FAQs
What is a backflow-prevention assembly and why does my Church Hill business need one?
A backflow-prevention assembly is a mechanical valve system installed on your water service line to stop contaminated water from reversing direction and entering the public drinking supply. Commercial properties in Church Hill create higher risks—chemicals, cleaners, irrigation fertilisers, fire-sprinkler additives and industrial processes can all siphon back if pressure drops. State plumbing code and the City of Church Hill’s Cross-Connection Control Ordinance therefore require most businesses to install an approved assembly to protect the municipal water system and public health.
Which commercial properties in Church Hill are required by code to install backflow-prevention devices?
Local regulations mirror the International Plumbing Code (IPC) and Tennessee Department of Environment & Conservation (TDEC) rules. Any property with a potential cross-connection must have protection, including: • Restaurants, cafés and commercial kitchens • Manufacturing and chemical plants • Medical, dental, veterinary and laboratory facilities • Buildings with booster pumps, fire-sprinkler or irrigation systems • Multi-tenant buildings with separate water meters If you’re unsure, the Church Hill Water Department or a licensed cross-connection specialist can perform a site survey and tell you what level of protection (RPZ, DCVA, PVB, etc.) is mandated.
How often does a backflow-prevention assembly need to be tested, and who can perform the test?
Church Hill follows state guidelines that require annual testing for all Reduced-Pressure Zone (RPZ) and Double-Check Valve Assemblies (DCVA). Pressure Vacuum Breakers (PVB) tied to irrigation systems also need yearly verification before the system is put back in service. Only technicians certified in Backflow Prevention Assembly Testing (BPAT) by the state or local water authority may perform the test. After testing, they must file a signed report with the Church Hill Water Department within 10 days to keep your compliance record current.
What types of backflow-prevention assemblies are commonly installed in commercial plumbing systems?
1. Reduced-Pressure Zone (RPZ): Highest protection; required where chemical or high-hazard substances are present (e.g., commercial laundries, labs). 2. Double-Check Valve Assembly (DCVA): Medium protection for non-health hazards like fire-sprinkler loops without additives. 3. Pressure Vacuum Breaker (PVB): Used mainly on irrigation lines where the assembly can be installed above ground and downstream of the meter. 4. Spill-Resistant Vacuum Breaker (SVB): Similar to PVB but designed for indoor use. Your plumber will size and select the correct assembly based on hazard level, pipe diameter and available installation space.
What are common warning signs that my backflow-prevention device is failing?
• Continuous discharge or water leaking from the relief port (RPZ units) • Unusual pressure drops or fluctuations in your building’s water lines • Visible corrosion, rust or mineral buildup on the assembly • Difficulty closing shut-off valves or stuck test cocks • Failed annual test results If you notice any of these, call a licensed backflow plumber right away. Operating with a faulty device can contaminate the public supply and expose your business to fines or shutdown orders.
How much does installation and annual testing cost, and are there penalties for non-compliance in Church Hill?
Costs vary by pipe size and device type: • Installation: $450–$1,200 for most ¾″–2″ commercial services; larger RPZ units can exceed $3,000. • Annual testing: $85–$150 per device, plus parts if repairs are needed. Church Hill levies escalating fines—typically $100–$500 per day—for failure to install, maintain or test a required assembly. In severe cases, the water utility may suspend service until compliance is verified, so staying current is far less expensive than paying penalties or losing water.
