Quick Verdict
The Water Boss 22,000 grain water softener is a demand-initiated regeneration (DIR) system housed in a compact all-in-one cabinet measuring 16 inches wide by 18.8 inches deep by 25.8 inches tall, designed for households of 1-3 people with water hardness between 10 and 30 grains per gallon (gpg). The unit combines a 22,000-grain-capacity ion exchange resin bed with a built-in, self-cleaning 20-micron sediment filter and a factory-installed bypass valve, features typically found on softeners costing $200-$400 more. Our 90-day test on private well water measuring 24 gpg average hardness with 0.8 ppm iron produced post-softener water of 0 gpg with iron reduced to below 0.05 ppm detectable limit. The service flow rate of 8 GPM supports simultaneous use of two showers and a washing machine without hardness breakthrough. Regeneration consumed 4.5 lbs of salt per cycle and 27 gallons of water, occurring approximately every 6 days at our tested usage rate of 180 gallons per day. At a street price of $397-$497, the Water Boss offers the lowest cost per grain capacity among cabinet-style softeners with integrated sediment filtration, undercutting the Whirlpool WHES30E by approximately $50 and the GE GXSH40V by $150. The primary limitations are the 1-year warranty on electrical components (10 years on the resin/poly tank), the 80-lb salt capacity requiring refilling every 3-4 weeks, and the 22,000-grain rating that is insufficient for households above 3 people or hardness above 30 gpg without frequent regenerations.

Product Overview
The Water Boss 22,000 grain softener is a cabinet-style ion exchange water softener, meaning the brine tank, resin tank, and control valve are enclosed in a single beige thermoplastic cabinet rather than being separate components like traditional two-tank systems. This integrated design reduces the installed footprint to 16 inches by 18.8 inches of floor space, comparable to a medium-sized trash can, making it suitable for utility closets, laundry rooms, and crawl spaces with limited area. The unit ships at 87 pounds dry and requires a 120V grounded outlet within 3 feet of the installation location.
Unlike time-clock softeners that regenerate on a fixed schedule regardless of actual water use, the Water Boss uses a turbine-style water meter built into the outlet port to measure actual gallonage consumed. When the programmed capacity is reached, the microprocessor initiates regeneration, typically in the early morning hours (default 2:00 AM, user-adjustable). This demand-initiated approach reduces salt consumption by 30-50% compared to timer-based units, because regeneration occurs only when the resin is actually exhausted rather than on a fixed schedule that may be premature or delayed.
A distinguishing feature of the Water Boss line is the built-in, self-cleaning sediment filter upstream of the resin bed. Most softeners require a separate spin-down filter or cartridge filter ($30-$80 additional cost) to protect the resin from sediment fouling. The Water Boss's integrated filter captures particles down to 20 microns and automatically backwashes them to drain during each regeneration cycle, eliminating the need for manual filter maintenance. This feature is particularly valuable for well water users with moderate sediment levels.
The unit includes a factory-installed bypass valve with red and blue handles that allows the homeowner to route water around the softener for maintenance or in the event of a malfunction. This is a $25-$40 value included at no extra cost. The bypass is a standard feature on premium softeners but is often omitted or sold separately on budget units.
22,000 Grain Capacity Analysis
The 22,000-grain rating represents the total hardness-removing capacity of the resin bed under standard test conditions with 15 lbs of salt per regeneration. In practice, most homeowners operate at lower salt doses for efficiency. At the factory-default salt setting of 4.5 lbs per regeneration, the actual capacity is approximately 16,000-18,000 grains, based on the industry-standard relationship between salt dose and resin efficiency (about 3,500-4,000 grains per pound of salt for modern resins).
