What a domestic backflow assembly does in Murphy
The domestic assembly protects Murphy'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 Murphy 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 Murphy 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 Murphy 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 Murphy Public Works without follow-up phone calls.
What domestic backflow testing looks like in Murphy
Murphy's domestic assemblies protect restaurant carbonation and dish equipment, dental chairs and sterilizers, veterinary wash and medication connections, and school kitchens. All are high hazard, and the relief valve on a reduced pressure assembly is the part most likely to fail after years of sitting — we verify it opens on every test.
Murphy water authority: City of Murphy Public Works
Murphy built out almost entirely between the late 1990s and the 2010s, which gives it one of the most uniform backflow inventories in Collin County: thousands of residential irrigation assemblies of roughly the same age, all coming due for their first serious rebuilds at once. Commercial work is concentrated in the Murphy Marketplace and along FM 544 and Murphy Road — restaurants, medical and dental offices, and retail — plus Plano ISD and Wylie ISD campuses inside the city.
We submit your passing domestic backflow testing report directly to City of Murphy Public Works — no paperwork on your end. City of Murphy Public Works keeps the cross-connection records, and because so much of Murphy's inventory was installed in the same few years, the city issues notices in heavy seasonal waves — booking early in the cycle avoids the rush.
