FAQs
What is a backflow preventer and why does my Harriman business need one?
A backflow preventer is a mechanical device installed in your plumbing system that stops contaminated water from flowing backward into the municipal supply. In commercial settings—restaurants, manufacturing plants, health-care facilities, multi-tenant buildings—chemicals, bacteria, or other pollutants can siphon back into the public lines during pressure changes (fire-hydrant use, main breaks, etc.). Harriman’s local water authority and state plumbing codes require approved backflow prevention to protect public health, avoid costly fines, and keep your business in regulatory compliance.
Is a backflow preventer required by code in Harriman?
Yes. Both the Tennessee State Plumbing Code (if you are in Harriman, TN) and local amendments mandate backflow prevention on any cross-connection that could endanger drinking water. The Harriman Utility Board and the regional health department enforce annual testing and proper installation by a licensed commercial plumber. Non-compliance can lead to water service shut-offs, penalties, and liability if contamination occurs.
How often does my commercial backflow preventer need to be tested or certified?
Harriman follows the standard annual certification rule: every testable backflow preventer (RPZ, DCVA, PVB, etc.) must be inspected once per year by a state-licensed tester. Certain high-hazard sites—hospitals, car washes, chemical processors—may be required to test twice a year. After each test, a signed report is submitted to the city’s cross-connection control office. Failing to file these reports on time can result in written notices or immediate water shut-off.
Which type of backflow preventer is best for my commercial property?
The right device depends on your hazard level, water usage, and plumbing layout: • Reduced-Pressure Zone Assembly (RPZ) – Required for high-hazard applications such as medical gases, chemical mixing, or irrigation with fertilizers. • Double Check Valve Assembly (DCVA) – Common for standard commercial potable water systems, fire-sprinkler feeds without chemical additives, or apartment complexes. • Pressure Vacuum Breaker (PVB) – Often used on dedicated lawn-sprinkler lines where there is no indoor cross-connection. Our licensed technicians evaluate your site, discuss code requirements, and recommend the safest, most cost-effective option.
What should I expect during installation, testing, or repair service?
1. Site evaluation: We locate the water shut-off, drainage points, and existing cross-connections. 2. Water shutdown: A brief interruption (typically 30–60 minutes) while we install or remove the device. 3. Device installation or repair: We mount the assembly, ensure proper clearance, and use lead-free fittings as required by federal law. 4. Performance testing: Using calibrated gauges, we verify valve function, record differential pressure, and make any necessary adjustments. 5. Documentation: You receive a detailed test report and we forward copies to the Harriman Utility Board to keep you compliant. 6. Restoration & cleanup: Water service is restored, and we leave the workspace clean and code-labeled for easy inspection.
