Why Did the Water Department Send Me a Backflow Notice?

Receiving a backflow notice from your water department can feel alarming, especially if you've never dealt with backflow prevention before. You might be wondering what it means, why you received it, and what steps you need to take to resolve the issue.

The good news is that backflow notices are a routine part of water safety compliance, and addressing them is usually straightforward.

Our Los Angeles Backflow Testing experts at Atlas Backflow Services break down exactly why you may have received a notice and what you should do next.

What Is a Backflow Notice?

A backflow notice is an official communication from your local water purveyor—such as the Los Angeles Department of Water and Power (LADWP)—informing you that your property has a compliance obligation related to a backflow prevention assembly.

These notices are typically sent to property owners, business operators, or property managers who have a backflow device installed on their water service line.

Our Los Angeles Backflow Testing experts emphasize that these notices should never be ignored. They are legal compliance requirements, and failing to act can result in fines, water service shutoff, or even legal action.

The Most Common Reasons You Received a Backflow Notice

There are several reasons your water department might send you a backflow notice. Understanding the specific reason behind your notice will help you take the appropriate next steps.

1. Annual Testing Is Due

The most common reason for a backflow notice is that your annual testing deadline is approaching or has passed. California state law requires that all backflow prevention assemblies be tested at least once per year by a certified tester.

Our Los Angeles Backflow Testing experts note that water purveyors typically send reminder notices 30 to 60 days before the deadline, followed by additional notices if the test isn't completed on time.

2. A New Backflow Device Was Installed

If you recently installed a new backflow prevention assembly—whether for a new construction project, a renovation, or a system upgrade—you'll likely receive a notice requiring an initial test to verify the device is functioning correctly.

New installations must be tested immediately upon installation and registered with the water purveyor.

3. Your Property Has a Cross-Connection Hazard

Water departments regularly survey properties for cross-connection hazards—situations where contaminated water could potentially flow back into the public water supply. If your property has been identified as having a potential hazard (such as an irrigation system, fire suppression system, boiler, or commercial equipment connected to the water line), you'll be required to install a backflow prevention assembly.

Our Los Angeles Backflow Testing experts frequently help clients understand and respond to these initial cross-connection notices.

4. A Previous Test Failed or Was Incomplete

If your last backflow test resulted in a failed assembly or the test report was incomplete, the water department will issue a notice requiring repairs and a follow-up test. Failed devices must be repaired or replaced promptly to maintain compliance.

5. Missing or Late Test Reports

Sometimes the test was performed, but the report wasn't submitted to the water purveyor on time. Even if you've already had your device tested, the water department's records may not reflect this if the paperwork wasn't filed correctly.

Our Los Angeles Backflow Testing experts recommend always working with a reputable testing company that handles report submission directly to avoid these administrative issues.

6. Change of Ownership or Tenant

When property ownership changes or a new business tenant takes over a commercial space, water departments often issue notices to ensure that compliance responsibilities transfer properly.

The new owner or tenant may be required to provide updated contact information and verify that the backflow device has been recently tested.

What Information Is Included in a Backflow Notice?

A typical backflow notice from a water department includes:

• The property address and water account number

• The type and location of the backflow assembly

• The reason for the notice (annual testing due, failed test, etc.)

• The deadline for completing the required action

• Potential penalties for non-compliance

• Instructions for hiring a certified tester

• Contact information for the water department's cross-connection control program

Our Los Angeles Backflow Testing experts recommend reading the notice carefully and noting all deadlines immediately. Most notices give property owners 30 days or less to respond.

What Happens If You Ignore a Backflow Notice?

Ignoring a backflow notice can lead to serious consequences. Water departments take cross-connection control very seriously because backflow incidents can contaminate public drinking water supplies.

Common penalties for non-compliance include:

• Monetary fines that can range from $100 to several thousand dollars

• Water service termination, which can shut down your business or property

• Legal action in cases of repeated non-compliance

• Liability exposure if a backflow incident occurs on your property

Our Los Angeles Backflow Testing experts have helped countless clients restore service after shutoffs caused by ignored notices, but the easiest solution is always to address the notice promptly.

Steps to Take After Receiving a Backflow Notice

If you've received a backflow notice, follow these steps to resolve it quickly:

1. Read the Notice ThoroughlyIdentify the reason for the notice, the required action, and the deadline. Make note of any reference numbers or account details you'll need when scheduling service.

2. Contact a Certified Backflow Testing Company

Only AWWA-certified or USC-FCCCHR-certified professionals can legally test backflow assemblies in California. Atlas Backflow Services employs fully certified technicians who can quickly schedule your test and ensure compliance.

3. Schedule Your Test Promptly

Don't wait until the last minute. Our Los Angeles Backflow Testing experts recommend scheduling your test at least two weeks before the deadline to allow time for any necessary repairs or follow-up testing.

4. Confirm Report Submission

After your test is complete, confirm that the testing company has submitted the report to your water purveyor. Reputable companies like Atlas Backflow Services handle this automatically, but it's always wise to verify.

5. Keep Your Records

Store a copy of your test report, the original notice, and any correspondence with the water department. These records are essential for future compliance and potential property transactions.
