Backflow Preventer Installation & Testing
Backflow preventer installation, testing, and certification for Los Angeles residential and commercial properties.
A backflow preventer stops contaminated water from flowing backward into the clean water supply u2014 a requirement for irrigation systems, commercial properties, and any connection that could allow non-potable water to enter the supply line. Los Angeles requires annual testing and certification on most commercial backflow devices.
We install backflow preventers for irrigation systems, commercial connections, and fire suppression systems, and perform the annual testing and certification required by LADWP and the City of LA. We’re certified backflow testers and can handle both the installation and the annual compliance testing so you don’t have to track down a separate vendor.
