FAQs
What is a backflow prevention device and how does it protect my commercial property?
A backflow prevention device is a mechanical valve assembly that keeps contaminated water or chemicals from siphoning back into the municipal water supply. In commercial settings—restaurants, factories, medical offices, and multi-unit buildings—equipment such as boilers, irrigation systems, or chemical dispensers can create pressure imbalances. Without a backflow preventer, those imbalances can pull polluted water into the potable lines, threatening public health and exposing your business to fines and liability claims.
Does Maynardville require commercial properties to have backflow preventers, and what are the consequences of non-compliance?
Yes. Maynardville follows Tennessee Department of Environment & Conservation (TDEC) Rule 0400-45-01-.17 and local utility ordinances, which mandate approved backflow prevention on any commercial service with a potential cross-connection hazard. If your property lacks a certified device or an up-to-date test report, the city can issue written notices, levy fines, or in extreme cases disconnect your water service until compliance is proven. Insurance carriers may also deny coverage for contamination incidents tied to unprotected service lines.
How often should my commercial backflow device be tested, and who can perform the test in Maynardville?
State and local code demand annual testing for all commercial backflow assemblies. The test must be completed by a Tennessee-licensed Backflow Prevention Assembly Tester (BPAT) who carries calibrated test equipment and submits the official report to the Maynardville Water Department within 10 days. Newly installed or repaired devices must be tested immediately after work is completed.
What are the common types of commercial backflow preventers and how do I know which one my building needs?
The three assemblies most frequently installed in Maynardville are: • Double Check Valve Assembly (DCVA) – For low-hazard uses such as fire sprinkler mains with no additives. • Reduced Pressure Zone Assembly (RPZA) – For high-hazard conditions like chemical processors, medical labs, or food-service soda systems. • Pressure Vacuum Breaker (PVB) – For irrigation lines that sit downstream from the main service. Selection is driven by the degree of hazard, line size, water pressure, and installation location. During a site survey, our certified technicians evaluate your plumbing layout, cross-connection risks, and local code to specify the correct assembly.
What warning signs indicate my backflow device is failing or needs maintenance?
Common red flags include: visible leaks from relief ports, unexplained drops in water pressure, water hammer noises when fixtures shut off, or water seeping out of test cocks. In RPZAs you may see continuous discharge from the relief valve—a sign of fouled check valves or debris under seats. If any of these occur, schedule inspection immediately; small leaks can escalate to full device failure and code violations.
