Backflow Q & A

A backflow device (also called a backflow preventer) is a plumbing device designed to prevent water from flowing backward into the clean water supply. Backflow can occur when there’s a sudden change in water pressure, which could cause contaminated water (from irrigation, pools, industrial processes, etc.) to flow back into the public water system, potentially contaminating it. 

 California law requires backflow devices to be tested every year by a certified professional.

 A certified technician checks your backflow device to make sure it’s working properly and preventing contaminated water from flowing into the clean water supply.

 Testing usually costs between $75 and $150, depending on your system. If repairs or replacements are needed, we’ll provide a clear estimate upfront.

 If it fails, we’ll repair or replace the device to ensure it meets California’s safety standards.

 Failure to test your backflow device could result in fines or even suspension of your water service.
