What Our Customers Say
Trusted by homeowners, HOA managers, and commercial property owners across the Inland Empire.
Southern California Backflow made the whole process effortless. They scheduled us, showed up on time, tested our backflow device, and filed the report with our water district — all in one visit. We had been getting notices from the city for years. Not anymore.
Our irrigation backflow failed its test and I was worried about a big repair bill. The technician diagnosed the problem quickly, had the parts on his truck, and fixed it the same morning. He retested right after and filed the passing report before he left. Very professional.
I manage multiple commercial properties and keeping track of backflow testing due dates was a nightmare. Southern California Backflow handles it all — they contact me when testing is due, handle the scheduling, and file all the reports. My properties are fully compliant and I don't have to think about it.
