Backflow Testing in Tennessee: Costs, Requirements & How to Find the Best Certified Testers
Tennessee is one of few states where the water utility handles testing itself for many customers. Nashville MWS inspects and tests assemblies annually, charging $50 per device on the water bill. Tennessee American Water moved to the BackflowBMP portal in 2024. Fleming Training Center issues Tennessee's tester certificates of competency.
Why Backflow Testing Matters in Tennessee
Tennessee’s TDEC Fleming Training Center issues certificates of competency to backflow assembly testers. Nashville Metro Water Services uniquely inspects all devices annually — charging $50 per device on the customer’s water bill, similar to LVVWD in Nevada. City of Franklin similarly uses city inspectors who bill testing fees on the water bill. Tennessee American Water uses BackflowBMP portal (since 2024) and requires RPZ assemblies on all irrigation systems, with non-RPZ devices required to be replaced by 2027. Memphis, Chattanooga, and Knoxville have their own tester programs.

How Much Does Backflow Testing Cost in Tennessee?

How Long Does Backflow Testing Take in Tennessee?
MWS-inspected Nashville assemblies: MWS schedules and performs inspection, no scheduling needed. For TAWC and other TN utilities: standard 25–40 minutes per assembly. TAWC irrigation note: non-RPZ assemblies that fail inspection must be replaced immediately (no repair option) and all non-RPZ must be replaced by 2027.
What to Expect on Test Day
Your tester arrives, locates your backflow assembly (typically near the water meter or service entrance), and connects calibrated differential pressure gauges to the test cocks. Water shuts off for 15–30 minutes during testing. You receive a signed test report immediately. Pass: results are filed with your utility. Fail: the tester identifies the fault and repairs or returns within the required compliance window. Always confirm your tester files results with your utility — request confirmation before they leave.
