Legal Requirements
What Does the Law Say About Backflow Assemblies?
Oregon Administrative Rules on Backflow govern public water systems and includes backflow regulations. The Department of Human Services enforces these rules and approves the types of backflow assemblies that can be installed.

DHS requires the following of property owners:

Install a backflow assembly if there is an existing or potential cross connection.
Test the assembly after installation, annually, and if the assembly is moved or repaired, also a requirement of the State Plumbing Code. A State-certified backflow tester must perform the test, and send copies of the test report to the local water provider. The assembly must function properly to pass the test.
Repair the assembly if it is not functioning properly. A certified tester must retest the assembly after a repair.
The Water providers can deny or discontinue water service if a property owner fails to follow the law.

Yes, back flow prevention devices must be tested annually in most areas. Check your local codes for the specific requirements in your community

Yes, annually here in Philadelphia. It’s a shame I let my cert go because they are ignored so much. There is no reason to keep the cert and little money in the test. The result is dangerous, poorly maintained protection on the water supply. They will get serious when someone dies.
