If you received a letter from your water district about backflow testing, you are not alone. Every year, thousands of South Bay property owners get these notices. The letter is not a fine or a penalty. It is simply a reminder that your backflow prevention device is due for its annual test. But there is a deadline, and ignoring it can lead to real consequences.
What the Notice Means
Your local water district keeps a registry of all properties with backflow prevention devices. This includes homes with irrigation systems, commercial buildings, multi-family housing, and any property where the risk of water contamination exists. The district is required by state law to ensure these devices are tested annually. The notice is their way of telling you it is time.
How Long Do You Have to Respond
Most South Bay water districts give you 30 to 60 days from the date of the notice to schedule a test and submit the results. The exact deadline is printed on your letter. If you are close to the deadline, call a tester immediately. Many companies offer same-week or next-day scheduling in the South Bay, especially in San Jose and Santa Clara.
What Happens If You Ignore It
- First reminder: A second notice is mailed if you miss the deadline.
- Late fees: Some districts charge a late fee or administrative penalty of $50 to $150.
- Water service restriction: In extreme cases, the district can restrict your water service until the test is completed and filed. This is rare for residential properties but more common for commercial accounts.
- Compliance flag: Your property may be flagged for non-compliance, which can complicate property sales or refinancing.

What You Need to Do
First, locate your backflow prevention device. It is usually near your main water shutoff, in a utility room, or outside near the street. If you cannot find it, a tester can locate it during the visit. Next, hire a certified backflow tester. They must hold a current California backflow tester certification. The tester will perform the test, fill out the official form, and submit it directly to your water district. You should receive a copy for your records.
What If Your Device Fails
If the test fails, the device must be repaired or replaced. The water district will be notified of the failure, and you will have a new deadline to complete the repair and pass a retest. Many testing companies also offer repair services, which simplifies the process. Do not delay the repair. The district tracks failure-to-repair timelines, and extensions are not always granted.
Bottom Line
The notice is routine, not punitive. It is simply a reminder to stay compliant with California water safety regulations. Schedule a test with a certified company, confirm they file the paperwork directly with your district, and keep your copy of the report. If you act promptly, the entire process takes less than an hour and costs under $150 in most cases.
