FAQs
What is backflow and why is its prevention critical for commercial properties in Greenback?
Backflow is the undesirable reversal of water flow that can allow contaminated water, chemicals, or waste to enter the clean, potable water supply. In commercial settings—such as restaurants, manufacturing plants, or multi-tenant buildings—hazards like chemicals, grease, and industrial process water pose an even higher risk. Preventing backflow protects public health, keeps your facility compliant with local and state plumbing codes, and shields you from potential fines or business shutdowns due to water-quality violations.
Does Greenback require commercial buildings to install and test backflow prevention devices?
Yes. Both Tennessee state plumbing codes and local ordinances adopted by the City of Greenback mandate that any commercial property with potential cross-connections—irrigation systems, fire suppression lines, boilers, chemical dispensers, and similar fixtures—must install an approved backflow prevention assembly. These devices must also be tested annually by a certified tester, and the passing test report must be filed with the local water authority or health department to maintain compliance.
How often should my backflow prevention assembly be tested and who can perform the test?
Most commercial backflow preventers must be tested at least once every 12 months. Certain high-hazard applications (e.g., medical facilities or chemically treated boilers) may require semi-annual testing. Testing must be performed by a state-licensed backflow prevention tester equipped with calibrated test gauges. Our company holds current Tennessee certification and provides same-day electronic submission of test results to the local authority, ensuring you stay fully compliant.
What types of backflow prevention devices are commonly used in commercial plumbing?
The most frequently used devices include: • Reduced Pressure Zone (RPZ) Assemblies – required for high-hazard cross-connections such as chemical lines or medical equipment. • Double Check Valve Assemblies (DCVA) – suitable for moderate-hazard systems like commercial irrigation and fire sprinkler feeds without additives. • Pressure Vacuum Breakers (PVB) – often used on dedicated irrigation lines where continuous pressure is present. • Spill-Resistant Vacuum Breakers (SVB) – ideal for indoor installations where leakage must be minimized. We assess your exact hazard level, water pressure, and installation location to recommend the safest, code-approved device for your facility.
What warning signs indicate my backflow preventer needs repair or replacement?
Common red flags include: visible leaks or discharge from relief ports, sudden drops in downstream water pressure, unexpected water hammer noises, rust or corrosion on shutoff valves, test gauge ports that will not seal, and failed annual test results. If you observe any of these issues, call a certified backflow technician immediately. Operating with a compromised assembly can jeopardize water safety and violate local regulations.
