Cross connection and Backflow Protection Program
Backflow Testing
The State of California requires backflow prevention assemblies be installed on all hazardous cross-connections to help keep the water supply safe.
Every backflow prevention device must be tested once a year in accordance with California State Law. You as a homeowner are responsible for hiring a licensed backflow tester to perform the annual test and certification of the backflow assembly(s) on your property.
Testing reminder letters are sent out September 18th of the testing year and tests are due no later than November 3rd.
The second notice (past due) will be sent 11/4 if we do not have a passing test in the system
If your backflow device does not pass the annual test, talk with your tester for recommendations on repair or replacement. A passing test is required within 30 days of your test due date

What are cross-connections?
A cross-connection is an interconnection or possible interconnection (permanently or temporarily) between a potable water supply (water safe for drinking) and a non-potable supply (not safe for human consumption).
Cross-connections can occur between a potable water supply and private irrigation systems, fire sprinkler systems, well systems, and any other pipe systems that receive the potable water supply.
What is Backflow?
Backflow is an unintended or unwanted reversal of water flow or other substances through a cross connection into a water system's distribution. Backflow can result in a potentially serious public health hazard.
Backflow occurs when a loss in water pressure (commonly due to a fire hydrant being opened, a water main break or simply abnormally high water usage)
Can I test my Backflow Device Myself?
The short answer is no, a customer may not test their own backflow device.
Backflow testers are certified by a national agency every 3 years. Backflow testers must use specialized testing equipment that must be calibrated every year.
Backflow specialists are trained professionals who are taught specifications and laws that must be followed when installing, repairing, replacing, or testing a backflow device.
