What each does
| Softener | Filter | |
|---|---|---|
| Removes | Calcium and magnesium | Iron, sulfur, chlorine or chloramine, taste and odor, depending on media |
| On a Ranches well | Often needed | Often needed, before the softener |
| On Sunrise water | Rarely needed | Common, for chloramine |
Why well homes often need both
Untreated Biscayne Aquifer water is hard, which is why the utilities around the Town soften theirs. It can also carry iron and hydrogen sulfide. A softener handles hardness; it is not designed to handle heavy iron or sulfur, which can foul its resin. So the usual sequence is iron and sulfur filtration first, softening second, and a drinking water stage at the kitchen.
Hydrogen sulfide also tends to come back as a smell in the hot water if it is not removed before the heater, which is another reason the filter stage comes first.
Match the symptom to the tool
- Orange stains: iron, so an iron filter. See orange stains.
- Rotten-egg smell in hot and cold water: hydrogen sulfide, so a sulfur filter or aeration. See sulfur smell.
- White crust and spots: hardness, so a softener. See hard water spots.
- Pool-like smell on Sunrise water: chloramine, so a chloramine-rated filter.
Order matters
Buying a softener first and adding iron treatment later is a common and expensive mistake on well water. Plan the whole sequence from one test, even if you install it in steps. Living Water configures a well water system that way.
Utility-water homes
If you are among the properties on City of Sunrise water, the plant has already softened it. The general logic for city water is in softener vs. filter: which do you need.
Some properties have utility water at the house and a well for the land. In that case, the house may need only a chloramine filter while the irrigation well gets an iron filter. Testing both tells you.
A typical well sequence
- Sediment or pre-filtration if the test shows particles.
- Iron and sulfur treatment.
- Softening.
- Drinking water stage at the kitchen.
Not every well needs every stage. The test decides which ones apply.
