The short answer: the first thing Water CheatCode teaches — before a single piece of equipment — is the test. Hardness, iron, manganese, pH, TDS, chlorine or chloramine, hydrogen sulfide, nitrate, arsenic, bacteria. The water tells you what the problem is; the problem tells you the technology; the technology tells you the equipment; the equipment gets sized to the home. Reverse that order and you'll sell a softener to a house with an iron problem and eat the callback. Problem → test → technology → equipment → sizing. It's the golden rule of the whole Roadmap, and it starts here.
Pick your lane first
Step 1 has two halves. The first is a decision: are you adding water to a home-service business you already run, or starting a water company from scratch? It changes your first ninety days completely. A plumber or HVAC company adding water starts with existing customers and a tech who tests on every call; a from-scratch dealer starts with lead generation and the kitchen-table sale. Both lanes run the same test. If you haven't picked, read how to start a water treatment business — it lays out both.
What you test for, and what each one is telling you
Every in-home test kit and lab panel covers some version of this list. Here's what each result means in the homeowner's house.
Hardness — dissolved calcium and magnesium, measured in grains per gallon. It's the scale in the water heater, the spots on the glass, the crust on the showerhead, the dry skin. Not a health issue; a money issue. A softener's job.
Iron — the orange staining in the tub and toilet, the metallic taste, the ruined laundry. Comes in dissolved (clear water that stains later) and precipitated (already rust-colored) forms, and the form decides the treatment. Iron also fouls softener resin, which is why it gets handled before the softener.
Manganese — iron's cousin: black or brown staining, often alongside iron in well water. Treated by the same family of oxidizing media.
pH — acidity. Low pH water is aggressive: it eats copper plumbing (blue-green stains), pinholes pipes, and some media won't work outside their pH range. Fixed early, with calcite or corosex, before anything else.
TDS — total dissolved solids, read on a meter in ppm. A quick, visual, honest number that says how much is dissolved in the water. High TDS is a reverse-osmosis conversation at the kitchen sink.
Chlorine / chloramine — the city's disinfectant. Taste, smell, dry skin and hair — and chlorine above about 1 ppm oxidizes and destroys softener resin, so on city water carbon goes before the softener. Chloramine needs catalytic carbon; regular carbon barely touches it.
Hydrogen sulfide — the rotten-egg smell on well water. Oxidize it out with the iron, or catalytic carbon for mild cases.
Nitrate — fertilizer and agricultural runoff, a serious issue for infants. Nitrate-selective resin or RO.
Arsenic — naturally occurring in groundwater in a lot of the country. RO or activated alumina.
Bacteria — coliform and E. coli on well water. UV, last in the train, on already-clear water.
You don't need to memorize the chemistry. You need to know what each number means for the family at the sink, and which technology answers it. That's step 2.
The two tests: the city's report and the live tap
For a home on city water, you have something most reps never use: the utility's own annual water-quality report. Every community water system publishes one (the Consumer Confidence Report), listing exactly what was detected, the legal limit, and the health goal. It's public, it's free, and almost nobody reads it.
The Water CheatCode approach is to bring both into the kitchen: the city's report — their data, not your opinion — and a live test on their own tap. Show the report, run the test, and go quiet. Let the water speak; let the homeowner tell you it's a problem. That's problem awareness they generated themselves, and it's the foundation of the kitchen-table close in step 6. It's also what makes the Water Report ad play work in step 7.
For well water there's no city report, which is fine — the free in-home test is the strongest well-water angle there is. Test on-site for the basics; send a sample to a lab for the things a strip can't read (arsenic, nitrate, bacteria), especially before you spec a system.
The honesty rule
Only ever say what's literally in the report or on the test. "Detected" isn't "illegal," and you never imply anyone's sick. You're a guide reading the homeowner their own data. That's what builds the trust that closes — and it keeps you on the right side of the ad platforms and the law.
Why "test first" is the whole business
Skip the test and every downstream step is a guess: the wrong media, the wrong size, the wrong price, a presentation the homeowner can argue with, and a callback when the iron fouls the resin. Test first and every step gets easier: the equipment picks itself, the sizing has real numbers, the presentation is their own data, and the install works the first time.
It's also your best sales tool. A rep with a test kit isn't selling; they're diagnosing. Homeowners let diagnosticians in the door.
What you'll learn in the program

FAQ
What should a water treatment dealer test for?
Hardness, iron, manganese, pH, TDS, chlorine or chloramine, hydrogen sulfide, nitrate, arsenic and bacteria. The on-site kit handles hardness, iron, pH, TDS and chlorine; nitrate, arsenic and bacteria usually go to a lab, especially on well water and always before you spec a system.
Why test the water before recommending equipment?
Because the water decides the technology, the technology decides the equipment, and the equipment gets sized to the home. Picking equipment first means selling a softener to an iron problem, undersizing the system, or fouling the resin — and eating the callback. Problem → test → technology → equipment → sizing.
What is a Consumer Confidence Report?
The annual water-quality report every community water system is required to publish, listing each contaminant detected, the legal limit (MCL) and the health goal (MCLG). It's public and free, and bringing it to the kitchen table alongside a live tap test lets the homeowner see their own water data instead of your opinion.
How do you test well water?
Run the on-site kit for hardness, iron, manganese, pH, TDS and hydrogen sulfide, then send a sample to a certified lab for nitrate, arsenic and bacteria. Well water has no city report, so the in-home test is both the diagnosis and the strongest sales angle.
What's the difference between hardness and contaminants?
Hardness is dissolved calcium and magnesium — a scale, spotting and appliance-damage problem, not a health rule, fixed by a softener. Contaminants like lead, arsenic, nitrate and disinfection byproducts are health concerns, typically handled by RO at the point of use or targeted media. Most homes need both conversations.
