What a domestic backflow assembly does in Azle
The domestic assembly protects Azle'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 Azle 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 Azle 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 Azle 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 Azle Public Works without follow-up phone calls.
What domestic backflow testing looks like in Azle
Domestic assemblies in Azle protect restaurant kitchens, fuel pad equipment, auto bays, and — distinctively here — marine and RV service connections with flush stations and chemical mixing. Those are high hazard, so we verify that the reduced pressure assembly's relief valve genuinely opens rather than assuming it will.
Azle water authority: City of Azle Public Works
Azle sits on the northeast shore of Eagle Mountain Lake straddling the Tarrant and Parker county line, and the lake is the defining factor in our work here. Lake-side properties frequently pump surface water for irrigation, and that auxiliary supply puts the city connection in the high-hazard class, requiring a reduced pressure principle assembly rather than a double check. Commercial work runs along Highway 199 — marine and RV service, restaurants, auto shops, and retail.
We submit your passing domestic backflow testing report directly to City of Azle Public Works — no paperwork on your end. City of Azle Public Works keeps the records, and lake or well supplies are treated as auxiliary sources here — those properties require a reduced pressure principle assembly on the city service rather than a double check.