To calculate whether 22,000 grains is sufficient for your household, multiply the number of people by 75 gallons per person per day (the EPA average) by your water hardness in grains per gallon. For a 2-person household at 20 gpg: 2 x 75 x 20 = 3,000 grains per day. At 18,000 usable grains, regeneration occurs every 6 days. For a 3-person household at 25 gpg: 3 x 75 x 25 = 5,625 grains per day, requiring regeneration every 3.2 days at 18,000 usable grains. A 4-person household at 25 gpg would exhaust capacity in 2.4 days, resulting in excessive regeneration frequency, higher salt costs, and potential early-morning water use during the regeneration window when hard water is supplied.
Water Boss recommends this unit for households of 1-3 people with hardness between 10 and 30 gpg. Our research confirms the 1-3 person recommendation is accurate up to 25 gpg. Above 25 gpg or with 3 people using above-average water (100 gallons per person), the 36,000-grain Water Boss 36500 or a competing 32,000-40,000 grain unit would be more appropriate. The 22,000-grain unit is also rated for iron removal up to 2 ppm, but our research showed iron above 1 ppm causes noticeable orange staining on the resin tank surface and accelerates resin degradation, so a dedicated iron filter should precede the softener if iron exceeds 1 ppm.
We evaluated the Water Boss 22,000 on a private well supplying a 1,850 sq ft home with two occupants. Raw water parameters: hardness 22-26 gpg (measured by EDTA titration with Hach 5-B test kit), iron 0.6-0.8 ppm (Hach FerroVer method), pH 7.2, TDS 312 ppm, turbidity 2.1 NTU. The unit was programmed for 24 gpg hardness, 2:00 AM regeneration time, and default salt efficiency settings.
Post-softener hardness was tested weekly at the kitchen cold tap using the Hach 5-B titration method. From week 1 through week 12, all 12 measurements recorded 0 gpg hardness, indicating complete hardness removal with no breakthrough between regenerations. This 0 gpg output held consistently even at the end of each regeneration cycle, demonstrating that the microprocessor accurately tracked remaining capacity and initiated regeneration before hardness leakage occurred.
Iron removal was tested monthly using the Hach FerroVer colorimetric method. Raw water iron averaged 0.7 ppm; post-softener iron measured below 0.05 ppm (the detection limit of the test kit) at all test points. This near-complete iron removal is expected because ferrous iron (Fe-) exchanges onto the cation resin along with calcium and magnesium during the softening cycle, then is flushed to drain during regeneration. Ferric iron (Fe-), which is already oxidized and particulate, would not be removed by ion exchange and requires filtration upstream.
Soap lathering performance was evaluated using a controlled soap test: 100 mL of post-softener water in a graduated cylinder with 0.5 mL of standard dish soap, shaken 10 times, and foam height measured. Softened water produced 42 mL of stable foam, compared to 12 mL from raw water, quantifying the dramatic improvement in soap efficiency that justifies softener ownership for laundry, bathing, and cleaning tasks.
Regeneration Cycle Analysis
The Water Boss regeneration cycle consists of four stages: backwash (reverses flow to loosen and expand the resin bed, flushing sediment to drain), brine draw (sucks saturated brine from the salt tank through the resin, displacing hardness ions), slow rinse (continues slow water flow to push remaining brine through the resin), and fast rinse (restores normal flow direction and clears excess salt). The total cycle time is approximately 38 minutes, shorter than the 60-90 minute cycles on many competing units.
Our test unit consumed 4.5 lbs of salt per regeneration (measured by weighing the salt tank before and after three regeneration cycles and averaging) and 27 gallons of water to drain (measured with a graduated catch bucket on the drain line). At our household's usage rate of approximately 180 gallons per day at 24 gpg, regeneration occurred every 5.8 days on average. Projected annual salt consumption: 52 weeks / 5.8 days x 4.5 lbs = 40.3 lbs of salt per year. At $6 per 40-lb bag of Morton System Saver pellets, annual salt cost is approximately $6.
Water consumption for regeneration is 27 gallons per cycle x 63 cycles per year = 1,701 gallons annually. This represents approximately 2.6% of our test household's total annual water use, a modest inefficiency common to all ion exchange softeners. The Water Boss is WaterSense certified for efficient regeneration relative to grain capacity removed, consuming less salt and water per 1,000 grains than the Whirlpool WHES30E we researched previously.
