How to spot a water-test scam

The first: someone offers a "free water test," the test always finds a problem, and the visit ends with pressure to buy expensive equipment on the spot. The City of Clearwater issued a public warning in April 2026 about door-to-door "free water testing" and fake grant letters, and stated plainly that the city endorses no private water company. Polk County issued a similar warning about mailers offering a free inspection, noting the tactic tends to run: test your water, find a problem, then sell equipment you may not need.

The second, more serious pattern: someone posing as a government or utility employee to get inside your home. Hernando County issued a fraud alert on March 5, 2026, describing people going door-to-door claiming to be Utilities Department staff, asking to enter homes to "test water quality," without an official county badge or a marked county vehicle.

None of these automatically mean fraud, but more than one together is worth pausing on:

• No county or utility badge, and no marked vehicle, despite a claim of official affiliation
• Urgency — a price that's "only good today" or "if you sign right now"
• A reagent test that turns your water black, brown, or another dramatic color, paired with alarming language
• Any claim of being sent by the city, county, or a government agency
• Refusal to leave a written quote, or pressure to sign before you've had time to think it over

A real free water test should feel unremarkable: someone measures your water, explains what they found in plain language, and leaves you with a written quote you can take your time with. Our own free test is built exactly this way — no reagent scare demo, a written quote left behind, and the federal 3-business-day cancellation right explained up front, not buried in fine print.

Legitimate in-home sales are legal in Florida, and both the FTC's Cooling-Off Rule and Florida's home-solicitation law exist specifically to protect you when you do decide to buy something at home. The goal here isn't to say all door-to-door sales are scams — it's to help you spot the difference.

Don't let anyone into your home without verifying ID and, for a utility claim, a marked vehicle. Call your utility or county directly using a number you look up yourself, not one the visitor gives you. Report suspicious activity to your local utilities department, or to law enforcement if you feel unsafe.

Every claim above comes from an actual public warning issued by a city or county government, linked in the sources below — this isn't us inventing a threat to sell against it.
