Backflow testing requirements in Corinth
City of Corinth Water Department requires every backflow prevention assembly in Corinth to be tested at least once each year by a licensed backflow assembly tester. That includes irrigation double-check and pressure-vacuum breaker assemblies, domestic reduced-pressure assemblies feeding buildings, and fire line detector checks. The test verifies that the assembly still closes under reverse pressure so contaminated water can never siphon back into Corinth's drinking water supply.
What a Corinth backflow test looks like
A licensed technician arrives with calibrated test gauges, isolates the assembly, records the differential pressure across each check valve and the relief valve, then restores service. On-site time is normally 20 to 30 minutes and you do not need to be home — we only need access to the assembly, so an unlocked gate or a gate code is enough. If the assembly passes, we complete the state test-and-maintenance report and submit it directly to City of Corinth Water Department. If it fails, we tell you exactly which component failed and quote the repair before doing any work.

What backflow testing looks like in Corinth
A Corinth test starts at the meter so we can confirm which devices belong to the address, then we gauge each one and file the result with the City of Corinth the same day. Because the city's supply blends groundwater and treated water, we also flush and inspect the check seats while we are in the assembly — the small step that keeps a marginal Corinth device passing next year.
Corinth water authority: City of Corinth Water Department
Corinth sits between I-35E and the south shore of Lewisville Lake, and it distributes its own water through a mix of local wells and treated supply from the Upper Trinity Regional Water District. That matters for compliance: your cross-connection record lives with the City of Corinth, not with a regional wholesaler. Most of the work here is residential irrigation in neighborhoods like Lake Sharon and Meadowview, plus school district and retail assemblies along Corinth Parkway and FM 2181.
We submit your passing backflow testing report directly to City of Corinth Water Department — no paperwork on your end. Corinth distributes its own water and keeps its own cross-connection records, so reports go to the City of Corinth Water Department rather than to a regional wholesaler.
