grain unit, the range our sizing guide points that household toward. GE's largest current model with full specs is 45,000 grains; GE also lists a 35,000-grain GXSH35W and the 45,000-grain Profile PNPR45W.
GE gives firmer limits. The GXSH45W is rated to 165 gpg of hardness and 3 ppm of clear-water iron, and GE's older GXSH40V is rated to 8 ppm. QWT publishes no hardness or iron ceiling for the 5600SXT, which it positions for city water. For context, Nebraska Extension says softeners in general may remove 5 to 10 ppm of iron and manganese; check each maker's rating. Well owners with iron should look at the Fleck 2510SXT in our well water rankings.
On flow, GE states 9.5 gpm at a 15 psi drop through a 1" valve. QWT does not publish a 5600SXT flow figure in text, so we don't quote one; the system ships with a 3/4" plastic bypass. The Fleck's 10% crosslink resin is described by QWT as more chlorine resistant, which counts on chlorinated city water.
What do Fleck and GE softeners cost to run?
Salt is the bigger running cost, and GE is the only one with a published efficiency figure. At 5,090 grains per pound, four people using 75 gallons each a day at 10 gpg (the planning figures Penn State Extension uses) would need about 215 lb a year, or five to six 40 lb bags. QWT says the 5600SXT cuts salt use by up to 40% compared to outdated systems and is candid that it "still consumes more salt than high-efficiency upflow systems." Without a grains-per-pound figure for the Fleck, a direct salt comparison isn't possible.
Bags cost about $5 to $10 each for sodium chloride, per NDSU Extension, so the GE's estimated salt bill is roughly $27 to $54 a year at that usage. Water is the other line item: QWT states the 5600SXT uses about 12 gallons per regeneration, well under the EPA's 20 to 70 gallon typical range. GE does not publish a per-cycle water figure. QWT also sells an optional SST-60 resin upgrade it says can save up to 40% on salt and 60% on waste water.
Which is easier to service over the years?
The Fleck, on design. It is a separate valve, mineral tank and brine tank, so a worn valve can be serviced or swapped without replacing the tanks, and the valve model is printed on the listing. The Pentair SXT manual shows how adjustable that valve is: each regeneration step can be set from 0 to 199 minutes, and the control can run as an immediate meter, delayed meter or time clock.
GE lists its valve only as "1-inch NPT High Flow," and after the first year only the electronic monitor and resin tank stay under warranty. Neither maker publishes failure rates, so warranty length is the clearest durability signal on paper. For installation, QWT calls the 5600SXT a simple DIY job of about two hours with a bypass and pre-programmed meter included; both units need a drain line. Our installation guide walks through it.
How do Fleck vs GE warranties and prices compare?
The warranty gap is wider than the price gap. As of October 2026, the Fleck 5600SXT from Quality Water Treatment is $1,189 for 24,000 grains, $1,265.73 for 32,000, $1,327.55 for 40,000, $1,373.15 for 48,000 and $1,523.96 for 64,000, with a 6-month money-back guarantee. Current sizes are on the Fleck 5600SXT product page (sold by Quality Water Treatment, a store run by our team).
GE lists the GXSH45W at $799, the GXSH35W at $699 and the older GXSH40V at $569. Coverage: five years on the Fleck control valve and ten on its tanks, against one year on the entire GE appliance (parts and labor), three on the electronic monitor and ten on the resin tank.

Common questions
Is Fleck better than GE?
For long-term ownership, the Fleck 5600SXT has the stronger warranty (five years on the valve versus one year on the GE unit) and more sizes. GE is cheaper and has app features. The better pick depends on household size and how long you plan to keep it.
Who sells the Fleck 5600SXT compared here?
Quality Water Treatment, which describes itself as a Fleck / Pentair authorized dealer. It ships the system with a pre-programmed meter and resin pre-loaded in sizes up to 48,000 grains.
Does the GE softener have a Fleck valve?
GE does not name a third-party valve. It lists a "1-inch NPT High Flow" valve on the GXSH45W.
Which uses less salt, Fleck or GE?
GE publishes 5,090 grains per pound of salt; QWT publishes no grains-per-pound figure for the 5600SXT, so a like-for-like answer isn't possible. QWT does say the 5600SXT uses more salt than high-efficiency upflow designs such as the city version of the SoftPro Elite.
Can either handle well water with iron?
GE's GXSH45W handles up to 3 ppm of clear-water iron. The 5600SXT is positioned for city water with no iron rating published; for wells, see our iron and sulfur picks.
What happens to a Fleck SXT during a power cut?
Per Pentair's SXT manual, the clock holds for a minimum of 48 hours with the power off, and QWT lists a 48-hour capacitor backup on the 5600SXT.
How much water does each use per regeneration?
QWT states about 12 gallons per cycle for the 5600SXT. GE does not publish a per-cycle figure; the EPA puts a typical softener at 20 to 70 gallons.
How we put this page together
This comparison is based on Quality Water Treatment's Fleck 5600SXT product page, GE Appliances' GXSH45W and GXSH40V pages, Pentair's Fleck SXT service manual, EPA WaterSense's May 2026 buying guide, and Nebraska, Penn State and NDSU Extension publications, all read in October 2026. The salt estimate is our arithmetic from GE's rating and Penn State's planning figures. Not included: Fleck flow rates that QWT shows only inside an image, review counts or averages, compare-at pricing, owner forum posts, and lab work, since we did none.
