What is Backflow and Why Is It Dangerous to Public Drinking Water?
Backflow is the reverse flow of contaminated water into clean public drinking water lines, often caused by pressure changes. It can introduce harmful pollutants like chemicals or bacteria, risking community health.
A cross-connection is any link between potable water and a contamination source (e.g., irrigation with fertilizer, hoses in chemical buckets). Testable backflow preventer devices are the most reliable protection—they block reverse flow and are testable annually to ensure they work.
Backflow, Cross-Connections, and the Best Protection Method
Testable backflow preventers (RPZ, DCVA, etc.) are the most effective way to protect public drinking water—they create a verifiable barrier against contamination from cross-connections.
Who tests backflows? Only approved, certified testers (BPATs or equivalent) can legally perform backflow testing and certification. Modern Plumbing and Backflow uses fully certified, approved testers for accurate, compliant results.
Why Annual Backflow Certifications Are Crucial for Protecting Public Drinking Water
Annual certification ensures backflow prevention devices are working properly—preventing contaminants from entering the public water supply and protecting entire communities.
Without regular testing, a faulty device can cause serious contamination risks. Certified annual backflow testing catches issues early, avoiding health hazards, boil-water notices, and fines.
Real-World Backflow Incidents: Lessons from Preventable Contaminations

Backflow Incidents in the Carolinas: Local Examples That Hit the News
These events have happened right here in North Carolina, showing the real risk to local drinking water:
Fire-fighting foam contaminates 40,000 taps (Charlotte-Mecklenburg, NC, 1997)
Fire truck backpressure pushed foam into the supply, causing boil-water notices. Proper hydrant backflow prevention could have stopped it.
Pesticide sucked into water lines (Hope Mills, NC, 1986):
Main break caused pesticide backflow, contaminating 23 homes. A backflow preventer on the hose would have prevented this.
X-ray chemicals in clinic water (Wilson, NC, 1993):
Submerged hose allowed chemicals to back-siphon. A simple vacuum breaker could have protected the supply.
Boiler chemicals in soft drinks (Unnamed NC city, 1974):
Leaking valve contaminated restaurant drinks for 300+ people. Annual testing would have caught the issue.
Similar risks exist in South Carolina—annual testing is critical in Greenville, Spartanburg, and surrounding areas.
Why Backflow Certification Is Required by Law
Backflow certification is legally required under the Safe Drinking Water Act and local cross-connection control programs to protect public water supplies.
In NC and SC, annual testing and reporting to municipalities (Raleigh, Durham, Cary, Greenville, Spartanburg, etc.) is mandatory. Non-compliance can lead to fines, shutoffs, or liability.
