New construction backflow testing in Sunnyvale
Nearly every new home, commercial building, and development in Sunnyvale needs its original backflow assembly tested before city approval can move forward. We show up to the job site, verify the builder-installed device is the right type for the hazard and installed according to city code, test it with calibrated gauges, and report the result to Town of Sunnyvale Public Works with the proper permitting information.
Clean-outs, quick repairs, and installs
New devices often fail their first test because debris from new lines gets caught in a check or relief valve. When that happens in Sunnyvale, we can often clean out the assembly, make a quick repair, re-test, and keep the project moving. If an assembly is missing or the installed one is wrong for the hazard, we can install the correct backflow assembly for irrigation, domestic, or fireline service.
City reporting and project updates
Each city has its own approval process for new construction backflow work. We keep builders, contractors, and property owners updated, send the official test reports as soon as possible, and file passing results directly with Town of Sunnyvale Public Works. Our work covers residential and commercial projects, including irrigation, domestic, and fireline assemblies.
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 new construction backflow test, repair & install 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.
