Fire line backflow testing rules in Sunnyvale
Any building in Sunnyvale with a fire sprinkler system has a dedicated fire line backflow assembly — usually a double check detector assembly (DCDA) or a reduced pressure detector assembly (RPDA). Town of Sunnyvale Public Works requires these to be tested annually by a licensed tester, and the fire marshal may ask for the current report during an inspection. Because fire lines are large diameter and often installed in a pit or vault, testing takes coordination — that is what our crews do every week.
Minimal downtime for Sunnyvale buildings
We schedule fire line tests in Sunnyvale around your operating hours, including early mornings, so tenants and customers are not disrupted. Our technicians notify your monitoring company before the water is isolated so no false alarm is dispatched, complete the test, then verify the system is back in service before leaving. We handle confined-space vaults, flush-mounted pits, and riser room installations.
Repairs, rebuilds, and replacements
If a fire line assembly in Sunnyvale fails, we quote the repair on the spot. We rebuild checks and relief valves, replace worn rubber and seats, and can replace the full assembly when repair is not cost effective. After any repair we re-test and file the passing report with Town of Sunnyvale Public Works and provide a copy for your fire inspection file.
What fireline backflow testing looks like in Sunnyvale

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 fireline 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.
