Is backflow testing really every year?
In California, backflow prevention assemblies must be tested at least once a year. They also need a test right after installation, after any repair, and after being moved. Your water district sets the exact due date and usually mails a notice before it.
What if I miss my test deadline?
You'll usually get a second letter, then a final notice. After that some districts add fees, and some can turn off service. If your date is coming up, reach out and let us know.
Do I lose water during a backflow test?
For a few minutes. We close the valves on the device to take readings, so water past it is off briefly, then it goes right back on.
What happens if my device fails the test?
You'll hear exactly what failed and what the fix costs before we touch anything. Usually it's a cleaning or a rubber kit. Once it's fixed we test again and file the passing report. More on repairs.
Can anyone test a backflow device?
A certified backflow tester. Most districts also keep their own approved list and want results sent on their form or through their online portal.
Does someone need to meet the tester?
Usually not. If the assembly is accessible, we can test without you on site. We just need gate codes, keys to any locking cage, and a contact number in case we find a problem.
Will you file the report for me?
Yes. We submit the test report to your water district in the format it requires and send you a copy for your records.
How much does backflow testing cost?
It's $105 per device under 4 inches and $175 for 4 inches and up. Filing with your district is included. If a repair is needed, you get that price before we start.
Should I repair or replace a failed backflow preventer?
Repair, most of the time. A rebuild kit fixes the majority of failures. We'd only suggest a new one if the body is cracked, parts aren't available, it was stolen, or your property now needs a different type. More on replacement.
Do houses have backflow devices too?
Plenty of homes do, usually because of a sprinkler system, a fire sprinkler line, a pool fill or a well. If you got a notice, your district already has a device on file for your address.
