When replacement is the right call in Sunnyvale
We recommend replacing an assembly in Sunnyvale when the body or bonnet is cracked from a freeze, the model is obsolete and rebuild kits are no longer produced, corrosion has pitted the seats, the assembly is the wrong size or type for the hazard, or repeated repairs are no longer economical. Newer assemblies are also easier and cheaper to test and rebuild going forward.
Code-compliant installation
We install USC-approved assemblies sized for your service and hazard level, set at the height and orientation Town of Sunnyvale Public Works requires, with proper clearances for future testing. For irrigation we install double check and pressure vacuum breaker assemblies; for domestic and high-hazard applications, reduced pressure principle assemblies; for fire lines, DCDA and RPDA units. Freeze protection and insulated enclosures are available for exposed Sunnyvale installations.
Tested and filed before we leave
Every new assembly is tested immediately after installation, and we submit that initial report to Town of Sunnyvale Public Works on your behalf. You get a copy for your records plus the due date for next year's test, and we can put your property on our annual reminder list.
What backflow replacements looks like in Sunnyvale
The typical Sunnyvale replacement follows a hazard-class change — a pond or well now feeds the sprinklers — or a body cracked by freeze. We install the correct assembly at testable height with proper relief drainage and file the certification with the town immediately.
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 replacements 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.
