FAQs
What is backflow and why is it a concern for Dandridge businesses?
Backflow is the unwanted reversal of water flow in a plumbing system, which can pull contaminated water, chemicals, or bacteria back into the potable supply. In commercial settings—restaurants, manufacturing plants, medical facilities, etc.—the risk rises because equipment such as boilers, chemical dispensers, and irrigation systems can create pressure differences that trigger back-siphonage or back-pressure. If a backflow prevention assembly is not installed and regularly tested, contaminants can enter the public water system, posing health risks and exposing your business to fines and liability under Dandridge and Tennessee regulations.
Is backflow testing legally required for commercial properties in Dandridge, and how often must it be done?
Yes. The Tennessee Division of Water Resources and the Town of Dandridge Water Department require every commercial property with a backflow prevention assembly to have the device tested by a state-certified tester at least once per year. High-hazard accounts (e.g., medical labs, car washes) may be mandated to test twice yearly. After each test, a signed report must be filed with the water authority within 10 days. Failing to meet these deadlines can result in penalties or water-service suspension.
What does a professional backflow test involve?
1. We notify your staff and briefly shut off water to the device. 2. A state-approved differential pressure gauge is attached to all test ports. 3. We verify that check valves close properly, relief valves open at the correct pressure, and the overall assembly meets Tennessee performance standards. 4. If minor repairs or cleaning are needed (e.g., debris in check valve), we perform them on the spot, then retest. 5. Results are documented on the official Dandridge Backflow Test form, which we submit electronically to the Water Department and email to you for your records.
How long does the test take and will it interrupt my business operations?
Most tests take 20–30 minutes per device. Water is normally shut off only for 5–10 minutes, so the impact on kitchens, restrooms, or production lines is minimal. We offer early-morning, late-evening, and weekend appointments to help you avoid peak business hours, and we can stagger tests on multi-device sites to keep at least one line running at all times.
How much does commercial backflow testing cost and what factors affect the price?
In Dandridge, a standard ¾″–2″ assembly test typically ranges from $85 to $150 per device. Larger devices (2½″–4″), limited access (roof or pit installations), and required repairs or replacement parts can raise the total. We provide volume discounts for multiple devices or multiple properties, and all quotes are free and itemized so you know exactly what you’re paying for.
