Backflow Testing, Repair & Installation in Carson, CA
Certified backflow services for Carson homes, businesses, and industrial properties — annual testing from $90 per device, with your California Water Service (Cal Water) paperwork filed for you.
Serving Carson Since 2007
If California Water Service (Cal Water) has mailed you an annual backflow test notice — or LA County's cross-connection program has flagged your property — Atlas Backflow can test, certify, and file your paperwork within days.
Carson is heavy-industry country, and that's our specialty: 60 devices under management across the refinery-adjacent corridors, logistics warehouses off the 405 and Alameda, truck yards, and commercial centers near the SouthBay Pavilion. Big fire lines, large-diameter RPs — our trucks carry parts for all of it.
And if your device fails? Our trucks carry a full parts inventory, so most Carson repairs happen on the same visit — with re-certification included when we do the repair. We also build and install custom anti-theft cages, an increasingly common need for exposed commercial assemblies around Carson.
Carson Testing: Starting at $90 Per Device
All device types — DCVA, PVB, RP/RPZ, SVB, fire lines. Price includes the test, compliance documentation, and submittal. Same-day service available at an additional charge.
