Backflow Prevention — Testing, Repair, and Certification.
Backflow can introduce contaminants, chemicals, or bacteria into your clean water supply. In California, backflow prevention devices are required on most commercial and many residential properties — and most East Bay water districts require annual testing.
Overview
Our certified technicians handle the full backflow process — testing, repair, replacement, and filing certification reports with your water district. If your device fails inspection, we can often complete the repair the same day so you pass quickly. We'll also tell you if your property requires a device in the first place.
