What Is a Backflow Preventer and Why Is It Important?

Backflow preventers are critical for safeguarding the potable water supply from contamination caused by backflow—when used or potentially contaminated water flows back into clean water lines. This can pose serious health risks to your home and the public water system.

A backflow prevention device works by blocking reverse water flow, ensuring your plumbing system remains sealed and the water supply is protected. Most businesses and multi-family residential buildings in California are legally required to have these devices, and some single-family homes may need them based on their plumbing systems.

Expert Backflow Prevention Inspections and Testing

At Courtesy Plumbing, we offer comprehensive backflow prevention services, including annual inspections as required by California law. During our inspections, we test your device to ensure it’s functioning within the proper parameters and ready to perform reliably for another year. 

Additionally, we provide other relevant services, such as copper pipe installation and appliance installation. Should your backflow preventer need maintenance, repairs, or even replacement, our skilled team has the tools and expertise to get the job done right.
