FAQs
What is backflow and why is certification required for commercial properties in Cookeville?
Backflow is the unwanted reversal of water flow that can allow contaminants to enter the public drinking-water system. Cookeville, like all Tennessee cities, follows TDEC (Tennessee Department of Environment & Conservation) rules that mandate every commercial property with a potential cross-connection—such as fire sprinklers, irrigation systems, boilers, or chemical dispensers—to have an approved backflow prevention device. Annual certification by a state-licensed tester proves the device is installed correctly, functions as designed, and protects the city water supply from pollutants.
How often does my commercial backflow prevention device need to be tested?
Cookeville Water Quality Control requires most commercial backflow assemblies to be tested and re-certified every 12 months. Certain high-hazard sites—restaurants, medical offices, car washes, and industrial facilities—may receive reminders or compliance notices sooner if local inspectors deem the risk higher. If you repair, relocate, or replace the device, a new certification test is required immediately after the work is completed, even if it occurs before the next annual deadline.
What does the Cookeville city code require regarding backflow prevention for businesses?
City ordinance §18-204 adopts the Tennessee Cross-Connection Control Program. Key points include: • Installation of a USC-approved (University of Southern California) backflow prevention assembly on every service line deemed a moderate or high health hazard. • Registration of each device with the city and submission of a passing test report within 30 days of installation. • Annual recertification by a Tennessee-licensed backflow tester. • Immediate repair or replacement of any assembly that fails or is found to be improperly installed. • Non-compliance may result in fines or termination of water service until proof of certification is supplied.
What is involved in a commercial backflow certification test and how long does it take?
Our certified tester arrives with calibrated differential pressure gauges and reviews the device location for accessibility and code compliance. We shut off downstream water temporarily, record static line pressure, and perform the USC 10-step procedure (back-pressure/ back-siphonage checks, relief-valve opening point, and check-valve tightness). We clean or lubricate test cocks if needed and re-pressurize the system. The average single-device test takes 20–30 minutes; large campuses with multiple assemblies can take several hours. We restore water service immediately after each passing test.
What happens if my backflow device fails the test?
If the assembly does not meet minimum differential pressure or leaks during the test, our technician will explain the failure and provide a written estimate for repair or replacement. Many failures are corrected on the spot by cleaning debris from check valves or replacing worn rubber seats and springs. Once repaired, we re-test the device to verify compliance and then submit the passing report to Cookeville Water Quality Control. If repairs cannot be completed immediately, you will be given a temporary non-compliance notice; the city generally allows 10–14 days to achieve compliance before penalties apply.
How can I schedule a backflow certification with your plumbing company and what documentation will I receive?
Call our Cookeville office at (931) 555-BACK or use our online booking portal to choose a date and time.

A signed, stamped Backflow Test & Maintenance Report (original forwarded to the city; copy for your records). 2. A device tag indicating the test date, result, and next due date. 3. A digital inspection log with photos, pressure readings, and any repair notes. These documents satisfy city ordinance requirements and most insurance audits.
