FAQs
What is backflow and why is testing required for commercial properties in Lookout Mountain?
Backflow is the unwanted reversal of water flow, which can allow contaminants from industrial equipment, chemical storage, or irrigation systems to enter the potable water supply. In Lookout Mountain, municipal codes require annual backflow testing for all commercial facilities to safeguard public health and maintain compliance with Tennessee Department of Environment & Conservation (TDEC) regulations.
How often does my business need to have its backflow preventer tested?
Local ordinance mandates that commercial backflow prevention assemblies be tested at least once every 12 months. High-risk facilities—such as hospitals, food-processing plants, and labs—may need semi-annual testing, as specified by the water utility’s cross-connection control program.
What certifications should my backflow tester have?
Lookout Mountain accepts test reports only from technicians who are State of Tennessee–certified in Cross-Connection Control and hold a current backflow tester license. Our plumbers carry full certification, calibrated gauge documentation, and general liability insurance, ensuring every test meets municipal and state requirements.
What does a commercial backflow test involve and how long does it take?
A standard test includes shutting off downstream valves, connecting calibrated differential gauges, checking pressure across each check valve and relief valve, and verifying that shutoff valves hold tight. For most commercial assemblies, the procedure takes 20–40 minutes; complex fire-line or 4"+ devices may require up to an hour.
Will water service be interrupted during testing?
Yes, the backflow assembly must be isolated briefly. We schedule tests during off-peak business hours or coordinate with facility managers to minimize downtime. For critical operations, we can install temporary bypass lines or perform after-hours service.
How much does commercial backflow testing cost in Lookout Mountain and what’s included?
Pricing starts at $95 for a single ¾"–1" device, with volume discounts for multiple units or campuses. The fee covers pre-test inspection, certified testing, completion of the official test report, electronic filing with the Lookout Mountain Water & Sewer Department, and a digital copy for your records. Any required repairs are quoted separately before work begins.
