Backflow Prevention & Testing
Backflow Prevention & Testing in Los Angeles
Certified backflow testing and device installation to protect your water supply.
What Is Backflow Prevention & Testing?
Backflow prevention devices stop contaminated water from flowing back into the clean water supply. LA County requires annual testing for irrigation systems, commercial properties, and certain residential setups.
We’re certified to test, repair, and install backflow assemblies, and we file results directly with the water authority.
