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 7/7/2026 3:02:36 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.
