What a domestic backflow assembly does in Sunnyvale
The domestic assembly protects Sunnyvale's public water supply from the water inside your building. High-hazard uses — food service, medical suites, boilers, chemical mixing, cooling towers — are typically protected by a reduced pressure principle assembly (RPZ) at the point of service. Town of Sunnyvale Public Works requires annual certification, and a missed test can lead to violation notices or a hold on your certificate of occupancy or health inspection.
Testing without shutting your business down
Testing a domestic assembly briefly interrupts water to the building, so timing matters. We schedule Sunnyvale restaurants and clinics before opening or after close, and coordinate with facility staff on apartment and office buildings so tenants get notice. Actual isolation time is usually under 15 minutes per assembly.
Multi-site and portfolio testing
If you manage several properties in Sunnyvale or across DFW, we can put every assembly on one annual schedule, send one consolidated invoice, and track due dates for you. Property managers use us because reports get filed with Town of Sunnyvale Public Works without follow-up phone calls.
What domestic backflow testing looks like in Sunnyvale
Domestic assemblies here protect school and church kitchens, small commercial food service, and the main service on properties that also have a well or pond pump. When an auxiliary supply exists, the domestic connection is high hazard and requires a reduced pressure assembly with a working relief valve.
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 domestic 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.
