Hard water is the most common reason well owners call a treatment pro. Penn State Extension classes water above 7 grains per gallon (about 120 mg/L) as hard and above 10.5 gpg as very hard. In Parker County, TX, the median Trinity aquifer well sample in the state database is about 240 mg/L. A softener swaps calcium and magnesium for sodium (or potassium) on a resin bed and recharges itself with salt brine.
Size matters more than brand. An undersized unit regenerates constantly and burns salt. An oversized one costs more up front. Our calculator sizes the unit in grains from your household and test results. It then shows Angi's 2026 price range for that capacity, with labor listed separately.

Water Softener Installation FAQs
What size softener do I need?
People × gallons per day × hardness (gpg) × days between regenerations. Angi's family-of-four example at 10 gpg comes to 25,200 grains a week, which is a 32,000-grain unit.
Can a softener remove iron?
Some, but HomeGuide advises a dedicated iron filter ahead of the softener above about 1–2 ppm. NDSU puts the upper limit for standard softeners at about 10 ppm.
Will a softener hurt my septic system?
Each regeneration discharges about 50 gallons (Penn State). Ask your installer about the drain location and the regeneration settings.
How much does salt cost?
$40–$120 a year (Angi), or $5–$10 per 40-lb bag.
