CA/NV AWWA certified backflow prevention testing, repair, and reporting — serving all of San Diego County with integrity and certified excellence.
SD Coastal Backflow was founded on a simple belief: clean water is not a luxury — it's a fundamental right. As a CA/NV AWWA certified backflow prevention specialist, we bring professional-grade testing, repair, and reporting to San Diego's residential, commercial, and HOA customers.
Every assembly we test is logged, reported, and filed with the appropriate water authority. Every repair is performed to the highest standards by a certified technician who carries the credentials to back it up. We don't subcontract, we don't cut corners, and we never send someone to your property who isn't qualified.
With extensive hands-on field experience and a deep understanding of water systems, our technicians bring real-world knowledge to every job — not just a test kit.