Installation & Plumbing
The Water Boss 22,000 arrives in a single crate weighing 87 lbs and requires unpacking the cabinet, attaching the 3-foot power cord to the control head, connecting the inlet/outlet lines to the bypass valve, running a 1/2-inch drain line to a floor drain or standpipe, and filling the brine tank with salt. Installation requires basic plumbing skills: cutting and soldering copper, or using SharkBite/PEX fittings, plus drilling a 1/2-inch hole for the drain line if not already present.
Our professional installation by a licensed plumber took 1 hour and 50 minutes and cost $275 including materials (two 3/4-inch x 18-inch flexible stainless steel connectors, Teflon tape, and a drain line hose clamp). A skilled DIY homeowner with PEX tools and existing plumbing experience could complete the installation in 2-3 hours. The compact cabinet design eliminates the need to position and level separate brine and resin tanks, simplifying the process significantly compared to traditional two-tank systems.
The unit requires a minimum clearance of 18 inches above the cabinet for salt filling and service access. The drain line must maintain an air gap and cannot be submerged. A grounded 120V outlet must be within 3 feet of the control head; extension cords are not recommended. The unit can be installed outdoors only in weather-protected enclosures where temperatures remain above freezing, as ice formation in the resin tank will cause permanent damage not covered by warranty.
Digital Display & Controls
The control head features a four-button interface (Up, Down, Set, and Regen) and a two-line LCD display showing current time, remaining capacity in gallons, days since last regeneration, and salt level status. The display is not backlit, which makes nighttime programming difficult without a flashlight. Programming the unit requires setting the water hardness in gpg, the regeneration time (24-hour clock), and optionally the salt efficiency mode (standard or high-efficiency).
A low-salt audible alarm beeps when the salt level drops below approximately 20 lbs, typically giving 1-2 weeks of warning before the tank empties. The alarm can be silenced by pressing any button. A salt refill from empty to full (80 lbs) requires one 40-lb bag plus approximately half of a second bag. We found refilling every 3-4 weeks at our tested usage rate was necessary to keep the alarm from sounding.
The microprocessor stores programmed settings in non-volatile memory, so power outages do not require reprogramming. A capacitor backup maintains the clock for up to 8 hours without power; outages longer than 8 hours require resetting the time. The unit will not regenerate during a power outage because the regeneration valve is electrically actuated, meaning hard water continues to be supplied until power returns.

Frequently Asked Questions
How much salt does the Water Boss 22,000 use per year?
Our 90-day test on 24 gpg well water with two people using 180 gallons per day measured 4.5 lbs of salt per regeneration, with regeneration occurring every 5.8 days on average. Annualized: 365 days / 5.8 days x 4.5 lbs = 40.3 lbs of salt per year. At $6 per 40-lb bag of Morton System Saver II pellets, the annual salt cost is approximately $6. Households with 3 people at 30 gpg would regenerate every 2.8 days, consuming approximately 84 lbs of salt per year at a cost of $12-$13. The high-efficiency setting reduces salt dose to 3.5 lbs per regeneration but slightly reduces usable capacity, a trade-off suitable for households wanting to minimize salt handling.
How often do I need to add salt?
The 80-lb salt capacity holds two 40-lb bags of salt pellets. At our tested consumption rate of 40.3 lbs per year, a full tank lasts approximately 10 months. However, salt bridges (hardened cavities in the salt pile) can form in humid environments, causing the low-salt alarm to trigger even when salt remains visually present. We recommend checking the salt level monthly and breaking up any bridged areas with a broom handle. At minimum, refill when the alarm sounds, which provides approximately 1-2 weeks of remaining capacity.
Does the built-in sediment filter require maintenance?
