What a domestic backflow assembly does in Colleyville
The domestic assembly protects Colleyville'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 Colleyville 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 Colleyville 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 Colleyville 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 Colleyville Public Works without follow-up phone calls.
What domestic backflow testing looks like in Colleyville
Domestic assemblies in Colleyville protect restaurants, medical and dental offices, church kitchens, and school buildings. The high-hazard classification usually comes from food service or clinical equipment. On acreage properties with a well, the domestic service itself also needs reduced pressure protection, which is the single most common compliance gap we correct here.
Colleyville water authority: City of Colleyville Public Works
Colleyville is an acreage community, and that changes backflow work substantially. One-acre and larger lots along Glade Road and Whittier Heights run large multi-zone irrigation systems, private wells next to city water, pool and pond fill lines, and occasionally livestock water — all cross-connections the City of Colleyville expects to see protected and tested every year.
We submit your passing domestic backflow testing report directly to City of Colleyville Public Works — no paperwork on your end. City of Colleyville Public Works requires reduced pressure protection wherever a well, pond, or other auxiliary supply exists alongside the city connection, tested annually.
