How to Read Your Water Test Results (Florida Homeowner’s Guide)

Aug 22, 2026

When we test your water, you get a set of numbers — hardness, TDS, chlorine or chloramine, pH, iron and more. They’re not complicated once you know what each one means and why it matters for your home. Here’s a plain-English guide to reading your results.

Hardness (grains per gallon)

The big one in Florida. Hardness is the calcium and magnesium dissolved from our limestone aquifers. Roughly: 0–3 gpg is soft, 3–7 moderately hard, 7–10 hard, and 10+ very hard. Most Suncoast homes land in the hard to very-hard range. Higher hardness means more spotting, more scale and faster appliance wear — it’s what a water softener is built to remove.

TDS — Total Dissolved Solids

Everything dissolved in your water added up — minerals, salts, metals. It’s a general “how much stuff is in the water” number, often showing up as a taste or heavier mouthfeel. TDS alone doesn’t tell you what’s dissolved, but a high number is a flag to look closer. Reverse osmosis is what dramatically lowers TDS at your drinking tap.

Chlorine vs. chloramine

Your utility disinfects the water so it stays clean to your tap, and which disinfectant it uses matters a lot. Chlorine is easier to filter with standard carbon. Chloramine (chlorine + ammonia) lasts longer in the pipes and is much harder to remove — a basic carbon filter barely touches it. Much of our area is on chloramine, which is why the type of filter media matters. Our city-by-city guide shows which is common where you live.

pH

How acidic or basic the water is (7 is neutral). Low, acidic pH can be corrosive and slowly eat at pipes and fixtures; high pH can worsen scale. Most municipal water is kept near neutral, but wells vary — pH helps us pick the right equipment and materials.

Iron, manganese and the rotten-egg smell

Iron (common on wells and some city areas) causes orange/brown staining and eats into a softener’s capacity — even ~0.3 ppm is enough to stain, and it usually needs dedicated treatment. Manganese behaves like iron’s cousin, causing dark brown/black staining. And if your water smells like rotten eggs — especially on a well — that’s hydrogen sulfide, a treatment issue (usually air injection), not something you can scrub away at the tap.

Putting it together

No single number tells the whole story — it’s the combination that points to the right fix: high hardness → softener; chloramine plus taste/odor → catalytic-carbon filtration; iron/sulfur/manganese (often wells) → dedicated well treatment; want the cleanest drinking water → RO at the kitchen tap. Still deciding? Here’s whether you need a softener, RO, or both.

Why an in-home test beats a strip or a guess

Store-bought strips give rough hardness at best and miss chloramine, iron behavior and flow context entirely. When we test in your home, we measure the numbers that actually drive equipment choice, factor in your household, and show you the results on the spot — free, with no obligation. You walk away knowing exactly what’s in your water whether you buy anything or not.

Common questions

What’s a “normal” hardness for Florida?
Most Suncoast homes test hard to very hard (roughly 7–15+ gpg), but it varies by city and even by street — which is why a real test beats an average.

Is a high TDS number bad?
Not automatically — it depends what’s dissolved. It’s a signal to look closer, and RO is the tool that lowers it at your drinking tap.

Do I need a lab test?
For most homes, an in-home test covers what matters for choosing equipment. If a specific concern calls for an independent lab test, we’ll tell you (those may carry a charge).

Can you test my well?
Yes — well water has its own profile (iron, sulfur, hardness, pH), and we size treatment to those exact numbers.
