Myth: Treatment capacity claims always match a household's daily water usage needs
Choosing water treatment equipment for a large home requires understanding daily water demand. Government sampling in Johnson County’s aquifer 111ALVM found hardness levels ranging from 300 to 548 mg/L (median 337 mg/L) measured as calcium and magnesium combined. These concentrations suggest that a water softener designed for higher hardness removal capacity is appropriate. Houses with greater occupant numbers or water use should consider equipment sized for larger volumes to maintain effective softening performance.
Myth: Hardness enters water uniformly regardless of source depth or system type
The hardness levels detected in Johnson County's area aquifer wells were sampled at depths between 17 and 177 feet, showing that hardness concentrations can vary with well depth. Groundwater hardness arises naturally as water passes through soil and rock containing calcium and magnesium minerals. Variations in well construction and source type may influence hardness levels experienced at the tap, even within the same aquifer.
Myth: Sample depth or water source type doesn't affect homeowner expectations for hardness
Differences in sample depth from shallow to deep wells cause variability in hardness concentrations. While regional data from four separate wells provide a range, individual household water testing is necessary to identify precise hardness levels in a specific well or municipal supply. This variability means homeowners should not rely solely on area data to select treatment equipment but use it as a reference point.
Myth: Softening treated water results in no change at the tap other than improved taste
The water softening system designed for large homes reduces hardness minerals calcium and magnesium, which are responsible for scale buildup and reduced appliance lifespan. Treated water typically exhibits fewer mineral deposits on fixtures, improved soap performance, and less spotting on dishes and glassware. This system helps maintain plumbing and appliances by controlling scale formation associated with the measured hardness range in Johnson County.
Myth: Hard water symptoms always clearly indicate the need for treatment
Symptoms such as spots on faucets, soap scum, and scale buildup are common indicators of hard water, but they can also result from other sources like water chemistry or fixture materials. The government’s record from Johnson County shows detectable hardness but does not define a health concern or water safety issue. Homeowners should observe signs within their home and confirm with water testing to assess if treatment with a suitable system is warranted.
Myth: The maintenance requirements of a large-home water softening system are complex and frequent
The Fleck Hard Water — Large Home System ships ready to configure and requires routine attention to maintain optimal function. Maintenance includes periodic refilling of salt (if salt-based), checking system settings, and ensuring resin beds are working effectively. This rhythm is designed to accommodate high household demand efficiently without excessive upkeep, supporting reliable hardness reduction for large homes.
To precisely determine the hardness in your household water, order a certified laboratory water test measuring combined calcium and magnesium hardness. A test result comparable to the Johnson County aquifer median would confirm that a water softener sized for this hardness range, like the documented Fleck system, is appropriate for your large home’s needs.

Source: USGS groundwater sampling. Sampled 2017-08-28. These figures describe groundwater sampled in this area. They are not a test of any individual private well - only a test of that well can establish its own water.
On record: U.S. Geological Survey sampling of Hardness, Ca, Mg in the 111ALVM aquifer (Johnson County): 5 results from 4 wells, median 337.0 mg/L, range 300.0-548.0 mg/L; none above any federal threshold
