Seattle’s Seasonal Backflow Notices

Each year, Seattle’s Department of Public Utilities sends thousands of reminder letters urging property owners to test their backflow prevention assemblies. These notices often spike in spring and early summer. Areas like Northgate, Capitol Hill, and Rainier Valley typically see increased testing demand during this period.

If you're a licensed tester, this is your window to gain visibility and help property owners avoid fines. If you're a homeowner, knowing the timeline—and connecting with a certified tester early—keeps your water service compliant and uninterrupted.

Is Backflow Testing Required in Seattle?

Yes. Seattle requires annual testing of all backflow prevention assemblies (BPAs). This includes residential and commercial properties with irrigation systems, fire lines, boilers, and more.

These requirements come from the Washington Administrative Code (WAC) and are enforced locally by Seattle Public Utilities (SPU).

If your property has a BPA, you're required to:

• Test annually using a certified backflow tester
• Submit results to the city or third-party platform (if applicable)
• Replace or repair failed assemblies promptly

What Happens If You Don’t Test?

If you skip annual testing or fail to submit results, Seattle Public Utilities may:

• Send violation notices
• Issue fines or water shut-off warnings
• Require you to install a new assembly at your own cost
• Flag your property for compliance follow-up

Testing on time helps protect public water and avoids penalties. Most violations stem from owners who are unaware—so reminders and proactive testing are key.

Where to Start When Searching for a Certified Tester

Seattle has a wide network of certified backflow testers, but finding the right one can feel overwhelming. Start by searching by ZIP code or neighborhood—many licensed testers are local and already familiar with the water systems in areas like Green Lake, Ballard, or West Seattle.

Do All Testers Need to Be Certified in Washington?

Yes. In Washington State, testers must be certified through the Department of Health’s Cross-Connection Control Certification Program. This ensures they are trained, authorized, and up to date on state regulations. If you're ever unsure, you can ask a tester to provide proof of certification or check with the issuing authority.

Who Receives Test Reports in Seattle?

Backflow test results for properties within Seattle city limits are typically submitted to Seattle Public Utilities (SPU). Testers either submit reports directly through the utility’s official portal or via mail, depending on the city’s current submission requirements.

Some testers may also retain a copy for their records and share one with the property owner. It’s always smart to request a copy for your own documentation.

Does the Tester or Property Owner Submit the Report?

In most cases, the tester is responsible for submitting the report. However, it is ultimately the property owner's responsibility to ensure the test is completed and the results are submitted by the deadline.

If you're unsure whether your report was received, you can contact SPU or your local water provider to confirm.

Does Seattle Use Systems Like BSI, VEPO, or TCE?

Unlike many other cities, Seattle does not currently require testers to use third-party compliance portals like BSI Online, VEPO, or The Compliance Engine (TCE). Most reporting goes directly to SPU, but surrounding cities may use other systems.

Before testing, always double-check with your water provider or the customer's notice to confirm where to submit the results.
