Fleck 5600SXT 48,000 Grain Electronic Demand Deluxe Water Softener

Water softener for hard water in 3 to 5 person households with up to 4 bathrooms, Fleck 5600SXT 48,000 grain demand-regen valve with 1.5 cu ft of premium 10% crosslink Deluxe resin handling 5 to 30 grains per gallon hardness. Fleck 5600SXT 48,000 Grain Whole-House Water Softener with 10% Crosslink Resin and 18x33 Brine Tank An NSF/ANSI 61 certified whole-house salt-based water softener built for homes on hard city water or low-iron well water with 5 to 30 grains per gallon (gpg) of hardness, sized for 3 to 5 occupants and 2 to 4 bathrooms, using a Fleck 5600SXT digital metered control valve that only regenerates when soft water capacity is actually depleted (not on a fixed timer) and 1.5 cubic feet of premium 10% crosslink cation exchange resin that lasts roughly 12 to 15 years instead of the 8 to 10 years typical of standard 8% crosslink resin used by most competitors. Best For / Not For Use this 48,000 grain size if your household has 2 to 4 bathrooms, 3 to 5 occupants, and water hardness somewhere between 5 and 30 grains per gallon, on either municipal city water or low-iron well water (under 1 ppm dissolved iron). This is the most-sold middle-of-the-lineup size and is the right answer for the majority of homes with city water in the United States. Step up to the 64,000 grain size if your household has 4 to 6 bathrooms, 4 to 7 occupants, hardness between 15 and 50 gpg, or moderate hardness combined with iron in the water. Step up to the 80,000 grain size if your household has 5+ bathrooms, 6+ occupants, or extreme hardness above 25 gpg up to 80 gpg. Step down to the 32,000 grain size if your household has 1 to 2 bathrooms, 1 to 3 occupants, and hardness below 25 gpg. Not suitable as a standalone solution if your well water has more than 1 ppm dissolved iron, hydrogen sulfide (rotten egg smell), or pH below 6.5. In those cases an iron filter (Fleck 2510AIO with Katalox Light) or acid neutralizer must be installed BEFORE the softener so the softener resin is not damaged by iron fouling, sulfur, or acidic water.

Why This Softener vs Cheaper Timer-Based Softeners Eliminates calcium and magnesium hardness so soap actually lathers, dishes come out spot-free, laundry stays bright, and skin and hair feel softer, by exchanging the hardness ions for sodium ions on the 10% crosslink resin bed. Saves salt and saves water by only regenerating when soft water is actually depleted, using the Fleck 5600SXT digital metered demand-initiated regeneration valve that tracks gallons used (cheaper timer-based softeners regenerate every 3 days regardless of usage and waste hundreds of pounds of salt per year). Lasts 12 to 15 years on the resin instead of the 8 to 10 years typical of standard 8% crosslink resin, because the 10% crosslink polystyrene structure resists chlorine oxidation 20 to 30 percent better than the 8% crosslink found in most competing softeners. Critical for city water with chlorine or chloramine, helpful on any well too. Protects water heaters, dishwashers, washing machines, faucets, shower heads, and copper plumbing from scale buildup, which extends appliance lifespan by years and cuts energy bills (a scaled water heater uses 25 to 30 percent more energy). Removes up to 1 ppm of dissolved (ferrous) iron as a bonus, useful for low-iron city water or marginal well water, but not a substitute for a dedicated iron filter when iron exceeds 1 ppm. Includes the 1 inch stainless steel bypass valve pre-installed on the control head, so the softener can be isolated from house plumbing for service or salt refill without shutting off water to the rest of the home. Uses readily available standard salt (sodium chloride pellets or potassium chloride for low-sodium households) from any grocery store or hardware store, no proprietary cartridges, no chemicals, no annual service contracts.

