Why you can still see spots
Spots are what is left behind when water evaporates. Even softened water carries dissolved solids, and the city's 2025 report lists sodium at 53 ppm, which it attributes to saltwater intrusion and leaching from soil. Those minerals can leave faint marks on glass. True hardness scale, the crusty white buildup on faucets and showerheads, is mostly calcium and magnesium, and that is what a softener removes.
Signs that point to hardness
- Crusty white scale on aerators and showerheads.
- Scale inside kettles and coffee makers.
- Soap that does not lather well.
- A filmy feeling after rinsing.
If these are strong, especially on a private well, measure hardness. On city water here, they are less common because of the plant's softening.
Softener vs. salt-free conditioner
| Ion-exchange softener | Salt-free conditioner | |
|---|---|---|
| Removes hardness | Yes | No |
| Uses salt | Yes (or potassium) | No |
| Needs drain | Yes | Usually no |

Other fixes for spots
- Squeegee shower glass after use.
- Use a rinse aid in the dishwasher.
- Use RO water for coffee makers and kettles; see under-sink RO.
- Clean aerators periodically.
Where the spots come from in your home
Note where you see them. Spots only on the outside windows and car usually trace to sprinklers, often from an irrigation well. Spots on shower glass and dishes come from your tap water. Scale only in the water heater or on hot-side fixtures can reflect what heating does to dissolved minerals. Each of these leads to a different fix, and only one of them is a softener. Taking a photo of the worst spots before the visit helps Jorge connect what you see with what he measures.
Wells and businesses
Private wells in the area deliver untreated groundwater that can be noticeably hard. Businesses with water heaters, dishwashers and ice machines may soften for equipment protection even on city water. Living Water installs ion-exchange softening plants for both, sized from a test. See water softeners in Lake Worth Beach.
