Backflow Testing in Mississippi: Costs, Requirements & How to Find the Best Certified Testers
Mississippi is one of the few states where the health department licenses backflow assembly testers directly — the MSDH Bureau of Public Water Supply issues the credential. Mississippi also requires backflow prevention at ALL cross-connections, both high and low hazard, which is more comprehensive than most states.
Why Backflow Testing Matters in Mississippi
Mississippi State Department of Health (MSDH) Bureau of Public Water Supply licenses backflow assembly testers directly. Mississippi requires approved backflow prevention at all cross-connections — both high-hazard and low-hazard — a broader mandate than most U.S. states. Annual testing is required. Jackson’s water system, Biloxi, Gulfport, Hattiesburg, and dozens of rural water associations serve Mississippi’s population spread across its predominantly rural geography.

How Long Does Backflow Testing Take in Mississippi?
Standard tests: 25–40 minutes per assembly. Mississippi’s rural geography means testers may serve wide areas — confirm your tester’s service range before scheduling in outlying areas. All-hazard coverage means even low-hazard connections you might not expect to need testing may require annual inspection under Mississippi’s rules.
What to Expect on Test Day
Your tester arrives, locates your backflow assembly (typically near the water meter or service entrance), and connects calibrated differential pressure gauges to the test cocks. Water shuts off for 15–30 minutes during testing. You receive a signed test report immediately. Pass: results are filed with your utility. Fail: the tester identifies the fault and repairs or returns within the required compliance window. Always confirm your tester files results with your utility — request confirmation before they leave.
