Received a Backflow Testing Notice?
Do not panic — but do not wait either. We help property owners across the South Bay resolve their water district testing notices quickly and stress-free. Most appointments are completed within the same week, and we handle all the paperwork so you do not have to deal with the water district directly.
Why You Received The Notice
First — take a breath. Receiving a backflow testing notice does not mean something is wrong with your water. It is a routine compliance requirement that water districts send to all property owners with backflow prevention devices. By law, these devices must be tested annually by a certified tester to ensure they are still functioning properly and protecting the public water supply.
Your water provider maintains a database of every backflow device in their service area. When a device's annual certification expires, the system automatically generates and mails a testing notice to the property owner. It is purely administrative — but it does have a real deadline you need to meet.
The notice typically includes your device's location, its last test date, the deadline for completing the test, and instructions for submitting the certification report. If any of this information looks incorrect, we can help you sort it out with the water district.

What Happens If You Ignore It
Ignoring a backflow testing notice is not like ignoring a junk mail flyer. Water districts have real enforcement powers, and the consequences escalate quickly.
Financial Penalties
Water districts can and do issue fines for non-compliance. The amount varies by provider and jurisdiction, and penalties can escalate for repeated or long-running violations. Your notice states the specific requirements and consequences for your property.
Water Service Shutoff
If you ignore repeated notices, your water provider has the legal authority to shut off water service to your property until the backflow test is completed and certification is filed. No property is exempt — residential, commercial, and industrial all face the same enforcement.
Property Liens
In some jurisdictions, unresolved backflow compliance violations can result in a lien being placed on your property. This can block a home sale, complicate refinancing, and create title issues that are expensive to resolve.
Legal Liability
If a contamination event occurs and your property's backflow device is found to be non-compliant, you could face significant legal liability. Insurance policies may not cover damages resulting from known code violations.
Bottom line: The fastest and cheapest way to resolve a notice is to schedule your test as soon as you receive it. Ignoring it only makes things worse and more expensive.
How Long Do You Have?
Your deadline is set by your water provider and will be stated on the notice you received. Read it carefully — it lists the specific due date and how to submit your results. Don't wait until the last minute, because if your device needs a repair you'll want buffer time to re-test.
Read Your Notice
Your water provider's notice states your specific deadline and where to file results. This is the only authoritative source for your due date.
Annual Requirement
California State Law (Title 17) requires backflow prevention assemblies to be tested at least once a year by a certified tester.
File Results Promptly
Test reports must be submitted to your water provider. Some districts require submission within a short window after the test — your notice will specify.
What if your device fails the test?
If your device fails its certification test, it must be repaired or replaced and re-tested. Most water providers require a passing result to be on file, so schedule early to leave room for any needed repairs. We handle both testing and repair, so you're covered either way.
What Is Backflow Testing?
Backflow testing is a technical inspection that verifies your backflow prevention device is working correctly. A certified tester connects a calibrated gauge kit to the device and measures water pressure at specific test points to confirm that each check valve is sealing properly and preventing contaminated water from flowing back into the public water supply.
The test itself takes about 15 to 30 minutes for a standard residential device. The tester records all pressure readings, gauge serial numbers, and pass/fail results on an official certification form. If the device passes, you receive a completed certification report that must be filed with your water district.
