Serving Corona Since 2007
Got a test-due letter from the City of Corona Department of Water and Power? That's our specialty. Atlas Backflow handles annual backflow testing for HOAs, distribution centers, and commercial plazas across Corona — from South Corona and Dos Lagos to the industrial parks along the 91 corridor — and we file the results with your water purveyor so you don't have to chase paperwork.
If the test turns up a failure, our certified testers are also repair techs: trucks are stocked with parts for every major brand, so most western Riverside County repairs and re-certifications happen in a single visit. We also design and install custom anti-theft cages for exposed assemblies.

Corona Backflow FAQs
What does a backflow test cost in Corona, CA?
Testing starts at $90 per device in Corona, which covers the test itself, the compliance paperwork, and filing with City of Corona Department of Water and Power. DCVA, PVB, RP/RPZ, SVB, and fire-line assemblies are all included at that rate.
Why did I get a backflow test notice from City of Corona Department of Water and Power?
Water purveyors like City of Corona Department of Water and Power are required by California cross-connection control regulations to have every backflow prevention assembly tested annually by a certified tester. Atlas Backflow performs the test and files the results for you.
Can a failed backflow device in Corona be fixed the same day?
Usually, yes. Our trucks are stocked with rebuild kits and parts for every major make, so most repairs are completed on the first visit — with the re-certification test included.

Yes — same-day testing is available in Corona for an additional charge, and standard appointments are usually available within a few days. Call (562) 343-1436.
