Backflow testing in Sunnyvale: what to expect
Sunnyvale has protected large-lot zoning for decades, which makes it an unusual town for eastern Dallas County — half-acre and larger properties, heavy landscaping, ponds, and a genuinely rural feel minutes from I-30. The practical effect on our work is scale: irrigation systems here are big, often ten to fifteen zones, and a meaningful share of properties draw at least part of their landscape water from a pond or well.
That auxiliary supply is the compliance point. A pond used for irrigation makes the town service high hazard, requiring a reduced pressure principle assembly rather than the double check that suits a city-fed system. Owners are often surprised because the pond predates the sprinklers by decades. We assess it honestly, put the reasoning in writing, and quote the right device.
Commercial and institutional work is light and concentrated — the Town East Boulevard and Highway 80 frontage, churches, and Sunnyvale ISD campuses. Because the town distributes its own water and keeps its own cross-connection records, every passing report goes to Town of Sunnyvale Public Works, filed the same day we test.
