Water Softener Maintenance: Salt & Settings

The five-minute monthly check

A healthy softener asks very little: glance at the brine tank once a month and keep it at least a third full of salt. While you are there, confirm the salt looks loose and granular rather than crusted into a solid mass, and check the floor around the unit for moisture. If the display shows the time and the next regeneration, confirm the clock is right — a softener regenerating at 2 p.m. instead of 2 a.m. will hand you hard water mid-shower. That is the whole routine most months.

What kind of salt should I use?

Pellets or solar crystals from any brand are fine; the practical difference between them is purity and price, not chemistry. Higher-purity pellet salt leaves less residue in the brine tank over the years, which means less cleaning. What matters more than the salt type is not letting the tank run empty and not overfilling it to the brim, which encourages bridging. Homes dealing with iron in their water can use salt with an iron-fighting additive, though real iron problems deserve real treatment.

What is a salt bridge, and why is my water suddenly hard?

A salt bridge is a hard crust that forms across the tank above the water line, leaving a hidden air gap underneath. The tank looks full, but the water below the bridge is not touching salt, so the brine gets weaker and the softener quietly stops softening. The tell is soap that stops lathering while the salt level never seems to drop. The fix is satisfying: break up the crust gently with a broom handle around the tank's edges, and the unit recovers on its next regeneration.

The failures that need a professional

Resin beads wear out after many years of Eastern Iowa hardness, and a unit that regenerates constantly or never quite delivers soft water may have a fouled or exhausted bed. Motorized valve heads stick, injectors clog with sediment, and iron-fouled resin needs chemical cleaning or replacement. If your softener is regenerating but the water stays hard after you have ruled out a salt bridge, that is diagnosis territory — the parts are specific and the settings interact.

Getting service without a replacement pitch

An aging softener is a favorite target for equipment-replacement sales calls. Often the honest fix is a cleaning, a valve part, or corrected settings for your actual measured hardness. Hanna services softeners across the Corridor with hourly, commission-free techs — the recommendation follows the diagnosis, and repairs carry our one-year workmanship warranty. If the resin truly is done and replacement is the economical call, you will hear the reasoning, not a script.
