FAQs
What is backflow and why is prevention important for my Collegedale commercial property?
Backflow is the unwanted reversal of water flow within your plumbing system, allowing contaminated water to enter the potable supply. In a commercial setting—where chemicals, cleaners, irrigation fertilizers, or industrial processes are common—this cross-connection risk is much higher. Preventing backflow keeps your employees, customers, and the wider Collegedale community safe from waterborne illnesses and protects you from costly code violations or business interruptions.
What types of backflow prevention devices are required by Collegedale or Hamilton County codes?
Local and state plumbing codes refer to the International Plumbing Code (IPC) and Tennessee Department of Environment & Conservation (TDEC) rules. For most commercial buildings in Collegedale, reduced-pressure zone (RPZ) assemblies are required on domestic water services, while double-check valve assemblies (DCVAs) are typically acceptable on dedicated fire-sprinkler lines without chemical additives. Specialized equipment such as atmospheric vacuum breakers (AVBs) or pressure vacuum breakers (PVBs) may be mandated on irrigation systems. The exact specification depends on your building’s cross-connection hazards, so we always perform a site survey before recommending a device.
How often does my backflow preventer need to be tested and who is authorized to perform the test?
Hamilton County Water & Wastewater Treatment Authority (WWTA) requires annual certification of all commercial backflow assemblies. Only state-licensed, ASSE-certified backflow testers can perform the inspection and submit the electronic test report to the county. Our team meets these licensing requirements, carries calibrated test gauges, and files all paperwork on your behalf to ensure uninterrupted compliance.
What are the signs that my backflow preventer is failing or needs service?
Visible discharge of water from the relief port, sudden drops in downstream water pressure, unexplained changes in water taste or color, or leaks around shutoff valves can all indicate a malfunctioning backflow preventer. In fire-protection systems, false alarms or inability to maintain line pressure can also be a clue. If you notice any of these issues—or if the unit fails its annual test—call us immediately to avoid potential contamination and violation fees.
What is the process and expected downtime for installing or replacing a commercial backflow prevention device in Collegedale?
1. Site Evaluation: We review water service size, pressure, and hazard classification. 2. Permitting: We obtain any required plumbing permits and coordinate with WWTA for inspection scheduling. 3. Installation: Most 2" and smaller devices can be installed in 2–4 hours; larger RPZ vault installations may take one full day. We pre-assemble fittings to minimize water shut-off time, typically limiting downtime to 30–60 minutes for small services and 2–3 hours for large mains. 4. Testing & Certification: Immediately after installation, we conduct the initial performance test and file documentation. 5. Final Inspection: A county inspector may visit to verify code compliance, after which the line is returned to full service.
