PDX BackflowFind a Tester

What happens if I ignore the backflow testing letter?

It's tempting to set the letter aside, especially if nothing seems to be wrong with your water. But annual backflow testing isn't optional under Oregon law, and water providers have real enforcement authority behind it.

The general escalation path

Water purveyors typically send an initial reminder, followed by additional notices if the test isn't completed by the deadline. According to the Portland Water Bureau's published guidance, if a required backflow assembly isn't installed, tested, or maintained — or if a property owner doesn't respond to a correction notice — the Water Bureau has the authority to shut off water service, sometimes without further notice. Exact timelines and notice requirements can vary, so if you've received a second or "urgent" notice, it's worth calling your water provider directly to confirm your specific deadline.

Why this rule exists

The annual test isn't bureaucratic box-checking — it's the mechanism that confirms the device protecting the shared public water supply from contamination is still working. Water purveyors don't have visibility into whether your assembly is functioning without that test report, which is why non-compliance is treated seriously rather than as a formality.

What to do if you're already past the deadline

Don't wait for the next notice. Getting a test scheduled and the report filed is usually straightforward once you find a certified tester — most can turn around a routine residential test within a few days. Our tester directory lets you call one directly instead of tracking one down yourself.
