That letter means your water district has a backflow device listed at your address, and it wants a passing test report by the date shown. You need a certified tester to test it and file the results. Nothing more complicated than that.
What the notice is
Every water supplier in California has to guard the public system against contamination from private plumbing. The State Water Board's Cross-Connection Control Policy Handbook requires them to track each backflow assembly and have it tested every year. Your notice is that yearly reminder.
What to do, step by step
- Check the date and device info on the letter. Look for the size, type and serial number.
- Call a tester your district approves. Send them a photo of the notice.
- Make sure they can reach the device. Unlock gates and cages, or share the codes.
- If it doesn't pass, OK the repair. The district only accepts a passing report. More on repairs here.
- Ask for your copy once the report is filed.
What if I miss the deadline?
Districts usually send a second or final notice. After that, depending on the district, you may face fees or interruption of water service. If you're close to the date, call and mention it when booking.
What if I don't think I have a backflow preventer?
Look near the water meter, along the front of the building, beside irrigation valves, or at the fire sprinkler riser. If you can't find it, a tester can locate it. If it was removed, the district must be notified.
Does the notice mean something is wrong?
Not at all. Everyone with a device gets one every year. It doesn't mean anything failed or that your water has a problem.
Related questions
How often do I need a backflow test?
Once a year at minimum. A device also needs testing right after it's installed, repaired or moved. Your water district picks the due date and normally mails a reminder ahead of time.
What happens if I don't test by the due date?
Water districts typically send a reminder, then a final notice. Continued non-compliance can lead to fees and, in some districts, interruption of water service. If your deadline is close, contact us and mention the date.
Who sends the report to the district?
We do. The report goes to your district the way they want it, and you get your own copy.
