What a domestic backflow assembly does in Dallas
The domestic assembly protects Dallas'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. Dallas Water Utilities 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 Dallas 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 Dallas 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 Dallas Water Utilities without follow-up phone calls.

Dallas Water Utilities requires annual backflow assembly testing for every property with an irrigation system, fire line, or commercial water connection. Failure to test on time can lead to fines or service interruption. Our crews cover every Dallas ZIP code and file your test directly with DWU the same day.
