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

What backflow testing looks like in Sunnyvale
A Sunnyvale test covers more devices than a typical suburban visit — irrigation, a pond or well line, a pool auto-fill, sometimes a barn service. We test each one, explain which connection it protects, and file each passing report with Town of Sunnyvale Public Works the same day.
Sunnyvale water authority: Town of Sunnyvale Public Works
Sunnyvale has protected large-lot zoning for decades, which makes it unusual for eastern Dallas County: half-acre and larger properties, heavy landscaping, ponds, and a rural feel a few minutes from I-30. That means big multi-zone irrigation systems, frequent pond and well draws that raise the hazard class, and a light commercial footprint along Highway 80 and Collins Road. The town distributes water and keeps its own cross-connection records.
We submit your passing backflow testing report directly to Town of Sunnyvale Public Works — no paperwork on your end. Town of Sunnyvale Public Works keeps the cross-connection records, and ponds or wells used for irrigation are treated as auxiliary supplies requiring a reduced pressure principle assembly on the town service.
