Charlotte Water requires an approved tester. Any vendor on this list may test anywhere in Mecklenburg County. The PDF is sorted by company name; zip codes are for convenience, not a service-area limit.
Every company below is copied from Charlotte Water’s Approved Backflow Tester Company List, last updated 10/5/2026 12:02:12 p.m. This page is a local snapshot.
The PDF does not mark fire-line testers — no extra column, no icon, no red fill — so this page has no fire-line filter. Having “FIRE” in a name is not eligibility.
A trailing * on a company name is copied from the PDF, where it marks a Smart Irrigation Testing Company.
