What is backflow?
Backflow is the change of flow of water back to the source where it came. This can present to be a major public safety concern when the water is contaminated if it returns to the source of water.
What is a Backflow Prevention Assembly?
A Backflow Prevention Assembly is a mechanical assembly that prevents contaminated water from flowing out of common systems (such as but not limited to Landscape Irrigation, Fire Suppression and Boiler Systems) back into the drinking water supply.
Why do Backflow Prevention Assemblies need to be tested?
All Backflow Prevention Assemblies have calibrated internal elements that break over time. Common elements such as the springs, seals, and various moving parts within your backflow prevention assembly will gradually wear out or fatigue. Periodic testing is the only way to make sure your backflow prevention device is in proper functioning order.

Another common problem is leaking joints, where water seeps out through the cracks between two pipes
Corrosion, roots, and general blockages are other common issues that affect sewer drains. In these cases, you may notice a sluggish drain, an odor problem, a mold issue, unexpectedly lush patches in your grass, or foundation issues with your home.
Why do I need a backflow test?
- Backflow prevention programs are in place to protect your drinking water from contamination.
- To ensure that your backflow prevention assembly is in proper working condition.
- A backflow prevention assembly is a mechanical assembly that will at some time fail.
- It's the law.

Frequently Asked Questions
What is backflow testing?
Backflow testing checks a backflow prevention assembly to confirm it still stops contaminated water from reversing into the clean drinking water supply. A certified tester uses calibrated gauges to verify the internal parts work.
Is backflow testing required by law?
In most cases, yes. California cross connection rules require assemblies on many connections, and water providers require annual testing. Missing a test can bring enforcement action.
How often is backflow testing required?
Most water providers require annual testing. Some high risk connections may need it more often. Your provider or a certified tester can confirm your schedule.
Who needs a backflow test?
Commercial properties and any site with irrigation, fire suppression, or boiler systems typically need one. Some homes with irrigation or wells do as well.
What happens if my backflow assembly fails the test?
A failed assembly means worn or broken internal parts. It must be repaired or rebuilt and retested promptly to stay compliant and protect the water supply.
How long does a backflow test take?
A standard test usually takes under an hour. If a repair is needed, that adds time. We test, report the results, and handle any repair.
Why does a backflow preventer fail?
The springs, seals, and check valves inside wear out and fatigue over time. That gradual wear is exactly why periodic testing is required.
Who can perform a backflow test?
A certified backflow tester must perform and document the test. We handle the testing, any needed repair, and the reporting to your water provider.
