Frequently asked questions
Why do I have to get my device tested and how often does it need to be tested?
Like any other mechanical device, over time a backflow assembly may fail. To ensure it is working properly to protect public drinking water systems, California State Law requires all backflow prevention assemblies whether they are installed internally or at a water service meter to be tested annually, upon new installation, or after repairs or replacement is completed . ​
What to expect from a Big Gauge Backflow test of your assembly
During a backflow assembly test, the tester will conduct a thorough assessment of the device. This involves a visual inspection to check for any visible signs of leaks, damage or wear. The functionality of the assembly will then be tested with a pressure gauge to ensure it's effectively stopping the reverse flow of water and meeting compliance requirements (the flow of water will be stopped for ~3-5 minutes during this step). One completed, water flow is restored, the tester will affix a tag if required, fill out paperwork, submit results to the water authority and provide you a copy of results.
​
Our Backflow Assembly Testers are California-Nevada Section American Water Works Association (CA-NV AWWA) certified and have experience testing all makes and models of backflow prevention assemblies approved for use in the State of California.
How do I schedule testing, and do I have to submit the report to my city or water department?
The best way to get on schedule is to use our Request form on our website where you can enter your contact info and upload an image of you water department notice, blank test form, post card or any other notification you received.
We will contact you to confirm your information, schedule the test, ask if you would like to be present or not, and discuss permissions in case we need to service/clean the assembly.
Once testing is completed, we will submit all of the required forms/reports to your city or water department and also provide you a copy. There’s nothing else for you to do. We’ll take it from there.
What happens if my backflow assembly fails the test?
If we tested your assembly and failed it, we will immediately notify you and provide an estimate and plan for repair of the assembly. With your approval, we will get you on schedule, pick-up the parts, complete the repairs, test it and submit the "passed" results to your city or water department. We will always try to repair your device before we recommend a replacement.
How long do backflow preventers last and how often do they have to be repaired?
Depending on multiple factors i.e. water quality, usage, pressure, a backflow assembly may last anywhere from 10-20 years some even 30+ in optimal conditions. Backflow assemblies contain multiple moving parts including springs, valves, and rubber seals. Valves open on downstream demand and close once demand ceases. Backflow assemblies may need new internal parts every 3-5 years, some can go as long as 7-10 years before needing repair.