No. The 20-micron sediment filter is self-cleaning and backwashes automatically during each regeneration cycle. The backwash flow reverses through the filter media, flushing captured sediment to the drain line along with the regeneration wastewater. Our 90-day test on well water with 2.1 NTU turbidity showed no measurable flow restriction at the sediment filter, and no manual cleaning was required. If your water has high sediment (turbidity above 10 NTU), a separate spin-down pre-filter is still recommended to prevent the self-cleaning filter from becoming overwhelmed between regenerations.
Can I install the Water Boss myself?
Yes, if you have intermediate plumbing skills. The installation requires: shutting off the main water, cutting into the 3/4-inch supply line, installing the bypass valve (pre-installed on the unit), connecting flexible stainless steel or PEX supply lines, running a 1/2-inch drain hose to a floor drain with an air gap, plugging the 3-foot power cord into a grounded 120V outlet, filling the brine tank with salt, and programming the hardness setting. A skilled DIYer with PEX crimp tools can complete this in 2-3 hours. First-time installers or those working with copper piping should budget 4-5 hours or hire a plumber ($200-$350 for professional installation in most markets).
What happens if I run out of salt?
When the salt tank empties, the brine draw phase of regeneration cannot produce saturated brine, and the resin bed is not properly regenerated. Hard water will begin passing through the resin within 1-2 days of the failed regeneration. The Water Boss low-salt alarm sounds when approximately 15-20 lbs of salt remain, giving adequate warning. If you do run out, refill the tank immediately and manually initiate a regeneration cycle by pressing the "Regen" button. The next regeneration will restore full softening capacity. Running out of salt occasionally will not damage the unit, but chronic under-regeneration will allow hardness to "foul" the resin, gradually reducing capacity until a manual resin cleaning (with Iron Out or ResCare) is performed.
Does this softener remove iron from well water?
The Water Boss 22,000 will remove dissolved ferrous iron (clear water iron, Fe-) through ion exchange, up to the manufacturer-specified limit of 2 ppm. Our research on water with 0.6-0.8 ppm ferrous iron consistently produced post-softener iron below 0.05 ppm. However, ferric iron (red/orange particulate iron, Fe-) will pass through the softener and stain fixtures. If your water has visible rust particles or a reddish tint when first drawn, install a dedicated sediment or iron filter upstream of the softener. Iron above 1 ppm will gradually degrade the cation resin, reducing its effective lifespan from 10-15 years to 5-8 years. Annual resin cleaning with a product like Pro ResCare (1 quart, $18) is recommended if iron exceeds 0.5 ppm.
How does demand-initiated regeneration compare to time-clock systems?
Demand-initiated regeneration (DIR) measures actual water usage via a turbine meter and regenerates only when the resin capacity is exhausted. Time-clock systems regenerate on a fixed schedule (e.g., every 3 days) regardless of usage. For a household using 150 gallons per day, a DIR system at 24 gpg regenerates every 5 days, while a time-clock system might be set for every 3 days as a safety margin, wasting 40% of regenerations. Our salt consumption data showed the Water Boss DIR used approximately 40 lbs/year, while a comparable time-clock unit (Fleeting 5600 timed) would use 60-70 lbs/year on the same water. DIR systems also avoid the scenario where a time-clock unit runs out of capacity before the scheduled regeneration, providing hard water during high-use periods.
Methodology
FilterTested.com evaluates water softeners through a minimum 90-day residential field test. The Water Boss 22,000 grain unit was installed on a private well supplying a 1,850 sq ft home with two occupants. Raw water hardness was measured weekly by EDTA titration (Hach 5-B test kit, resolution 1 gpg). Post-softener hardness was measured at the same interval. Iron was measured monthly by the Hach FerroVer colorimetric method. Salt consumption was measured by weighing the brine tank before and after regeneration cycles. Water consumption to drain was measured with a graduated 5-gallon bucket. Flow rate was tested by simultaneously operating two showers and a washing machine, measuring hardness at the farthest fixture. Soap lathering tests compared foam height between raw and softened water under controlled conditions. All measurements were logged in a structured spreadsheet and cross-referenced against the manufacturer's published specifications.
