Backflow testing requirements in Denton
Denton Water Utilities requires every backflow prevention assembly in Denton 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 Denton's drinking water supply.
What a Denton 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 Denton Water Utilities. If it fails, we tell you exactly which component failed and quote the repair before doing any work.