The Fleck 5600SXT 48,000 grain unit eliminates the calcium and magnesium ions that cause every one of these symptoms. How Ion Exchange Softening Works (Plain English) Hard water enters the mineral tank from the top and flows down through the bed of 10% crosslink resin beads. Each resin bead carries thousands of negatively charged sites loaded with sodium ions. As the hard water passes through, the calcium and magnesium ions (positively charged, bigger and more strongly attracted than sodium) swap places with the sodium ions on the resin. The water leaves the bottom of the tank as soft water and is sent to the home. After approximately 1,000 to 2,000 gallons (depending on hardness), the resin is loaded with calcium and magnesium and the Fleck 5600SXT meter triggers a regeneration cycle: brine (concentrated salt water) is drawn from the brine tank and pulled through the resin bed in reverse, the high concentration of sodium displaces the captured calcium and magnesium back off the resin, the calcium and magnesium are flushed to the drain, and the resin is recharged with fresh sodium ions ready for the next service cycle. The cycle typically uses about 7 pounds of salt and 25 to 50 gallons of water and runs at 2 AM by default. Installation Overview The softener installs on the main cold water line where it enters the home, AFTER any iron filter or acid neutralizer if those are present (softener always goes last in the treatment train so it sees clean water and is not fouled by iron or sulfur). Required: a 1 inch (or 3/4 inch with adapters) feed line, a drain within 20 feet (floor drain, laundry sink, sump, or condensate pump), a standard 110V grounded outlet within 6 feet, and roughly 24 inches by 48 inches of floor space for the mineral tank plus another 18 by 33 inches for the brine tank. Most installations are completed by a homeowner with basic plumbing experience in 2 to 4 hours, or by any local plumber in under 2 hours. The system ships pre-loaded with resin so there is no media loading step at install. Ongoing Maintenance and Cost Add a 40 pound bag of softener salt (sodium chloride pellets, or potassium chloride for low-sodium households) to the brine tank every 4 to 8 weeks depending on water usage. That is the entire ongoing maintenance routine. There are no filter cartridges to replace, no media to swap, no chemicals to dose, no annual service visits required. Salt cost is approximately $8 per month at Walmart prices. Resin replacement is typically not required for 12 to 15 years on this 10% crosslink resin (versus 8 to 10 years on standard 8% crosslink). Power consumption is negligible (less than $5 per year). Water consumption per regeneration is 25 to 50 gallons. Warranty and Ongoing Support Fleck 5600SXT control valve carries a 5 year manufacturer warranty (Pentair). Mineral tank carries a 10 year structural warranty. Brine tank carries a 5 year warranty. NSF/ANSI 61 certified for safe potable water contact.

Frequently Asked Questions (Mined From Real Customer Calls and Emails) What size water softener do I need? Multiply household occupants by 75 (gallons per person per day) and multiply by your hardness in grains per gallon to get daily grains of hardness removal. Multiply by 7 for weekly capacity needed. The 48,000 grain unit comfortably handles 3 to 5 occupants at 5 to 30 gpg hardness, regenerating every 5 to 10 days. If you have 4+ bathrooms or 6+ occupants or hardness above 30 gpg, step up to the 64,000 or 80,000 grain unit. Free phone sizing consultation at 800-460-5810. Will this remove iron from my well water? It will handle up to 1 ppm of dissolved (clear water) iron as a bonus. Above 1 ppm of iron, or any oxidized (orange) iron, or any hydrogen sulfide (rotten egg smell), you must install a dedicated iron filter (Fleck 2510AIO with Katalox Light catalytic media) BEFORE the softener. Sending iron-heavy water through a softener fouls the resin within months and ruins the system. Why 10% crosslink resin instead of standard 8%? The 10% crosslink polystyrene structure has 25% more cross-bonding between polymer chains, which makes the resin physically stronger and significantly more resistant to chlorine oxidation. On chlorinated city water, standard 8% crosslink resin degrades in 8 to 10 years. The 10% crosslink resin in this system typically lasts 12 to 15 years. The upgrade adds about 30% to resin cost but doubles practical lifespan, which is why it is standard equipment on this softener. What is demand-initiated regeneration and why does it matter? Cheaper timer-based softeners regenerate on a fixed schedule (every 3 days, every 5 days, etc.) regardless of how much water you actually use. The Fleck 5600SXT measures water usage with a flow meter and only triggers a regeneration when the soft water capacity is depleted. A typical household saves $40 to $80 per year in salt and 3,000 to 6,000 gallons of water per year by going metered instead of timer-based. Is soft water safe to drink? Yes. The amount of sodium added per gallon is roughly equivalent to the sodium in two slices of white bread per gallon of water consumed, far below FDA "low sodium" thresholds. Households on strict low-sodium medical diets can use potassium chloride pellets instead of sodium chloride. Many homes also install a small reverse osmosis drinking water system at the kitchen sink for lowest possible mineral and sodium content in drinking water. How long until it ships? Free freight to all 48 contiguous states, typically ships within 1 to 3 business days from the warehouse, transit time 3 to 7 business days depending on destination. The system ships pre-loaded with resin, on a wooden pallet, with the bypass valve already installed on the control head and the resin already in the mineral tank. No assembly of the mineral tank is required at install. Do I need a plumber to install this? No. Most homeowners with basic plumbing experience install in 2 to 4 hours using SharkBite fittings, copper sweat, PEX, or PVC. Required tools are common: pipe cutter, wrench, Teflon tape. If hiring a plumber, the install is typically a 1 to 2 hour job at the standard hourly plumbing rate. Detailed install videos are available on the Mid Atlantic Water YouTube channel. Can I use this on city water? Yes. The 10% crosslink resin is specifically chosen for city water because it tolerates chlorine and chloramine far better than standard 8%. City water typically has 5 to 15 grains per gallon of hardness, well within this 48,000 grain unit's range. What happens during a power outage? The Fleck 5600SXT control valve has an internal capacitor that preserves all settings (time of day, regeneration schedule, capacity remaining) for up to 48 hours during a power outage. After 48 hours the time of day must be reset; all other settings persist indefinitely.
