What a domestic backflow assembly does in Keller
The domestic assembly protects Keller'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. City of Keller Public Works – Utility Division 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 Keller 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 Keller 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 City of Keller Public Works – Utility Division without follow-up phone calls.

Keller water authority: City of Keller Public Works – Utility Division
Keller buys treated water wholesale and distributes it through its own system, so the city keeps its own cross-connection records and issues its own annual notices. With large lots in Hidden Lakes and Marshall Ridge and older properties around Old Town Keller, irrigation assemblies here range from brand-new to 30 years old. We test, repair if needed, and file with Keller the same day.
We submit your passing domestic backflow testing report directly to City of Keller Public Works – Utility Division — no paperwork on your end. City of Keller Public Works – Utility Division runs its own cross-connection program, so a passing report must be filed with Keller rather than a wholesale water provider.
